EXECUTIVE SUMMARY

This study was performed to evaluate the impact of severaltechnical issues related to the usage of the Canister StorageBuilding(CSB) of the Hanford Waste Vitrification Plant<HWVP)Project to safely stage and store N-Reactor spent fuel currentlylocated at K-Basin 100KW and 100KE. Each technical issue formedthe basis for an individual Trade Study that was used to developRough Order Magnitude(ROM) cost and schedule estimates. The studyused Concept 2D from the Fluor Daniel prepared "Staging and StorageFacility (SSF) Feasibility Report", dated February 1995, as thebasis for development of the individual trade studies.

Concept 2D was a variation of Concepts 2A and 2C presented in thefeasibility study. Concept 2D had storage tubes installed in onlytwo of the three vaults, resulting in a total of 440 storage tubes.The storage tubes were fabricated of Corten material. The vaultscontaining tubes were cooled with 35° F refrigerated air during thestaging phase and convective cooling once all the fuel had beenstabilized. The MCO characteristics included 880 MCOs with 8 fuelcanisters stacked four high per MCO and a temperature of 100° F.Heat generation per MCO was 176 W(Nominal) and 328 W(Limit) , basedon an 80% Nominal, 5% Limit and 15% below Nominal distribution.The fuel centerline temperature after stabilization was limited to400° F.

To perform the trade studies WHC requested further modification toConcept 2D, including revising MCO characteristics. Concept 2D wasto be adjusted to accommodate 750 MCOs with 10 fuel canistersstacked five high per MCO with a maximum temperature of 100° F.Heat generation per MCO was increased to 221 W(Nominal) and 482W(Limit), based on an 80% Nominal and 20% Limit distribution.Fluor Daniel was further instructed not to reconfigure the buildingfor 750 MCOs, but to continue on a with 220 storage tube per vaultarrangement. To ensure that worst case loads were used for ourheat load calculations it was assumed that all 220 tubes per vaultwere filled with two MCOs each. The fuel centerline temperatureremained at 400° F after stabilization.

A re-evaluation of Concept 2D with the modifications indicated ispresented in Section 2.0. The results of the re-evaluation foundthat it is not feasible to adapt the current design of the CSB andcomply with the functions and requirements of the SSF. The highheat load per MCO and 80/20 MCO distribution would require 35° Frefrigerated air operating in excess of 500,000 CFM to achieve a105° F MCO temperature, not 100° F as required.

The re-evaluation also highlighted several other technicalchallenges that would need to be overcome to meet operating and


CSB Trade Study Fluor Daniel, Inc.Wescinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

safety concerns. By increasing the allowable MCO temperaturerequirement to 100° F , hydrogen gas production due to water in theMCOs will be increased requiring the tubes to be vented and purgedmore often. The volume of hydrogen gas would be high enough towarrant the purging of nearly 100 tubes per day or roughly 25% ofall tubes would require purging daily during the staging phaseprior to stabilization. The 100° F MCO temperature would furtherexacerbate Microbiological Influenced Corrosion (MIC) reducing thefuel storage time and life of the MCO. The radionuclideconcentrations are also much higher for the revised MCO requiringsignificantly thicker shielding, especially for the facility(handling) cask within the CSB, to ensure worker safety. Theheavier cask will also increase the crane capacities required tohandle the material flow. During conceptual design aninvestigation into remote handling of the MCOs without a cask mightbe given consideration. The dose rates and exposure concerns wouldfurther complicate use of the empty vault in the future. Toprotect personnel in the future it may be required to isolate theempty vault with sufficient shielding at the air intake and exhaustplenum,as well as increase the common wall thickness.

The study also included an evaluation of the technical, cost andschedule impacts to Concept 2D due to eight independent TradeStudies. The estimate for Concept 2D was updated to reflectstructural and mechanical changes. An allowance was left in theestimate for HVAC equipment with the understanding that a changemay occur as a result of the technical feasibility evaluation. Inaddition, the cost of transport and facility casks and the railroaddonkey engine were excluded from the Concept 2D estimate update tomore accurately reflect only facility cost. A summary of the costestimates for each of the Trade Studies in relation to Concept 2Dis provided in Table 1. In terms of the construction schedule, itappears that only Task "H" of the Trade Studies, i.e. RCRAFunctions: Prevention and Detection of MCO leaks, would have animpact on the proposed construction schedule end date indicated inSection 2.5. It is estimated that RCRA compliance would extend thefacility completion date by a minimum of two months. Someintermediate activities may be enhanced by certain other TradeStudies .

1.0 INTRODUCTION

1.1 Background

In January 1995 Westinghouse Hanford Company (WHO commissionedFluor Daniel to investigate the feasibility of adapting thedesign of the HWVP Canister Storage Building (CSB) to meet theneeds of the WHC Spent Nuclear Fuel Project for a Staging andStorage Facility (SSF) and to develop Rough Order of Magnitude(ROM) cost and schedule estimates. The SSF is to store spentN-Reactor fuel in Multi-Canister Overpacks (MCOs) filled withwater until a Stabilization Facility is available to stabilizethe fuel. After stabilization of the fuel the MCOs will bereturned to the SSF for storage until a geologic repository isavailable for final disposal. The study investigated twoconcepts for the SSF which were selected by WHC, 1) the use ofwater cooling prior to stabilization of the fuel followed bypassive dry storage, and 2) the use of refrigerated aircooling prior to stabilization followed by passive drystorage.

The design criteria for the study stipulated that the watertemperature in the MCO prior to stabilization is to be limitedto 50° F maximum and the fuel centerline temperature afterstabilization is to be limited to 400° F maximum.

The study report was completed in late February 1995 and wasissued to WHC. The study found that it is feasible to adaptthe design and partially completed construction of the CSB tomeet the functions and requirements of the SSF using either ofthe specified concepts.

Under Concept 1, the MCOs are stored in racks in a singlelayer in an open pool of water with a recirculating watertreatment system which returns the water to the pool at 44-45°F. This portion of the SSF utilizes approximately 1/3 of thecompleted CSB foundation. The balance of the facility, whichutilizes the remaining 2/3 of the CSB foundation and thedesign of the CSB dry storage vaults, is constructed so thatit is operational at the same time as the StabilizationFacility. After stabilization, the MCOs are returned to thenewly constructed dry storage vaults of the SSF, where theyremain in passive dry storage until a geologic repository isavailable for final disposal.

Two alternatives were evaluated under Concept 1. AlternativeIB provides 512 storage tube locations for dry storage in twovaults and does not require any addition to the CSB foundationfootprint. Alternative 1C provides 660 storage tubes andrequires the addition of space for another vault to the CSBfootprint.

CSS Trade Study • Fluor Daniel, Inc.Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

Under Concept 2, the MCOs are stored in two layers in waterfilled tubes extending into three, below grade, concreteenclosed, shielding vaults cooled by recirculating 35° Frefrigerated air. This utilizes the entire foundation anddesign of the CSB. After stabilization, the storage tubes aredrained of water and the MCOs reinstalled. When all the MCOshave been stabilized, the recirculating refrigerated airsystem is shut down and natural circulation passive aircooling established.

During review of the draft of this report, interest wasexpressed in other alternatives which were not constrained bythe Design Basis. In particular, it was indicated that it waspossible that the 50° F MCO temperature limit prior tostabilization could be relaxed. If this temperature wererelaxed to about 100°F, it would be possible to store the MCOsin dry Corten storage tubes cooled by refrigerated air.Relaxing the MCO temperature limit prior to stabilizationwould not have any significant affect on the design or cost ofthe water cooled alternatives, i.e. Concept 1.

In order to permit evaluation of these other alternativesagainst those previously studied, ROM cost estimates weredeveloped for the following additional alternatives:

Alternative 2C. This alternative is the same as Alternative2A (660 storage tubes) except that the storage tubes are notfilled with water, allowing Corten to be used, which resultsin an MCO temperature of about 100° F when cooled with 35° Frefrigerated air.

Alternative 2D. This Alternative is the same as Alternative2C except that storage tubes are installed in only two of thethree vaults, resulting in a total of 440 storage tubes. Thenumber of storage tubes in two vaults could be increased to512 using the same configuration as for Alternative IB, butthe cost of this was not evaluated. The MCO temperature wouldbe about the same as for Alternative 2C (about 100° F) .

Alternative 2E. This alternative is the same as Alternative2A except that storage tubes are installed in only two of thethree vaults, resulting in a total of 440 storage tubes. Asabove, the number of storage tubes in two vaults could beincreased to 512. The MCO temperature would be about the sameas for Alternative 2A (about 50° F) .

1.2 Study Objectives

The objectives of this study were to determine any newfacility functions and evaluate the impacts to the costestimate, risk and safety issues and design/construction

schedule for Che Concept 2D, i.e. Alternate 2D for the SSFFeasibility Study. This study will be performed concurrentlywith the Spent Nuclear Fuels(SNF) CSB conceptual design effortand be used as basis for development of a conceptual design.

1.3 Scope of Work

Using Fluor Daniel Concept 2D (dry stage/dry store/1000 FMCO/3 vaults one without tubes/Corten tubes) from the FluorDaniel SSF Feasibility Study, dated February 1995, performtrade studies and prepare individual reports documenting theresults of each investigation in accordance with Statement ofWork, Revision 5, dated April 21, 1995, in Attachment 1 of WHCWork Order TVW-SW-370252, Modification No. 90. Use the samecriteria as the SSF Feasibility Study, unless directedotherwise. The trade studies are as follows:

Concept 2D. Adjust for 750 MCOs with 10 canisters stacked 5-high per MCO. Use MCO characteristics defined in Section3.2.2.1.2.2 of WHC-SNF-FRD-014, "Draft PerformanceSpecification for the Spent Nuclear Fuel Canister StorageBuilding", Rev. A, dated May 1995. Do not reconfigure the HWVPCSB storage vaults to support only 750 MCOs. Storage tubequantity should remain at 220 tubes per vault for a total tubecount of 440 tubes (two vaults) . Revise cost and schedule datafrom the SSF Feasibility Study as appropriate.

Task A Further investigate the requirements for SafetyClass 1 confinement of the operating spaces abovethe storage tubes. A negative air pressurerelative to atmospheric pressure is required.Considerations include, but are not limited to,sealing the building, providing airlocks, andadequate capacity exhaust fans to maintain anegative relative air pressure. Refer to the draftPreliminary Safety Evaluation <PSE).

Task B Remove the new MCO receipt and staging, i.e.cask/MCO unloading and storage, function and area.

Task C Remove the cask decontamination, i.e. wash area,function and area.

Task D Simplify rail service to one track with passingtrack outside facility.

Task E Determine the technical feasibility of non-stainless steel water-filled tubes. Recommendmaterial to resist wet corrosion for only 7 yearsversus 40 years.

2.1.2 Rail Tunnel/Cask Unloading Area

2.1.2.1 General Description

The Rail Tunnel/Cask Unloading area is a new addition ofapproximately 10,000 square feet to the original CSB design. It islocated in the north west corner of the CSB and interfaces with theMCO Storage Tube Area via a covered water canal as shown in Figure2-3.

The main functions of this area are to safely receive, handle andprepare the incoming packaged MCO for placement in the storagetubes prior to stabilization. The packaged MCOs are deliveredinside a transport cask, via rail car or truck, one at a time.Before being returned to the K-Basins, the transport casks areprepared for handling and loaded with an empty MCO.

In addition to the underwater transfer canal to transfer MCOs to areceiving station within the operating area of the storage facilitywhere they can be retrieved by the bottom loading MCO shield caskfor transfer to their storage tubes, the Rail Tunnel/Cask Unloading

(2) rail cars outside the facility{2) rail cars in the facility(4) transport casks: (2) clean, ready for use, (l)

contaminated, waiting for decontamination and (l)in the decontamination pit

(28) empty new MCOs(1) empty new MCO overpack

The Rail Tunnel /Cask Unloading Area includes the Wash Area, theCask Unloading and Storage Area, the Cask Preparation Pit, the CaskUnloading Pool, MCO Transfer Canal, MCO Transfer* Canal Cart and theCask Loading Pit.

A remotely operated hot cell type facility was considered as analternative to the Cask Preparation Pit/Cask Unloading Pool/MCOTransfer Canal/Cask Loading Pit, but was expected to be more costlyand was therefore not considered further.

2.1.2.2 Wash Area

The Wash Area is a air lock confinement area where the incomingrailroad cars and delivery truck/trailer are washed prior enteringthe Cask Unloading and Storage Area. Two railroad cars, and thedonkey engine, and a truck trailer parked in parallel can beaccommodated inside. A permanent ceiling installed liquid sprayarrangement allows wash/decon of the shipping cask upper section.Hand held wash/decon lances are available for the lower areas.Wash water can be pumped out of one or more sumps into a hold tankfor monitoring, before being sent through the non-radioactive drainline to the 200 area.

2.1.2.3 Cask Unloading and Storage Area

The Cask Unloading and Storage Area is designed for unloading andloading transport casks and for handling and storage of empty MCOs.Two railroad cars, one truck trailer, twenty eight MCOs, one MCOoverpack and two clean ready to use shipping casks can beaccommodated in this area. A cask unloading overhead crane, withan auxiliary hoist, running in the west/east direction servicesthis area. A fifteen foot tall wall partially isolates this areafrom the Cask Preparation Pit, the Cask Unloading Pool, MCOTransfer Canal and the Cask Loading Pit, but allows the passage ofthe overhead crane above it.

2.1.2.4 Cask Preparation Pit

The Cask Preparation Pit is dedicated to the preparation ofshipping casks for unloading, which consists primarily of unboltingthe cask cover. A sleeve, anchored to the bottom of the pit,

receives and restrains the cask. Access working platforms areaffixed to the upper interior walls of the pit. The overhead craneis used to handle the cask. The* Cask Preparation Pic could also beused for additional cask decontamination or other pre-unloadingservices if necessary.

2.1.2.5 Cask Unloading Pool/MCO Transfer Canal

The Cask Unloading Pool, adjacent to the Cask Preparation Pit westend, is dedicated to unloading MCOs from their casks, MCO servicingand placing defective MCOs in an overpack. Underwater fixtures areprovided to support the cask cover and two MCOs during servicing.Required MCO servicing is performed underwater* at this location,using specially designed tools as described in Section 2.1.3. Anopening, i.e. MCO Transfer Canal, through the common wall separatingthe Unloading Pool with the MCO Storage Area Transfer Canal Poolallows underwater transfer of MCO's from one pool to the other. Tominimize cross contamination to the MCO Storage Area Transfer CanalPool, the pool water return flow is directed toward the UnloadingPool. In case contamination is detected in the Unloading Pool aportable gate can be placed in the wall opening to isolate the twopools. When retrieving an empty cask from the pool, the water inthe cask is drained above the Unloading Pool using special tools.The overhead crane is used to handle the cask and the portablegate. The auxiliary hoist is used to handle the cask cover, MCOand overpack.

The underwater transfer of the MCO from the Unloading Pool to theStorage Area Transfer Canal Pool is accomplished using the MCOTransfer Canal Cart.

2.1:2.6 Cask Loading Pit

The Cask Loading Pit, similar in construction to the CaskPreparation Pit, is located west of the Cask Unloading Pool and isdedicated to cask preparation for return to the K-basins. With thecover removed, the cask is decontaminated, and an empty MCO isloaded inside the cask. The gap between cask cavity and MCO isfilled with deionized water. Finally the cask cover is bolted onand decontaminated if necessary. The now ready to use cask istransferred to a storage position or to an empty railroad carlocated in the Cask Loading and Storage area.

2.1.3 MCO Servicing

2.1.3.1 Functional Description

After each MCO is received into the SSF for staging, the MCO willbe purged with nitrogen, then deionized water will be added ifneeded to reach the desired level in the MCO. The servicing willbe done with the MCO submerged in the Cask Unloading Pool. A pool

C3E Trade Stuc.y Fluor Daniel, m e ,West:.ngr.ouse Kanford Company Government: ServicesWHC! P.O. TVW-SW-370252 Contract 04436306

water treatment system will maintain pool temperature, clarity, andradioactive contamination at acceptable levels.

2.1.3.2 System Design Requirements

Once all MCOs have been received, only water-filled MCOs will needto be serviced. Based on the water reaction rate with, uranium andthe evaporation rate at 100 °F, the worst MCO must be serviced atleast every 300 days. Since there is no means of determining thewater level within an MCO, a conservative schedule must beestablished to ensure that the top canister in the most active MCOdoes not become dry. This requires servicing at least 3 MCOs perday, starting within 300 days after placement.- For water-filledMCOs, it was assumed that the hydrogen inside each MCO does notconstitute a hazard, assuming the MCOs are designed so they willnot release gas in the event of a Design Basis Accident (if thisassumption is incorrect, then more than 500 MCOs per day must bepurged in order to keep hydrogen concentrations below the hazardouslevel of 6%. The pool water will provide sufficient shielding foroperators above the pool to assist in making the necessary pipingor hose connections to the MCO using specially designed tools.Water will flow into the servicing area from the MCO Storage AreaTransfer Canal Pool, then back to the pool treatment system. Thecontainment and confinement requirements for this area are asdefined in ANSI/ANS Standard 57-7. Because of the greater chancefor contamination of the pool when MCO valves are opened, the waterturnover time in the service area is 36 hr, half that of the ANSIStandard requirement.

2.1.3.3 Design Assumptions

The- MCO will be designed so that a grapple can be attached fortransporting it underwater without the cask. The MCO will have atleast three valved connections that can be remotely connected topiping or hoses, with each valve capable of remote operation (seeFigure 2-4) . One of the connections will have an interior dip tubewhich extends a known length below the desired water level (butabove any sludge) , and another connection will terminate at the topof the MCO, so that a differential pressure sensor in the servicearea can determine the MCO water level. One of the differentialpressure legs will also be used for nitrogen purging, describedbelow. The third valved connection will allow the MCO to be filledwhile the water level is monitored.

2.1.3.4 Mechanical Design and Operation

The servicing of 4 MCOs per day requires two service stations inthe servicing area. Each station is equipped with a gas collectionpot, filter, piping, and instruments that must be connected to theMCO for servicing. The station is attached by flexible hoses tofixed piping for nitrogen, water, and vent gas. The basic

2-7


CSS Trace Stuc.y "..uor -•ar.:.e-, 7. .c.WA.st:.nghouse E-:anford Company Government ServicesWHC P.O. TVW-.EW-370252 Contract 0443(5306

components of a station are shown on Figure 2-4. The systemequipment list (Table 2-1) indicates the major items needed for thetwo stations as well as auxiliary equipment that supports thefunction of the stations.

The cask unloading crane brings the shielding cask with MCO intothe Cask Unloading Pool. The cask provides operator shieldinguntil the cask is covered by at least 8 ft of water. After thecrane removes the cask lid and places the MCO on an underwaterstand for servicing, the operator manually positions the servicingpiping assembly onto the MCO, remotely couples the piping to theMCO connections and prepares to operate the MCO valves. The ventgas pressure and contamination level are monitored before the gasis released through a HEPA filter to the operating area buildingstack. Upstream of the HEPA filter is a shielded gas collectionpot which will serve as a radiation monitor source, catch anyentrained liquid in the vent gas, and provide capability for gassampling. After the pressure in the MCO is released, sufficientnitrogen is purged through the MCO to reduce the hydrogenconcentration to 1% by volume or less. After purging, thenitrogen flow is reduced in order to measure the level of water inthe MCO. Nitrogen is stored in cylinders delivered by truck to arack outside the building. If needed, deionized water is added bya metering pump through the collection pot in order to flush anycontamination back into the MCO. The valves on the MCO are closedafter servicing, the service station is disconnected, and the MCOis transported underwater by the MCO Transfer Canal Cart into theMCO Storage Area Transfer Canal Pool.

2.1.4 Cask Unloading Pool Water Treatment System

2.1-.4.1 Functional Description

After each MCO is received and passed through the Cask PreparationPit, the MCO will be placed in the Cask Unloading Pool. The poolwater provides shielding and cooling for the worst case. The poolwater treatment system will maintain pool temperature, clarity, andradioactive contamination at acceptable levels. Although noleakage is expected from MCOs or system components, the pool andits water treatment system are designed to minimize radiationexposure in the event of leakage due to a credible accident.

2.1.4.2 System Design Requirements

The nominal value of heat generation per MCO is 221 W and themaximum value is 482 W. At 100 °F the maximum MCO produces near 40L/day of hydrogen gas contaminated with 4.62 mCi/L of Kr-85. Thenominal values apply to 80% of the MCOs, the upper limits apply to20%. There are no particulates or condensible vapors generatedduring non-accident conditions. The total system cooling duty isbased on the maximum MCO.

The pool is lined with stainless steel to ensure water purity, toprevent water migration through the concrete pool structure, and toallow decontamination at the end of the facility life. Asrecommended by DOE Order 6430.1A, Section 1320, the liner has aleak detection system with a collection sump in the concretestructure.

The water treatment system returns water which has been purifiedand cooled to 95 °F. This will maintain the MCO at 100 °F or lessunder normal conditions. The system has sufficient redundancy (orelse contingency back-up capability within the available responsetime) so that a single failure of any active component {such as apump, filter, or control) will not cause loss of system function.The following requirements of ANSI/ANS 57.7 and NRC Reg Guide 3.49are met: Clarity will be sufficient to clearly see to the bottomof the pool. Contamination will be maintained at an annual averagegross activity level of 5 x 10"* mCi/L or less during normaloperation. The recirculation rate is sufficient to turnover thepool volume in 36 hours and the deionization units will not beregenerated. The piping is designed so that water will not siphonout of the pool in the event of a piping leak. Because of thesmall size of the units, the resin beds are replaced when theybecome saturated.

The system will maintain a safe condition after loss of normalpower, loss of cooling, and Design Basis Accidents such asearthquake,- in these cases, credit will be taken for portableequipment that can be moved in during the period of time beforetemperatures, hydrogen concentration, or contamination levelsexceed safe levels. The clean-up system will have the capacity forthe worst-credible release of contamination into the pool.

2.1.4.3 Design Assumptions

The MCO will be designed so that a grapple can be attached fortransporting it underwater without the cask. The laboratoryrequired for periodic analysis of pool water samples is not part ofthis facility. Fresh make-up to the deionizer will come from thesite sanitary water, containing 95.1 ppm dissolved solids, lessthan 10 ppm suspended solids, pH 7.80, and CaCOa hardness of 73.46ppm.

2.1.4.4 Mechanical Design and Operation

Figure 2-3 shows the arrangement of the Cask Unloading Pool andassociated areas. MCOs are transported to and from the caskunloading pool by the MCO Transfer Cart. The depth of water abovethe MCO Transfer Cart allows the MCO being transported to becovered by 8 ft of water at all times.

Refer to Figure 2-5, the block diagram for pool water treatment andcooling. The pool water treatment system consists of pool skimmersand flow distribution piping, recirculation pumps, high-efficiencyfilters, filter backwash equipment, deionization units,deionization unit replacement, waste slurry holding, waste waterholding, water chillers, and water sterilizers.

Table 2-2 lists the major equipment for the pool water treatmentsystem. The skimmers remove floating debris from the caskunloading pool. Inlet and outlet piping for the pool is designedto provide distribution of flow through the pool with minimumpressure loss. One operating pump and one spare provide a 36 hrturnover of the pool volume during normal* operation. Ifcontamination in the pool becomes abnormally high, both pumps canbe operated to increase the recirculation rate. The filters arenuclear-grade filters with a particle capture size of one micron.Compressed air at 300 psig will be produced to improve backwashingand to supply the facility instrument air system. Stainless steelmaterial was chosen for the compressed air to avoid getting pipescale particles on the clean side of the filters during backwash.The deionization unit is a duplex package of two trains, so thatone train can remain in operation while the other is out ofservice. Each train removes both anions and cations (positivelyand negat ively charged ions) from the water in res in beds. I fcontamination in the pool becomes abnormally high, both trains canbe temporarily operated in parallel to increase the recirculationrate. The design of the filters and deionizers for accidentconditions is discussed in section 2.2.3.3. Normally, deionizationresin replacement is required less than once per year.

Pool water treatment system drainage will go to the waste waterhold tank to be neutralized and monitored before being picked up bya truck with a pump. Pool water filtrate slurry will go to thecontaminated waste slurry hold tank to be monitored before beingpressurized into a shielded container on a truck, using compressedair. Fresh resin can be exchanged into the deionization units fromthe shielded room containing the units. Separate curbed areas areprovided for truck loading and unloading at the tanks for wastewater and contaminated waste slurry.

Each chiller is sized for the maximum heat input from the MCO, heatgains from the surroundings, and the dissipated energy from the 10hp recirculating pump. A 100% spare chiller and heat exchanger isprovided, although interruptions in cooling can be tolerated. Inthe event of loss of cooling, the pool requires over 165 hours towarm up 10 °F. However, recovery from an overheated conditionrequires some spare cooling capacity. The pool water sterilizers,along with chemical addition, inhibit biological growth which wouldcloud the water. The glass in the ultraviolet sterilizers willrequire regular cleaning.The equipment used to detect excessive

2.1.5 MCO Cooling and HVAC

2.1.5.1 HVAC Systems for Normal Operation

Vault Refrigerated Air System. The block flow diagram for the HVACsystem serving the SSF Vaults during staging is shown on Figure 2-6. The HVAC system is a recirculating refrigerated air systemconsisting of five 50,000 CFM Air Handling Units (4-operating andl-standby) which supply chilled air at 35 °F to the vault. Thissupply air temperature to the vault will maintain the MCOs at111 °F. The 111 °F does not comply with current MCO temperature{100 DF) requirements, but is used as the basis for the ROM costestimate. Since the MCO's are stored in dry air filled Cortentubes which serve as a secondary confinement barrier, the airinside the vault will not be contaminated.

Vault Passive Ventilation System. The passive ventilation systemfor the vault during dry storage will be identical to the CSBdesign. This concept has two vaults, each with 220 tubes. Thereare provisions for 11 overpacks and the tube spacing for thisconcept will be identical to the CSB design. A third vault isprovided as in the original CSB design, however, no tubes will beinstalled.

Operating Area HVAC System. The Operating Area HVAC System for theCSB design will be modified to accommodate the ventilation systemfor the MCO service area and the MCO/Cask unloading and storagearea. The system is capable of diluting the hydrogen and krypton-85 'to acceptable levels by introducing sufficient amounts ofoutside air. The block flow diagram for this system is depicted inFigure 2-7) .

Pool Water Treatment Building. This building consists of cleanareas and potentially contaminated areas. A single HVAC systemwill be used to serve these areas.

The block flow diagram for the HVAC system serving these areas isshown on Figure 2-8. Redundant 2,000 CFM Air Handling Units (AHU-1and AHU-2) with evaporative cooler and heating coil supply air tothese areas and the air is exhausted through redundant HEPA filterplenums (PF-1 and PF-2) and exhaust fans (EF-1 and EF-2).

2.1.5.2 HVAC Systems for Abnormal Operation

Vault Refrigerated Air System. It has been estimated that onfailure of the vault refrigerated air system used during staging,the MCO temperature will increase by 30 °F in approximately 20hours. Concept 2D is currently not a safety class system.

Adequate time would mostly likely not be available in the event ofa sustained loss of refrigerated air cooling to bring in mobileemergency cooling capability before MCO temperatures becameexcessive.

Vault Passive Ventilation System. The vault passive ventilationsystem used during dry storage is designed to operate following allDBA's. No other HVAC systems are required for operation of thevaults during abnormal operation.

Operating Area. The block flow diagram for the HVAC system foremergency ventilation of the Operating Area is shown on Figure 2-9) . This system is designed to be activated following an accident(potential drop of an MCO and release of contamination to theoperating area) and is interlocked to stop the normally operatingHVAC system. The HVAC system consists of two trains with HEPAfilter plenums (PF-l and PF-2) and exhaust fans (EF-1 and EF-2).

2.1.6 Structural

The CSB below grade concrete vaults and the operating floor willessentially remain the same as originally designed. Vaults 1 and 2will be used for the staging and storage of the MCOs containingSNF, and vault 3 will remain empty for future storage of undefinedmaterial. The existing 3 feet east-west wall between vaults 2 & 3must be increased to 42" to provide adequate shielding protectionto persons entering the vault 3 for activation at a later date.Preliminary HVAC calculations indicate that the concrete surfacetemperature inside the vaults during staging and support phaseswill not exceed 150°F. Therefore, the insulating concrete may bedeleted from the original design. Also the 1 inch metallic traffictopping over the concrete operating floor will be replaced with aless expensive concrete sealer / hardener since the MCOs are to behandled by crane and not by shielded transporters. The structuralconsequence of dropping the facility cask containing MCO from a 3foot height on the operating floor will require further evaluationincluding a crane with features to prevent a drop. The storagetubes will be of Corten material similar to those designed for theCSB.

The existing design of the steel shelter over the operating floorwill be modified to include crane rails and girders for theoverhead crane for the cask/MCO handling system. This buildingheight will be increased by approximately 12 feet and the currentlydesigned steel columns and portion of roof trusses members will bereplaced with stronger sections. The north wall of the operatingbuilding may require relocation north by approximately 8'-0" toaccommodate crane operation. The Cask/MCO Unloading and StorageArea Building is approximately 170 feet long, 61 feet wide, and 33ft high. This building will have an overhead crane for unloading

an-i loading of casks and MCOs. Within this building is below gradecask unloading and MCO transfer pool. The concrete pit floor andwalls will be lined with 1/4 inch and 3/16 inch stainless steelplate respectively, complete with leak detection system.The WashArea Building is approximately 64 feet long, 50 feet wide and 27feet high. These buildings will be constructed of structural steelframing enclosed by insulated metal siding and metal roof deck.

The Pool Water Treatment & Instrument Air Compressor Building isapproximately 35 by 30 by 17 feet high steel structure. TheEquipment /Office/Generator Area Building will be a steel framebuilding and similar in construction to the existing CSBequipment/of f ice area building except, the size will beapproximately 100 by 33 by 17 feet high. The Refrigerated AirMechanical Area Building is approximately 120 by 40 by 20 feet highsteel framed structure enclosed by insulated metal siding andmetal roof deck.

An HVAC duct, approximately 10 ft by 5 ft in size will be addedconnecting the exhaust stack and the Refrigerated Air MechanicalArea. This duct will be supported by the operating shelter.Refrigerated air will be returned to the air inlet ducts via ductsfrom the Refrigerated Air Mechanical Area. Removable blinds in theair inlet ducts and exhaust stack will isolate the refrigerated airsystem from the environment. The inlet air temperature to thevault will be about 35°F during the staging phase.

The preliminary safety classification of the SSCs for the stagingand storage phases is defined in Tables 2-9 and 2-10 respectively.

2.1:7 Material Flow

2.1.7.1 General Description

The Material Flow includes two distinct phases: the StagingMaterial Flow and the Storage Material Flow which takes place onlyafter completion of the Stabilization Facility.

2.1.7.2 Staging Material Flow

The Staging Material Flow involves tasks and sequences necessary toplace packaged MCOs, received from the K-Basins, into forced aircooled storage tubes in the Storage Tube Area, prior tostabilization.

The Staging Material Flow begins with a packaged MCO in a cask, ontop of a rail road car or truck parked outside the Rail Tunnel/CaskUnloading Area. It terminates at the removal, from the facility,of a decontaminated cask loaded with an empty, ready to use, MCO.

2-21


CSB Trade Scudy Fluor Daniel , I nc .Westinghouse Hanford Company Government Serv icesWHC P.O. TVW-SW-370252 Contract 04436306

Figures 2-10 through 2-13 depict the tasks, sequences, equipmentand estimated time required to perform the tasks.

It is assumed that placement of the bottom impact absorbers insidethe storage tubes is performed during the completion ofconstruction. The upper impact absorbers are assumed to beinstalled in a campaign style manner during a down time period.

2.1.7.3 Storage Material Flow

The storage material flow involves tasks and sequences for storingstabilized MCOs inside dry, passively cooled storage tubes. Thesetubes being the same used for the prior staging'phase. This phasewill occur only after the Stabilization Facility has been madeoperative.

The Storage Material Flow begins with the removal of an MCO from astorage tube and its transfer to the Stabilization Facility. Itterminates with closure of a dry storage tube after loading astabilized MCO in it. If required, MCOs can be retrieved and sentto the Stabilization Facility for overpacking by reversing thesequences order. Figures 2-14 and 2-15 depict the tasks,sequences / equipment and estimated time required to perform thetasks.

It is assumed that removal and replacement of the upper impactabsorbers inside the storage tubes is performed outside the MCOhandling time frame. The bottom impact absorbers remain in placeand do not require handling. The upper impact absorbers areassumed to be removed and reinstalled in a campaign style manner,during a down time period.

2.1.7.4 Overhead Crane Design and Operation

For loading MCOs into the storage tubes in the SSF drystaging/storage vaults an overhead crane with associated casks andfixtures will be used. The overhead crane system is similar tomethods used in Europe and at the Fort St. Vrain Fuel StorageFacility. Other methods for loading the storage tubes arepossible, i.e. a Shielded Canister Transporter(SCT) as was designedfor HWVP/CSB, but were deemed less attractive for this application.

The size and weight of the MCO will have an affect on the handlingequipment and overall capital and operating cost of the systemadopted. Two different size MCOs were considered in thisevaluation:

1) A 10 canister MCO, 181 inches long, weighing 11,600 lbs.

2) A 10 canister MCO, 181 inches long, weighing 13,100 lbs.

The equipment required for the transfer systems associated witheach of the above MCOs is described in Tables 2-3 and 2-4. Figure2-16 describes the possible operation of this equipment. Caskweights were based on the requirements defined in Section 2.8,Design Basis, Section 3.2.2.1.2.2 of WHC-SNF-FWD-014, "DraftPerformance Specification for the Spent Nuclear Fuel CanisterStorage Building", Rev. A, dated May 1995. Crane capacities wereestimated based on the heaviest loads to be lifted including theweight of the cask based on shielding requirements defined inSection 2.2.5.7, and the safety margins required for critical liftsat Hanford. The SSF crane capacity was based on a safety margin of125% of the heaviest lift anticipated.

The MCO shield cask is a bottom loading cask that incorporates anMCO grapple and hoist assembly. It would be positioned above ashield gate located above a selected SSF storage tube. The storagetube shield plug is handled (removed and installed) using ahandling flask. This system is similar to that employed at theFort St. Vrain fuel storage facility and at several locations inEurope. The MCO Transfer Canal will be the point of entry for theMCO for the overhead crane/cask method. This station would requirea floor plug shield gate.

The overhead cask/crane method will require a means to transportthe MCO to the Stabilization Plant. If the Stabilization Plant isclose coupled to the dry storage facility an unshielded transfercart operating in a below grade tunnel can be used to make thetransfer similar to in Figure 2-16. If the Stabilization Plant isat a distant location, a top-loading shipping cask can be used.

The overhead cask/crane will require four basic components to loadthe' canisters into the SSF storage tubes,

1) The bottom loading MCO shield cask2) The floor plug shield gate3) The portable shielded floor plug handling flask4) The 120T overhead bridge crane with 10T auxiliary hoist

The bottom loading MCO shield cask will contain an integral hoistand grapple system to handle the MCO. It will incorporate a shieldgate at the bottom and a ventilation system to control theatmosphere within the storage tube during MCO transfer.

The floor plug shield gate is used to seal and shield the storagetube when the tube's shield plug is removed. The gate is locatedover the desired storage tube using the overhead bridge crane. Theportable shielded floor plug handling flask is then mated with thetop of the shield gate. A grapple within the flask is used to liftthe plug thru the open shield gate. The gate is then closed andthe flask containing the plug removed. The storage tube is nowready for installation of the MCO.

2.2 FEASIBILITY ISSUES

2.2.1 Structural

The SSF Feasibility Study final report dated February 1995(Reference FDI transmittal No. FRT-2604) had enumerated on twostructural issues: (a) seismic criteria change; (b) existing CSBconfiguration/design adaption. With respect to the seismic criteriaWHC has confirmed that the basis for design will be Hanford PlantStandard SDC 4.1, Revision 12 as specified in the Draft PerformanceSpecification document WHC-SNF-FRD-014. The design and evaluationof the SSCs will be based on UCRL 15910 as Hanford site has notimplemented the replacement document DOE-STD- 1020-94. The CSB hadbeen designed to 0.35g PGA and there should be little impact tothe concrete vault design for adaption to SNF SSF. The operatingfloor shelter will have to be redesigned for the 12 feet increasein height and addition of bridge crane lead.

Further, the document " Implementation Strategies for U.S. DOEOrder 5480.28 Natural Phenomena Hazards Mitigation" by Tom Conradsof WHC, has correlated WHC safety class 1 (high hazard) as equal toperformance category (PC) 3 of DOE Order 5480.28. For PC-3 theearthquake return period is 2000 years in DOE-STD-1020, whereas inUCRL 15910 the return period is 5000 years for high hazard {WHCSC-1) usage. From Figure 5-lb of Geomatrix Consultants report"Probabilistic Seismic Hazard Analysis" (Project No. 2169, May1993), the PGA for 2000 year return is 0.19g and for 5000 yearreturn is 0.28g. These values when multiplied by 1.25 scale factor,as given in DOE-STD-1020, will give design PGA of 0.24g for PC-3and 0.35g for UCRL high hazard usage facility. Therefore, DOE-STD-1020 PC-3 level earthquake forces are much less than UCRL 15910high hazard class provided the correlation of PC-3 with WHC SC-lasstated my Mr. Conrads is correct.

The MCO/Cask drop over the operating floor during crane handlingwill require further evaluation including a crane with features toprevent a drop. Also as-built drawings of the partiallyconstructed CSB need to be developed prior to start of detaileddesign. Field inspection of the existing construction by anexperienced structural engineer is recommended to evaluate any sign

of rebar corrosion that may have initiated since the stop of workin 1.992. An optional Gantry crane handling of the MCO/GasJc overthe vault area should be investigated during conceptual design.

The performance specification WHC-SNF-FRD-014 requires the SC-1structures design life as 2 00 years. This new requirement willrequire further investigation of the concrete degradation due tovarious factors such as temperature, wet-dry exposure, reactivechemicals in aggregates, sulfates in soil, etc.

2.2.2 Thermal /HVAC

This section documents the results of a series of thermal analysesthat were performed to assess the feasibility of meeting the Multi-Canister Overpack (MCO) temperature requirements during wet and drystorage with the Concept 2D Staging and Storage Facility (SSF).These analyses were performed for forced refrigerated air andpassive ventilation systems.

The thermal feasibility analyses is based on storage of MCO's indry air filled tubes in vaults 1 and 2 with a forced refrigerationair cooling of the tubes during staging. MCO's are removed andreturned to the tubes after stabilization. After all fuel isstabilized, the passive air ventilation system is made operational.Vault 3 will contain no storage tubes.

2.2.2.1 Design Basis Assumptions

The following design basis assumptions were used for the thermalanalyses:

• The heat generation rate was based on a total 880 MCO's.Twenty (20) percent are assumed to be at the upper limit(maximum) (482 W) and the remaining 80% are assumed to be atthe nominal (average) value (221 W) . Due to the preliminarynature of the heat transfer calculations a ten percent safetyfactor was used for the heat generation rate. Additional heatloads were added for building heat gains and fan heat.

• The heat generation for the limiting case (482 W) per MCO wasused for the calculating the MCO's temperature assuming thatit is located at the end of the vault.

• The design basis required storage conditions are as follows:

Staging: The MCO temperature at 100 °F.Storage: Maximum fuel centerline temperature at 400 °F.

• During the staging operation the MCO provides primaryconfinement and the dry air filled storage tubes provide the

secondary-confinement. It is assumed that the interior ot thestorage tubes are isolated from the vault, which would preventthe vault from getting contaminated.

• The total flow is assumed to be evenly and uniformlydistributed around each of the containment tubes. This is acritical assumption that must be assured by design andverified by additional analyses using Computational FluidDynamic (CFD) techniques.

• The heat transfer coefficients for air were calculated at thepoint of maximum vault air temperature.

• One dimensional (radial) heat transfer only. Two-dimensional(radial and axial) heat transfer was not modeled.

• Heat transfer by radiation between the tubes was notconsidered.

2.2.2.2 Summary of Results:

The results of the thermal analyses during staging are shown inTable 2-5 and involve various combinations of MCO's surrounded byair in tubes for different ventilation flow rates. The analyseswere performed for 35 °F and 50 °F supply air.

The results indicate that it is not feasible to maintain the MCOtemperature at 100 °F with a refrigerated forced air ventilationsystem. This system would require 200,000 to 500,000 CFM at asupply air temperature of 35 °F based on the above heat generationrate to maintain the MCO temperature between 105 °F and 111 °F. Thetemperature of 35 °F was selected to prevent freezing of MCO'shaving very low heat generation. The MCO temperature is calculatedon the basis that the MCO is located at the end of the vault withthe limiting heat load.

The results of the thermal analyses during storage operation withthe existing CSB design concept, assuming the same intakestructure, vault size and exhaust stack (height and diameter)indicate that an MCO fuel centerline temperature of 270 °F can bemaintained by a passive ventilation system. This is based on aninlet air temperature of 115 °F (same design basis as CSB) and aventilation flow rate of 53,000 CFM. The vault air temperaturedistribution and velocity profile for a fully loaded vault duringpassive ventilation are shown in Figures 2-17 and 2-18.

The above results demonstrate that it is not feasible to use therefrigerated air system to maintain the MCO temperature below100 °F during the staging operation. However, the passive

ventilation systems can maintain the MCO temperature below the 400°F limit during the storage operation.

It must be emphasized that these are rough conservative feasibility-analyses using limited design information and do not cover alllimiting or upset conditions. More detailed analyses are requiredusing CFD techniques to cover all limiting and upset conditions andto verify some basic assumptions. Also no analysis was performedfor MCO's stored in an overpack.

2.2.3 Contamination Control

2.2.3.1 Introduction

The potential hazards are from gas normally generated by the MCOsbefore stabilization and from the unlikely failure of an MCO tocontain the spent fuel. The feasibility concern is whether theMCOs can be cooled and vented while maintaining acceptableconfinement/containment.

The unstabilized MCOs normally generate decay heat and hydrogengas. The gas is contaminated and the rate of gas generationroughly doubles for every 1O°C (18 °F). The gas must be releasedfrom the MCOs without creating a fire or explosion hazard andwithout exceeding acceptable levels of contamination in occupiedareas. The MCOs must be cooled to reduce the rate of gasgeneration and to prevent the MCOs from drying out. If the watercontained in the unstabilized MCOs evaporates and uranium metal oruranium hydride from the fuel is exposed to air, there is a hazardof pyrophoric reaction. This intense reaction could melt the MCOshell, causing the release of fine particles of oxidized fuelcontaining radionuclides.

The remainder of this section discusses confinement and containmentissues during normal MCO venting or accident conditions duringstaging and storage.

2.2.3.2 Normal Operation

MCO Servicing. The MCOs require servicing after receipt from theK-Basins prior to staging: After each MCO is received into theSSF, the MCO is purged with nitrogen and deionized water is addedif needed to reach the desired level in the MCO. The services canbe done with the MCO submerged in the Cask Unloading Pool. Thepool temperature, clarity, and radioactive contamination must bemaintained at acceptable levels; also, the level of contaminationabove the pool must be acceptable for controlled occupancy. Theissues concerning gas and liquid releases from the MCO whilesubmerged are discussed in Section 2.2.3.1. The design includesthe normal building ventilation system for dilution of hydrogen and

2-39



krypton-85, and an MCO servicing system that vents MCO gas to astack and prevents overfilling of MCOs.

Closed Tube Staging. During abnormal operation, i.e. when thefloor plug is removed, gas vented from the MCOs rises through thestorage tube to reach the operating area, which is normally-ventilated with enough fresh air (over 10,000 cfm) to dilute thehydrogen and krypton-85 to acceptable levels. However, since thestorage tube is normally an enclosed space in which hydrogen couldaccumulate, provisions must be made to ensure that explosiveconcentrations do not develop. The following paragraph describesone concept for achieving this objective.

Each storage tube has a sealed floor plug with an embedded ventline and two test lines. The test lines have normally-closedvalves and the vent line contains a HEPA filter. The tubes asoriginally designed can contain a pressure of almost 5 psig beforethe plug lifts from its sealed seat; the tube wall and bellows weredesigned for higher pressures. It would be simple to add a reliefdevice to each vent line so that the vent would only be used if thepressure in the tube were to rise to about 4 psig. With a localpressure indicator added to each tube plug, pressures could bemonitored and a portable cart used to sample and purge each tubewith nitrogen. The cart would consist of a nitrogen cylinder onwheels, a regulator, a vent HEPA filter (similar to the one in thetube plug) , and half-inch hoses to connect to the test lines on theplug. As long as each tube is vented and purged with nitrogenbefore the pressure rises above 0.8 psig, the hydrogenconcentration will not exceed 6% by volume. A 6% mixture ofhydrogen in nitrogen is non-flammable when mixed with anyproportion of air. At the nominal design hydrogen generation rate,a tube with one MCO takes 4.8 days to reach 0.8 psig after ventingand purging. With 750 MCOs staged in 375 tubes, an average of 78tubes per day would have to be vented and purged to maintain non-hazardous mixtures of hydrogen in the tubes.

Passive Air-Cooled Storage. After stabilization, the MCOs do notnormally vent gas. There are no contamination issues during normaloperation.

2.2.3.3 Abnormal Operation

MCO Servicing. The Cask Unloading Pool could become contaminatedin the event of the failure of an MCO during unloading orservicing. Until the accident is quantified, it is assumed thatthe unmitigated consequences are severe enough to require safetyclass 1 or 2 systems, as defined in WHC document MRP 5.46 and DOEOrder 6430.1A. To prevent this potential contamination fromreaching the soil, the pit must be lined with stainless steel andmonitored for leakage. Any place where pit water is contained,there must be a way to inspect or test for leaks; this includes anypiping that penetrates through walls or the ground. The glycol

2-40


_S3 Oracle Study Fluor Daniel, Inc.WesC:.ngt\ause Hanford Company Government ServicesWKC P.O. TVW-SW-370252 Contract 04436306

coolant in the chillers must have monitors or test connections todetect any leaks across the glycol/pit water heat exchangers.

The operating area above the pit could become contaminated in theevent of a crane accident during cask or MCO handling. Should anyabnormal contamination be detected above the pool, alarms warn theoperators to leave the area and the Emergency Ventilation System isactivated. This system ensures that there is no unfiltered releasefrom the building and that the hydrogen concentration remainsorders of magnitude below the flammable limit.

The dropping of an MCO in the pool is not the worst MCO accident(compared, for example, to an accident during MCO handling abovethe storage tube operating floor) , but this accident is a basis fordesigning the pool water treatment system. The pool water filtersand deionizers are sized to contain the upper limit corrosionproducts from an MCO. The soluble corrosion products (cesiumhydroxide) do not pose a criticality threat in the deionizer. Thecritically-safe geometry for the filters has not been determined inthis study, due to time limitations.

Closed Tube Staging. If there is a failure of an MCO duringstaging, the HEPA filter in the sealed tube plug will preventairborne contamination from spreading out of the tube. The tubeplugs have test fittings which allow for periodic water sampling todetect MCO failure. The contamination is localized, but there isno built-in design feature for clean-up.

Passive Air-Cooled Storage. If there is a failure of a stabilizedMCO during storage in a tube, only one tube becomes contaminated.The floor plugs have HEPA filters and test fittings which allow forperiodic gas sampling to detect MCO failure. The contamination islocalized, but there is no built-in design feature for clean-up.

2.2.4 Criticality


One of the issues identified at the start of the SSF FeasibilityStudy was the minimum allowable spacing between MCO's, from acriticality standpoint, and the identification of a feasiblestorage configuration based on criticality considerations. Some ofthe conclusions reached as part of other concepts within the SSFFeasibility Study are applicable to Concept 2D and are addressedherein. Since criticality safety was identified as a potentialdesign driver, an analysis effort was undertaken to identify andquantify restrictions on N-Reactor fuel storage configurationsbased on criticality. Although the Design Basis contained inSection 2.8 indicates that there are no restrictions on MCO spacing

2-41

and stacking based on criticality, it was decided to continue theanalyses to verify the Design Basis.

2.2.4.2 Summary of Results

Preliminary criticality calculations were performed with simplifiedgeometries, talcing no credit for structural material, such ascanister and MCO walls, and all simplifying assumptions made wereconservative. These calculations confirmed that the MCO's could bestacked, even when loaded with five layers of canisters, and can beplaced side-by-side without additional space between MCO's. Theworst-case k.fC calculated was less than 0.90, well within the 0.95limit imposed by the Nuclear Criticality Safety Manual, Section2.0, Paragraph 5.1.3, Allowed Maximum Calculated K-effective.

2.2.4.3 Criteria and Assumptions

The criteria and standards on which these criticality calculationsare based, as well as the assumption used in formulating thecomputations, are given the following paragraphs.

Applicable Orders and Standards. The criticality calculationsperformed in support of this feasibility study conform with thefollowing criteria and standards:

DOE Order 5480.24, "Nuclear Criticality Safety"

DOE-STD-3007-93, "Guidelines for Preparing Criticality SafetyEvaluations at Department of Energy Non-reactor NuclearFacilities"

WHC-CM-4-29, "Nuclear Criticality Safety Manual," issuedSeptember 15, 1988.

Choice of Computer Models. The principal tool selected forcriticality calculations is the PC version of MCNP, Version 4A,developed and supported by the Los Alamos National Laboratory(LAND, Reference 2. This code was selected because of its greatflexibility, high fidelity modeling (e.g., ENDF/B-V continuouscross sections) , and the ability to perform both shielding andcriticality calculations.

Another code available for criticality calculations is KENO,Version V.A (contained in the SCALE-PC, Version 4.1; Reference 3) .This code was not used to perform criticality calculations directlyfor this study, but was used to compare results during thevalidation and verification process.

Code Verification & Validation. All codes used in shielding andcriticality calculations at Fluor Daniel have been verified byrunning the test problems supplied with the code packages. The

2-42


CSB Trade Study Fluor Daniel, inc.Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 ConCracC 04436306

test problem results are shown to be in agreement either with thepublished documentation supplied as part of the code package, orwith the sample problem output, if supplied. This information isdocumented, dated, and retained on file at Fluor Daniel. Anychanges, such as upgrades, corrections, modifications, etc., areincorporated into the documentation following rerunning of theverification problems.

MCNP, Version 4A is the latest version, Reference 2, of a widely-used and well accepted radiation transport code employed for a widevariety of radiation analyses including neutron, photon andelectron transport, and criticality. LANL has performed extensivecalculations with MCNP,. duplicating a wide ranije of experimentalresults, to validate the models contained in this code. Theresults of these benchmark cases are documented in References 4 and5. The version of MCNP4A used at Fluor Daniel was tested byexercising the twenty-five sample problems supplied by LANL, andthe results were found to be in agreement within reasonablestatistical limits. These sample problems are designed to exercisea broad range of the code's computational capabilities, includingcriticality calculations, which is addressed by five of the twenty-five sample problems.

Material Properties. The densities and composition of materialsused in the criticality calculations are given in Tables 2-6 and2-7.

Preliminary Calculations. Preliminary criticality calculations wereperformed to define the worst case spacing of fuel elements insidea canister, and/or each layer of a CSB storage tube. To this end,a computational model of seven storage tubes was formulated; with12 vertical layers, each layer consisting of 31 fuel elements in atriangular pitch array. The material composition of this arrayconsisted of fuel elements only: concentric cylinders of 1.25%enriched uranium, with zirconium cladding. All voids and spaceswithin the fuel elements and storage tubes were filled with water,and water was medium surrounding these storage tubes on all sides.The k.cf of the configuration was calculated, varying the pitch ofthe triangular array. The results are shown in Figure 2-19. Theimportant result of these calculations is that the worst casespacing between fuel elements is 3.2 inches.

The spacing between storage tubes, was 55 inches. These tubes wereagain arranged in a hexagonal pattern, in cross section, whichapproximated the storage tube configuration within the CSB vaults.Because of this spacing between tubes, and because the tubes wereimmersed in water, there was no appreciable interaction between thetubes, and the results show no sensitivity to variations in thisspacing (except when the tubes were placed very close together, asdiscussed below).

2.2.4.4 Results Of Calculations

A computational model was formulated which could address key-factors with respect to criticality safety for Concept 2D. Alluncertainties were compensated for with conservative assumptions.In the event these assumptions led to an unacceptable risk of acriticality event, it was planned to perform sensitivity studies toidentify safe limits.

In this computational model, fuel elements were arranged incolumns, each containing 280 fuel elements. Each column containedfuel arranged in patterns representative of two MCO's, stacked oneon top of the other. Each MCO was modeled with five verticallayers of canisters, two canisters of 28 fuel elements, per layer.The 28 fuel elements in each layer were arranged in a patternsimilar to that found in the canisters, Figure 2-20, but thecenter-to-center separation between fuel elements was taken to be3.2 inches, the worst-case spacing from Figure 2-19.

In a nominal CSB vault, 220 such columns would have been arrangedin a hexagonal pattern. This pattern was modeled as a triangularpitch array, with a 55 inch center-to-center separation betweencolumns, Figure 2-21. (Since interaction between columns isnegligible, this will be shown in what follows, changing the sizeof this array was not required.) The closest spacing betweencolumns, which could be achieved in a flooded pool, was assumed tobe 26 inches, center-to-center. This assumes a bare MCO, no tube,and a minimal amount of structural material for keeping the 24 inchOb MCO in place. For this calculation, no credit was taken foreither the MCO or the canister walls. In fact, the only materialsincluded in this model are the fuel, cladding, and the surroundingwater. The results for this configuration gave a k.ff of 0.81289with a standard deviation of 0.00091 (calculation ID: NF032).Replacing the water outside the MCO boundaries with air, gave a k.£fof 0.87063, +/- 0.00073 (NF033). This increase is probably due tothe increased interaction between columns for this close a spacing.

To evaluate the impact of some of the structural material, assumedto be stainless steel (SS 304) , the case with air outside the MCOwas repeated, but this time the canister walls were included in themodel. This calculation gave a k,ff of 0.77375, with a standarddeviation of 0.00065 (NF034) . Including the MCO wall material,further reduced the k,£f to 0.74524 +/-0.00069 (NF035) . (Toaccommodate the 3.2 inch spacing between fuel elements, thecanister outside diameter was taken to be 9.2 inches and itsthickness 0.25 inches, Figure 2-22. This should be compared to astandard schedule 20, 8 inch pipe which has an outside diameter of8.625 inches and the same thickness.)

Increasing the spacing between columns to 55 inches and includingthe tube material, reduced the k.ff to 0.7234 +/-0.00061 (NF036) .

The relatively small decrease between this case and case NF035,indicates that the interaction between columns has already beensignificantly reduced by the addition of the MCO wall material.

Case NF03S is representative of Concept 2D storage of MCO's in airfilled tubes with forced refrigerated air cooling of the tubes.Eliminating water from the calculation will result in an under-moderated situation with an effective decrease in k#ff. Filling thevault with water would have only a minor effect on the vault k#fC,since there is only negligible interaction between tubes at thisspacing and when taking credit for tube and MCO wall thicknesses.(The case of a water filled vault is a credible accident scenarioand would have to be considered in a criticalitysafety evaluation.Partial filling of the vault with water may actually be a worstcase situation, as was illustrated by comparing results for casesNF032 and NF033.)

2.2.5 Shielding

Shielding calculations during the feasibility study evaluationswere performed with MicroShield 4 which is adequate for the bulkshielding studies performed. The adequacy of this method wascalculated using the MCNP, Version 4A, code. Penetrations, ducts,and cracks were not evaluated but are noted where additional workwill be needed in the future. Some allowances were taken with thebulk shielding thicknesses in anticipation of the more complicatedgeometries.

Shielding issues associated with Concept 2D which were notaddressed in either the Feasibility Study or the Trade Study, butwhich may contribute to design changes, include the following:

• Tube Closure Design, Tube Spacing

Tube spacing in the vault may depend, in part, on the design ofthe tube closure at the operating floor level. Exposure levelsabove tube closures will depend on operating floor thickness andradiation streaming through gaps around the closures. Anypenetrations through these closures, for gas/liquid sampling, mayalso contribute to these exposure levels. The MCO's internalstructure may favor propagation in the axial directions,enhancing the radiation environment at the top and bottom of thetubes. (This will be particularly significant afterstabilization.)

• Unfinished Vault Capable of Future Outfitting

An unfinished vault presents several closure and shieldingproblems. Openings to both the intake and exhaust plenums willhave to be closed off both to reduce radiation in this vault andto restrict refrigerated air flow through the unused vault.

2-51


Ci3 Trace Stuc.y Fluor Dan:.e.\, Inc.We =c:.nghouse Kanford Company Government S«rv:.cesWKC P.O. TVW-SW-370252 Contract 0443(1306

Provisions must be made Co remove these barriers, under a highradiation environment, when this vault is eventually activated.

• Temporary Refrigerated Air System

The means of delivering refrigerated air to the vaults may-require additional ducting and wall penetrations. These ducts,and wall penetrations will have to be designed to preserve therequired low radiation exposure levels outside the building. Anyclosures to existing air intakes and exhausts will have to beremoved, under enhanced radiation conditions, when the switch ismade to passive cooling for stabilized fuel.


The shielding issues for Concept 2D involve health protection ofthe occupants of the SSF throughout its life. During the SSFFeasibility Study selection of an appropriate source term wasexamined by looking at the defined "limit" (maximum) source andanother "shield" (average) source, as well as a combination of thetwo sources. There are several water conditions that must be metat all times to provide a maximum dose rate of 0.2 mrem/hr. Theseinclude the minimum pool water depth over the filled MCO racks andthe minimum water level over an individual MCO. The interior andexterior wall thicknesses are important to provide healthprotection during possible construction activities. The operatingfloor thickness must protect workers during maintenance activities.The thickness of the transporter or shielded cask must provideadequate shielding during transport, insertion and removal of theshield plugs and MCO's.

2.2-. 5.2 Source Selection

Three possible sources were examined to determine the mostappropriate for the shielding studies. The "maximum" source isthat found in Section 2.8, Basis For Design, "Draft MCO Table" byR. G. Cowan, March 17, 1995. The "shield" source is that found inTable 3.6 - Safety Basis Radionuclides - referenced as the shieldsource in paragraph 3.6 - Shielding Design Basis of the "DraftDesign Basis Feed Development", A. L. Pajunen, December 22, 1994.Direction from Westinghouse indicated that the "maximum" sourceidentified with 10 canisters should be used. Previous experienceand the increased number of radionuclides in the "shield" sourceprompted examination of the two sources. The "shield" source isbased on the most radioactive fuel elements currently in the K-Basins. Apparently, there is only 0.6 metric tons of thismaterial, which is considerably less than one filled MCO. However,three cases were examined: 1) filled MCO with the "maximum"source; 2} filled MCO with the "average" source; and 3) combinedMCO with 0.6 metric tons of the "average" source and the balance ofthe fuel elements of the "maximum" source. A simple geometry of an

2-52



MCO immersed in water with a 2 foot concrete wall was used toevaluate the three sources. All other things being equal, exceptfor the radionuclide composition, the resulting dose rates were:"maximum" - 0.0112 mrem/hr; "average" - 0.0122 mrem/hr; and"combined" - 0.0114 mrem/hr. The limit source was selected sinceall sources were very close to being equal.

The impact on shielding requirements, of changing the MCOconfiguration to include five layers of canisters, instead of four,and changing the isotope mix to that specified as the "Maximum" MCO(Appendix 1) , was evaluated. This was done by generating a morerepresentative model of the MCO geometry for use in MCNP MonteCarlo simulations. Sample calculations were performed with thismodel, using a gamma source based on the "Maximum" MCO isotope mix.The results of these calculations confirmed that the conservativeapproach used to define shielding requirements based on the MCOsource model discussed above were adequate to accommodate theincreased source of the new MCO model. The changes in shieldingrequirements, recommended as part of this Trade Study, are based onthe lowered exposure level requirement for occupied areas (i.e.,lowered from 0.5 mrem/h to 0.2 mrem/h).

2.2.5.3 Minimum Water Depth Over a Single MCO

The MCO is brought into the SSF in a shielded cask. The cask isimmersed in water before withdrawing the MCO. Radiation shieldingof the MCO is provided by the water surrounding the cask and theMCO. Whenever the MCO is not in the cask, it must be surroundedand covered by water. Personnel do not generally have access tothe sides or bottom of the pool so only the top of the MCO must beshielded. This shielding is provided by establishing a minimumwater depth above the MCO which must be maintained. This minimumwater depth is 8 feet.

2.2.5.4 Minimum Concrete Thickness of Interior and Exterior Walls

There are several construction sequence possibilities for the SSF.The thickness of the interior walls is not important from a healthprotection standpoint if all construction is performed initially.However, if one vault is constructed first and filled and the otherstorage vaults are built at a later time, the construction workerswill need to be shielded against radiation penetrating the interiorwall between the filled vault and the adj acent vault. Anadditional need for personnel access to a vault could be forcleanup before conversion to natural convection cooling. If thiscleanup is required, all MCO's in the vault to be cleaned will needto be removed. Radiation levels from adjacent filled vaults willneed to be less than 0.2 mrem/hr to avoid partial emptying of theadjacent vaults. The minimum wall thickness required is 42 inchesof full density standard concrete. Since the interior walls arecurrently 36 inches of full density concrete, the wall thickness is

2-53


Westingrouse Kanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

leas than adequate for maintenance activities near the wall. Atone time, there was an additional layer of thermal concrete (lowdensity) applied to the interior surfaces of the vaults. If thisadditional thermal layer is included in the SSF design, theshielding may be adequate. Also, since entry into the vault willonly occur if cleanup is required, localized shielding might be abetter solution than increasing the wall thickness.

An unfinished vault presents several shielding problems, inaddition to the inside wall thickness requirements. Openings toboth the intake and exhaust plenums will have to be closed off withshielding materials to reduce radiation exposure levels in thisvault during any future reconfiguration. Provisions must be madeto remove these shields, under a high radiation environment, whenthis vault is eventually activated.

The second construction sequence involves the construction of theStabilization Facility adjacent to the exhaust plenum. Excavationcould remove all of the soil surrounding the exterior wall. Again,the minimum wall thickness is 42 inches, so that the 54 inchexterior wall is more than adequate.

2.2.5.5 Minimum Thickness of Operating Floor

Radiation protection of personnel from stabilized MCO's in drystorage is provided by the concrete operating floor. This floor,along with the individual shield plugs which provide access intoeach storage tube, must provide shielding sufficient to maintain atarget dose rate of 0.2 mrem/hr. The minimum floor thickness mustbe 48 inches. This floor thickness allows for a solid floor. Whenthe floor is cast with plug holes and the holes are fitted withplugs which do not completely fill the space, radiation streamingis possible. Plugs and holes with steps solve this problem. It isestimated that the current design thickness of the floor is 60inches which will provide adequate shielding. The geometry withthe holes and plugs will need to be examined thoroughly at a laterdate.

2.2.5.6 Minimum Transporter/Cask Thickness of Steel and Tungsten

There are two options for transporting the MCO's filled withstabilized fuel tubes. The first would involve a stand alonetransporter which would be driven around on the operating floor.The second would involve a special remote controlled cask whichwould be moved with an overhead crane. In either case, personnelhealth protection and shielding weight are important. The targetcontact dose rate is 0.2 mrem/hr. The thickness of iron to achievethis dose rate is 14 inches. The thickness of tungsten to achievethis dose rate is 4.7 inches. The tungsten shield is moreexpensive, but considerably lighter which reduces the cost of thetransporter or overhead crane. These thicknesses provide gamma

CS3 Trace otuc.y Fluor uaniex, m e ,West-ngrouse Fanford Company Government ServicesWHO P.O. TVW-SW-370252 Contract 04436306

shielding only. These shielding requirements will need to bereviewed for neutron shielding adequacy (Section 2.2.5.8)

2.2.5.. 7 Special Shielding Issues (Neutrons, Betas)

A neutron source was not provided and neutrons have been ignoredduring this study. However, in future design efforts, neutron doserates will need to be evaluated. The areas of particular concernare the incoming and outgoing casks and the transporter/cask.These shielding structures are designed to provide adequate gammashielding. Additional neutron shielding may be needed. Theneutron source will result from some a,n reactions and spontaneousfission of the transuranics.

The beta source does not appear to be a significant shieldingsource in the MCO. The shielding concern is not to provide betashielding which is provided by the shell of the MCO, but to provideadequate shielding of the Bremsstrahlung radiation resulting fromthe beta absorption in the gamma shield.

The secondary photon source, resulting from the "Maximum"MCO (Section 2.8) mix of beta emitting isotopes, was evaluated usingMCNP. This source of photons was found to contribute less than 3%of the exposure rate contributed by the gammas.

2.2.6 Conversion

Conversion of Concept 2D from refrigerated air cooling ofunstabilized fuel to passive dry storage will be accomplished afterstabilization of all the MCOs is complete. As MCOs are removed forstabilization, MCOs containing dry stabilized fuel will beinstalled in dry storage tubes upon return from the StabilizationFacility. When all of the fuel has been stabilized and higher fueland vault temperatures can be tolerated, blinds in the air intakeplenums and stack would be removed, air refrigeration equipmentwould be shut down and isolated if necessary, allowing naturalcirculation cooling to be established.

There do not appear to be any additional feasibility issuesassociated with the conversion from refrigerated air cooling topassive dry storage for this concept other than shielding andradiation safety, already addressed.

2.2.7 Health Physics

2.2.7.1 Objective

2.2.7 . 2 Summary

Whereas? the facility as designed for the Hanford WasteVitrification Plant (HWVP) project is ideally suited for thestorage of spent fuel, there are some features of concept 2D thatwill need to be altered in order to meet the latest DOErequirements such as DOE/EH-0256T, Radiological Control Manual,Rev. 1, April 1994. For example, the facility will require changerooms, step-off-pads (SOP) , and a personnel decontaminationfacility. In addition, the concept of allowing the third vault toremain empty will not work from an HP or an HVAC stand pointwithout major changes to the building. The building modificationswill more than likely off-set any potential savings attributable todeferring the third vault work at this time. Although dataconcerning the potential neutron source associated with the max Amulti-canister overpack (MCO) shielding source is not available atthis time, it is inevitable that there will be more neutronsassociated with this source than there were with the HWVP sourcebecause this source contains far more fissile material. Further,since a neutron shield was required on the HWVP transporter, beadvised that it will be required as an integral part of theshipping cask and as part of the floor plug shield valve. Finally,it is beyond the scope of this study and left to later designstages to verify that workers will be able to remain on theoperating floor during insertion of the MCO into the storage tubes.

2.2.7.3 Facility Description And Evaluation

It should be noted that although the CSB was designed when theyearly exposure for radiation workers was 1,000 rnrem cumulativetotal effective dose equivalent (CTEDE), the Westinghouse HanfordCorporation (WHO and the Fluor Daniel Inc. (FDD, Health Physicsdepartments mutually agreed that this dose should be divided into400 mrem/yr, whole body dose, and 600 mrem/yr for internal doseexposure. The DOE regulation cited above, limits the yearly CTEDEto radiation workers to 500 mrem. This means that the CSB isdesigned in compliance with Che latest contemporary DOEregulations. The design of the operating floor meets the latestWHC requirements for a radiation access zone (RAZ) 1 which permits40 hours per week occupation.The Radiological Control Manual (Rad Con) manual requires the HPfacilities noted above in the summary. In addition, the SOPs mustbe contiguous with the radiological areas that require radiationwork permit (RWP) /special work permit (SWP) such as the caskhandling, storage, preparation and operating areas.

If the third vault remains empty, without any flow restrictions,then the preponderance of natural convection air, afterstabilization, will flow through Che empty vault and not throughthe MCO filled vaults. Flow restrictors will be difficult, if notimpossible, to remove if WHC finds a use for the vault at a later

date because it is currently inconceivable that anyone can enterthe area after the first and second vaults are filled with MCOs.Please be advised that even if the wall thickness between thesecond and third vault is increased, the scattering around theexhaust and inlet plenums will most likely produce a RAZ 5, whichdoes not allow access.

The shipping cask and the floor plug stiield valve will have toprovide shielding against gammas, beta originated bremsstrahlungradiation (X-rays) and neutrons. The preliminary estimates withoutbremsstrahlung or neutrons, indicate that the maximum MCO willproduce a dose rate of approximately 200 R/h at three feet from themidsection of the overpack. It should be noted* that the shieldingrequirement to allow this source to become contact maintained in aRAZ 1 would be approximately 14 inches of steel. This shield mayexceed the weight restrictions for the CSB floor and crane. Thisis one of the reasons why it may not be possible to allow workersto remain on the operating floor during insertion of the MCO intothe storage tubes.

2.3.0 SAFETY ANALYSIS

2.3.1 APPLICABLE REQUIREMENTS

The environmental, safety and health (ES&H) requirements applicableto the SSF are very similar to the requirements applied to the HWVPCSB, especially for the storage phase- Other than updatedrequirements for protection against natural phenomena (recentlyissued DOE-STD-1020) , all such requirements applicable to the CSBwill apply to the SSF.

The CSB design (the starting point for the SSF design) wascompleted using these ES&H requirements as part of the designbasis. This CSB design has been reviewed and approved by the DOE,WHC and the State of Washington as meeting all these requirements.This successful track record should ease the regulatory process forthe SSF.

On the other hand, the fact that spent nuclear fuel (SNF) is beingstored instead of glass, and the necessity for wet storage ofunstabilized fuel in the staging phase, will make several newadditional requirements applicable to the SSF. For example, inaddition to meeting the requirements applicable to the CSB, WHC hasindicated that the SSF will be required to meet the intent ofNuclear Regulatory Commission requirements for SNF storagefacilities.

This section documents the results of a first-cut Design BasisAccident (DBA) analysis for the SSF. It describes the

2-61



pre-conceptual safety design basis of SSF Feasibility DesignConcept 2D, including the basis for determination of requiredSafety Class (SO SSCs.

A spectrum of candidate accident scenarios is postulated. Includedare scenarios required to be addressed by programmatic requirementsand additional scenarios identified by the WHC Draft PreliminaryHazards Analysis (PHA). All postulated scenarios are addressed.

The radiological consequences for each DBA are calculated for SSFFeasibility Design Concept 2D. The SSF is located on the site ofthe HWVP CSB (20,000 meter site boundary distance).

These consequences are compared with the onsite and offsiteradiological dose limits of WHC-CM-4-46, Section 9.0 (Revision OB) .Where unmitigated consequences exceed the dose limits, mitigatingSSCs are designated as SC-2 or SC-1 as appropriate. Credit istaken for the operability of these SSCs to mitigate theconsequences of the DBA to within the dose limit.

These frequency-dependent dose limits include the following:

A. Offsite:

1. Accident frequency of >lE-2 to alE-l/year: 0.5 rem

2. Accident frequency of >lE-4 to slE-2/year: 5 rem

3. Accident frequency of >lE-6 to slE-4/year:25 rem

B. Onsite:

1. Accident frequency of >lE-2 to alE-l/year: 5 rem

2. Accident frequency of >lE-4 to slE-2/year: 25 rem

3. Accident frequency of >lE-6 to slE-4/year:100 rem

2.3.2.1 DBA Methodology

2.3.2.1.1 Event Consequences

The methodology described in DOE-STD-1027-92 is used for thisanalysis. The following equation, from page A-6 ofDOE-STD-1027-92, describes the basic method used to calculate theoffsite dose for each DBA:

MOI Dose= (MAR) (RF) (X/Q) (RR) (SA) (CEDE)(1)

or:(Source Activity) (CEDE) (RF) (X/Q) (RR)(la)

2-62

UHC-SD-W379-ES-Q03 Rev. 0


where:

MOI Dose - Maximum Off sice Individual Dose[rem]

MAR - Material at Risk [grams] ; RF - Release Fraction [Unitless]

RR - Respiration Rate [m3/sec]; SA - Specific Activity Cci/g]

X/Q - Atmospheric dispersion factor for the [sec/m3]site boundary distance

CEDE - Committed Effective Dose Equivalent [rem/ci]per curie inhaled

Source Activity ~ (MAR) (SA) [ci]

2.3.2.1.2 Initiating Event Frequencies

Formal quantitative calculation of event frequencies is notincluded in this assessment. The estimated frequencies listed inResults Table A are based on the frequency categories shown in theWHC Draft PHA.

As stated in the assumptions below, the frequencies of severalscenarios are assumed to be below the threshold of credibility,based on the assumed outcomes of future, more detailed safetyanalyses. These assumptions should be verified or changed in laterphases of the design of the SSF, based on the results of theseanalyses.

2.3.2.1.3 Scenario Development/Screening

The first step in the DBA analysis process is a screening processto justify eliminating from consideration all scenarios that arenot DBAs. Remaining as DBAs are those scenarios that meet both ofthe following criteria:

A. The scenario is "credible:" The frequency of occurrence of theinitiating event is equal to or greater than lE-6/year. Accidentswith frequencies less than this threshold are considered to be"beyond the design basis," or "not credible." This credibilitythreshold is defined in Section 1300-1.4.2 (and the Glossary) ofDOE Order 6430.LA. The basic credibility threshold of lE-6/year ismodified by DOE-STD-1021 for natural phenomena hazards (NPH) tolE-5/year. Accidents beyond the design basis, or "residual risk,"will be analyzed in later phases of the design as required by DOEOrder 5480.23.

B. The scenario is the limiting, or highest consequence, accidentin its type: For example, the (credible) spill with the mostsevere consequence is the "design basis spill." If the plant is

2-63


CSB Trade Study Fluor Daniel , I nc .Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

designed to mitigate the risk of the design basis spill to withinthe dose limits, then it also can mitigate adequately all spills oflesser consequence.

2.3.2.1.4 Material At Risk Estimates

All spent fuel received at the SSF will be contained in SafetyClass Multi-Canister Overpacks (MCOs). For the purposes of thisassessment, Material At Risk (MAR) is assumed to be the "maximum"inventory of radionuclides in each MCO, taken from the "MCODescription" contained in Section 2.8, times the number of MCOs atrisk in each accident scenario. The one exception to this is the"uncontrolled gas discharge" DBA, where the MAR is assumed to bethe Kr-85 inventory of one MCO.

Failure of a MCO containing the "maximum" radionuclide inventorywould cause a release and a resultant dose that can be calculated.The theoretical inhalation dose that would result from uptake ofthe entire contents of a MCO (immersion dose for Kr-85) iscalculated. This doses is the "peak inhalation Committed EffectiveDose Equivalent (CEDE) at the source." The method of calculationof this dose source term is described below.

2.3.2.1.5 Source Terms

Equation (la) shown in the Methodology section above can berestated as follows:

MOI Dose = [ (Source Activity [in curies]) (CEDE)] [ (RF) (X/Q)

(RR)]

or • =[Inhalation CEDE at the source] [K]

where:[Inhalation CEDE = (Source Activity) (CEDE) (2)at the Source]

and K« (RF) (X/Q) (RR)

The "K" part the dose calculation is independent of the nuclearcharacteristics of the source MAR. Inhalation CEDE At the Source,on the other hand, is completely characteristic of the each nuclidemaking up the source term.

In fact, the RF (1E-3 for all isotopes except Kr-85) and RR (3.5E-4m3/sec) and meteorology all are assumed to be fixed for the SSF byDOE-STD-1027-92. The CSB site boundary distance (20,000 meters)fixes X/Q for the SSF as well, as described below.

2-64



Equation 1 is intended to be used to calculate the dose caused by-one source radionuclide at a time. The inventory of a MCOcomprises several isotopes as listed given in the Appendix l "MCODescription".

The dose that would result from a failed MCO containing thismixture of isotopes actually would comprise the sum of theindividual doses contributed by each isotope present in the mixtureat the time of release:

(Inhalation CEDE=£ (Source Activity)L (CEDE)iof the mixture) L

The (Source Activity) L values used in this analysis are taken fromthe Section 2.8 "MCO Proposed Description". The CEDEj. values aretaken from DOE/EH--0070 and DOE/EH--0071.

2.3.2.1.6 Release Modeling

As stated above, the release model used for this analysis is takenfrom DOE-STD-1027-92. The Release Fraction (RF) used for eachscenario is 1E-3(except for noble gases such as Kr-85, which havean RF of 1). Respiration rate (RR) of the receptor used for eachscenario is 3.5E-4 m3/sec. Both are bounding values taken fromDOE-STD-1027-92, page A-7.

The offsite receptor distance for the HWVP CSB is 20,000 meters.The onsite receptor distance is 300 meters per DOE-STD-1027-92,page A-7.

Atmospheric dispersion factors (X/Q values) are derived for theoffsite and onsite receptor distances using the meteorologicalassumptions recommended for Preliminary Hazard Analyses inAppendix A (p. A-7) of DOE-STD-1027-92:

D-stability weather classification

4.5 meters/second wind speed

These parameters are used with the appropriate distances as inputsto the GENII algorithm, documented in PNL-6584, to calculate thefollowing X/Qs:

A. Maximum Offsite Individual(MOD (20,000 meter Offsite Boundary) :3 .206E-7

B. Onsite receptor (300 meters):2.200E-4

These values are significantly less conservative than the X/Qs usedfor the HWVP CSB accident analyses. At the high end of the rangefor X/Q is the conservative X/Q used for the HWVP CSB PSAR

2-65


CS3 Trade Study Fluor Daniel, Inc.westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

Addendum, the "0-8 hour release" site boundary X/Q, 8.67E-6. Thisis greater than the DOE-STD-1027 off site X/Q by a factor ofapproximately twenty seven. This wide range of X/Qs that arepotentially applicable to the SSF is used to calculate the "range"of doses reported in Results Table 2-8 below.

2.3.2.2 Assumptions

2.3.2.2.1 Initiating Event Frequency/Credibility

A. Except for the "MCO failure" DBA, fire anywhere within the SSFis not a credible initiating event. Similarly, fire as a dependentevent (e.g., caused by a DBE) is not a credible event. The basisfor these assumptions is qualitative at this early phase of thedesign. The Fire Hazards Analysis (FHA) has not been performed.For several reasons, however, there is a level of confidence thatthe FHA will result in a detailed facility configuration thatpositively will prevent the introduction of significantcombustibles into the facility and support this assumption.

Historically, SNF storage facilities such as the SSF have posed asubstantially lower fire risk than other types of facilities suchas reactors and radiochemical processing plants. Normalcombustible loadings are at insignificant levels throughout most ofthe SSF. Review of chemical usage in the facility generally showsminimal use of combustible chemicals.

Process engineering has reviewed the rates and amounts of hydrogenreleases from MCOs during normal operation. At the rate ofonce-through ventilation planned for the operating deck, hydrogenconcentrations will stay several orders of magnitude belowflammable limits. Even after an extended loss of ventilation {notconsidered credible) it would take several days for concentrationsto reach flammable levels. This could be prevented merely byopening exterior doors to the wind.

For Concept 2D, periodic purging of the tube annulus during normaloperation will prevent the buildup of hydrogen to dangerous levels.Even if hydrogen levels did reach flammable levels in the annulus,there is no ignition source in the tube.

There are, however, a few issues identified to date that could bearon the validity of this assumption and should be addressed indetail by the FHA:

i. The capability should be provided for an adequate, timelyresponse to a possible fire resulting from the failure of a MCO,resulting from a handling drop or other leakage of water from a MCOand ignition of the uncovered fuel rods.

2-66



ii. If diesel generators and/or batteries are used for backupelectrical power, then the fire risk associated with this equipmentshould be addressed.

iii. Although it is a relatively smaller risk, the fire riskassociated with the use of ion exchange resins, filter media andregenerant chemicals should be addressed.

iv. The FHA should consider the fire risks associated with anyuse of liquid nitrogen inside the SSF, such as the condensation andreevaporation of oxygen from the surrounding atmosphere.

This assumption is key to this assessment. If it were invalid (ifa substantial release due to a fire (not related to a MCO failure)were credible inside the SSF, then SC mitigation may be required tomeet the dose limits. Substantial additional SC SSCs could berequired. This change could affect the estimated capital cost ofthe facility significantly.

B. Explosion anywhere within the vicinity of the SSF structure(including the stacks) is not a credible initiating event.Similarly, explosion as a dependent event (e.g., caused by a DBE)is not a credible event. The basis for these assumptions also isqualitative at this early phase of the design, because the FireHazards Analysis (FHA) has not been performed. For reasons similarto those listed above for fire, however, there is a level ofconfidence that the FHA will result in a detailed plantconfiguration that positively will prevent the creation of acredible explosive hazard in the vicinity of the SSF and supportthis assumption.

There are, however, a few issues identified to date that could bearon the validity of this assumption and should be addressed indetail by the FHA:

i. If hydrogen gas or other explosive gases or liquids would beused in the facility, the source containers preferably should belocated outside the SSF, far enough away so that leakage andexplosion involving all the stored gas would not be a crediblethreat to the SSF structures.

ii. If any such gases are brought into the facility viapermanently installed tubing, then the tubing from the storagebottle should be provided with Safety Class isolation valves.These valves must close automatically on high seismic acceleration.

iii. If a bottles of such gases are transported into (thevicinity of) SSF structures, then the frequency and consequences ofthe resultant hazard should be limited:

2-67



a) The capacity of the bottles should t>e minimized, and

b) The amount of time the bottle is in the facility should beminimized.

The FHA should show that an explosion capable of failing SafetyClass SSF structures is not a credible event.

This assumption also is key to this assessment. If it were invalid(if an explosion capable of threatening failure of SSF structureswere credible) , then SC mitigation and/or structural upgrades couldbe required to meet the dose limits. Substantial additional orupgraded SC SSCs could be required. This change could also affectthe estimated capital cost significantly.

C. Analysis of aircraft crash, both credibility (frequency) andconsequences, is not included in this assessment (i.e., forpurposes of this assessment, aircraft crash is assumed notcredible). The extensive analysis already done for the HWVP PSARproves that this is the case.

D. This analysis assumes that a MCO will fail (release itsradioactive contents) if dropped from a significant height, both inand out of water, whether or not it is inside a MCO handling cask.In contrast, it is assumed that the transport cask (and the MCOinside it) will not fail if dropped from any height attainable inthe facility, unless the lid is unbolted- If the lid is unboltedwhen the cask is dropped, then it is assumed that the impact ejectsthe MCO from the transport cask and causes the MCO to fail.

Similarly, it is assumed that an uncontrolled discharge of gas froman MCO (due to a relief valve sticking open or a hydrogen burninside the MCO) results in the release of the entire maximuminventory of Kr-85 from the MCO, This is considered to be a veryconservative assumption that is a candidate for relaxation ifnecessary, by more detailed analysis in later phases of the design.

2.3.2.2.2 Event Consequences

A. Loss of ventilation due to equipment failure or power failureis not considered to be a DBA initiating event because it causes norelease by itself, and requires no mitigation by permanentlyinstalled SSCs. In later stages of the design, the effects ofthese and other equipment failures will be considered in the designof SC SSCs, when taken as single failures in addition to DBAinitiating events, as required to meet the single failure criterionof DOE Order 6430.1A, WHC-CM-4-46(MRP 5-46) and IEEE 379.

B. It is assumed that SSF SC SSCs will be designed to withstandthe effects of the site-specific Design Basis Earthquake (DBE),Design Basis Wind (DBW), and Design Basis Ashfall and other natural

2-68

phenomena hazards without causing an offsite dose exceeding thelimit, as required by DOE-STD-1021-92, Reference L. Thisassumption is reflected in the capital cost estimates herein.

C. It is assumed that only one MCO or cask will be moved at a timeduring any loading, unloading, servicing or inspection activity.

D. HVAC calculations show that approximately 20 hours after forcedair cooling is lost, the temperature in the tubes has risen only30 °F. Concept 2D is currently not a safety class system.Adequate time would most likely not be available after a loss ofcooling or loss of power event to bring in mobile emergency coolingcapability well before temperatures reach unacceptable levels.Based on this assumption, no permanently installed emergencycooling or makeup system is included in the SSF Feasibility Design,in accordance with Section 1320-4 of DOE Order 6430.1A.

2.3.2.3 Results

2.3.2.3.1 Scenario Screening Results

Table 2-8 shows the results of the scenario screening process usedto determine which scenarios are considered DBAs applicable to eachphase of SSF Concept 2D.

2.3.2.3.2 Material At Risk/Source Terms

Table 2-8 also shows the MAR quantities/source terms for each DBA.

2.3.2.3.3 Unmitigated Doses/Facility Hazard Category

Table 2-8 also shows the unmitigated offsite and onsite doseconsequences for each DBA. Dose consequences are compared with theonsite and offsite dose limits of Section 2.3.2 above.

As Table 2-3 clearly shows, the total quantity of MAR present inthe SSF makes the facility a candidate for DOE Hazard Category 1(High Hazard) , the same category as the K-Basins (and the HWVPCSB) .

2'. 3.2.3.4 Safety Classifications

Where unmitigated offsite consequences exceed the applicable doselimit, credit must be taken for the operability of DOE Safety Class(WHC SC-1) SSCs to prevent or mitigate the consequences of the DBAto within the limit. When credit is taken for the SC-1 SCCs shownin Table 2-8, offsite consequences are less than the dose limitsfor all eight DBAs analyzed, given the Assumptions on which theanalysis is based.

Similarly, onsite consequences are less than the onsite limits for

2-69


wo.? ..race snuc.y Fluor uaniei, inc.We:Et;.nct.ouse Kanford Company Governmenc ServicesWHC P.O. TVW-SW-370252 Contract 04436306

most DBAs analyzed, again given the assumptions on which theanalysis is based. The exceptions are DBA Nos. 2, 3 and 4, MCOfailure scenarios. For these accidents, the particulate releasescan be filtered by the emergency ventilation exhaust system to asmall fraction of the threshold. Along with the particulate,however, the maximum MCO inventory of Kr-85, an unfilterable noblegas, is released.

Calculations show that release of the Kr-85 inventory only from asingle MCO may exceed the onsite limits, depending on the X/Q used.If the X/Qs used for the HWVP PSAR are used (resulting in up to 720rem) , the limit would be exceeded. This issue probably can beresolved by more detailed analysis in later pha'ses of the design-Tables 2-8, 2-9 and 2-10 show the SC-2 and SC-1 SSCs required forthe SSF design to meet the onsite and offsite dose limits.

Structures/Performance Categories. Because the SSF is a candidatefor DOE Hazard Category 1, and because some of the structureslisted in Table 2-9 and 2-10 provide DOE Safety Class (WHC SC-1)protection against natural phenomena hazards, these structures arecandidates for designation as Performance Category 3 as defined inDOE Order 5480.28, and DOE-STD-1021.

Other structures listed in Tables 2-9 and 2-10 provide WHC SC-2protection against natural phenomena hazards. These structures arePerformance Category 2 as defined in DOE Order 5480.28, andDOE-STD-1021.

Systems. As Tables 2-9 and 2-10 show, there are nonon-structure-related DOE Safety Class (WHC SC-1) systems requiredfor'the SSF (except the MCO pressure boundary itself, which is notpart of the SSF scope) . These tables also show the WHC SC-2systems required for each SSF phase.

2.4 COST ESTIMATES

2.4.1 ESTIMATE BASIS

The capital cost estimates of the Concept 2D SSF configuration wasprepared as a Rough Order of Magnitude (ROM) estimate, utilizing acombination of estimating methodologies. The excavation estimatefor the vault/plenum area is shown at zero cost. The excavationwas performed by the C200-01 construction package contractor, HWVPProject. The estimate for the existing slab constructed by DavidMowat Company, (C350-01 construction package contractor) , is shownat zero cost. Unit rates for the construction of the below gradeportion of the SSF Facility, including the fabrication andinstallation of the storage tubes, were obtained from the HWVP CSBC350-01 package fair cost estimate. Unit rates for the above grade

portion of the facility were obtained from the Independent CostEstimate (ICE) prepared by the architect engineer in October, 1992,as part of the HWVP review of Key Decision (K-D) 3B. Quantities ofstructural steel were developed by Engineering. The Mechanical andProcess equipment requirements were obtained from the EquipmentList. Equipment installation and associated bulk material costswere factored from the equipment, which was priced in-house.

Miscellaneous site support costs were derived from quantity take-off estimates. Estimates for engineering construction, and projectmanagement, are expressed as percentages of direct construction andGFE procurement costs.

2.4.1.1 Assumptions

• All direct costs are expressed in present day (1995) dollars.

• The estimate was based on a standard 40 hour work week.

• Sufficient skilled labor is available on site during theperiod of construction.

• No project mission changes or major rework will occur duringthe engineering and construction of the facility.

• No radioactive or otherwise contaminated soil, or undergroundobstructions,will be encountered during excavation for thefacility.

• An est imated average craf t wage rate of $31.50/hour wasapplied to the estimated direct construction manhours. The

• average rate is based on the current Hanford Sitestabilization agreement, and current Hanford Site prevailingwages. The estimated rate covers the craft's base wage, plusbenefits and state legislated burdens.

• Engineering Costs:

25% of the direct construction cost estimates of the MCOLoading/Storage, Pool Water Treatment and InfrastructureAreas, including the Refrigeration HVAC Bldg. was added to12.5% of the Direct Construction Cost Estimate of the vaultsand office areas to provide an estimate of the Conceptual /Advanced Conceptual and Detail Design costs. Conceptual /Advanced Conceptual Design was assumed to be 20% of theengineering cost estimate, and detail design was assumed to be80%.

• The Title III engineering estimate was calculated at 4.0% ofthe direct construction cost estimate.

The estimated contingency was developed from an evaluation of thecompleteness of design information available to estimating, and thereliability of unit cost data obtained from prior estimates. Thefollowing contingencies were applied to the direct procurement,construction, and indirect cost centers of the estimate:

The resulting composite contingency is 17%.

2.4.2 CONCEPT 2D CAPITAL COST

The following capital cost alternative is included in support ofConcept 2D, 3 vaults, one empty, processed material stored in 440(2 vaults) dry Corten tubes.

2.4.2.1 Concept 2D Cost Estimate

Tables 2-11 and 2-12 contain the estimated capital cost and cashflow requirements for Alternative 2D, respectively. Supportingdetail is contained in Tables 2-13 and 2-14.

2.4.3 SIGNIFICANT OPERATING COST DIFFERENCES

Review of the operating costs indicated that Concept 2D may havehigher operating costs than other concepts i.e. a staging pool.The following operating cost factors were considered in reachingthis conclusion:

2.4.3.1 Operating Labor During Staging

The loading of MCOs into tubes is more labor-intensive than otherloading methods such as a pool rack. The distances that a poolcrane would have to travel are shorter than for tube storage.Placing MCOs in tubes requires many more operating steps, becausethe floor plug, floor plug handling flask, bottom-loading cask, andimpact absorbers have to be handled in addition to the MCO. A taskanalysis of tube loading shows that 4 operators would be requiredduring the loading, while 2 operators would be required for loading

2-79


WesCinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 ConCraci 0443(5306

pool racks. At the design rate of 4 MCOs per day, the loading willrequire 300 days. Unloading at the end of staging will requireanother 300 days. At the current estimated wage plus burdens andoverheads rate of $34.50 per hour, plus 15% average shiftdifferential, the Concept 2D labor cost is estimated at $1,140,000more (in present dollars) for loading and unloading.

In Concept 2D during staging, the tubes must be vented and purgedat the rate of at least 78 per day to prevent hydrogen frombuilding up in the tubes. If 375 tubes were filled and if 440tubes were used, 92 tubes per day would require purging (seeSection 2.2.3.2); if one were to use Los Alamos Tech Associates(LATA) data, 130 per day would require purging* for 375 tubes and150 per day for 440 tubes; pool concepts would not require thisactivity. From an estimate of 2 operators working regular days,the Concept 2D labor cost is $144,000 more per year of staging.Based on 7 years of staging, the Concept 2D labor cost is$1,000,000 more {in present dollars) for venting and purging, withthe cost increasing for each year of staging.

Combining the above labor costs without escalation, the Concept 2Dlabor cost differential (above a pool concept) will be $2,150,000plus $144,000 per year for each year that staging extends beyondthe assumed staging period of 7 years.

2.4.3.2 Fuel Cooling During Staging

Regardless of the concept used, heat load from the MCOs is thesame. However, a pool cooling concept would be more efficient thanair cooling, and the heat gain from surroundings would be less forthe pool. As a result, the horsepower ratings for the chillers andpool recirculation pumps in a pool concept would be about 500 kWless than for the chillers and air handling fans in Concept 2D. Atthe Bonneville Power wholesale rate of 30 mills per kW-hr, Concept2D costs about $13,000 per year more for power.

2.4.3.3 Heating, Ventilation, and Lighting

Because the buildings have about the same size and requirementsregardless of concept, there is no significant difference.

2.4.3.4 Crane Usage

In a pool concept the crane would be smaller than the storage cranein Concept 2D. In addition, the storage crane has to travelfarther with each MCO and perform more operations. The differencein power consumption averages about 50 kW, and is balanced by thedifference below due to water sterilization. This difference isnot significant.

2.4.3.5 Pool Water Sterilization

In a pool concept, the ultraviolet lamps for the sterilizers willconsume less than 50 kW of power, which is not significant, and isbalanced by the difference above due to cranes.

2.4.3.6 Chemical Consumption

The nitrogen consumption for MCO servicing and the decontaminationchemical consumption are the same regardless of concept. Becausepool water deionizers would not require regeneration as watertreatment chemical usage is not significant.

2.5 SCHEDULES

2.5.1 SCHEDULE ASSUMPTIONS

2.5.1.1 General

These schedules are based on the use of the Canister StorageBuilding (CSB) design and partially completed construction from theHanford Waste Vitrification Plant (HWVP) Project. Utility tie-insare available from the completed construction of the HWVP project.

WHC provided the date for start of the engineering studies, the KeyDecision 0 date of 10 March 1995, and the date of May 9, 1995 forapproval by DOE of the Functions and Requirements (F&Rs) for theproject. April 24, 1995 is assumed to be the start of ConceptualDesign and Capital funds are assumed to be available in October1995. The Stabilization Facility is assumed to be operational inDecember 2002.

This schedule assumes that there will be no annual fundingconstraints for the duration of the project.

The cost estimates prepared for each alternative provide a basisfor each schedule.

An important objective of these schedules was to have the SSFoperational and ready to receive MCO's from the K-Basins as rapidlyas possible. Aggressive, but achievable schedules were thereforedeveloped.

2.5.1.1.1 Engineering and Design

Maximum use of the existing engineering and design of the CSB andthe results of this feasibility study allows the approximatelythree month duration for conceptual design. New requirements andadditional facilities will have minimal impact to the existingfacility design and drawings.

2-85


We:3t;.nc'h.ouse Hanford Company Government ServicesWHO P.O. TVW-SW-370252 Contract 04436306

Client, review changes will have no impact at the end of conceptualengineering and definitive design. Continuous reviews andalignments are required to minimize change.

2.5.1.1.2 Procurement and Construction:

The October 1992 statused Mowat schedule for the CSB was used as abasis for deriving activity durations for completion of the walls,the operating floor and storage tube installation.

The construction of the facility will be performed with specialtysubcontractors.

There is no shortage of local craft labor or specialty contractorsin the area.

Construction is based on a standard forty hour work week.Scheduled overtime is excluded from this schedule.

The concrete slab and walls that are currently in place will beused with minimal changes required to complete the concrete vaultwalls and operating floor.

The walls for all vaults will be formed and poured simultaneously.

Rebar for the walls and for the operating floors will be pre-assembled and set in place with cranes.

Structural steel buildings will be prefabricated in shops, andassembled in the field.

Thete is no shortage of material locally, including concrete batchplant requirements.

Long lead equipment items will be identified very early so as tonot delay construction.

There are no shortages of construction equipment in the area.

Reviews by WHC will be concurrent with the design during all phaseswith a twenty day review continuing after the end of conceptualdes ign.

DOE reviews will be for twenty days after the WHC review period.

Independent cost verifications will be for twenty days after theWHC review and concurrent with the DOE reviews.

ESAAB reviews will take place for twenty-five days subsequent tothe DOE reviews and prior to Key decisions one through four.

Safety analysis reports will be generated on a one step SAR basis.Final review and approval extends for a nine month period andapproval is required prior to start-up. Construction will beallowed to commence based on approval of a preliminary safetyevaluation.

2.5.1.4 Concept 2D

Construction of the operating decks will be concurrent in all threevaults.

Storage tube installation will be concurrent in two vaults.

2.5.2 CONCEPT 2D SCHEDULE

Figure 2-24 contains the schedule for Concept 2D. It shows that,subject to the above assumptions, it is possible to achieveoperation of the SSF in December 1997. The entire facility isconstructed initially under this concept so there is no secondphase of procurement and construction.

2.6 CONCLUSIONS AND RECOMMENDATIONS

2.6.1 FEASIBILITY OF CSB ADAPTATION

The results of this study demonstrate that it is currently notfeasible to adapt the design of the CSB to meet the F&Rs of the SSFdue to the 100 °F MCO temperature requirement. If a relaxation ofthe temperature requirement was to occur then construction of theSSF on the CSB site will enable the. already completed CSB siteclearing and grubbing, site preparation, excavation, base mat andwalls to be utilized for the SSF, saving both time and money. Useof the CSB site for the SSF is also consistent with master planscurrently being developed for the Hanford Site and the objective ofmoving the N-Reactor fuel away from the Columbia River.

2.6.2 OTHER TECHNICAL CONCERNS

Relaxation of the 100 °F maximum MCO temperature requirement priorto stabilization would allow further cost reduction alternatives tobe considered.

In addition to a relaxation of the MCO Temperature requirementseveral other technical issues would require further investigationto ensure cost, schedule and safety requirements are achievedincluding:

• Shielding requirements regarding the empty vault and itsfuture use.

• Contact maintenance and servicing of the transport andfacility casks due to the high source dose rates.

• RCRA requirements to detect liquid in the annular spacebetween the MCO and staging tubes.

• Microbiological Influenced Corrosion (MIC) affects on theStainless Steel (SS) MCO due to high MCO temperatures.

• Venting and purging of staging tubes due to hydrogenbuild-up in the MCOs due to high MCO^temperature.

• MCO/Cask drop evaluation over the operating floor.

• Emergency response capability in the event of a sustainedloss of cooling, e.g. due to DBE or loss of power, toprevent unacceptable high MCO temperatures.

3.2 INTRODUCTION

In accordance with the Statement of Work, Revision 5, dated April21, 1995 in Work Order TVW-SW-37052, Modification No. 90,individual Trade Study Reports have been prepared and are includedin this section. Each report is independent of the others ,•however, each study is based on requirements defined in the BaseCase Concept 2D description, Section 2.0. A cost summary ispresented in Table 3-1. The cost and schedule basis for the TradeStudies is identical to that defined in Sections 2-4 and 2-5, ofthe Base Case Concept 2D.

In terms of the Construction schedule, it appears only Task "H",RCRA Functions: Prevention and Detection of MCO leaks, would havean impact on the proposed construction schedule and date. It isestimated that RCRA compliance would extend the facility completiondate by a minimum of two months.

No cost data has been provided for Task "G", Damp-Dried MCO, as theanalysis demonstrated that it was not feasible to adapt the CSB tocomply with the functions and requirements for the SNF CSB.

1 0 OBJECTIVE

The objective of Trade Study Task "A" is to investigate therequirements for a Safety Class 1 (SC-1) confinement of theoperating area above the storage vault.

2.0 SUMMARY

A SC-1 HVAC system is provided for the Operating Area which iscapable of maintaining negative pressure during normal andDesign Basis Accident (DBA) conditions. The Operating Areastructure will be upgraded for SC-1. Emergency power isprovided to the HVAC system and the associated equipment by aclass IE emergency generator system. A minimum of two trainsare required to meet the single point failure criterionassociated with safety class systems. It is estimated that$1.7 million in direct cost and $840,000 in Engr/PM/CM costwill be added to the construction cost to provide SC-1operating requirements. Should the safety analyses determinethe site helicopter crash and design basis fire are credibly,then the cost of the SC-1 structures would increase.

3 . 0 FACILITY DESCRIPTION AND EVALUATION

3.1 Structural

The facility structural system and materials of constructionfor Task A requirements will be essentially the same as thatof Concept 2D. The SC-1 confinement of the operating floorarea above the storage vaults requires the structure to be

• classified as SC-1 also. The existing shelter is classifiedas SC-3 structure but designed for SC-1 Design BasisEarthquake (DBE) anchored at 0.35g Peak Ground Acceleration(PGA) to prevent collapse over the concrete vault. Inaddition to DBE, the building will have to be evaluated forother DBAs such as design basis wind, ashfall, fire, and windgenerated missile. The operating shelter building structuralsteel, siding and roof deck cost would increase byapproximately 10 percent. Current safety analysis has assumedfire as being not credible within the operating area. Shouldfuture fire hazard analysis be shown as credible, the buildingsteel framing system will have to be fireproofed to provide 2hour resistance rating.

The existing wall system, consisting of corrugated 22 gagesteel exterior panel and 22 gage flat liner interior panelwith insulation between them, would be specified to provide anadequately sealed enclosure for maintaining negative airpressure within the building. If for SC-1 the site securityhelicopter crash is considered credible, as it was for the

A-l


We3t:.nghouse v.anford Company Government Serv icesWKC P.O. TVW-3W-370252 Contract C4436306

HWVP proj ect, the steel building will not meet thisrequirement. A concrete structure of 24 to 36 inch thickwalls and roof would be required for helicopter crash. If thehelicopter crash becomes a requirement it would add asignificantly to the facility cost, and add 2 to 3 months tothe design/construction schedule.

Section 1320-5.4 of DOE 6430.1A states that irradiatedfissile material storage facilities need not be protected frommissiles, but shall be designed from massive collapse of thebuilding structure or the dropping of heavy objects on to thestored SNF as a result of building structural failures. Thisrequirement could be met by designing to SC-1 DBAs.

The mechanical room containing the SC-1 HVAC equipment and theemergency generator room will be designed to withstand the NPHforces appropriate for SC-1 requirements.

3.1.1 Structural Issues

The structural issues described for concept 2D, Section 2.2.1,are also applicable to this task. In addition the two DBA's,fire and helicopter crash, if determined credible would impactsignificantly the building cost since a concrete structurewould be necessary for conforming to these DBAs. Therequirements for other DBAs can be met with some modificationto the existing operating steel shelter.

3.2 HVAC System

The block flow diagram for the HVAC System for the Operating• Area is shown on Figure 3-1. This HVAC system is designed toprovide confinement in the operating areas during normal andDBA conditions. The HVAC supply system consists of two 18,000CFM air handling units (AHU-1 and 2) and the exhaust systemconsists of exhaust fans (EF-1 and 2) and two stage HEPAfilter plenums (PF-1,2,3 and 4) . The capacity of each filterplenum is 9,000 CFM. The system is capable of diluting thehydrogen and Kr-85 to acceptable levels by introducingsufficient amounts of outside air. The air from the OperatingArea is exhausted to the atmosphere through a SC-1 exhauststack. Following a DBA only one train of the exhaust systemwhich is SC-1 is required to operate. The building layoutshown on Figure 3-2 has been modified to accommodate theadditional space required to handle the SC-1 HVAC system.

3.3 Electrical System

Based on the requirements of the SC-1 HVAC system and theassociated equipment required to maintain confinementfollowing a DBA, the size of the emergency SC-1 generators is

estimated at 80 KW. This is based on the assumption that noheating is required after a DBA event. The additional spacerequired to accommodate the generators and associatedelectrical and control equipment is indicated on Figure 3-2.

3.4 Plot Plans

A plot plan for the Concept 2D is shown on Figure 3-2. Thisoverall plan includes the additional requirements for a SC-1HVAC confinement system, emergency generators and theassociated equipment.

4.0 SCHEDULE

Provided a site helicopter crash is determined not to be acredible accident, no impact is anticipated to the facilitycompletion date indicated in the Concept 2D base case.

5.0 COST ESTIMATE

The structural steel costs for the operating shelter willincrease by approximately 10 percent, for the Operating HVACMechanical Area by 20 percent, and for the Emergency GeneratorArea by 20 percent due to SC-1 design requirements. Noallowance for fireproofing and helicopter crash is included atthis time.

The assumptions, exclusions, and basis for the estimate remainthe same as for the Concept 2D Feasibility Study. Thedifference in the direct cost from the baseline Concept 2Destimate is:

Structures, add $ 131,000HVAC, add $ 517,000Elect, add $ 101,000I&C, add S 962.000

1.0 OBJECTIVE

The objective of Trade Study Task "B" is to determine theeffects of changing the Base Case Concept 2D by removing theMCO Receipt and Staging Function and Area.

2.0 SUMMARY

The results of this study show that the receipt and stagingfunction and area can be removed from the SSF provided the MCOis shipped in a bottom loading cask and that the MCO isserviced (purged and water level checked) before shipping.The size of the receipt and staging area would be smaller. Itis estimated that approximately $3.2 million may be saved bynot constructing this area; however, no reduction in thecompletion schedule is anticipated.

3.0 FACILITY DESCRIPTION AND EVALUATION

3.1 Plot Plans

Figure 3-1 shows the floor plan of Concept 2D SSF with TradeStudy Task B. This is the same as the original feasibilitystudy base case Concept 2D except for the Rail Tunnel/CaskUnloading Area.

3.2 Rail Tunnel/Cask Unloading Area

3.2.1 General Description

The Rail Tunnel/Cask Unloading Area is a facility of about• 4,000 square feet attached to the CSB at the northwest corner.This facility interfaces with the MCO Storage Tube Area via atransfer cart. The main functions of this area are to safelyreceive and handle incoming MCOs for placement in the storagetubes prior to stabilization. The packaged MCOs are deliveredinside a bottom loading transport/facility cask via rail caror truck one at a time.

The bottom loading transport/facility cask will be similar tothe bottom loading MCO shield cask as described in the basecase except that it must also be designed as a shipping cask.

The Rail Tunnel/Cask Unloading Area will be used as a washarea cask unloading/loading for rail cars and loading on tothe transfer cart.

Two railroad cars and a truck trailer parked in parallel canbe accommodated inside. A permanent ceiling installed liquidspray arrangement allows wash/decon of the shipping cask upper

section. Hand held wash/decon lances are available for thelower areas.

The casks will be unloaded from the railroad cars or truck andloaded on to a transfer cart. A 120 ton overhead crane, witha 10 ton auxiliary hoist running in the east/west directionservices this area. The transfer cart runs on rails at floorlevel and transfers the bottom loading transport/facility caskbetween the rail tunnel/cask unloading area and the canisterstorage operating area.

3.3 Findings

3.3.1 Impacts

The size of the Rail Tunnel/Cask Unloading Area is reducedfrom the base case Concept 2D of approximately 10,000 to 4,000square feet for Task B.

The bridge crane in the Rail Tunnel/Cask Unloading Area musthave a larger capacity to handle the heavier cask. For TaskB the crane would have a capacity of 120 tons vs 110 for thebase case.

For the base case only one bottom loading handling cask isrequired but for Task B approximately 6 are required.

3.3.2 Advantages/Disadvantages

The advantages of removing the MCO receipt and stagingfunction and area are:

• Smaller and less costly building.

• No water pools and associated water treatment system.

• No below grade pits in the Rail Tunnel/Cask UnloadingArea.

• No MCO servicing area.

The disadvantages of removing the MCO receipt and stagingfunction and area are:

• Capacity of the bridge crane increases.

• The design of the bottom loading transport cask will bemore complicated than a bottom loading facility cask.

• Increase the number of casks.

CSB Trade SCudy Fluor Daniel, Inc.Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

3.3.3 Concerns/Uncertainties

The concern of removing the MCO receipt and staging area is:

• With no MCO servicing stations the MCO cannot be purgedor water level checked and adjusted at the SSF.

There are no uncertainties with removing the MCO receipt andstaging area at this time.

4.0 SCHEDULE

With the size and complexity reduction of the Rail Tunnel/CaskUnloading and with the removal of the MCO Receipt and StagingArea no impact is anticipated to the facility completion dateas indicated in the Concept 2D base case.

5.0 COST ESTIMATE

Assumptions, exclusions, and basis for the estimate remain thesame as for the Concept 2D Feasibility Study. The differencein the direct cost from the baseline Concept 2D estimate is:

Structures, deduct <$ 570,000>Mechanical, deduct <$ 1,568,000>Engr/PM/CM, deduct <$ 1.049,000>Total direct cost reduction <$ 3,187,000>

1.0 OBJECTIVE

The objective of Trade Study Task "C" is to determine theeffects of changing the original feasibility study Base CaseConcept 2D by removing the cask decontamination function andarea (wash area).

2.0 SUMMARY

The results of removing the cask decontamination function andarea will reduce the size of the receipt area and amount ofequipment. It is estimated that approximately $1.2 millionmay be saved by not constructing this "area; however, noreduction in the completion schedule is anticipated.


3.1 Plot Plans

Figure 3-1 shows the floor plan of the Concept 2D SSF withTrade Study Task "C". This is the same as base case Concept2D except for the removal of the wash area from the RailTunnel/Cask Unloading Area.



The Rail Tunnel/Cask Unloading Area is a facility of about6,600 square feet attached to the CSB at the northwest corner.This facility interfaces with the MCO Storage Tube Area via a

• covered water canal as shown in Figure 3-1. This task is thesame as the base case except for the following changes:

• Removal of the wash area and its associated pumps, tanks,and holding tanks.

3.3 Findings

3.3.1 Impacts

The size of the Rail Tunnel/Cask Unloading Area is reducedfrom the base case of approximately 10,000 to 6,600 squarefeet.

The cycle time for the MCO/Transport Cask within the RailTunnel/Cask Unloading Area would be reduced by about 2 hoursby removing the wash area.

1.0 OBJECTIVE

The purpose of Trade Study Task "D" was to determine changesto facility functions, technical requirements/ identify riskand safety issues, and evaluate the impacts to the costestimate, and design/construction schedule due tosimplification of the rail service to one track with a passingtrack outside the facility, versus two tracks used in theoriginal feasibility base case Concept 2D.

The work was performed under Task "D" of the Statement ofWork, Revision 5, dated April 21,1995 in Attachment 1 to WHCWork Order TVW-SW-370252, Modification 09-0.

2.0 SUMMARY

Except for the smaller size of the railcar Wash Area and theCask/MCO Unloading and Storage Area due to the elimination ofone track within the facility, there are no significantchanges to facility functions and technical requirements. Therisks, technical and safety issues as enumerated in theConcept 2D Feasibility Study Report remain unchanged. There isno impact to the design and construction schedule as given forthe base case.

The Cask/MCO transportation on one track into the facilitywill be able to handle 3.4 shipments per day as opposed to 4in Concept 2D. The reduction in the estimated direct cost ofthe facility from the Concept 2D case will be approximately$98,000.00 and the cost of Engr/PM/CM is approximately$49,000.


3.1 Plot Plan

Figure 3-1 shows the master site plan for Task "D" for the onerail spur entering the CSB. The overall plot showing variousbuildings floor plans is shown in Figure 3-2 with the reducedfootprint of the Wash Area and the Cask/MCO Unloading AreaBuildings. A Change Room area has been added.

3.2 System Descriptions

The facility system descriptions are similar to those given inthe Concept 2D Feasibility Study Report. The elimination ofone rail track will reduce the track length by about 250 feet; reduce the Cask Wash Area by approximately 1040 square feet;and reduce the Cask/MCO Unloading and Storage Area by about640 square feet. A 1550 square feet area has been added for

the Change Rooms between the Cask/MCO Unloading and theEquipment/Office Buildings.

There will be some change in the material flow in the CaskWash and Unloading Areas when using one rail track. It ispossible to receive and handle 1 Cask/MCO every 7 hours (3.4per 24 hour workday). Figures 3-4 and 3-5 depict the tasks,sequences, equipment, and estimated time required to performthe tasks.

3.3 Facility Issues

The facility issues and concerns described*tor the Concept 2DFeasibility Study are also applicable to this Task "D" study.A single rail system in the facility is able to handle 3.4Casks/MCOs per 24 hour workday.

4.0 SCHEDULE

The design/ construction schedule for the Concept 2DFeasibility Study is also applicable to this Task study and nonew impacts are identified.

5.0 COST ESTIMATES

Assumptions/ exclusions, and basis for the estimate remain thesame as for the Concept 2D Feasibility Study. The differencein the direct cost from the baseline Concept 2D estimate is:

1.0 OBJECTIVE

1.1 Background

The Canister Storage Building as originally designed in 1992for the Hanford Waste Vitrification Project contained storagetubes made of ASTM A242 weathering steel (e.g., Corten brandby U.S. Steel). During the Staging and Storage FacilityFeasibility Study, stainless steel tube material was proposedfor the options involving water-filled tubes. Stainless steelwas chosen based on 50 °F deionized water in the tubes and a40-year design life. The Feasibility Study Final Report notedthe unresolved technical issue of corrosion of the stainlesssteel in stagnant (oxygen-depleted) water.

The objective of the trade studies is to resolve technicalissues related to the usage of the Canister Storage Buildingto safely stage and store N-Reactor spent fuel now located atK-Basin 100KW and 100KE. The Trade Study Task "E11 Statementof Work is to determine the technical feasibility of non-stainless steel water-filled storage tubes and recommendmaterial to resist wet corrosion for only 7 years versus 40years.

1.2 Purpose and Need

Although the building will be used for 40 years {or more) , thestaging phase when the tubes could be filled with water willnot exceed 7 years. Each of the three vaults in the originaldesign contains 220 tubes. The present fabricated cost ofeach stainless steel tube was estimated to be $43,300,

• compared to $17,100 for weathering steel. Carbon steel wouldcost 30% less than weathering steel. The installed cost ofstainless tubes would be a major portion of the total buildingcost. As noted in the Feasibility Study Final Report,corrosion of stainless steel is possible in stagnant water.

2.0 SUMMARY

A review of literature on corrosion due to stagnant waterrevealed a threat to not only the storage tubes, but also theinside and outside of the MCOs. Pitting corrosion ofstainless steel in oxygen-depleted water is well-known, as isthe fact that this form of corrosion is accelerated bybacterial action. The iron-oxidizing bacteria whichaccelerate the corrosion are found in spent fuel storagepools. The rate of local corrosion is unpredictable, rangingfrom slight pitting to complete penetration within a fewyears.

E-l



Although the options for tube design are discussed below, noneof these options solves the more important problem ofcorrosion of the MCO from the inside by stagnant water.

Any option with water-filled tubes requires the addition of asystem for detecting that a tube leak has occurred and findingthe leaky tube. Even a single undetected tube failure mighthave severe consequences if this could also cause MCO failuredue to high temperature, which might result in contaminationof the concrete vault around the tubes. The tube-leakdetection system is yet to be defined, subject to many safetyand feasibility issues. The building must contain featuresnecessary for recovery and clean-up in the event of leakage.

If the water in each of the tubes is treated and regularlymonitored to maintain the pH above 10.5 with an acceptableconcentration of biocide, then it is likely that there will beno unacceptable corrosion due to stagnant water when the tubesare constructed of bare carbon steel or weathering steel.Weathering steel (such as Corten) probably would be suitablefor staging and storage. Weathering steel was determined tobe preferable to carbon steel for HWVP storage. The impactabsorbers in the tubes would have to be redesigned so thatwhen water treatment chemicals are added, the chemicals willmix evenly between the top and bottom of the tube. Because ofthe uncertainty intrinsic to corrosion prediction in thesecircumstances, and the severe consequences associated withtube failures, further investigation is recommended.Corrosion literature should be searched for reports ofcorrosion of stainless steel and weathering steel (or carbonsteel) in stagnant treated water. Testing is recommended to

• verify the material choice and to determine the requiredinterval for monitoring and replenishing the treated water.

If further investigation shows that it is not practical totreat and monitor the water in the individual tubes, then theonly design using well-developed technology {known to FluorDaniel) which assures the integrity of all tubes and MCOs overa period of 7 years requires an interconnecting watercirculation system and stainless steel tubes. Other possibledesigns are more expensive, require development/testing and/orinvolve a significant chance of at least one tube failurecaused by undetected damage during MCO insertion. Epoxycoating is an option which appears acceptable, subj ect toverification that there is no problem with dry MCO damageduring MCO placement.

Although it may be feasible to connect the tubes and circulatetreated water through them, this design is more expensive thanthe base case, and therefore is a step in the wrong direction.A system of connected tubes is functionally similar to an

expensive version of the open pool Alternative 1 of theFeasibility Study. Rather than estimate the cost of anundesirable option, it should suffice to say that the costwould exceed that of Alternative 2A in the Feasibility Study.


3.1 System Description

The N-Reactor fuel consisted of uranium metal with zirconiumcladding. The spent fuel has been stored underwater in theeast and west K-Basin pools in order to cool the fuel andprevent contact with air. Uranium metal can react with air inan uncontrolled, highly-exothermic (pyrophoric) manner. Thispyrophoric reaction could destroy the fuel containers andrelease the spent fuel in the form of smoke. During thestaging phase of operation, metallic fuel contained instainless steel Multi-Canister Overpacks (MCOs) will bemaintained at 100 °F or less in the tubes using refrigeratedforced-air cooling on the outside of the tubes. Although itis not essential to have water in the tubes, water is by farthe cheapest and most effective heat transfer fluid. The useof other fluids in the tubes (such as air, nitrogen, helium,or fluorocarbons) will result in greater cooling flowrequirements or higher MCO temperatures. Later, the fuel willbe removed and stabilized in an adjacent facility. In thestabilization process, fuel surfaces are oxidized to preventfurther reaction and to allow higher-temperature storage.Then, in the storage phase, the returned stabilized fuel inMCOs will be stored in dry tubes and maintained at 400 °F orless by natural convection of outside air.

An MCO is inserted into a tube by an overhead crane equippedwith a grapple which grips the top of the MCO. The MCOdimensions are 24" OD and 15'-1" long. The maximum MCO weightis 13,100 lb. The maximum heat generation rate is 482 W perMCO.

Figure 3-1 shows a typical tube with two MCOs. The top of thetube is covered with a concrete shielding plug. The plug ismoved aside when an MCO is inserted. The plug seals the tube,but contains two valved tubing connections. One connectioncould allow the gas space above the MCOs to be monitored andpurged during operation. The other connection has a HEPAfilter and would be attached to a relief valve to vent thetube before gas pressure could lift the plug. Below the plugis an embedded funnel which aligns the MCO into the tubeduring insertion.

Two MCOs will fit in each storage tube, which is 34'-3" fromthe base to the funnel. The bottom 23'-4" of the tube is 27"

Stagnant, deionizedwater at approximately 100 °F would cover the MCOs. With twoMCOs in place, the water volume is 24.8 cubic feet or 185gallons.

3.2 Evaluation

Concern for the design of water-filled tubes is not thegeneral corrosion of the carbon steel tubes but theMirobiolgically Influenced Corrosion (MIC) of the carbon steelor weathering steel tubes and the stainless steel MCOs due tostagnant water.

MIC is a well-known corrosion phenomenon and is recognized asa serious problem affecting industrial facilities, includingnuclear sites. MIC was a major concern of WestinghouseHanford Company on the HWVP project, based on experiencereported by the Tennessee valley Authority with stainlesssteel piping (Guthrie and Kuzniak); With the wet design, thecarbon steel tubes and the stainless steel canisters (insideand outside) are at risk of MIC. The corrosion could rangefrom minor pitting to complete through-wall penetrations.

Methods of preventing MIC are having constant flow above 5ft/sec to prevent microbes and nutrients from accumulating onthe materials surface, treating the water with a biocide tocontrol microbial population, raising the pH to 10.5 orgreater, or applying cathodic protection. An effectivemonitoring program is essential in controlling microbial

' population.

Provided MIC is prevented, one option for the material ofconstruction for stagnant water-filled storage tubes is carbonsteel. Weathering steel, ASTM grade A242, is also acceptablebut more expensive. General corrosion of carbon steel tubesis not a major concern due to the fact that the extent ofcorrosion is dependent on the amount of water and surface areaexposed to the water. Carbon steel will only corrode untilthe dissolved oxygen is consumed. The extent of penetrationof corrosion is 0.0006 inch per sq. in. of surface per gallonof water. With the large amount of surface area and therather small amount of water (approximately 185 gallons) thecarbon steel would perform satisfactorily in this application.If MIC is prevented and the corrosion products derived fromgeneral corrosion are not a problem, then carbon steel is anacceptable material for the tubes.

Alternative material to eliminate or reduce the corrosionproducts and possibly avoid MIC of the tubes could be epoxy-

coated carbon steel or bare carbon steel with cathodicprotection. If epoxy-coated carbon steel is considered thedesign must incorporate the standard preparation techniquessuch as rounded corners, contoured welds and clean base metalsurface. Any pinhole flaw in the coating would result inrapid corrosion of the steel behind the flaw. Coating flawsduring fabrication can be detected by holiday testing(electric discharge testing). Damaging of the coating duringcanister placement seems likely with the current placementmechanism shown in the feasibility study. However, a softprotective bumper around the bottom edge of the MCO could beadded to protect the coating during placement. Thefeasibility of cathodic protection for" this applicationrequires further consideration of maintainability. Mostimportantly, protection of the tubes does not solve the moreserious problem of corrosion of the MCO.

From a corrosion viewpoint, it would be best to eliminatewater as a cooling media for the MCO. If a change is notpossible because of heat transfer limitations, methods ofpreventing MIC should be implemented. Prevention of MIC wouldrequire a method of circulating biocide-treated water betweentubes or monitoring the water quality in each tube. Treatingor monitoring the water inside the MCO would be required,which might be a difficult or costly task. If MIC cannot beprevented, materials with an assured resistance to MIC must beinvestigated and tested. The referenced report by Guthrie andKuzniak suggests that titanium may be a suitable material.

4.0 SCHEDULE

• The choice of storage tube material does not affect the designor construction schedule of the revised Canister StorageBuilding.

5.0 COST ESTIMATES

If unacceptable corrosion of the MCO and tube cannot beprevented by treatment and monitoring the water in each tube,the cost of circulating treated water through the tubes toavoid stagnant conditions will exceed that of Alternative 2Ain the Feasibility Study. Although this water-circulationoption will prevent unacceptable corrosion of the storagetubes, it does not address internal corrosion of the MCO bystagnant water.

If the water in the tubes can be treated and monitored toprevent unacceptable corrosion by stagnant water, thenweathering steel (such as Corten) is suitable for the tubes.This design has been estimated as Concept 2D.

Figure 3-1 CSB Trade Study, Task "F" Floor Plan



1.0 OBJECTIVE

The objective of Trade Study Task "F" is to determine theeffects of changing the original Feasibility Study Base CaseConcept 2D by reducing MCO shipments from 4 to 2 per day.

2.0 SUMMARY

The results of reducing the MCO shipments from 4 to 2 reducesthe size of the receipt area by removing one of the tworailroad tracks coming into the building and reduces thequantity handling equipment. It is estimated thatapproximately $274,000 may be saved by not constructing thisarea; however, no reduction in the completion schedule isanticipated.


3.1 Plot Plans

Figure 3-1 shows the outline of Concept 2D SSF with TradeStudy Task "F". This is similar to the base case Concept 2Dexcept for the Rail Car Wash Area and Rail Tunnel/CaskUnloading Area.



The Rail Tunnel/Cask Unloading Area is a facility of about8,000 square feet attached to the CSB at the northwest corner.

• This facility interfaces with the MCO Storage Tube Area via acovered water canal as shown in Figure 3-1.

This task is the same as the base case except for thefollowing changes:

• Only one MCO servicing station is required.

• The size of the clean MCO/MCO Overpack/Cask Storage Rackcan be reduced to 1/2 of the base case rack.

• The Unloading Pool Jib Crane and the Cask Loading Pit JibCrane are not required. The operations performed by thejib cranes can be done by the 10 ton hoist on the bridgecrane because of the reduced use of this crane.

• Only one rail track is required to service the 2shipments per day.

The operations for Task "F" within the Rail Tunnel/CaskUnloading Area will be the same as the base case.

3.3 Findings

3.3.1 Impacts

The size of the Rail Tunnel/Cask Unloading Area including thewash area, is reduced from the base case Concept 2D ofapproximately 10,000 to 8,100 square feet.

Only one rail track is required.

3.3.2 Advant age s/D i s advant age s

The advantages of two MCO shipments per day are:

• Smaller building.

• Less handling and servicing equipment for the MCOs.

The disadvantage of two MCO shipments per day is:

• It will take longer to remove the spent nuclear fuel fromK-Basins.


There are no additional concerns or uncertainties from thebase case.

4.0' SCHEDULE

With the reduction in the size and complexity of the RailTunnel/Cask Unloading Area no impact on the schedule isanticipated from Concept 2D.

1.0 OBJECTIVE

The objective of Trade Study Task "G" is to evaluate handlingand staging requirements for MCOs shipped drained, damp-driedfrom K-Basin. Determine cooling requirements for arefrigerated air system during staging operations andinvestigate natural circulation cooling system during storageoperations.

2.0 SUMMARY

The results of the thermal analyses for MCOs shipped drained,damp-dried from K-Basin for staging in 2-vaults indicates thatit is not feasible to maintain MCO temperatures at 100 °F witha refrigerated forced air system. However, during the storageoperation the MCO temperature can be maintained at 270 °F bya passive ventilation system, this is below the limitingcriteria of 400 °F for storage operations.

3 . 0 EVALUATION OF MCO HANDLING/STAGING AND COOLING REQUIREMENTS

3.1 Evaluation of MCO Handling and Staging

There will be no significant impact in the conceptualizedparameters for handling and staging of MCO's in the Concept2D.

The immediate affect on handling a dry MCO will be anapproximate 1 ton reduction in weight of a loadedtransportation cask due to the weight of water. Thisreduction is not considered large enough to re-size the cask

• handling cranes for this trade study.

3.2 Evaluation of MCO Cooling Requirements

This section documents the results of a series of thermalanalyses that were performed to assess the feasibility ofmeeting the Multi-Canister Overpack {MCO} temperaturerequirements during dry staging with the Concept 2D Stagingand Storage Facility (SSF). These analyses were performed forforced refrigerated air and passive ventilation systems.

The thermal feasibility analysis is based on staging ofdrained, damp-dried MCOs in air filled tubes in vaults 1 and2 {third vault contains no tubes) with a forced refrigerationair cooling of the tubes during staging. MCOs are removed andreturned to the tubes after stabilization. After all fuel isstabilized, the passive air ventilation system is madeoperational.

3 2.1 Design Basis Assumptions

The following design basis assumptions were used for thethermal analyses:

• The heat generation rate was based on a total 880 MCOs.Twenty percent are assumed to be at the upper limit("maximum") (482 W) and the remaining eighty percent areassumed to be at the nominal value ("average") (221 W) .Due to the preliminary nature of the heat transfercalculations a ten percent safety factor was used for theheat generation rate. Additional heat loads were addedfor building heat gains.

• The heat generation for the "maximum" case (482 W) perMCO was used for calculating the MCO temperature assumingthat it is located at the end of the vault. Each MCOconsists of five canisters, each storage tube containstwo MCOs, and each vault contains 220 tubes.

• The design basis required staging/storage conditions areas follows:

Staging: Maximum MCO temperature at 100 °F.Storage: Maximum fuel centerline temperature at 400 °F.

• During the staging operation the MCO provides primaryconfinement and the air filled storage tubes provide thesecondary confinement. It is assumed that the interiorof the storage tubes are isolated from the vault, whichwould prevent the vault from getting contaminated.

• The total flow is assumed to be evenly and uniformlydistributed around each of the containment tubes. Thisis a critical assumption that must be assured by designand verified by additional analyses using ComputationalFluid Dynamic (CFD) techniques.

• The heat transfer coefficients for air were calculated atthe point of maximum vault air temperature.

• One dimensional (radial) heat transfer only. Two-dimensional (radial and axial) heat transfer was notmodeled.

• Heat transfer by radiation between the tubes was notconsidered.

3.2.2 Summary of Results

The results of the thermal analyses during staging are shownin Table 3-1 and involve various combinations of drained,damp-dried MCOs surrounded by air in tubes for differentventilation flow rates.

The results indicate that it is not feasible to maintain theMCO temperature at 100 °F with a refrigerated forced airventilation system with a supply air temperature of 35°F.With 200,000 CFM system and a supply air temperature of 35 °F(Concept 2A of the SSF Feasibility Study) the MCO temperaturecan only be maintained at 173 °F based "on the above heatgeneration rate. The temperature of 35 °F was selected tomaintain the same basis as the previous feasibility studyalternatives. The MCO temperature is calculated on the basisthat the MCO is located at the end of the vault with thelimiting heat load. (The MCO temperature could be maintainedat 100 ° F with 200,000 CFM supply air at minus 37 °F, this isnot feasible).

The results of the thermal analyses during storage operationwith the existing CSB design concept, assuming the same intakestructure, vault size (2-vaults) and exhaust stack (height anddiameter) indicates that an MCO temperature of 270 °F can bemaintained by a passive ventilation system. This is based onan inlet air temperature of 115 °F (same design basis as CSB)and a ventilation flow rate of 53,000 CFM.

The above results indicate that it is not feasible to use therefrigerated air system to maintain the MCO temperature below100 °F during the staging operation. However; the passiveventilation system can maintain the MCO temperature below the400 °F limit during the storage operation.

It must be emphasized that these are rough conservativefeasibility analyses using limited design information and donot cover all limiting or upset conditions. More detailedanalyses are required using CFD techniques to cover alllimiting and upset conditions and to verify some basicassumptions. Also no analysis was performed for MCOs storedin an overpack.

1.0 OBJECTIVE

Part of the mission of the SNF CSB is to provideenvironmentally sound staging and storage of K Basin SNF.This mission may require compliance with the Federal ResourceConservation and Recovery Act (RCRA). The purpose of TradeStudy "H" is to identify the impacts on the SNF CSB Projectassuming compliance with RCRA, and specifically to identifythe design functions required to prevent and detect MCO leaks.

2.0 SUMMARY

Several SNF CSB functions would be required to comply withRCRA. Some already are a requirement in the base case (e.g.,MCO retrievability) and would not cause a cost/schedule impactfor the purpose of this trade study. Others are not in BaseCase 2D and would be required only to comply with RCRA {e.g.,thirty inch minimum separation between rows of MCOs, arequirement which probably would be waived because directvisual inspection of the MCOs would not be feasible).

Only one RCRA-required funct ion would cause s igni f icantcost/schedule impact, detection of MCO leakage within twenty-four hours. To achieve this function would appear difficultand expensive, regardless of the approach considered, andwould pose significant feasibly issues. Continuouslyoperating MCO leak detection would add approximately $4.5million to the facility cost and extend the scheduled facilitycompletion date by a minimum of two months. Given the BaseCase 2D design, featuring an MCO filled with water (theprimary heat sink) in a dry tube, potential safety andlicensing risk could be incurred by not including thisfunction, even if RCRA compliance is not a projectrequirement.

3 . 0 FACILITY DESCRIPTION AND EVALUATION

3.1 Applicability

The Federal Resource Conservation and Recovery Act (RCRA) gaveguidance to the Environmental Protection Agency (EPA) for the"cradle to grave" regulation of hazardous wastes. In general,RCRA regulates the generation, transportation, treatment,storage and disposal of hazardous wastes, and theseregulations are found in 40 CFR 260 to 270.

The State of Washington has obtained authorization from theEPA to administer the basic RCRA program. The WashingtonHazardous Waste Management Act (the Washington Act) parallelsthe federal RCRA requirements, and gives authorization to theDepartment of Ecology (Ecology) to regulate permitting for the

H-l


CSB Trade SCudy Fluor Daniel, Inc.Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract: 04436306

generation, transportation, treatment, storage and disposal ofhazardous wastes. The Washington regulations are contained inWAC (Washington Administration Code) 173-303, Dangerous WasteRegulations.

The applicability of WAC 173-303 to the SNF CSB is containedin 173-303-020, Applicability, which reads in part, "Thischapter 173-303 WAC shall apply to all persons who handledangerous wastes including, but not limited to owners andoperators of dangerous waste recycling, transfer, storage,treatment, and disposal facilities."

Since spent fuel elements potentially meet the requirements asa Washington State extremely hazardous waste (EHW), seesections 173-303-070 to 173-303-103, the SNF-CSB could requirea RCRA type permit from the Department of Ecology, seesections 173-303-800 to 173-303-840. This permit would be fora TSD (Treatment, Storage and Disposal) facility for thestorage of dangerous wastes.

3.2 The Regulation of MCOs (as either containers or tanks)

The regulatory requirements in WAC 173-303 are different forstorage of dangerous wastes in containers versus storage intanks. Section 173-303-040 defines a container as, "Containermeans any portable device in which a material is stored,transported, treated, disposed of, or otherwise handled," anda tank as, "Tank means a stationary device designed to containan accumulation of dangerous waste, and which is constructedprimarily of nonearthen materials to provide structuralsupport."

The main difference of the two definitions appears to bebetween a portable device and a stationary device. Since anMCO is a portable device, it appears to meet the definition ofa container. However, the storage of an MCO in a tube isessentially stationary, and as a result, the regulators(Ecology) may classify the MCOs as a tank.

Since the classification of the MCOs may be that of either acontainer or a tank, the regulatory requirements for bothclassifications are presented in this analysis.

3.3 Containers

WAC 173-303-630 regulates the use and management of containersused to store dangerous wastes.

3.3.1 173-303-630(2) Condition of Containers

3.3.1.1 Regulatory Requirements

H-2



If a container holding dangerous waste is not in goodcondition (e.g., severe rusting, apparent structural defects)or if it begins to leak, the owner or operator must transferthe dangerous waste from the container to a container that isin good condition or manage the waste in some other way thatcomplies with the requirements of 173-303, including that forleaks and spills.

3.3.1.2 Regulatory Impact

The above requirement can be met with retrievable MCOs, sometype of inspection system (as discussed in 3.3.3 below), andan overpack capability for leaking MCOs. Retrievability andoverpack capability are provided in the base case design.

3.3.2 173-303-630(5) Management of Containers

3.3.2.1 Regulatory Requirement

Subsection (c) requires a minimum thirty-inch separationbetween isles of containers holding dangerous waste(s), and arow of drums must be no more than two drums wide.


These requirements appear to be for containers such as55-gallon drums and it is not clear how a regulator wouldapply the requirements to MCOs. A strict application mightrequire a minimum thirty-inch separation between the storagetubes. This is a factor that would need interpretation by theregulators.Since lethal radiation dose rates preclude direct visualinspection of MCOs, however, these requirements would have nopurpose for the SNF CSB. Waiver of this requirement (nochange from the base case design) would meet the intent of theregulation.

3 .3 .3 173-303-630(6) Inspections


At least weekly, the owner or operator must inspect areaswhere containers are stored, looking for leaking containersand for deterioration of containers and the containment systemcaused by corrosion, deterioration, or other factors.


This is another requirement that is directed at conventionalcontainers, such as 55-gallon drums. For MCOs in a storagetube, the regulators may agree to some type of acceptable

H-3


CSB Trade Study ' Fluor Daniel, Inc.Westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

weekly leak inspection system. This is another factor thatneeds interpretation by the regulators.

Compliance with the letter of this requirement clearly is notfeasible because of the extremely high MCO dose rate. Weeklydirect observation of each MCO, even by remote means such asa fiber optics, clearly is not feasible. CCTV would not fitinto a tube. A contxnuously operating leak detector in eachtube should, however, meet the intent of this requirement.

3.3.4 173-303-630(7) Containment


Container storage areas must have a containment system that iscapable of collecting, holding and removing spills and leaks.Spilled or leaked waste must be removed from the containmentsystem in an timely manner as is necessary to preventoverflow.


The storage tubes will meet the containment system requirementto collect and hold spills and leaks, if the tubes aredesigned to be watertight. (Note: The HWVP CSB design doesnot require the tube to be watertight [leaktight]. Groutedanchor bolts penetrate the bottom plate of each tube.)

Tube/facility design also would have to provide for somemanner of removing liquid that has leaked from an MCO.Because of the radiation field, removal of liquid would haveto be accomplished remotely, after both MCOs have been removedand the leaking MCO has been placed in a MCO overpack.

3.3.5 173-303-630(8) Special Requirements for IgnitableWaste


The owner or operator shall design, operate and maintainignitable waste container storage in a manner equivalent withthe Uniform Fire Code.


Section 173-303-630 (8) is applicable if the generation ofhydrogen in the MCOs is considered possible. However, as longas a sufficient amount of HVAC air exists to dilute hydrogento levels below the lower explosive limit, which is expected,the requirements of 173-303-630(8) might be waived. If not,the spacial requirements required by the Uniform Fire Code may

H-4



be necessary (this is another area where the regulators wouldneed to be consulted).

3.3.6 Summary of Regulatory Impacts

A summary of the regulatory impacts for Base Case Concept 2Dand the classification of the MCOs as containers follows:

• The MCOs would have to be retrievable (already anintrinsic characteristic of the MCO conceptual design)

• Some type of continuously operating leak detection systemwould have to be provided in lieu of inspection, whichprobably is not feasible

• An MCO overpack capability would have to be provided(already provided in the Base Case)

• Depending upon interpretation, a minimum thirty-inchseparation (or other spacing arrangement) between storagetubes may be required, but would have no known purpose

• The design would have to include watertight storage tubesand provide for prompt (and probably remote) removal ofmaterial that has leaked from an MCO

• Since the entire SNF CSB facility has the potential to beradiologically contaminated, all drainage sumps alsoshould be provided with continuously operating leakdetection systems and provisions for removal ofaccumulated liquids

3.4 Tank Systems

WAC 173-303-640, Tank Systems, applies to owners and operatorsof facilities that use tank systems to treat or storedangerous wastes. Under the WAC regulations, the MCOs inConcept 2D would be considered the primary containment vessel(or tank) and the storage tubes would be considered thesecondary containment vessel.

3.4.1 173-303-640(4) Containment and Detection ofReleases:


In order to prevent the release of dangerous waste ordangerous constituents to the environment, secondarycontainment must be provided that meets the followingrequirements: secondary confinement systems must be designed(and installed and operated) to prevent any migration ofwastes or accumulated liquid out of the system to the soil,

H-5



ground water or surface water at any time during the use ofthe tank system, and the secondary confinement system must becapable of detecting and collecting releases and accumulatedliquids until the collected material is removed.

To meet these requirements, the secondary confinement systemsmust be provided with a leak detection system that is designed(and operated) so that it will detect the failure of theprimary or secondary containment structure or the presence ofany release of dangerous waste or accumulated liquid in thesecondary containment system within twenty-four hours.Spilled or leaked waste and accumulated precipitation must beremoved from the secondary containment system within twenty-four hours.

Secondary containment for tanks must include one or more ofthe following devices: a liner, a vault, a double-lined tank,or an equivalent device. External liner systems serving assecondary confinement must be designed (or operated) tocontain one hundred percent of the capacity of the largesttank within its boundary, and must be designed (and installed)to surround the primary tank completely.

The secondary containment requirement applies to ancillaryequipment (e.g., tubing and other penetrations of thecontainment pressure boundary) as well. (Some exemptionsexist).


In Base Case Concept 2D, the MCOs would be considered theprimary containment vessel and the storage tubes containingthe MCOs would serve as secondary containment. Thus, thedesign would have to provide for detection of leaks of theMCOs within twenty-four hours and removal of any material thathas leaked into a storage tube within twenty-four hours ofdetection. Considering the geometry of the storage tubes, therequirement on the secondary containment system for containingone hundred percent of the capacity of the primary vessels isreadily met, if the tubes are designed to be watertight.

3.4.2 173-303-640(7) Response to Leaks or Spills andDisposition of Leaking or Unfit-for-use TankSystems


A tank system or secondary containment system from which therehas been a leak or spill, or which is unfit for use, must beremoved from service immediately, and the owner or operatormust satisfy the following requirements:

H-6



• Cessation of use; prevent flow or addition of wastes.The owner must immediately stop the flow of dangerouswaste into the tank system or secondary confinementsystem and inspect the system to determine the cause ofthe release.

• If the release was from the tank system, theowner/operator must, within twenty-four hours afterdetection of the leak or, if the owner/operatordemonstrates that it is not possible, at the earliestpracticable time, remove as much of the waste as isnecessary to prevent further release of dangerous wasteto the environment and allow inspection and repair of thetank system to be performed.

If the leak was to the secondary confinement system, allreleased materials must be removed within twenty-fourhours or in a timely a manner as is possible to preventharm to human health and the environment.

• The owner/operator must immediately conduct a visualinspection of the release and prevent any furthermigration of the leak or spill.


These requirements are satisfied by having retrievable MCOs,watertight tubes, and the ability to detect and remove(probably remotely) any MCO leakage from inside the storagetubes. A leaking MCO probably could be retrieved and placedin an MCO overpack within twenty four hours. It probablycould be shown, however, that (remote) removal of MCO leakagefrom a storage tube within twenty four hours of detection isnot practicable.

3.4.3 173-303-640(9) Special Requirements for Ignitable(or Reactive) Wastes


Ignitable wastes must not be placed in tank systems unless:

• the waste is treated, rendered or mixed before orimmediately after placement in the tank system so thatthe resulting waste, mixture, or dissolution of materialno longer meets the definition of ignitable waste and (a)the storage does not generate extreme heat or pressure,fire or explosion or violent reaction (b) produceuncontrolled toxic gases in sufficient quantities tothreaten human health, (c) produce uncontrolled flammablefumes or gases in sufficient quantities to pose a risk of

H-7


CSB Trade SCudy Fluor Daniel, Inc.Westinghouse Hanford Company Government: ServicesWHC P.O. TVW-SW-370252 Contract 04436306

fire or explosions, (d) damage Che structural integrityof the facility or device containing the waste, and (e)through other means, threaten human health or theenvironment, or

• the waste is stored or treated in such a way that it isprotected from any material or conditions which may causethe waste to ignite or react.

The owner or operator of a facility which treats or storesignitable waste in covered tanks must locate the tanks in amanner equivalent to the National Fire ProtectionAssociation's (NFPA) buffer zone requirements for tanks.

Along with 173-303-640(9), WAC 173-303-395(1) regulatesprecautions to be taken with ignitable wastes.


As noted earlier, section 173-303-640(9) would be applicableif the generation of hydrogen in the MCOs is consideredpossible. However, as long as a sufficient amount of HVAC airexists to dilute hydrogen to levels below the lower explosivelimit, which is expected, the requirements of 173-303-640(9)would be satisfied using the provision in part (2) above, i.e.Section 3 .3-1.

If section 173-303-640(9) is applicable, a NFPA buffer zonerequirement might exist.

3.4.4 Summary of Regulatory Impacts

A summary of the regulatory impacts for the designs associatedwith Base Case Concept 2D and with the classification of theMCOs as tanks follows:

• Some type of system for detecting leaks in the MCOswithin twenty-four would have to be provided

• The design would have to provide for the removal of anyleaked material (from the MCOs) into the storage tubeswithin twenty-four hours after detection

• The MCOs would have to be retrievable (already acharacteristic of the Base Case MCO)

• Some type of system would have to be provided forinspecting storage tubes (after a leak from an MCO)

H-8



• The spent fuel would have to be stored in such a way thatit is protected from any material or conditions which maycause the (hydrogen produced by the) waste to ignite

3.5 Other Requirements

There are other regulations in WAC 173-303 that apply to thedesign of the SNF CSB facility, but these are very generic innature (e.g., siting criteria) and have not been includedhere.

3.6 Summary of Functions To Comply with RCRA Requirements

Several SNF CSB functions would be required to comply withRCRA, if the stored SNF were classified as "dangerous waste."These functions can be categorized as:

• Already a requirement in the original Feasibility StudyBase Case Concept 2D,

• Currently not a requirement in the Base Case, but shouldbe a requirement, whether or not RCRA compliance would berequired, and

• Currently not a requirement in the Base Case, but wouldbe required only for compliance with RCRA

Only the last category of functions, listed in Section 3.8below, would have cost/schedule impacts for the purpose ofthis trade study.

3.6.1 Functions already a requirement in the Base Case:

• MCOs would have to be retrievable.

• MCO overpack capability would have to be provided.

• SNF would have to be stored in such a way that it isprotected from any material or conditions which may causeit Cor the hydrogen produced by it) to ignite.Protective functions would include:

Adequate MCO coolingStorage tube ventilating/purging/inertingcapability"Explosion-proof" components (e.g., hoist/motor,limit switches) inside the handling cask/floorshield gates, and storage tube, andAn operating deck HVAC system capable of removingvented hydrogen before it reaches explosiveconcentrations.

H-9


CSB Trade Study ' Fluor Daniel, Inc.westinghouse Hanford Company Government ServicesWHC P.O. TVW-SW-370252 Contract 04436306

3.6.2 Functions currently not a requirement in the BaseCase, but should be a requirement, whether or notRCRA compliance would be required:

• The design would have to include watertight storage tubes[HWVP CSB design does not require the tube to bewatertight].

• The design would have to provide for prompt (and probablyremote) removal of material that has leaked from an MCO.

• Because the entire operating area of the facility has thepotential to be radiologically contaminated, all drainagesumps should be provided with continuously operating leakdetectors and provisions for removal of accumulatedliquids.

3.6.3 Functions currently not a requirement in the BaseCase, that would be required only for compliancewith RCRA:

• Continuously operating MCO leak detection (capable ofdetecting leakage within twenty four hours) would have tobe provided in lieu of inspection, which probably is notfeasible.

• Capability to inspect storage tubes, probably remotely,after a MCO leak.

• Depending upon interpretation by the regulator, a minimumthirty-inch separation (or other spacing arrangement)between storage tubes may be required. This would haveno known purpose, however, given that inspection bydirect observation is not feasible. A waiver of thisrequirement would be anticipated.

3.7 Detailed Schedule Impacts

• MCO leak detection:

If installation of detectors requires modification ofeach tube (e.g., watertight penetrations), then theduration of both tube procurement and tube installationcould be extended. If installation of detectors requiresmodification of the operating deck floor (e.g., embeddedcable conduits), then the construction duration for theoperating deck floor could be extended.

Because of the lead time required, procurement of the MCOleak detection system and other RCRA leak detection

H-10



systems should be initiated as soon as possible after adecision is made to provide these functions.

• Post-leakage inspection of storage tubes:

No anticipated effects on schedule.

• Minimum thirty inch separation between tubes

No anticipated effects on schedule, if waived.

3.8 Equipment Required to Implement RCRA Functions

The design functions to comply with RCRA would require thefollowing equipment:

• MCO leak detection (per tube, plus one central displaypanel):

In-tube sensorSignal path from sensor to display, via water-tightpenetration through tube or conduit to and throughoperating deck, plus cabling to display panellocation

The direct cost is estimated to be $3.0 million and the costof Engr/PM/CM approximately $1.6 million

• Post-leakage inspection of storage tubes:

No additional equipment would be anticipated above theinspection capability that would have to be built in toprovide the leakage removal capability referred to inSection 3.7 above.

• Minimum thirty inch separation between tubes

No additional equipment would be anticipated, if waived.

4.0 SCHEDULE

The procurement and installation of an MCO leak detectionsystem extend the facility completion date a minimum of twomonths.

Following is the rough calculation of heat transfer in the storage vaults. The assumptionsas well as calculation results can be used only as a first guess. Detailed calculation usingthe Computational Fluid Dynamics (CFD) technique is proposed on the next stage of thisproject.

Table 1. Number of Units in the Storage

There is a mixed heat transfer media: air or water inside the MCOs, air between MCOsand sleeves, and air as a cooling media in the vault.

There is 20% of the maximum heat decay fuel elements and 80% of the nominal heatdecay fuel elements. A single maximum heat decay element is releasing 3.44 W of heat.A single nominal heat decay element is releasing 1.56 W of heat.

It is assumed for conservative reason that 280 elements of maximum heat decay (3.44 W)can be loaded into a sleeve and located in the last row of the vault. This elements will beexpressed to the highest vault air temperature. For comparison a number of calculationsare made for the high loaded sleeve located at the beginning of the vault in the first rowand expressed to the intet airflow.

At the first stage, codirg air is supplied by the forced ventilation system with 100% of

Based on 750 MCOs

r/?- 2return air. Proposed air inlet temperature is 35°F. For comparison, inlet temperature of50°F is analysed as well. Maximum allowable temperature of the surface of a fuelelement is 100°F. Calculation is made for the maximum vault load of 320 kW at forforced ventilation system and maximum vault load of 270 kW for natural convection. Thedifference of these loads is due to additional heat load from structures at low supply airtemperature.

The purpose of this calculation is to find the maximum temperature of the surface of a fuelelement.

The highest temperature is expected at the fuel elements closed to the center of the MCO.Each fuel element is assumed as a solid uranium cylinders surrounded by water or air(Figure 2).

The diameter of the hollow outer element ring is assumed the same as the diameter of theouter zirconium cladding {identified as #17).

D17 « 6,1 cm « 2.4 in

The diameter of the inner cylinder of the outer element (identified as ft 14) is

DM = 4.4 cm = 1.7 in

Relative diameters for the inner hollow cylinder (Identified as #13 and #10) are:

D13 = 3.2 cm = 1.25 inD10 = 1.15 cm = 0.45 in

Relatively the thicknesses of uranium are

K«~ = 2 .4-1 .7 = 0.7 inA i fW = 1.25-0.45 = 0.3 in

The uranium cross-section is

The diameter of the equivalent by cross-section solid uranium cylinder is

The heat networking model is assumed with a number of zones of heat transfer.Considering a symmetrical heat transfer network the one-dimensional scheme is utilized inthe following Figure 1.

For zone C-M the heat transfer area is assumed as an average between 2 assemblies (2canisters, 28 elements) and MCO surfaces:

Transient Analysis

Description

The following study determines the heat transfer conditions after the loss of cooling air.The time duration will characterize the level of safety associated with the use of cooling airsystem.

The calculation is based on identification of changes in enthalpy between time periods.The difference between the sum of enthalpies for each material divided by the heat loadwill identify the time for reaching the particular temperature conditions.

Initial temperatures are assumed at airflow of 200,000 cfm flowing through 2 vaults fullyloaded with radioactive material. The total heat load is 320 kW.

Assumptions

1) The heat from nuclear decay during the loss of cooling airflow is considered to beabsorbed by fuel elements, cylinders, and assemblies filled with water, sleeves, andinternal air.

2) It is assumed that the total mass of each heat absorption material has the same averagetemperature.

3) It is assumed for conservative reasons that the sleeves loaded with 3.44 kW elementslocated at the end of the vault where the air temperatures are the highest.

4) It is assumed that the difference between temperatures of heat absorbing materials isproportional regardless the fact of the loosing cooling air.

CFD MODELING

The PHOENICS (Parabolic, Hyperbolic or Elliptic Numerical Integration Code Series) is acomputer program that simulates fluid flow, heat transfer, and other related phenomena.This simulation is based on mathematical derivation from established physical principles.The basic capabilities provided by PHOENICS include:

- menu driven interface-- one-, two-, or three-dimensional in Cartesian, cylindrical-polar or body fitted

coordinats-- steady-state or transient analysis-- single phase or two-phase media analysis-- compressible or incompressible flow- subsonic, supersonic or transonic flow

The PHOENICS solves the equations for flows, turbulence, mass and heat transfer by acontrol volume method based on finite element approach. In the present problem, the flowis mostly turbulent and also under buoyancy effect of natural convection. This problem isgoverned by the Navier-Stokes equations representing the conservation of mass,momentum and energy.

PHOENICS has many limitations and restrictions. First, the realism of its simulationscannot exceed that of the assumptions on which its use is based. Secondly, a simulationproduced by PHOENICS has an accuracy that depends upon the amount of computer timethat its user has been willing or able to spend. Finally, fluid dynamic phenomena beingwhat they are, it cannot be guaranteed that PHOENICS will provide a converged solution toevery problem without user's making special settings of solution-control switches.

CHAM company, the author of PHOENICS, stated that the code "is very well validatedand developed from over 10 years of commercial use (EasyFlow, release 2.01, page 1)."

There are a number of different simulations performed for this project using PHOENICS,including vault airflow and temperature distribution (CFD/Model), analyses of airflow

.around the building (Site Model), and study of entry device effect (T-Entry Inlet Model).

The details of PHOENICS simulation technique will be described using the CFD/Model.

Assumptions and Limitations

Finite volume method requires that the space be divided into discrete elements. Thehigh-.Vequency and spatially very small fluctuations of turbulent flow variables cannot bequantified directly. Assumptions must be made for these unknown turbulence correlations.The ;* ;st compromise between acceptable computer time and accuracy of the simulation ofturL- .nt flow phenomena is the k-c turbulent model, that consists of two additional

ntial equations for the turbulent kinetic energy (k) and the dissipation rate.


13

For all analyzed models flow in the vault under designed conditions are turbulent{Re > 3000).

Main Equations and Numerical Solution

Steady state turbulent flow in the vault can be described by conservation equations. Thegoverning equations can be written in terms of cartesian tensors.

Continuity equation:

where,u = component of mean velocity, m/sx » coordinates, mi, j » directions

Turbulent dissipation rate equation is:

For the inlet boundary conditions, the air velocity distribution componentis in z-direction.

The finite-domain technique, used by PHOENICS, combines the features of themethod of Patankar S.V. and Spalding D.B. {1972, "A Calculation Procedure forHeat, Mass and Momentum Transfer in Parabolic Flows," Int.J. Heat and MassTransfer, 21, London, England, 1565-1579}. The calculated space area isdiscretized into finite intervals and the variables are computed only at afinite number of locations called "grid-points." The variables are connectedwith each other by algebraic equations.

Internally, PHOENICS solves sets of algebraic equations that represent theconsequences of:

$ integrating the differential equations over the finite volume of acomputational cell over a finite time

$ approximating the resulting volume, area and time averages by way ofinterpolation assumptions

It is assumed that, in convection terms, all fluid properties are uniformover cell faces,- the timely new values are supposed to prevail throughout thetime interval.

For each dependent variable there are as many algebraic equations as thereare cells in the integration domain. Thus, there are a set of (NX x NY x NZ)algebraic equations for each dependent variable. PHOENICS solves them in aniterative manner, the object of which is to reduce the imbalance between theleft and right sides of every equation to a magnitude that is small enough tobe neglected. Iterations are needed because the equations, though linear inappearance, are non-linear in general. In each iteration cycle, thecoefficients and sources are assumed as constants. On the next iteration, thecoefficients and sources are updated from the latest values of the auxiliaryand dependent variables, and the linear equations reassembled and solved.Buoyancy sources are included in the appropriate momentum equation.

Modal Setup

Simulating a real problem requires to setup the model. This is one of themost important steps for obtaining a right solution. Necessary dimension ofthe problem has to be selected. It must be considered, that 3-dimensionalmodel with many regions o*:ten makes the solution of a problem very difficultbecause of increased running time and convergency problems. Therefore, ifrequirement to the accuta y is moderate, 2-dimensional model should.beselected. Symmetry in a adel can be efficiently utilized by reducing modelsize on symmetrical line' However, in many cases of fluid flow,nonsymmetrical airflow - tern must be selected even in a field that hasgeometrical symmetry. " example, airflow in a narrow cave with vertical


symmetry is nonsymmetric.PHOENICS allows to choose between 3 different coordinate options:

cartesian, cylindrical-polar, and body-fitted-

M«sh Generation

PHOENICS allows to generate a mesh automatically by specifying the gridfor each coordinate. Input of extents (sizes) and number of cells allowB tovisualize the geometry and make necessary correction prior to a run.Sensitive areas, where more accurate results are desired, need more cells.Also, distance between cells can be set as exponential function. This isoften used to get "closer look." to the areas where more accurate solution isnecessary.

Analysis Type, Properties, and Boundary Conditions

PHOENICS requires to specify the analysis type including hydraulic regime,heat transfer, flow regime (parabolic or elliptic), number of flow phases (oneor two), steady-state or transient analysis.

PHOENICS has a number of physical properties that must be selectedincluding density, laminar and turbulent viscosity, mixing-length, specificheat, and thermal conductivity.

Boundary conditions are the most important and complicated part of inputdata. They include inlets, outlets, walls, internal plates, obstructions,gravity, and heat sources. There is an opportunity to identify externalrelative pressure at outlet. Heat flux or temperature can be defined forwalls as well as for obstructions. Walls allow to calculate airflowresistance as well. One useful option is obstruction porosity between 0(solid) and 1 (fully open). Gravity force can be defined for buoyancycalculations, where the strength of buoyancy exists by using Bussinesqapproximation associated with reference temperature and expansion coefficient.Volumetric heat sources can be defined in several ways: from separate screen,as a part of obstructions entry, or as a part of walls entry. There is anindication received from CHAM of North America (PHOENICS's author, letter ofSeptember 3, 1991), that volumetric heat source used as input must be dividedby specific heat.

Solution Monitoring and Printout Control

PHOENICS has very extensive interactive capability for solution control.This control includes the initial value of dependent variables, termination ofthe calculations, relaxation of individual dependent variables, solutionoption for each dependent variable and the terms included in the equations.The program provides three different ways of under-relaxation: linear,automatic and false time-step. There is an opportunity to limit residuals byterminating the iterations for each dependent variable when residual value isreached.

During the calculation, converging process is monitored interactively (seeFig.A.51). Calculation can be interrupted any time and parameter type and/orthe value can be changed. A graph and a table of current values are shown forboth the hot area value and for the total residual for each variable. Goodconverging process is the one which shows that the upper plot stabilizesoscillations and the lower plot shows continuous decrease of residuals.

Color graphic results can be displayed by a post-processor using modulePHOTON. This program has its own Is iguage that: allows to display any cross-sections, variables, vectors in for*: of color fields and color vectors.

Program Verification and Validation

Verification and Validation proceou has been performed in accordance withDesign Control Procedures Manual tion 4 "Calculations", and section 9"Computer Code Validation and Veri ation"). Following steps are conducted;


-- Available CFD commercial programs were studied and the most efficient,that is PHOENICS, has been selected. The cover page of the program hasbeen signed by the Project Engineer and preapproved by WHC

-- The PHOENICS introductory course, given by CHAM of North America, wascompleted by the originator

-- Computer Code Summary has been filled. Project Classi-fication isassigned to Class IIIB "Off-the Shelf Design Aid-third party supported."Program validation includes: history of acceptance/ use and analysis of datain literature. As follow from the list of publications (see A.7.5.1)PHOENICS has been intensively checked and verified by many independentreviewers

-- Many sample test problems were run by the originator prior of using theprogram

-- A complete description of model is included into this report

- - The checked and the independent reviewer have verified that the modelis a reasonable representation of the process or physicalphenomenon of interest and outputs are reasonable.

Numerical evaluation including manual calculation has already been used andexplained for the AF/Model (see FDI calculation E350-HV-1802) . Similarevaluation for the CFD/Model is impossible due to a huge number of calculationand program complication. Logical way of verification includes data analyzingand referencing to respectable publications. Comparing to a similar programand/or to che tesc data are other ways for verificacion. However, we do notbelieve that similar data exist due to the unique configuration and conditionsof canister storage building. There are a number of similar programs, such asFLUENT, FIDAP, FLOTRAN. However, if the results of programs are different,there is no answer which program is correct, since there is no test data.Therefore, the most valuable sources to evaluate such a large system asPHOENICS are respectable publications for similar problems and engineeringjudgment from a highly qualified and experienced engineer.

As stated by CHAM of North America, PHOENICS is the industrie's first full-capability computational fluid dynamics software package for PC. There areover 350 installation of PHOENICS throughout the world. PHOENICS referencesincludes a list of publications that shows large number of applications wherePHOENICS has been successfully used for solving many fluid mechanics and heattransfer problems.

Figure AlSa

Inlet air opening is located at the upper-left part of the model. Outletopening is located at the upper-right part of the model. The middle part ofthe vault is occupied by sleeves. Airflow pressure loss in this part of thevault is simulated by using porosity factor. PHOENICS is not capable ofsimulating anisotropic porosity that would have some advantages for thespecific air flow pattern of space occupied by sleeves. Airflow regime isturbulent since, for maximum loads, Reynolds number is above 3000. Wallsurfaces are assumed adiabatic (conservative approach), however hydraulicresistances of walls are taken into consideration. Because of assumptionssuch as 2-dimensional simulation and porosity, temperatures in this simulationwill be used as relative values only. The results of simulation will allow tocalculate flow pattern in the vault and discover hot areas where temperaturesare higher due to the buoyancy effect. The reference air temperatures are atinlet and/or outlet. All dimensions used in PHOENICS are in SI units.

For the model under consideration cartesian grid is selected. This gridconsists of cells formed by intersection of planes of constant z and planes ofconstant y. A rectangular grid was constructed using interactive preprocessorEasyFlow. Y-direction is divided into 6 regions with physical dimensionsshown on Figure 7. Each region has been divided into different number ofcells. Z-direction is divided into 3 regions with equal spacing betweencells.

Properties

Air density and laminar viscosity are assumed to be 1.01 kg/m3 and 2.1E-5mJ/s respectively. Turbulent viscosity is calculated by the program itself aswell as the mixing length. Air specific heat is 1004 }/>.g-°C and air thermalconductivity is 0.0263 w/m-"C. There is no need of using variable propertiessince the buoyancy effect is calculated by Bussinesq approximation with airexpansion coefficient.

Boundary Condition*

Boundary conditions include: one inlet, one outlet,gravity, and heat sources.

Inlet is located in the HIGH face Z-region #3, Y-r.-,of S3,000 cfm, inlet velocity is calculated for 2 vaul

-m- isV - (6x<gJl?g) (2/3) " 77-

where:6x(8x2l.5) is the total air entry area for 3 vaults, ft2

The direction of air at inlet opening is -Z (see Fig.7). Turbulent intensityis recommended by PHOENICS (see EasyFlow manual, p.6-84) as 2% or 0.02. Inletair temperature assumed is 115°F • 46.06°C. Outlet and wall boundaries andobstructions are as shown in Fig.7. Since we are using constant density andconsidering buoyancy effect, Bussinesq approximation has been input. Forreference temperature of 25®C the air volume expansion coefficient ispaO.Ot^G'C1. This coefficient is the reciprocal of the absolute temperaturefor an ideal gas or 1/(273+25)•0.00336°C"1 (see PHOENICS EasyFlow Manual, p.6-96). Gravity acceleration is taken for negative Z-direction as -9.81 m/s2.

Effective vault volume is calculated as

Vol. • 96 x 36 x (3 x 50) • 518,400 ft3 - 14,679 m1.

Vault volume occupied by sleeves (3 vaults) is

Vol3 = 22 rows x 10 columns x 3 vaults x K/4 x 3! x 36 . 167,949 ft3 = 4755 m3

Volumetric heat flux is calculated as energy divided by volume and byspecific heat considering only 2 vaults:

w . S 270 x 1000 , , ;Wv " (Vol . ) C p " 14679 x 2 / 3 X 1004 " ° * 2 7 5 W / m

where:270 is total decay energy dissipated from canisters in Kw, and1004 is air specific heat in j/kg-°C.

Airflow resistance of the vault is simulated as porosity. Porositycoefficient is calculated as following expression (the same for 2 vaults with440 sleeves as for 3 vaults with 660 sleeves)

1 - Vol./Vol. = 1 - 167,949/518,400 » 0.67

-Interpretation of Results

The results of PHOENICS modeling are presented in Figures 8 through 13.

Mostly convergency residuals are decreasing. Temperature in Hot Area valueplot is increasing by 0.007* only.

On the right side of the screen the scale of temperatures is displayed. It iseasy to find temperature in a region starting from the white cell .see 53degree). Temperature fields show that higher air temperatures are in a widearea below the ceiling. Velocity vectors and thermal regions are t-hown onFig.14.

There are four major flow regions:

Region 1. The beginning of the stream where entered air is me .ig downcreating first entry vertex


Region 2. Lower stream moving in the direction from inlet to outlet.This stream contains relatively low air temperatures. It coolsexternal walls and floor

Region 3. Higher stream that consists two substreatms. These substreamsstart about 1/4 to the end of the vault but one of them moves toinlet and the second one moves to the outlet. Air inthis region is the hottest in the vault.

Region 4. Second vertex located below the vault outlet opening.

Air buoyancy and slower air movement in the third flow region createhigher temperatures at the top of the vault called "Hot Pillow" or "Hot Area."To know actual air temperature in "Hot Area" is important for calculatingsurface temperature of the ceiling. The 2-dimensional simulation showsinternal air temperatures at each cell including temperatures of inlet andoutlet air. There is a difference between the outlet and the "Hot Area" airtemperatures due to the buoyancy- The calculation of the hottest airtemperature in the vault is evaluated by adding this temperature difference tothe outlet temperature, calculated by the AF/Model. The new air temperatureis called "Hot Area air temperature in the vault."

Calculations show maximum "Hot Area" temperature differences betweenoutlet area of 9°F(5°C). The maximum air temperature is 57°F(13S°C).

If a solid cylinder is immersed in a fluid at a specified temperature Tv andthe convection heat transfer coefficient at the surface is specified and denoted byhn the surface terr.perature at ra is not known a priori.

This useful relationship gives a rough idea of the ipectral energydistribution from a black surface; 257* of the energy :is radiatedat wavelengths shorter than the maximum, and 7.17a is radiatedat wavelengths longer than the maximum.

Actual Radiation

Substances and surfaces diverge variously from the Stefan-Bolumann and Planck Laws. Wb and WH are the maximumemissive powers at a surface temperature. Actual surfaces emit andabsorb less readily and are called nonbtack. The emissive powerof a nonblack surface, at temperature T, radiating to thehemispherical region above it is written as:

W m tWb~ tqT* (36)where c is called the hemispherical emittance. The term emittanceconforms to physical and electrical terminology; the suffix "ance"denotes a property of a piece of material as it exists. The ending"ivity" denotes a property of the bulk material independent ofgeometry or surface condition. Thus, eraittance, reflectance, ab-sorptance, and transmittance refer to actual pieces of material.Emissivity, reflectivity, absorptivity, and transmissivity refer toproperties of materials which are optically smooth and thickenough to be opaque.

The emittance is a function of the material, the condition of itssurface, and the temperature of the surface. Table 3 lists selectedvalues; Siegel and Howell (1981) have more extensive lists.

The monochromatic emissive power of a nonblack surface issimilarly written as:

tx(Cxk-i/eci'lT- I) (37)

where e, is the monochromatic hemispherical emittance. Therelationship between t and ct is given by:

If tL does not depend on A, then, from Equation (38), t - £t.Surfaces with this characteristic are called gray. Gray-surfacecharacteristics are often assumed in calculations. Several classesof surfaces approximate this condition in some regions of the spec-

tmm. The simplicity is desirable, but care must be exercised,especially if temperatures are high. Assumption of grayness issometimes made, because of the absence of information relatingi a n d A

When radiant enej-gy falls on a surface, it can be absorbed,reflected or transmitted through the material. Therefore, from theFirst Law of Thermodynamics:

a + T + Q « 1 (39)

where« • fraction of incident radiation absorbed or absorptanctT - fraction of incident radiation transmitted or (ransmitfanceQ - fraction of incident radiation reflected or reflectance

If the material is opaque, as most solids are in the infrared, T - 0and a + c • 1. For a black surface, a - I, Q • 0 and T - 0.Platinum black and gold black have absorptances of about 98%in the infrared, which is as black as any actual surface is. Anydesired degree of blackness can be simulated by a small hole in alarge enclosure. Consider a ray of radiant energy entering theopening. It will undergo many internal reflections and be almostcompletely absorbed before it has a reasonable probability of pass-ing back out the opening.

Certain flat black paints also exhibit emittances of 98ô overa wide range of conditions. They provide a much more durablesurface than gold or platinum black and are frequently used onradiation instruments and as standard reference in emittance orreflectance measurements.

Kirthhoffs law, relating emittance and absorptance of any opa-que surface from thermodynamic considerations, states that forany surface where the incident radiation is independent of angleor where the surface is diffuse, cx * ak. If the surface is gray, orthe incident radiation is from a black surface at the same temper-ature, then also c m a, but many surfaces are not gray. For mostsurfaces listed in Table 3, absorptance for solar radiation is dif-ferent than emittance for low temperature level radiation. This isbecause the wavelength distributions are different in the two cases,and £t varies with wavelength.

The foregoing discussion relates to total hemispherical radia-tion from surfaces. Energy distribution over the hemisphericalregion above the surface also has an important effect on the rateof heat transfer in various geometric arrangements.

laboratory test conditions. Air gaps in ihese types of iiisuationsystems can seriously degrade thermal performance as a result ofair movement due to both natural and forced convection. Sabineetal. (1975) found the tabular values are not necessarily additivefor multiple-layer, low-cmittance airspaces, and tests on actualconstructions should be conducted to accurately determine ther-mal resistance values.

Values for foil insulation products supplied by manufacturersmust also be used with caution because they apply only to systemsthat are identical to the configuration in which the product wastested. In addition, surface oxidation, dust accumulation, andother factors that change the condition of the low-cmittance sur-face can reduce the thermal effectiveness of these insulationsystems. Deterioration results from contaa with several types ofsolutions, either acidic or- basic (eg., wet cement mortar or thepreservatives found in decay-resistant lumber). Polluted en-vironments may cause rapid and severe material degradation.However, site inspections show a predominance of well-preservedinstallations and only a small number of cases in which rapid andsevere deterioration has occurred.

CALCULATING OVERALL THERMALRESISTANCES

Relatively small conductive elements within an insulating layeror thermal bridges can substantially reduce the average thermalresistance of a component. Examples include wood and metalstuds in frame walls, concrete webs in concrete masonry walls, andmetal ties or other elements in insulated wall panels. The follow-ing examples illustrate how to calculate R-values and U-factors forcomponents containing thermal bridges.

The following conditions are assumed in calculating the designR-values:(1) Equilibrium or steady-state heat transfer, disregarding effects

Wood Frame Walls

The average overall R-vaiues and U-faaors of wood frame wallscan be calculated by assuming parallel heat flow paths throughareas with different thermal resistances. Equations (1) through (5)from Chapter 20 are used.

For simple stud wails 16 in. on center (OC). the fraction of fram-ing is assumed to be approximately 0.15; for studs 24 in. OC, ap-proximately 0.12. These fractions contain an allowance for multi-ple studs, plates, sills, and extra framing around windows anddoors but do not allow for headers or band joists.

Example J. Calculate the U-factor of the 2 by 4 stud wall shown in Figure2. The studs are ai 16 in. OC. There is a 3.5- in. mineral fiber ban insula-tion (R-ll) in the stud space.

* McAdams (1954) recommends this equation for heating and cooling. ° h' is expressed in Btu/h• ft2 T initial temperature difference.Other authors recommend an exponent of 0.4 for heating and 0.3 for e Cmu is based on minimum free area. Coefficients for tube banks de-cooling, pend greatly on geometrical details. These values approximate only.

The characteristic length, D.is the diameter of the tubeôutside•ffrTnside, or the length of the plane plate. For other shapes, thehydraulic diameter, Df, is used, where:

This reduces to twice the distance between surfaces for parallelplates or an annulus.

Techniques to Augment Forced Convection

TUrbulence promoters in smooth flow passages, such as coil-ed wires, twisted tapes, discs, baffles, configurated surfaces, andpacking, increase forced convection heat transfer coefficients forsingle- and two-phase flows. Pumping power is usually increas-ed relative to that of smooth surfaces, the amount depending onthe device.

Techniques applied to commercial heat exchange equipment toimprove heat transfer to flow inside of tubes, usually at the expenseof pumping power or external power applied to the system, in-clude: (I) surface promoters, (2) displaced promoters, (3) vortexflows, (4) surface vibration, (5) fluid vibration, and (6) electrostaticfields. Methods requiring external power (items 4,5, and 6) are dif-ficult to apply to large-scale heat exchange equipment, and infor-mation on increased equipment cost and power requirements is

lacking. Of the methods requiring no external power (items 1, 2,and 3), displaced promoters are difficult to install inside tubes, andgenerally have large friction factors; surface promoters and vortexflow appear most suited for commercial use. Surface promotersrange from selective finishing of the surface to increasing surfacearea by adding fins.

EXTENDED SURFACE

Heat transfer from a prime surface can be increased by at-laching/ins or extended surfaces, to increase the area available forheat transfer. Fins provide a more compact heat exchanger withlower material costs for a given performance. To achieve optimumdesign, fins are generally located on the side of the heat exchangerwhere the heat transfer coefficients are low (such as the air sideof an air-to-water coil). Equipment with extended surface includesnatural and forced convection coils and shell-and-tube evaporatorsand condensers. Fins are also used inside tubes in condensers anddry expansion evaporators.

Fin Efficiency

As heat flows from the root of a fin to its tip, temperature dropsbecause of the thermai resistance of the fin material. The temper-ature difference between the fin and the surrounding fluid istherefore greater at the root than at the tip, causing a correspon-ding variation in the heat flux. Therefore, increases in fin lengthresult in proportionately less additional heat transfer. To account
