EXECUTIVE SUMMARY

Information for five retrieval campaigns was reviewed and events which caused either retrieval

shut-down or delay were noted by equipment type. Once documented, the findings were

evaluated to identify areas with repeated events. The information was obtained from the

Retrieval and Closure Operational Engineer Log Books, the Base Operations Log Books, the

retrieval completion reports, and the notes recorded by the Process Engineers in the material

balance calculation spreadsheets. Several hundred Problem Evaluation Requests, also known as

PERS, were reviewed and determined to not provide new pertinent information. The Document

Management Control System database was searched for lessons learned reports. No lessons

learned reports were found for the campaigns being evaluated.

There have been three distinct types of retrieval systems used in 241-C Tank Farm retrieval

efforts: the Modified Sluicing Waste Retrieval System, the Mobile Arm Retrieval System –

Sluicing, and Mobile Arm Retrieval System – Vacuum. The campaigns evaluated in this report

used either the Waste Retrieval System or the Mobile Arm Retrieval System – Sluicing. The

five campaigns evaluated are the 241-C-101 bulk retrieval campaign the 241-C-107 retrieval

campaign, 241-C-111 bulk retrieval campaign, the 241-C-112 bulk retrieval campaign, and

241-C-112 hard heel retrieval campaign.

A total of 487 events occurring over 390 operating days were documented. These events were

sorted into a number of categories as detailed in Section 3.0, “Methodology.” Analysis of these

events resulted in nine specific recommendations for areas needing improvement or further

review, as detailed in Section 5.0, “Recommendations.”

1.0 INTRODUCTION

This document reviews information for five bulk and hard heel retrieval (HHR) campaigns to

identify areas for equipment and operational process improvement. The evaluation addresses

both equipment reliability and availability.

2.0 SCOPE

Information for five retrieval campaigns was reviewed and events which caused either retrieval

shut-down or delay were noted by equipment type. Once documented, the findings were

evaluated to identify areas with repeated events. The information was obtained from the

Retrieval and Closure Operational Engineer (OE) Log Books, the Base Operations Log Books,

the retrieval completion reports, and the notes recorded by the Process Engineers in the material

balance calculation spreadsheets. Several hundred Problem Evaluation Requests, also known as

PERS, were reviewed and determined to not provide new pertinent information. The Document

Management Control System database was searched for lessons learned reports. No lessons

learned reports were found for the campaigns being evaluated.

2.1 EVALUATED RETRIEVAL SYSTEMS

There have been three distinct types of retrieval systems used in 241-C Tank Farm retrieval

efforts: the Modified Sluicing Waste Retrieval System (WRS), the Mobile Arm Retrieval System

(MARS) – Sluicing, and MARS – Vacuum. The five campaigns evaluated in this report used

either the WRS or the MARS – Sluicing.

There are three styles of sluicers used in the sluicer-based retrieval systems: the standard sluicer,

the Extended Reach Sluicer System (ERSS) sluicer, and the arm-mounted sluicer used with the

MARS. All of the sluicers are hydraulically driven. The standard sluicer is capable of pan and

tilt movement. The ERSS consists of an extendable boom-mounted sluicer capable of pan and

tilt movement. The boom allows the ERSS sluicer nozzle to be placed closer to the waste

therefore increasing the sluicing effectiveness in breaking up solid waste in the single-shell tank

(SST). The ERSS are also equipped with two high-pressure water nozzles located on either side

of the sluicing nozzle.

2.1.1 Modified Sluicing Waste Retrieval System

A WRS includes three main components in the SST being retrieved and two in the receiving

double-shell tank (DST). The three SST components are two sluicers and a slurry pump. The

DST components are a slurry distributor, and a supernatant pump. The sluicers are generally

placed in risers toward the outside of the SST and the slurry pump located in the center. In the

DST, the slurry distributor and supernatant pump are co-located in the central pump pit. The

slurry distributor is a passive device which is manually raised or lowered. The supernatant pump

may be either electrically or hydraulically driven while the slurry pump is hydraulically driven.

During retrieval, the slurry pump is lowered as the SST waste level lowers. The supernatant

2

pump is raised as the solids level in the DST increases. The slurry distributor is raised and

lowered as necessary to minimize the amount of solids in suspension and therefore returned to

the SST in the supernate.

Hose-in-hose-transfer lines (HIHTLs) connect the two tanks via a portable valve pit and a

portable diversion box. Other ancillary equipment required for a WRS-based retrieval include

active ventilation systems on both the SST and DST tanks, leak detection, and in-tank cameras

and associated lighting systems.

2.1.2 Mobile Arm Retrieval System – Sluicing

A MARS includes two main components in the SST being retrieved and two in the receiving

DST. The two SST components are an arm-mounted sluicer and a slurry pump. The DST

components are a slurry distributor and a supernatant pump. The sluicer arm and slurry pump

are generally placed in risers located in the center of the SST. In the DST, the slurry distributor

and supernatant pump are co-located in the central pump pit. The slurry distributor is a passive

device which is manually raised or lowered. The supernatant pump may be either electrically or

hydraulically driven while the slurry pump is hydraulically driven. During retrieval, the slurry

pump is lowered as the SST waste level lowers. The supernatant pump is raised as the solids

level in the DST increases. The slurry distributor is raised and lowered as necessary to minimize

the amount of solids in suspension and therefore returned to the SST in the supernate.

HIHTLs connect the two tanks via a portable valve pit and a portable diversion box. Other

ancillary equipment required for a WRS-based retrieval include active ventilation systems on

both the SST and DST tanks, leak detection, and in-tank cameras and associated lighting

systems.

2.2 EVALUATED CAMPAIGNS

The retrieval campaigns evaluated are discussed in the following sections. The campaigns were

selected based on their use of MARS, standard, and ERSS sluicer technology, and their use of

diverse media to mobilize the waste.

2.2.1 241-C-101 Bulk Retrieval

Tank 241-C-101 was retrieved using a WRS with ERSS sluicers. Retrieval occurred from

December 2012 until September 2013 with the following non-equipment failure-related

interruptions:

Resources were diverted from the 241-C-101 retrieval to support the 241-C-107 retrieval

on March 19, 2013, and were not available until May 14, 2013;

Resources were diverted to support the 241-C-107 retrieval efforts again from May 18,

2013, until June 2, 2013;

RPP-RPT-58298 3/9/2015 - 7:47 AM 12 of 106

Delays for installation and testing of high-pressure water support equipment occurred

from June 20, 2013, to July 8, 2013, and from September 3, 2013, to September 5, 2013;

and

An event investigation interrupted retrieval from August 22, 2013, until September 3,

2013.

The sluicing media used for the more readily retrieval solids was supernate from 241-AN-101.

High pressure water was the media used for larger pieces of hard waste that could not be broken

up by typical sluicing methods.

2.3 EVALUATED EQUIPMENT

Equipment included in the evaluation can be separated into two categories: SST-specific

equipment and shared equipment. The shared equipment includes the SST ventilation systems,

all of the DST equipment, the majority of the HIHTLs, the valve pits, the diversion boxes, and

control trailers.

The 241-C Tank Farm SSTs were retrieved to either 241-AN-101 or to 241-AN-106. The shared

equipment associated with the 241-AN-101 receiver tank is:

The POR137-WT-TRLR-001 control trailer,

The POR138-WT-VP-001 valve pit,

The POR134-WT-DB-001 diversion pit,

The 241-AN-101 transfer pump, and

The HIHTL which connects them.

Four of the campaigns evaluated were retrieved to 241-AN-101. These are the 241-C-101,

241-C-111, and both of the 241-C-112 retrievals. In addition to these tanks, 241-C-102 and

241-C-104 used 241-AN-101 as their receiver tank.

The shared equipment associated with the 241-AN-106 receiver tank is:

The POR104-WT-VP-001 valve pit,

The POR209-WT-DB-001 diversion pit,

The 241-AN-106 transfer pump, and

The HIHTL which connects them.

The 241-C-107 retrieval utilized 241-AN-106 as its receiver tank. MARS activities have a

dedicated control trailer, POR246-WT-TRLR-001. Other tanks which used 241-AN-106 as their

receiver tank include 241-C-103, 241-C-106, 241-C-108, 241-C-109, and 241-C-110. These

tanks used WRS for retrieval and used a WRS-dedicated control trailer.

All seven of the 241-AN Tank Farm tanks use the same primary tank ventilation system, the AN

ventilation tank primary (VTP). DSTs are required to maintain active ventilation and are

connected to the ventilation systems continuously. The 16 SSTs in the 241-C Tank Farm only

require active ventilation during retrieval activities and are usually passively ventilated. There

are two main ventilation systems in 241-C Tank Farm, POR008 and POR107. POR107 has been

connected to POR03 in order to increase the exhaust flow rate provided by the system. Many of

the SSTs in 241-C may be connected to either the POR008 ventilation system or to the

POR107/POR03 ventilation system.

Each of the SSTs includes sluicers, either standard, ERSS, or arm-mounted, and adjustable

height slurry pumps. In the WRS configuration, each of the sluicers is equipped with a hydraulic

power unit (HPU). Sluicer functions are controlled via a hydraulic valve manifold. The MARS

arm-mounted sluicer is also hydraulically driven and controlled with hydraulic valves. The

slurry pumps also are equipped with an HPU.

The DSTs each have an adjustable height slurry distributor as well as an adjustable height

supernatant pump. The pumps used in 241-AN-101 are hydraulically driven and as such are

equipped with an HPU. Tank 241-AN-106 used both electrically driven and hydraulically driven

pumps during the retrieval campaigns evaluated.

Sluicing activities are conducted using in-tank cameras, two per SST, which allows the operator

to determine the retrieval progress and direct the sluicer nozzle. These are portable camera units

with a built in light. In addition to the camera light, additional in-tank lighting is provided for

each camera.

Water at 241-C Tank Farm is provided from a common source, POR135.

These components and the instrumentation monitoring them were included in this evaluation.

3.0 METHODOLOGY

The information contained in Appendices A through E document a total of 487 events occurring

over 390 operating days. These events were sorted into a number of categories which were

suggested by the development of Appendices A through E. These categories are:

Hydraulic leak events,

Ventilation events,

Camera and lighting events,

Supernatant pump start-up and shut-down events,

Supernatant pump flow rate events,

Slurry pump flow rate events,

RPP-RPT-58298 3/9/2015 - 7:47 AM 17 of 106

Slurry pump movement events,

Sluicer / ERSS / arm movement events,

Hydraulic temperature events, and

Other miscellaneous events.

Tables documenting the events by day and category for each retrieval campaign are contained in

Appendices F through J. Events were tallied in each category for each day. If a particular event

happened multiple times on a given day, it was counted as a single instance since it was likely

reoccurring due to not having completely resolved the initiating event. If a new initiating event

occurred on the same day, it counted as a new event in the tally. For example, if the ventilation

system was shut-down due to a continuous air monitor (CAM), it counted as a single event, even

if the ventilation system was shut down multiple times for CAM problems on that day. If there

were also seal pot issues on the same day, it would count as a separate event on that day.

Event categorizations by category over time for the entirety of the campaigns reviewed are

included in Appendix K.

4.0 FINDINGS

4.1 SIGNIFICANT DELAY EQUIPMENT FAILURES

There were four equipment failures which required component replacements resulting in

significant interruptions in the retrieval process. These failures were:

The AN106-WT-P-22 electric pump which failed during retrieval activities;

The AN106-WT-P-23 electric pump which failed during pre-installation testing;

The AN106-WT-P-24 hydraulic pump which failed during retrieval activities; and

The 241-C-107 slurry pump which failed during retrieval activities.

Retrieval activities did not resume for 208 days after the failure of the AN106-WT-P-22 pump

and subsequent failure of the AN106-WT-P-23 pump during testing. After the AN106-WT-P-24

pump failure, retrievals did not resume for an additional 241 days. Retrievals resumed 198 days

after the failure of the 241-C-107 pump. All of the pump failures were associated with the

241-C-107 MARS retrieval efforts. Given that the other retrieval efforts associated with the

241-AN-106 receiving tank are not within the scope of this review, it is not possible to evaluate

the total number of hours of pump use prior to failure.

No other failures were noted which resulted in a sustained suspension of retrieval activities.

4.2 MINOR DELAY EQUIPMENT FAILURES

The vast majority of failures resulted in short duration shutdowns or reduced capacity during

continued operations. The typical short duration shutdown impact was less than one shift with a

few extending into one or two days while the equipment was undergoing troubleshooting. The

other failures included here typically resulted in reduced capacity such as lost mobility in a

sluicer nozzle or reduced flow from a sluicer nozzle. The events are summarized by tank in the

following subsections. Trends and analysis of the findings are discussed in Section 4.3.


The information documented in Appendix A was sorted into the categories listed in Section 3.0,

“Methodology.” The resulting table is in Appendix F. A total of 110 entries were made

documenting issues over 101 days of operation. Figure 4-1 shows the distribution of the events

between categories. No trends were noted within the 241-C-101 information. Analyses of each

of the categories are summarized in the following subsections.

Figure 4-1. 241-C-101 Bulk Retrieval Recorded Events.

4.2.1.1. Hydraulic Leak Events. Eight hydraulic leak events were recorded during the

241-C-101 bulk retrieval campaign. Two of these events were associated with the slurry pump

HPU. One event was associated with the supernatant pump HPU. The other five were

associated with the two sluicers.

The slurry pump HPU leaks were at a flange on the HPU. The supernatant pump hydraulic leak

was at the pressure hose connection point of the HPU. All three of these leaks appear to have

been repaired with minimal impact to the retrieval efforts.

One of the sluicer leak entries was associated with the number 1 sluicer. The leak was apparent

during operation of the horizontal movement function. The hose providing the function was

disconnected. Operation of the number 1 sluicer continued utilizing vertical movement of the

nozzle.

The remaining four hydraulic leak events noted were associated with the number 2 sluicer.

Those four entries documented the discovery and effects of the same two failures. The leaks

associated with the number 2 sluicer were at the rotary union. The initial entry identified both

leaks. The horizontal motion function had a drip-wise leak at the rotary union. A steady stream

of hydraulic fluid was observed at the rotary union during vertical motion. Sluicing continued

with the number 2 sluicer using the horizontal motion functions while the hoses to the vertical

motion functions were disconnected. Later investigation attributed these leaks to electro-spark

damage to the Teflon hydraulic hoses as identified in RPP-RPT-55036, “Summary Evaluation of

ERSS Hydraulic Hose Failures”. Corrective actions are in place to address this issue.

4.2.1.2. Ventilation Events. Seventeen entries were logged associated with ventilation issues.

Ten of the events were associated with the POR107 ventilation system, one was related to the

241-C-101 demister, and the remaining six were associated with the 241-AN VTP.

Eight of the 17 entries were associated with the CAMs, 5 on the POR107 ventilation system and

3 on the 241-AN system. Three entries documented the efforts associated with a single event of

the POR107 glycol heater smoking. The five entries note issues with the POR107 seal pot

temperature, the POR107 low flow alarm, the POR107 sample pump, high differential pressure

across the 241-C-101 demister, and entering an extended outage for 241-AN VTP upgrades for

compliance with RPP-13033, “Tank Farms Documented Safety Analysis.” One entry simply

noted that the 241-AN ventilation system was shut down.

4.2.1.3. Camera and Lighting Events. Fourteen entries were logged associated with the in-

tank cameras and lighting systems. Only one of the camera and lighting entries was for the

241-AN-101 camera. The remaining 13 entries were for the 241-C-101 in-tank cameras and

lights.

There were five entries associated with the in-tank lighting, including a stop work on the use of

all Alhberg lighting and three for the cameras and lighting. The camera and lighting installed in

Riser 3 had the majority of entries with replacement being noted ten times. The cameras and

lighting installed Riser 8 required replacement seven times.

4.2.1.4. Supernatant Pump Start-Up and Shut-Down Events. The 241-C-101 retrieval data

did not contain any information indicating the 241-AN-101 supernatant pump was having start-

up or shut-down issues.

4.2.1.5. Supernatant Pump Flow Events. Four entries noted problems with the 241-AN-101

supernatant pump flow rate. Three of these events were likely related to inlet screen plugging.

The fourth documents a loss of pump HPU speed increase/decrease controls. The HPU speed

control issue self-corrected as the system worked as designed during troubleshooting.

4.2.1.6. Slurry Pump Low Flow and Plugging Events. Twenty low flow and plugging events

were noted during the 241-C-101 campaign. Two of these events were associated with final

pump down as part of the volume displacement activities. The other 18 appear to have been

expected events as there was no indication that engineering or maintenance was notified.

4.2.1.7. Slurry Pump Movement Events. Three entries documented difficulties in moving the

slurry pump. All three events appear to have been due to material below the pump creating a rest

for the pump. The logs do not indicate that engineering or maintenance was notified, suggesting

this was expected behavior from the pump.

4.2.1.8. Sluicer / Extended Reach Sluicer System / Arm Movement Events. A single event

was noted during the 241-C-101 campaign. The sluicer number 1 controls were operating

backward, e.g., the command to move the nozzle in the upward direction resulted in downward

motion, etc. Engineering confirmed that the sluicer was oriented 180 degrees out causing the

backward nozzle controls. This was neither the first nor the last use of sluicer number 1.

4.2.1.9. Hydraulic Temperature Events. Twenty-one entries noted hydraulic system

temperature anomalies. Five instances were for low temperature, the other 16 were for high

temperature.

4.2.1.10. Miscellaneous Events. Twenty-two events were noted which did not appear to either

fit within one of the other categories or to reoccur. Figure 4-2 shows the distribution of the

events over time. The trend does not show that there was a noticeable difference in the rate of

occurrence associated with campaign start-up.

4.2.1.11. Total Number of Events. Figure 4-3 is a graph showing the distribution of the 110

events over time. As with the rate of miscellaneous events, the trend does not show that there

was a noticeable difference in the rate of occurrence associated with campaign start-up. The

events occur at a steady rate over the duration of the campaign. This suggests that the

construction and start-up testing processes are of sufficient quality as to not adversely impact

operations.

4.2.2 241-C-107 Retrieval

The information documented in Appendix B was sorted into the categories listed in Section 3.0,

“Methodology.” The resulting table is in Appendix G. A total of 231 entries were made



the categories are provided in the following subsections.

Figure 4-4. 241-C-107 Retrieval Recorded Events.

4.2.2.1. Hydraulic Leak Events. Nine hydraulic leak events were noted during the 241-C-107

campaign. Two events documented a drop in the supernatant pump hydraulic fluid level with no

apparent leakage immediately prior to failure of the pump. Two events were associated with a

spray leak by a filter in the POR237-WT-ENCL-400 hydraulic cabinet. A fitting leak at

POR241-WT-HPU-001 was noted as was a leak at the constant tension hoist reel in the MARS

containment box. Two events documented a seal leakage from the wrist sweep stack valve. The

final hydraulic leak event noted a steady stream of fluid from POR237-WT-ENCL-400.

4.2.2.2. Ventilation Events. Ventilation issues were noted 37 times during the campaign.

Thirty-two of the entries were associated with POR107, three were associated with POR03, and

one each with POR008 and the AN VTP.

Twenty of the events noted were associated with either the CAM or the record sampler. One of

these events was the result of a confirmed high radiation condition on the sample paper.

Thirteen events were associated with the instrument flow rates. The other six events were noted

as CAM failures.

The other 17 events documented a variety of issues including 2 for Human-Machine Interface

(HMI) issues and 3 for control valve problems. Four events noted involved the 241-C-107

pressure transmitter. Five events were associated with problems with the stack temperature

differential. There was a single instance noted of low stack flow and two instances of the

systems shutting down without a cause being identified.

4.2.2.3. Camera and Lighting Events. Two camera and lighting events were noted. The first

event noted that the Riser 2 and Riser 7 cameras in 241-C-107 had both degraded to near failure

and that retrieval was not able to continue with the resulting visibility. The second event noted

that the 241-AN-106 camera had failed.

4.2.2.4. Supernatant Pump Start-Up and Shut-Down Events. Supernatant pump start-up or

shut-down events were noted on five occasions. Two of the events were associated with signal

problems for the flow control valves. The other three instances were simply described as “timed

out.”

4.2.2.5. Supernatant Pump Flow Events. There were 13 events noted associated with low

flow from the supernatant pump. Two were associated with the failure of the AN106-WT-P-22

electric pump. Two occurred when the pump speed was being ramped up or down. One event

was associated with flow control valve issues while another was documented as being due to the

MARS’ arm being moved to 90 degrees. Seven other events were associated with blockage of

the intake screen.

4.2.2.6. Slurry Pump Low Flow and Plugging Events. Plugging of the slurry pump intake

screen and associated shut down was noted on 71 days. Many of these days had in excess of five

events of shut down per shift worked. The logs do not indicate that engineering or maintenance

was notified, suggesting this was expected behavior from the pump. RPP-RPT-54959 notes that

the supernate used as sluicing medium starting in early 2014 reacted with the solids, creating

phosphate crystallized waste solids agglomerations within 241-C-107. Subtracting the events

after the introduction of the phosphate bearing supernate leaves 45 days where there were low-

flow related shut downs not related to the phosphate crystallized waste solids agglomerate. A

quick count indicates that in excess of 250 shut downs were experienced during these 45 days.

As this is the only example of the MARS retrieval technology included within the scope of this

analysis, it is not possible to determine if the reason the waste was not being broken down into

pieces small enough to be transferred was due to the waste type or due to the retrieval

technology.

There were four additional events documenting issues with the slurry pump speed sensors. The

first entry simply states that there were issues with the speed sensors. The second and third

entries documented the troubleshooting evolution associated with the failure of both speed

sensors. The final entry states that the speed sensor shows 0 rpm on start-up. No additional

information was provided.

4.2.2.7. Slurry Pump Movement Events. The slurry pump and back stop could not be moved

as desired 11 times during the campaign. Nine of the events were associated with the pump; the

other two were for issues with the back stop.

Pump movement was limited due to the lower cable limit six times. There was a single instance

of the pump not lowering because the contactor had tripped and one from having blockage

beneath it. The final entry discusses the slurry pump dragging when the turntable was rotated

which affected the reeving of the cable onto the winch. There were no apparent long-term ill-

effects to the winch.

There was one instance of the backstop being limited by the lower cable limit and one instance

of the backstop not moving without a cause being given.

4.2.2.8. Sluicer / Extended Reach Sluicer System / Arm Movement Events. There were 15

entries associated with the movement of the MARS’ arm. Seven of the events were related to

HMI operation. Problems with the constant tension hoist resulted in five entries. Two entries

were associated with failure of the proximity switches and the associated compensating efforts.

There was one documented instance of problems with the HPU and one where the curb feeler

stopped actuating.

4.2.2.9. Hydraulic Temperature Events. The hydraulic fluid temperature was either too high

or too low eight times.

RPP-RPT-58298 3/9/2015 - 7:47 AM 26 of 106

4.2.2.10. Miscellaneous Events. Fifty-five events were noted which did not appear to either fit

within one of the other categories or to reoccur. Figure 4-5 is a graph showing the distribution of

the events over time. The trend does not show that there was a noticeable difference in the rate

of occurrence associated with campaign start-up.

Figure 4-5. 241-C-107 Retrieval Miscellaneous Events.

Five leak events were associated with the rotary union. During an interview with 241-C-107

project personnel, it was discovered that the leaks observed were not hydraulic leaks as

originally believed from the entries, but were waste leaks (WRPS-PER-2012-1321, “Evidence of

Previous leakage from the Rotary Union on the C-107 MARS Unit” and WRPS-PER-2012-1346,

“C-107 MARS Containment Box Rotary Union Drip Leak”). The project determined that the

leaks were the result of the manufacturing methods used when fabricating the rotary union. A

new rotary union was fabricated using a modified manufacturing method and installed in the

241-C-107 MARS. No leaks were observed at the rotary union after the new union was

installed.

The information documented in Appendix C was sorted into the categories listed in Section 3.0,

“Methodology.” The resulting table is in Appendix H. A total of 37 entries were made



the categories are provided in the following subsections.


4.2.3.1. Hydraulic Leak Events. The 241-C-111 campaign log books did not document any

hydraulic leak events.

4.2.3.2. Ventilation Events. There were nine events noted associated with the ventilation

system in the log books. All nine events were associated with the 241-C Farm ventilation

systems, split between POR008 and POR03.

POR008 had two events. The first event noted was the system making significant noise and

cycling the variable frequency drive. Toward the end of the campaign, the system was shut

down on rate of increase in differential pressure.

POR03 was involved with seven events. Five of the events were associated with the CAM, one

documented software modifications, and one addressed a low plenum flow condition.

4.2.3.3. Camera and Lighting Events. Camera and lighting events were noted seven times

during the campaign. The first entry may reflect the initial camera and lighting installation. A

second entry later in the campaign documents replacing the Riser 7 camera and lighting. The

Coffman lights were noted to have high amps on three occasions, once in Riser 1, once in Riser 7

and one entry did not indicate which riser was affected. The Riser 7 high amp entry was

followed shortly by the light in Riser 7 failing.

Three entries discussed concerns with the camera. The camera was noted to have lost the ability

to rotate. Shortly afterward an entry stated that the camera was adjusted. The entries did not

indicate which camera was involved. The Riser 1 camera was noted to have electrical issues

early in the campaign with burned wiring and a failed ground-fault circuit interrupter breaker.

4.2.3.4. Supernatant Pump Start-Up and Shut-Down Events. A single event was noted

indicating the supernatant pump had difficulties with start up or shut down. The pump would not

come up to speed in a timely fashion and would time out. Four attempts to start the pump all had

the same result – they timed out before the pump could reach operating speeds. Engineering

provided direction to wait 5-10 minutes after starting the HPU before attempting to increase the

supernatant pump speed. The log book indicates that this approach was successful.

4.2.3.5. Supernatant Pump Flow Events. The supernatant pump was observed to have 11

flow events. All of these events appear to be related to the speed indication and how it affected

the flow rate. Ten of these events took place over 14 operating days. During these 14 days,

operations continued with intermittent pauses for trouble shooting.

4.2.3.6. Slurry Pump Low Flow and Plugging Events. The slurry pump was noted to have

two low flow events. The first was associated with material build up and appears to have been

an expected event as there was no indication that engineering or maintenance was notified. The

second coincided with a supernatant pump shut down, also on low flow. The shift log noted that

the reason for the second shut down was unknown.

4.2.3.7. Slurry Pump Movement Events. One entry noted that the slurry pump went slack

when attempting to lower the pump. The logs do not indicate that engineering or maintenance

was notified, suggesting this was expected behavior from the pump.

4.2.3.8. Sluicer / Extended Reach Sluicer System / Arm Movement Events. The 241-C-111

campaign log books did not document any sluicer movement events.

4.2.3.9. Hydraulic Temperature Events. The 241-C-111 campaign log books did not

document any hydraulic temperature excursions.

The information documented in Appendix D was sorted into the categories listed in Section 3.0,

“Methodology.” The resulting table is in Appendix I. A total of 69 entries were made


between categories. No trends were noted within the 241-C-112 bulk retrieval information.

Analyses of each the categories are provided in the following subsections.


4.2.4.1. Hydraulic Leak Events. There were six notations of hydraulic leak events. Five of

these notations address the actions surrounding a leak associated with sluicer number 1. The

other notation documents a slurry pump HPU drip.

4.2.4.2. Ventilation Events. Nine ventilation events were documented during the 241-C-112

bulk retrieval campaign. One of these events documented that both POR008 and the 241-AN

VTP systems were off-line due to a power outage. There were four instances where the POR008

seal pot transmitter was indicating either a high or low level. It was noted that the low level

events appeared to be related to low ambient temperatures affecting the sensing legs. There were

two instances where the documentation simply stated that the 241-AN VTP was off-line. There

were also two notations documenting POR008 high differential pressure events.

4.2.4.3. Camera and Lighting Events. There were 15 entries associated with the cameras and

lighting. Four of the notations documented camera issues without indicating there were

problems with the lights. Four indicated instances where both the cameras and the lighting were

inoperable or significantly degraded. Of these four, three of them were associated with a single

event where both of the cameras and all of the lights were impacted. The delay associated with

this event was longer than typical for camera or lighting issues due to poor weather curtailing

field activities.

There were seven entries which only addressed lighting issues. By the end of the campaign, as

soon as a light was replaced, the one in the other riser would fail, to the point that operations was

noting that only one light at a time would be used in an attempt to conserve the lights.

4.2.4.4. Supernatant Pump Start-Up and Shut-Down Events. The supernatant pump had

start-up or shut-down events noted seven times. Six of these events address start-up concerns,

while the remaining one is for a delay in the pump shutting down. All seven of the events appear

to be based on controlling the pump from the control trailer instead of at the HPU. All six

instances related to pump start-up include discussion on the pump amps not increasing. The log

books indicate that the pump would either start later that day or the next day without

maintenance or repair.

4.2.4.5. Supernatant Pump Flow Events. Events related to supernatant pump flow were noted

six times. All six events appear to be related to intake screen blockage. Operations documented

several attempts to clear the blockage with drain back with varying success. Flushing of the line

was used in two instances which cleared the blockage and the flow rates returned to the expected

ranges.

4.2.4.6. Slurry Pump Low Flow and Plugging Events. The slurry pump was noted to have

low flow and plugging events on seven days. This appears to have been anticipated behavior as

there was no indication that engineering or maintenance was notified.

4.2.4.7. Slurry Pump Movement Events. The slurry pump was noted to have hampered

movement on four occasions. In all four instances, it is likely that the pump was resting on

solids which prevented the pump from going lower into the tank. This appears to have been

anticipated behavior as there was no indication that engineering or maintenance was notified.

4.2.4.8. Sluicer / Extended Reach Sluicer System / Arm Movement Events. A single entry

for sluicer number 2 indicates that the sluicer’s range of motion was limited to around 180

degrees.

4.2.4.9. Hydraulic Temperature Events. Two events were noted where the hydraulic fluid

temperature disrupted operations. Both entries document low temperature conditions.

associated with campaign start-up.

4.2.5 241-C-112 Hard Heel Retrieval

The information documented in Appendix F was sorted into the categories listed in Section 3.0,

“Methodology.” The resulting table is in Appendix J. A total of 42 entries were made


between categories. No trends were noted within the 241-C-112 HHR information. Analyses of

each the categories are provided in the following subsections.

Figure 4-13. 241-C-112 Hard Heel Retrieval Recorded Events.

4.2.5.1. Hydraulic Leak Events. The 241-C-112 HHR campaign log books did not document

any hydraulic leak events.

4.2.5.2. Ventilation Events. Fourteen ventilation events were noted during the 241-C-112

HHR campaign. Three events were related to the POR008 seal pot level transmitter sending

erroneous high or low level signals. Two events documented the 241-AN VTP being shut down.

The remaining nine events document POR008 high differential pressure across various

components. All nine of these events appear to have been correctly indicated. Although

engineering was contacted for direction to proceed under the high differential pressure

conditions, maintenance was not called for equipment repair.

4.2.5.3. Camera and Lighting Events. The cameras and lighting were noted to have impacted

the retrieval four times during the 241-C-112 HHR campaign. The four entries document that

the Riser 6 camera was replaced twice, the riser 3 camera was replaced once, the riser 6 lights

were replaced once, and the riser 3 lights were replaced twice.

4.2.5.4. Supernatant Pump Start-Up and Shut-Down Events. The 241-C-112 HHR

campaign log books did not document any supernatant pump start-up or shut-down events.

4.2.5.5. Supernatant Pump Flow Events. The 241-C-112 HHR campaign log books did not

document any supernatant pump flow events.

4.2.5.6. Slurry Pump Flow Events. There were two instances noted of slurry pump flow

excursions. The first instance resulted from a speed sensor failure. The second entry noted a

low flow event resulting from blocking of the intake screen.

4.2.5.7. Slurry Pump Movement Events. A single event was identified where the slurry pump

was raised and then lowered. The end position of the pump appeared the same as the original

position despite being raised and lowered different amounts. The log noted that there were

several turns of slack on the pump. As neither engineering nor maintenance were notified, it is

likely that the pump was resting on solids.

4.2.5.8. Sluicer / Extended Reach Sluicer System / Arm Movement Events. One entry

documented that sluicer number 2 was unable to rotate toward the sample sleeve opening. Thirty

minutes later, sluicer number 2 was fully rotating again.

4.2.5.9. Hydraulic Temperature Events. Four hydraulic fluid temperature excursions were

noted. Three of the events were associated with the slurry pump HPU while the other was

associated with the supernatant pump HPU. These events were in addition to those instances

where the ambient temperature drove the overall pit temperatures below the range where

transfers could occur.

4.3 EQUIPMENT FAILURE TRENDS

There were 487 events noted in the retrieval information reviewed in this analysis. The table

tallying the events is contained in Appendix K. Figure 4-16 shows the distribution of the events

between categories. Trends were not observed on an individual retrieval basis as documented

above. Of interest in this finding is that there was not an increase in events at the start or the end

of the retrieval activities indicating that the failures are not entirely related to installation

concerns or equipment wear. Comparison of the total number of events per retrieval campaign

did not reveal any significant trends. An evaluation of the events based on the categories

described in Section 3.0, “Methodology,” is detailed in the following subsections.

Figure 4-16. Retrieval Campaign Recorded Events.

4.3.1 Hydraulic Leak Events

Hydraulic leaks were noted a total of 23 times. Nine of these events were noted during the

241-C-107 retrieval activities. No leaks were noted during the 241-C-111 bulk retrieval

activities or the 241-C-112 HHR activities.

Four of the events were related to the slurry pumps, with an additional three associated with

supernatant pumps. Twenty-one were specified as having come from the sluicer associated

equipment. Eleven of the sluicer related failures were on the MARS arm. The majority of the

hydraulic leaks resulted in the equipment continuing in service with reduced retrieval efficiency.

Notable exceptions to this trend were the two hydraulic leak entries immediately prior to the

failure of supernatant pump AN106-WT-P-24. Seven of the leaks were in components external

to the tank while the other 21 occurred inside the tank or tank headspace.

One particular category of equipment was noted as leaking on multiple occasions. Two of the

hydraulic leaks from the 241-C-101 bulk retrieval were from a rotary union. Further

investigation into the 241-C-101 hydraulic leaks attributed these to electro-spark damage to the

Teflon hydraulic hoses. Waste leaks from the rotary union are discussed in Section 4.3.10.

4.3.2 Ventilation Events

Eighty-six entries in the various logs were connected to the four ventilation systems – POR107,

POR03, and POR008 in 241-C Farm and the 241-AN VTP. The 241-AN VTP being shut down

affected the retrieval campaigns 12 times. POR03 was shut down in a manner that delayed

retrieval 10 times while POR008 was noted as being shut down unexpectedly 22 times. POR107

impacted retrieval 42 times.

The ventilation failure mode which occurred most frequently involved the CAM or record

samplers. The stack particulate emissions monitoring systems disrupted retrieval 32 times

during the various campaigns. Many of these alarms were due to low record sample or CAM

sample flow. It is recommended that the record sample and CAM systems and the rate of

associated alarms be further investigated to explore design improvements (e.g., a different

vacuum pump) and alternate operational strategies (e.g., increasing the rate of filter paper change

out).

The next most common alarm condition was high differential pressure across various ventilation

components including the pre-filter, heater, and filters. The majority of the high differential

pressure events were associated with the hot water use during the 241-C-112 HHR activities.

Although they did not result in alarms, visibility issues (i.e., foggy conditions within the tank)

were noted many times during the high-pressure wall washing at the end of the various retrieval

activities. Reducing the rate at which the hot water is sprayed may help reduce the number of

differential pressure alarms. Increasing the tank’s ventilation flow rate would help with the

foggy conditions; however, it may increase the rate that the filter is loaded with water, which is

causing the high differential pressure alarms.

4.3.3 Camera and Lighting Events

Camera and lighting events are fairly common and occurred during all of the evaluated retrieval

campaigns. A total 42 entries were noted where at least one of these components required

replacement. Frequently, the cameras and lights were replaced at the same time. In total, the

cameras were replaced 32 times, as were the lights. Although these camera and lighting systems

serve their function well, there may be a more cost-effective solution than continuing to replace

the failed components with the same ones currently implemented in the field.

RPP-RPT-58298 3/9/2015 - 7:47 AM 42 of 106


33

4.3.4 Supernatant Pump Start-Up and Shut-Down Events

Unexpected conditions during the start up or shut down of the supernatant pump were noted 13

times during the 5 retrieval campaigns. Ten times the pumps did not start or stop and were

described as having timed out. Generally the timing out was indicative of either a problem with

the signal from the control trailer to the HPU or the hydraulic fluid being too cold.

The other common failure was related to the operation of the supernatant line flow control

valves. The 241-C-107 retrieval activities had several events where the flow control valves did

not respond as anticipated which resulted in the pump shutting down for low flow conditions.

The logs indicate that the flow control valve problems were signal related and not associated

with valve or actuator failure.

4.3.5 Supernatant Pump Flow Events

There were 34 entries associated with supernatant pump flow events. Sixteen of the events were

associated with the intake screen being blocked, apparently an anticipated behavior as there was

no indication that engineering or maintenance was notified. Two of the events were documented

just prior to the failure of the AN106-WT-P-22 electric pump. Two other events were related to

operation of the flow control valves or the sluicer.

Fourteen events were related to issues with the speed sensors and the pumps’ response to

increases and decreases in speed. Evaluation of the pump speed and flow rate control devices

and the correct device to use for monitoring for each parameter during retrieval campaigns may

reduce the number of operational upsets.

4.3.6 Slurry Pump Low Flow and Plugging Events

Slurry pump low flow events were noted on 102 days. One event was attributed to the pump

timing out. There were two events clearly related to the final pump down process and four

events caused by issues with the speed sensors.

The slurry pump was shut down due to low flow on 99 days. The majority of these are during

the 241-C-107 retrieval campaign. On the 28 days where low flow shut down the pumps during

the other campaigns, one or two events were typically noted per day. During the 241-C-107

campaign, most of the days documented more than five low flow slurry pump events per shift

worked. As noted above, over one three-day period, the 241-C-107 slurry pump was shut down

due to low flow 34 times. The total number of 241-C-107 events was not tallied for this

analysis; however, it is likely that the pump was shut down on low flow more than 200 times.

The logs do not indicate that engineering or maintenance was notified, leading one to believe that

this was anticipated behavior. As the 241-C-107 campaign is the only example of the MARS

retrieval technology included within the scope of this analysis, it is not possible to determine if

the reason the waste was not being broken down into pieces small enough to be transferred was

due to the waste type or due to the retrieval technology. An evaluation of retrieval campaigns

which would include multiple retrieval efforts using the MARS technology is recommended to

RPP-RPT-58298 3/9/2015 - 7:47 AM 43 of 106


34

determine if the MARS equipment should include additional equipment to reduce waste chunk

sizes.

4.3.7 Slurry Pump Movement Events

The slurry pump did not adjust its position as desired on 20 occasions. Ten of these events were

associated with a build-up material under the pump, restricting its downward progress. Seven

events were recorded when the 241-C-107 slurry pump reached the lower cable limit and was

unable to be further lowered. There was one instance where the pump did not move which was

attributed to the contactor having been tripped. The final event documented an occasion where

the 241-C-107 pump dragged on the bottom of the tank when the turntable was rotated.

4.3.8 Sluicer / Extended Reach Sluicer System / Arm Movement Events

Eighteen events were noted where the sluicer apparatus did not respond as anticipated. Fifteen

of these were during the 241-C-107 campaign. As the 241-C-107 campaign is the only example

of the MARS retrieval technology included within the scope of this analysis, is it not possible to

determine if the relatively high percentage of events associated with the 241-C-107 retrieval is

due to the MARS approach or is specific to the equipment installed in the 241-C-107 retrieval

equipment.

Eight of the events were attributed to problems with the control system, with seven of them from

the 241-C-107 campaign. The 241-C-107 campaign also noted five events where the constant

tension hoist, used to maintain the cables and lines leading to the end effector and its associated

nozzles and sluicer cannon, did not respond correctly and impacted the retrieval efforts.

4.3.9 Hydraulic Temperature Events

Thirty-five entries noted that the HPU temperature was either too high or too low. This does not

include entries when the in-pit air temperature readings were below the acceptable limit for

transfers under the waste transfer structure temperature monitoring program. Although the HPU

fluid temperatures were not at shut-down criteria levels, they were close enough that either the

system was not responding as desired or increased monitoring was required to ensure the system

was operating within the acceptable range. Figure 4-17 documents the number of hydraulic

temperature event per operating day by season. The findings suggest that the HPU cooling and

heating systems are not adequate for the temperature extremes of the depths of winter or the

height of summer.

4.3.10 Miscellaneous Events

Many events did not fall into the categories listed in Section 3.0, “Methodology,” and did not

reoccur frequently enough to result in generation of a new category. There were 109 of these

entries noted during the 390 operating days. These were graphed over the number of operating

days in Figure 4-18. The graph shows a steady trend that does not change noticeably over time.

This indicates that the events are not related to campaign start-up or campaign completion.

Figure 4-18. Retrieval Activities Total Miscellaneous Events.

Five 241-C-107 system leaks were from the MARS rotary union. The 241-C-107 project

determined that these waste leaks were the result of the manufacturing methods used when

fabricating the rotary union. Corrective actions are in place for both the hydraulic hose electro-

spark issue discussed in Section 4.3.1 and the fabrication issues with the MARS rotary union.

Further monitoring of these components is recommended to ensure that the corrective actions

have addressed the issues.

4.3.11 Total Number of Events

There were 487 events noted over 390 operating days. These were graphed over the number of

operating days in Figure 4-19. The graph shows a steady trend that does not change noticeably

over time. This indicates that on average the events are not related to campaign start-up, or

campaign completion.

Figure 4-19. Retrieval Activities Total Number of Events.

The events were checked to determine if there were seasonal changes. Figure 4-20 shows the

breakdown by category of the events normalized by operating day by season. With the exception

of the hydraulic thermal events discussed in Section 4.3.9 and the ventilation seal pot transmitter

issues discussed in Section 4.2.4.2, no other significant trends were observed. The slight trend

shown by the miscellaneous events and total number of events indicating that they are more

likely to occur during the summer months may be attributed to the number of weather-related

events noted during the summer months. The miscellaneous category is where events such as

rain induced leak detection events and weather-related work/rest regimes are documented. This

skews the data indicating a seasonal trend.

5.0 RECOMMENDATIONS

This document reviewed the various log books and reports associated with five retrieval

campaigns: 241-C-101 bulk retrieval, 241-C-107 retrieval, 241-C-111 bulk retrieval, 241-C-112

bulk retrieval, and 241-C-112 HHR. A total of 487 events over 390 operating days were noted

that impacted retrieval duration and/or equipment effectiveness. These were graphed over the

number of operating days as shown in Figure 4-19. The graph shows a steady trend that does not

change noticeably over time. This indicates that on average the events are not related to

campaign start-up, campaign completion, or seasonal changes (with the exception of the

hydraulic thermal events discussed in Section 4.3.9 and the ventilation seal pot transmitter issues

discussed in Section 4.2.4.2).

Analysis of the events results in the following recommendations.

Monitor the rotary unions in future MARS installations where the manufacturing method

corrective actions have been implemented to determine if the waste leaks have been

resolved.

The record sample and CAM systems and the rate of associated alarms should be

reviewed to determine if a different design (e.g., a different vacuum pump) and/or

alternate operational strategies (e.g., increasing the rate of filter paper change out) would

reduce the number of ventilation system related outages.

The camera and lighting systems should be evaluated to determine if there may be a more

cost-effective solution than continuing to replace the failed components with the same

ones currently implemented in the field.

Signal transmission for both supernatant and slurry pump control should be reviewed.

Pump start-up, shut-down, and flow control issues were attributed to the system either

timing out or responding erratically in multiple instances.

An evaluation of the parameters and equipment used to control the supernatant and slurry

pumps (e.g., pump speed, flow control valves, flow rate indication, etc.) may lead to

changes in the operating strategy which could improve equipment responsiveness and

reduce inadvertent shut downs. The log entries frequently refer to pump speed with flow

indication and flow rate with speed indication.

An evaluation of retrieval campaigns which would include multiple retrieval efforts using

the MARS technology is recommended to determine if the MARS equipment should

include additional equipment to reduce waste chunk sizes. As the 241-C-107 campaign is

the only example of the MARS retrieval technology included within the scope of this

analysis, it is not possible to determine if the reason the waste was not being broken

down into pieces small enough to be transferred was due to the waste type or due to the

retrieval technology.

An evaluation of the HPU cooling and heating systems is recommended. The 35 entries

associated with either high or low HPU temperatures suggest that the HPU cooling and

heating systems are not adequate for the temperature extremes of the depths of winter or

the height of summer.

An evaluation of the total cost per gallon retrieved should be done for each technology.

A consistent level of detail of the log entries in the various log books is recommended

and would make reviews of this type more fruitful. The logs reviewed for this report do

not consistently identify if a system was restarted after shut down or why the shut down

occurred. Very little can be determined, for example, when the entry simply states that

the 241-AN VTP was shut-down. It is not always clear from the entries on that day if the

retrieval activities were impacted, how long the ventilation system was down, or why the

system went down in the first place.
