BLANKET SAFETY ANALYSES FOR LOCA Date: 07/1 4198(CASE 3: EXTERNAL HR BREAK AT PUMP OUTLET WITHOUTPUMP TRIP) ?Zige: . 1 of 20

1 IntroductionThis report is one of a series of reports that document normal operation and accidentsimulations for the Accelerator Production of Tritium (APT) blanket heat removal (HR)system [1-7]. These simulations were performed for the Preliminary Safety AnalysisReport. The results of simulations of a large break LOCA in the of the primary heatremoval system piping, between the pump discharges and the heat exchanger inlets,are herein documented. The accident simulations were performed, using TRAC tomodel transient behavior of the heat removal system, and FLOWTRAN-TF, a computercode developed at the Savannah River Technology Center, to model detailed transientbehavior in a blanket module.

2 TRAC I-D System ModelThe TRAC model of the blanket heat removal system is described in detail in Ref. [8]. Itis an integrated one-dimensional system model that contains all major components,systems, and heat structures necessary to simulate transient system behavior for a widerange of accident conditions. Reference [3] also contains background information aboutmodeling philosophy used in the development of this model. Table 2-1 summarizesmodule description, thermal deposited power, and connection pipe size of each of the 6bla,nket modules as modeled in the one-dimensional lumped a~proach.

2.1 Scenario DescriptionA large break LOCA external to the cavity is a design basis accident. The residual heatremoval (RHR) system must be able to mitigate the accident and maintain adequatecoolant flow to the blanket modules. The mitigation systems are designed with sufficientredundancy that the worst single failure does not disable the entire system. For theRHR system, this means that one of two loops can still function.

The break location, for Case 3, is in the section of 16 inch pipe between the pumpdischarge combining Tee and the heat exchanger inlet dividing Tee, as shown in Fig.2.1-4. This is a 3.6 m long straight section of pipe through which all of the primary HRflow passes. A double-ended guillotine break (DEGB) is assumed. Following the breakoccurrence, the system will rapidly depressurize. Power to the beam will be cut, andthe RHR pump will be started and reach full speed in about 15 seconds. Power to theHR pumps is not cut in this accident scenario. This accident scenario differs from that inCase 2 [4] only in that the HR pumps are not tripped.

2.2 Model Upgrades

Component action tables for the BREAK and VALVE components are updated for theCase 3 accident simulation. .Component action tables for HR and RHR check valves arebased on S-shaped forcing function values [8]. Constrained steady-state (CSS)capabilities are added to the TRAC normal operation system model. Signal variablesand trip signals of the system model are also updated by using the control procedure forthe Case 3 accident scenario described in Ref. [8].

2.3 Initial ConditionsThe initial conditions for this TRAC simulation are steady-state normal operating (NO)conditions, described in Ref. [1]. Table A-2 lists the NO values of key parameters.

2.4 Transient Boundary Conditions

To initiate the LOCA, the steady-state TRAC run was restarted in transient mode with aone-cell PIPE component (component 37) replaced with two BREAK components(pressure boundary conditions) to produce a 200% double guillotine break. Figure A-1is a TRAC component layout of the HR loop external to the cavity vessel, and PIPEcomponent 37 is shaded to indicate that it occupies a potential break location. TheTRAC layout in Fig. A-1 is modified by connecting PIPE components 36 and 38 toBREAK components, with junctions J37 and J38. This location for an external breakwas chosen because it is the location in the HR loop with the highest NO pressure,through which all of the HR flow passes.

The BREAK components were set to ramp from the steady-state pre-incident pressureto atmospheric pressure in 0.1 seconds. In addition to adding the BREAK componentsto the TRAC system model, the pressurizer boundary condition was changed from aBREAK (constant pressure boundary condition) to a zero FILL (no flow) boundaty. Thepressure control system for the pressurizer will be designed to preclude attempts toadjust the pressure during a severe transient, and the no flow boundary condition isconsistent with this constraint.

2.5 Trips and Controls

The power to the beam is tripped 0.2 seconds after the pressure in the pressurizersurge line drops 5% from the NO value of 0.72363 MPa (105 psia) to 0.68745 MPa(99.7 psia). The elapsed time for the pressurizer surge line pressure to reach this setpoint is about 0.1 seconds. The delay time between reaching a setpoint and trippingthe beam is dominated by the response time of the transducers. A comparison withsimilar transducers in reactor systems put this response time at about 0.1 seconds. Thedelay time chosen for simulations was obtained by doubling the estimated responsetime for the transducers, to produce what is believed to be a conservative value. Thebeam trip is simulated by changing the steady-state power in the heated structures to atime-dependent decay power curve. Figure 2.5-1 shows this decay curve. The RHRpump is activated, without delay, when the pressurizer surge line pressure drops 5Y0.

The RHR pump is modeled to attain full speed (94.35 rad/see) within 15 seconds afterthe accident, by using the component action table with S-shaped forcing function values[8]. Check valves on the discharge sides of the HR and RHR pumps are actuated, toavoid flow reversals, immediately after initiation of the LOCA. If a flow reversal occurs,HR and RHR check valves are set to close immediately. Table 2.5-1 lists all of the tripsignals and controls used for this accident simulation. The HR pump trip is disabled bysetting the delay time to 10,000 seconds. This is never reached in a 600 secondaccident simulation.

2.6 TRAC VersionThis transient model was run using TRAC-PFl/MOD2 version 5.4.28a [14]. A modifiedversion of TRAC to generate graphics files was employed [9]. Light water properties

component, and briefly describes each component In the TRAC model. These figuresand the table are used to interpret the graphical results. The figures in Appendix Bshow transient results of the TRAC simulation. They are divided into three groups:results for the PLENUM components (Figs. B-1a through B-7d), results for the PIPE,VALVE, and PUMP components (Figs. B-8a through B-25e), and results for the HEATSTRUCTURE components (Figs. B-26 through B-42). The legend for each figure liststhe component and cell numbers for the results shown. The component numbers arethe TRAC system model component numbers that are shown in the component layoutfigures.

The simulation results show that the pressurizerand a single RHRsystem can mitigatethis design basis accident without any damage to the blanket module system andstructure. During the initial 600 seconds of the accident, the liquid in the pressurizerdoes not drain completely. The temperature of the coolant water flowing through theblanket modules does not reach saturation, consequently there is no boiling. Transientphenomena in the key blanket component systems are described in detail in thefollowing subsections.

3.1 ModulesFigure A-1 is the TRAC component layout for the six modules and the associated pipingnetwork below the two fixed headers. Figures B-1a through B-1 d show respectively thepressures, temperatures, liquid subcooling temperatures, and void fractions for the twoPLENUM components 380 and 340, that respectively represent the fixed inlet and outletheaders. There is a rapid depressurization of both headers after initiation of theaccident sequence, and a transient response ensues for approximately 240 seconds.Thereafter, the pressures remain essentially constant at approximately 21 psia. Theoutlet header temperature drops approximately by 16 C to 42 C during the initial 150seconds, and thereafter remains essentially constant. After 600 seconds, thetemperature difference between the @o fixed headers is less than 1 C. The inlet headerstarts to void after 60 seconds, and the outlet header starts after 110 seconds. The voidfractions are due to entrained air, and the peak values for the inlet and outlet headersare respectively 0.5 and 0.4. After 240 seconds the void fractions drop to zero for theoutlet header and approximately 0.1 for the inlet header.

Figures B-2a through- B-2d show respectively the pressures, temperatures, liquidsubcooling temperatures, and void fractions for the three PLENUM components thatrepresent the inlet (comp. 370), middle (comp. 350), and outlet (comp. 370) plenums formodule #1. The transient pressure profiles are similar to those of the fixed headers.The outlet plenum fluid temperature drops quickly during the initial 50 seconds to 44 C.Over the next 250 seconds, it dips to 41 C and returns to 42 C. Over the last 300seconds of the simulation, the outlet plenum temperature rises slowly to 43 C. After 600seconds, the temperature rise in the flow across module #1 is approximately 1 C.Between 70 and 260 seconds of elapsed time, there is significant void in the threemodule #1 headers. The void drops to 0.1 in the inlet plenum and zero in the middleand outlet plenums for the balance of the simulation. The rest of the module plenumsexhibit similar behavior.

Figures B-18a through B-18e show pressures, fluid temperatures, subcoolingtemperatures, mass flowrates, and void fractions in the first, middle, and last cells of theupflow region of module #1 (comp. 300). The pressures and temperatures are very

similar to those of the module headers. The mass flowrate through the module dropsvery quickly from a pre-incident value of 545 kgh to approximately 230 kg/s, and isclose to constant for approximately 80 seconds. In the next 100 seconds, the flowratedrops to approximately 15 kg/s and holds essentially constant for the duration of thesimulation. The mass flowrates through the rest of the modules behave in a similarfashion.

Figures B-26 through B-31 show the maximum metal temperatures, in the bottom andtop cells, of the HEAT STRUCTURE components associated with the up flow regions ofthe six lumped modules. Figures B-32 through B-37 show the heat structure surfacetemperatures at the same cell locations. After 600 seconds, all temperatures are lessthan 50 C.

3.2 HR Loop and Pressurizer

Figure A-4 is the TRAC component layout for the section of the primary heat removalloop that is between the fixed headers and external to the cavity vessel, and Fig. A-6 isthe component layout for the pressurizer and the surge line.

Figures B-8a through B-8e show pressures, fluid temperatures, subcoolingtemperatures, mass flowrates, and void fractions in several locations in the HR pipingbetween the outlet header and the dividing Tee that splits the flow for the two pumps.The pressure transient in the hot-leg HR piping is similar to that in the fixed outletheader. The pressure in cell 7 of component 22 drops very quickly to approximately 2psia, and remains essentially constant for 110 seconds. Between 110 and 240 seconds,the pressure increases to atmospheric, and thereafter is fairly constant. The massflowrate drops very quickly from 1569 to 600 kg/s and remains constant forapproximately 70 seconds. Between 70 and 190 seconds the mass flowrate in the HRhot-leg pipe drops to zero. Commencing at 110 seconds, air is entrained in the HR hot-leg flow. When the flow stagnates at 190 seconds, the void fractions are respectively0.9 and 0.3 in components 22 and 26. Thereafter the air/water mixture in the pipestratifies, and the void fraction in component 22 increases to 1.0. The void fraction incomponent26 drops to zero. Component 22 is a high point in the hot-leg pipe.

Figures B-9a through B-9e show the flow variables on the suction and discharge sidesof pump 1, and Figs. B-1 Oa through B-1Oe show the flow variables on the suction anddischarge sides of pump 2. The behaviors of both pumps are qualitatively similar. Thepump suction pressures drop very quickly to approximately 2 psia, and the pumpscavitate for approximately 120 seconds. Both pump suction void fractions areapproximately 0.65. After 120 seconds, entrained air circulating through the HR loopreaches the hot-leg pipe and voids the section of pipe upstream of the pumps. Theflowrates drop to zero as the remaining water in the pump suction legs is pumped outthe break. By 170 seconds, the flowrates through both pumps are zero.

Figures B-12a through B-12e show the flow variables at the heat exchanger inlets.When the break occurs, the flow reverses, and the fluid drains out of the heatexchanger inlet piping in approximately 20 seconds. Figures B-13a through B-14e showthe flow variables in the heat exchanger outlets and the cold-leg piping of the HRsystem. This piping is lower than the break, so it does not drain out the break. Theheat exchanger outlets drain to the fixed inlet header and empty in 100 seconds.Reverse flows in the cold-leg pipe and heat exchanger outlets, from the fixed inletheader,are establishedat 220 seconds,and continuefor the durationof the simulation.

Figures B-1 5a through B-15e show pressures, fluid temperatures, subcoolingtemperatures, mass flowrates, and void fractions in the bottom cell of the pressurizerand in the surge line, close to the inlet header. The pressurizer flow into the fixed inletheader goes to 280 kgk very quickly, and then drops slowly to approximately 13 kgls atthe end of the simulation. This flow maintains the inlet header pressure atapproximately 19 psia, after the initial 240 seconds of the transient.

3.3 RHR LOOP

Figure A-5 is the TRAC component layout for the residual heat removal system. Thispipe network goes from the fixed outlet header to the fixed inlet header, in parallel withthe part of the primary HR system that is external to the cavity. The RHR pump startswhen the beam is tripped, and takes 15 seconds to reach full speed. Figures B-16athrough B-1 6e show the values of the flow variables on both the suction and dischargesides of the RHR pump. The check valve opens and flow commences approximately 10seconds after initiation of the accident. The mass flowrate increases from zero to 48kgh very quickly, and remains steady for approximately 40 seconds. From 60 to 120seconds, the pump cavitates and the flowrate drops to 25 kgls. After the cavitationstops, the flowrate quickly increases to 54 kg/s, and subsequently, quickly drops to zeroflow, as air from the fixed outlet header voids the RHRpump suction pipe. Between220and 400 seconds, the RHR flow increasesfrom zero to 62 kg/s, as the void fraction inthe fixed outlet header decreases to zero and the RHR pump suction pipe refills. 62kg/s is approximately 4% of the normal HR flow. Figures B-1 7a through B-1 7e show theflow variables on the inlet and exit sides of the heat exchanger. By 300 seconds, theheat exchanger outlet temperature has decreased to 42 C, and it is steady thereafter.At the end of the simulation,the temperaturedrop across the heat exchangeris 0.6 C.

3.4 Cavity Vessel and Flood System

The cavity vessel flood system and heat transfer connections between blanket modulesand the cavity vessel are shown in Figs. A-2 and A-3, respectively. The cavity vesselflood system is not activated for external LOCA’S, and this part of the TRAC systemmodel does not influence the results of this simulation.

4 FLOWTRAN-TF Detailed Bin Model

The basic FLOWTRAN-TF model is described in Refs. [1O & 13] and was used in thisversion for the LOCA Case 3 analyses. The FLOWTRAN-TF model was developed tosimulate the thermal-hydraulic conditions in a lateral Row 1 blanket module using thereference1 plate-typedesign [15]. The areal mesh of the bin model is shown in Figure4-1 along with the location and indexing used for the 12 discrete flow channels.

4.1 Model Upgrades

No modifications to the original model were required to for the LOCA Case 3 analysis.

4.2 Initial Conditions

Initial conditions for all of the flow transients are the normal operating conditionsreported in Ref. [1]. The TRAC supplied initial conditions used in the FLOWTRAN-TFcalculations are listed in Table 4.2-1.

4.3 Transient Boundary Conditions

Results from the TRAC external large-break LOCA transient were used to supplyboundary conditions to the FLOWTRAN-TF code for detailed calculations of thethermal-hydraulic behavior of a single row-1 blanket plate. The TRAC transient resultsused in these calculations were:

1. Total coolantflow to the lateral row-1 blanket module taken from TRAC PIPEcomponent 454.

2. Inlet cooling water temperature, pressure and void fraction taken from TRACPLENUM component 350. The calculations used inlet flow as an appliedboundary condition and inlet pressure was used only for physical propertyevaluations.

3. Outlet pressure taken from TRAC PLENUM component 33o.

Inlet conditions derived from the TRAC system analysis are ‘shown in Fig. 4.3-1 wherethe boundary conditions are plotted as transient values relative to the pre-incidentconditions. The pre-incident flow to a single blanket plate is taken to be 1.488 kgh.Since void fraction naturally falls between zero and one, absolute values of void fractionare plotted in the figure.

FLOWTRAN-TFBin Model Results

A listing of the input deck used for the FLOWTRAN-TF calculations of LOCA Case 3 isgiven in Appendix E. Some results from the FLOWTRAN-TF calculations are shown inFig. 5-1 where the maximum aluminum temperature found anywhere in the platecladding is plotted as a function of time into the loss-of-coolant accident transient. Theinitial maximum temperature of 100.0 C is indicated on the ordinate since it is difficult tosee the sudden temperature decrease that occurs within the first few seconds on thetransients. Initially, the maximum aluminum temperature occurs on the side of the platenearest the decoupler region and closest to the point of beam impact. It is assumedthat the power is tripped 1.0 second after the start of the accident and that the pre-incident power is the nominal value 61.5 kW.

It is clear from the metal temperatures shown in Fig. 5-1 that surface temperatures inthe flow channels following beam trip are not close to local boiling conditions. To furtherillustrate the safety margins, operating surface heat fluxes (q~hf) were compared to theheat fluxes predicted for onset of nucleate boiling (qOn~), onset of significant voidformation (qOW)and the critical heat flux (qC~f). Since each of the 12 flow channels has20 axial cells and at each axial level the surface is composed of from 8 to 17 surfacenodes there are many (2760) surface heat fluxes at any time in the calculation. Toreduce the number of data points, we have taken the approach of reporting themaximum heat flux at each axial position within each channel irrespective of theparticular surface node where the maximum occurs. Further we can restrict the

examination to the location of the peak axial heat fluxes. The axial power shape for theblanket module is shown in Fig. 5-2 along with the 20 cells that were used to discretizethe axial dimension for the safety calculations. Highest operating surface heat fluxeswere observed to occur in axial cells 10 through 15.

To show some representative results, the operating surface heat flux and the calculatedlimits for Case 3 are shown in Figs. 5-3 through 5-5 for all of the flow channels at axiallevel 11. Channels 1 and 5 are the rectangular flow channels nearest the decouplerside of the plate while channel 8 is the first annular flow channel on that side. This sideof the plate absorbs the largest fraction of the deposited power but has a larger fractionof the coolant flow. Channels 4 and 7 are the rectangular flow channels nearest thecavity side of the plate where deposited power and coolant flow are lowest.

Results from other axial locations on the plate surface are similar demonstrating asubstantial margin between the surface heat flux and the potentially limiting values. Theclosest approach of the operating heat flux to the limiting values typically occurs in flowchannels 1 or 8 between O and 2 seconds into the transients. Near the top of the pIate,the surface heat flux can even reverse as energy flows from the heated water back intothe cooler metal. This condition was observed in the annular flow channels and in someof the low power rectangular channels.

6 Conclusions

6.1 Comparison to Thermal/Hydraulic Design Criteria

Simulations performed using the TRAC system model and the FLOWTRAN-TF detailedbin model show that the APT blanket modules maintain a coolable geometty during theLOCA Case 3 scenario. The thermallhydraulic (T/H) design criteria, along with the basisfor their development, is discussed in Refs. [11,12]. For LOCA the T/H onset criteria arebased on meeting very strict phenomenological limits with a high degree of confidence,as follows:

- for local heated surfaces within the module components, the onset-of-significant-voids [OSVJ) at a three sigma confidence level; and

- for the remaining unheated piping sections of the blanket system, the onset-of-bulk-boiling [OBB]) at a three sigma confidence level.

Additional (steady-state derived) material design criteria are imposed on the maximumlead and aluminum (Series 6061 - Type T6) metal temperatures acceptable for themodule components. The limiting values for these parameters are 327.5 C and 115 Cfor lead and aluminum, respectively. These material design criteria ensure that acoolable geometry can be maintained throughout the expected lifetime of each moduleunit.

On a module-by-module basis, the above steady-state material and thermal onsetcriteria for LOCA are compared to the FLOWTRAN-TF detailed bin model results. Thebin model results for the reference 1 plate-type module are tabulated in Table 6.1-1(note that only module #1 results are currently available since the design specificationsfor modules #2 through #6 do not presently exist). However, module #1 should be closeto the most limiting module. Additional thermal onset criteria, which are typicallyconsidered, are also provided in Table 6.1-1. Note that these are generally morestringent than the imposed design criteria chosen.

The definitions of the criteria ratios in Table 6.1-1 are listed below, as follows:

Tw..................wall temperature

To evaluate these criteria, the maximum value corresponds to its limit spatially, as wellas over the time period of the event sequence. The ratio of OHF-to-CHF is sometimesreferred to.as the departure from nucleate boiling ratio [DNBR]. Predicted thermal onsetratios should not exceed unity.

Confidence bounds are required to establish the acceptable level of probability ofexceeding these criteria. The results presented in Table 6.1-1 represent best estimatevalues (i.e., all input parameters were set to their best estimatevalues). Quantificationof overall uncertainties and then their corresponding confidence levels (i.e., operatingand modeling uncertainties) have not yet been performed. Future efforts to perform aresponse surface analysis are planned. At that time quantification of safety margins willbe determined.

The peak blanket metal temperature occurs in module #1, and it is 112.8 C, aspredicted by the FLOWTRAN-TF model. This occurs in the lead plate, and it is wellbelow the lead melting point, 327.5 C. The peak aluminum temperature also occurs inmodule #1, and it is 100 C, below the long term temperature limit of 115 C. Since thepower decay is steeper than the flow decay the reported maximum metal temperaturesare essentially the pre-incident values. Actually, maximum temperatures are reached 1second after the start of the accident when the beam trips. However, the thermal inertiaof the solid is such that this brief time delay is negligible.

6.2 Design Issues

The TRAC system model predicts a peak lead temperature in module #1 of 152 C andthe detailed FLOWTRAN-TF bin model predicts a peak lead temperature of 112.8 C.The cruciform design was used in the TRAC system model, and the plate design wasused in the FLOWTRAN-TF model. This points out the need for consistency betweenthe two models. The TRAC model will be upgraded in order to provide this consistency.

6.3 Predicted Impact

Blanket conditions during LOCA Case 3 fail within all specified thermal/hydrauIic designcriteria. No off-site impact to people or the environment would occur as a result ofLOCA Case 3. The only on-site consequence would result from the release ofcontaminated cooling water.
