Requirement or lnihating Statement

Matenal balance procedures will orovlde an i ~ t ~ d l estimate of the high-hat solids transferredfrom tank 241-12-106 to tank 241-AY-102 during the course of the WRSS operation.

The in-tank temperature trends of the remaining waste and the cooling performance of the ventilation system will be monitored and the data will be used to develop an estimate of the heat load in the tank.

The sludge in tank 241-C-106 is to be cooled before sluicing startup to prevent a potential steam release event during early stages of sludge retrieval operations.

The more restrictive limit of Administrative Control (AC) 5.26 requires cooling the tank 241-C-106 sludge to its wintertime temperahre (FDH 1998b). Winteaime temperatures are achieved when the waste is cooled until the teinperature of thermocouple 1 on the riser 8 thermocouple tree reaches 64 OC (148 T) (Bander et al. 1996). Sludge cooling is accomplished by operating the tank 241-C-106 exhauster (296-P-16) to draw air through the inlet filter system. The WRSS chiller skid supplies a chilled propylene glycoVwater solution to the intake air cooling coil (CC-1361) to cool the air stream to approximately 4 “C (40 T).

As seen in Figure 3-5, the startup condition of tank 241-C-106 needs to be established before beginning supernatant temperature equalization operations.

Tlic tcmoeratures in tanks 241-C-106 and 241-AY-102 are to be moniiored for a penod of not less than 30 days before the start of sluicing operaaons

Tank 241-(2-106 temperature measurements will be obtained from thermocouple trees 8 and 14

The tank 241-C-106 and Table 3-9 thermocouple measurements, which make up the pre-sluicing thermal baseline, are compared to the project thermal analyses to ensure that the temperatures of the tanks are consistent wth the predicted temperatures. Because the actual performance ofboth the 296-P-16 exhauster with inlet air cooling and the tank 241-AY-102 ventilation systems will be determined during the pre-sluicing operations, the project thermal models will also be benchmarked as part of this baselining activity. Gas release rates are determined directly by monitoring the hydrogen concentration in the headspaces of both tanks using installed standard hydrogen monitoring systems (SHMS) and by measuring the ventilation rates.

As specified in the Tank Waste Remediation System Basis for Interim Operation (FDH 1998a), a presluicing flammable gas baseline will be established for both tanks 241-C-106 and 241-AY-102.

During this operation, the sluicer is operated in semi-automatic mode to sweep the supernatant liquid surface to induce mixing. Also, the submersible slurry pump is positioned to minimize solids entrainment. Just before sluicing begins, the supernatant level in tank 241-C-106 will be adjusted to 183 cm (72 in.) (FDH 1998a).

Enough dilute noncomplexed supernatant in tank 241-AY-102 will be pumped to establish an initial liquid waste inventow of 1.67 millionL (440,000 gal). .......... into the tank (241-AY-102) without exceeding the maximum liquid level limit of 9.2 m (364 in.).

Tank 241-AW-102 is the planned receiver for this transfer (see procedure TO-230422). To prepare for the transfer, a waste compatibility assessment will be completed and the transfer route established. Tank 241-AY-102 supernatant will be chemically adjusted by adding approximately 88,000 L (23,000 gal) of 50 weight percent sodium hydroxide (caustic) to adjust the hydroxide concentration to 0.57 molar. Adjustments to the amount of caustic will be made if the volume of supernatant in the tank after the first pumping stage differs by more than 26,500 L (7,000 gal) ... ... . .. ._... The caustic addition is to be accomplished by off-loading caustic solution from a tank truck through a transfer hose connected to riser 15-0 on the tank After tlie caustic is added, four of five 17-ft air lift

circulators will be activated and operated for a minimum of three days to ensure the concentrated caustic is uniformly mixed throughout the tank 241-AY-102 supernatant

. . . . . . . . . ... is removal of the supernatant to reduce the chances of a gas release event occumng andor minimizing the consequences of such an event.

The decision to transfer supernatant and the volume to pump will be based on recommendations of the TRG after evaluating all available information. The transfer routing includes the SN-100 and SL-200 lines between tanks 241-C-106 and 241-AY-102 and the SL-503 transfer line in the 241-AY-02A pit. A jumper will be available for connecting the U11 nozzle (SL-100) to the U3 nozzle of the SL-503 transfer line. Tank 241-AF'-106 is the selected receiver tank (see procedure TO-270-035). As a contingency, a waste compatibility assessment that assumes complete retrieval of tank 241-C-106 waste will be established for transferring the supernatant volume.

The magnitude of temperature increases will not become evident for months due to the large thermal time constant for tank 241-AY-102 (Ogden et al. 1998)). Therefore, the transient temperature response to the waste additions coupled with a thermal model for the tank, must be used to predict the peak temperatures in the tank. . . . ... the first campaign also is characterized by the requirement to maintain a minimum hydraulic head on the tank 241-C-106 sludge.

During the operational phases of the WRSS process (Le., sluicing batches and monitoring periods), a number of process variables are monitored on a continuous basis. These variables include the following:

evaluation is performed. The high cooling rate ventilation system operation for tank 241-C-106 uses the 296-P-16 exhauster, a high flow rate once-through system. A chiller system operates in combination with the cooling coil to supply a constant 4.4 OC (40 O F ) inlet air flow at the air intake.

The fluid handling systems are shut down once the pre-determined amount of sludge has been transferred, or the maximum pump run time is reached.

During the retrieval phase of the WRSS process, ventilation systems support the waste handling and storage in tanks 241-AY-102 and 241-C-106.

The 296-CW6 venlilation system IS used during the acuvc sluicing phase of the WRSS process

Two ventilation systems are connected to and support tank

A MASS-tron Mass Flow transmitter is installed on the tank 241-AY-102 ventilation system exhaust duct to measure the exhaust gas flow rate. This flowmeter is a microprocessor-based dserential pressure transmitter with optional temperature andlor static pressure density compensation. A direct temperature reading can be obtained from the MASS-tron Mass Flow transmitter. A second means of measuring the exhaust air temperature is by a resistance temperatuie detector (RID) (TI-AY2K48-1B) located between the ventilation cooling system condenser and moisture separator upstream of the flowmeter. This temperature will be recorded by the project data acquisition system. An in-tank imaging system is provided for tank 241-C-106 by project W-320. It provides real-time viewing of the tank's interior during sluicing operations andlor monitoring periods, whenever headspace visibility conditions permit.

The imaging system sliares the riser assignment with the portable exhauster, which is a backup for ventilating the tank in !lie event the main ventilation system fails.

This parameter is displayed in the MO-211 control room and can be monitored to control solids loading during a sluicing batch.

The pump curve correlates the pump speed, discharge pressure, and flow rate. The pump speed and flow rate parameters are displayed in the MO-211 control room.

The minimum pump speed of 1,500 rpm is required to maintain the level of lubrication specified by the pump manufacturer.

To start sluice batch 1.1.1 (see Figure 3 - 9 , the P-1361 submersible slurry pump is positioned so that its low-level detector is located at 178 cm (70 in.). Tlie P-062 VP-0622 sluice pump system is then started and the flow rate is adjusted to a nominal 1,325 L h i n (350 gdmin). Once the sluicer flow is verified in tank 241-C-106, the sluice stream is aimed towards the region of the P-1361 submersible slurry pump intake. The P-1361E'-1362 slurry pump system is started next, and the P-1362 slurry booster pump speed is set at a nominal 1,624 rpm.

The P-1361/P-1362 slurry pump system is started next, and the P-1362 slurry booster pump speed is set at a nominal 1,624 rpm.

The operator adjusts the position of the sluicer nozzle, which is normally set in the semi-automatic operating mode, to gradually increase sluicing efficiency to produce a slurry stream containing 0 weight percent to 10 weight percent

A minimum of 15 minutes before the scheduled shutdown of a sluicing batch, the operator raises the submersible slnny pump level and directs the sluice stream to the area of the submersible sluny pump intake to dilute the solids entering the pump. At the nominal 1,624 rpm sluny booster pump speed setting, approximately 1,325 L/min (350 gal/min) of relatively solids-free solution is used to flush out the slnny transfer pipeline. After at least one-and-a-half pipeline volumes (i,e,, 6,400 L [1,690 gal]) of relatively solids-free solution have been transferred, the sluice pump system and slurry pump system are shut down. During the first sluicing campaign, the tank 241-(2-106 liquid level will be controlled to maintain a hydrostatic head in the tank needed for sludge temperature control. For sluice batch 1.1.1, this liquid level limit is greater than 178 cm (70 in.) of waste in the tank.

To ensure the liquid head on the sludge in the tank is not lowered below the established limit during each sluice batch of the first campaign, the pump winch is locked out to fix the elevation of its lower liquid level sensor. At startup, the tank 241-AY-102 operator will try to maintain the tank 241-AY-102 liquid level constant by monitoring the E M m level gauge and adjusting the P-0622 sluice booster pump speeds. The operator will have to take into account the approximate 8,500 L (2,250 gal) hold up in the transfer pipeline system. The level in tank 241-C-106 is verified during sluicing by the absence of the submersible slurry pump level low-level alarm, which is interlocked to shutdown P-1361P-1362 slurry pump system when activated.

The liquid level in tank 241-'2-106 is controlled during all phases of the WRSS process to minimize the potential for a tank leak. At all times during the process, controls will be

3y integrating the product of the sluny solids loading and ;luny mass flow rate overtime, the total mass of particulate ;olids transferred during sluicing can be calculated. This mameter is displayed for the current increment in the MO- 11 1 control room and can be monitored to control sluicing to he mass transfer limit. f ie MO-211 control room provides a direct readout of remaining pump run time during a sluice batch based on the above algorithm. Mer the pump run time limit is reached (12 hours or less), the sluny pump system must be shut down. As indicated in Section 4.1.1, the shutdown procedure begins a minimum of 15 minutes before the scheduled pump shutdown to allow time for performing a solution flush of the sluny pipeline.

Process supernatant flushing of the slurry pipeline is done routinely to prevent the buildup of solids in the sluny line. tn addition, if abeginning solids buildup is identified during process monitoring, one of following two flushing operations would be undertaken to correct the problem.

Both the sluice and sluny transfer lines can be water-flushed from the tank 241-AY-102 end using flush connections in the sluicing system jumpers, located in the 241-AY-02A (slurry distributor) pit and 241-AY-OZE (sluice pump) pit. Cover block shielding plugs are first removed from the AY Farm pit cover blocks enabling access to the flushing port blank. The blank is removed and a flushing adapter jumper is attached in its place. Water from a tank truck is pumped through the transfer line to achieve the required flush.

Therefore, the best results are obtained if the densitometer measurement is made immediately after completing each batch when the highest possible fraction of solids is still suspended.

Grab samples are obtained from the tank to refine the estimated amount of tank 241-C-106 sludge that has been transferred and to estimate the radiogenic heat associated with the sludge. Section 4.6 discusses the process control sampling requirements and schedule in more detail. A density profile of tank 241-AY-102 is obtained with a lap-top computer that connects to the Communication Interface Unit (CIU) located in the 241-AY-801 building

Using the patable computer, the operator enters commands to lower the displacer into the waste to obtain a density profile.

In generdting a density profile. density nieasurements are maie in 30.5cm (12 h.) inaements referenced to an elevation of 193.87 m (636.07 A) or 3.96 m (156 in.) above the tank bottom. After the first sluicing batch of the campaign, density profile measurements will start at the 3.96 m (156 in.) waste level and descend in 30.5 cm (12 in.) increments until neutral buoyancy is achieved. When the tank241-AY-102 waste level begins to increase during subsequent batches, the starting elevation for the density profile measurements indexes in 30.5 cm (12 in.) increments. The number of ascending increments depends on the new supernatant surface elevation. However, no density measurement is to be made at less than 15.2 cm (6 in.) below the waste surface to ensure total submergence of the ENRAFm displacer.

If waste stratification occurs, then waste homogenization operations can be performed in tank 24 1-C-106 to more uniformly distribute the heat load. Therefore, the primary measurement method for determining mass transfer for each sluicing batch will be the E M m densitometer. The mass flowmeter will provide backup measurement in case substantial solids settling occurs before ENRAFm measurements can be made or in case of densitometer instmment problems.

Before the next sluicing batch is started, the value of Mhold is set equal to either the mass of paaiculate solids transferred during the current sluicing increment or zero (0) for the start of the new increment. The net particulate solids mass reading (Mplc) on the mass flowmeter net flow computer is also reset to zero (0) at the beginning of every batch.

All operable thermocouples on the thermocouple trees installed in risers 8 and 14 of tank 241-C-106 are monitored on a continuous basis to determine the waste temperature

The minimum number of operable tank 241-C-106 thermocouples required for the WRSS process is one bottom thermocouple on either the riser 8 or riser 14 thermocouple tree and one dome space thermocouple. This baseline is initiated following the start of tank 241-C-106 waste subcooling operations and continues concurrent with the cooling operation until the start of sluicing. The newer restrictive limit of Administrative Control 5.26 requires waste temperatures to be at wintertime temperature, thermocouple 1 on riser 8 thermocouple tree -64 “C (148 T) Table 4-4 presents the in-tank thermocouples that will be monitored during all sluice batches of the WRSS process and the waste temperature limits that apply for the batches making up each of the planned sluice increments.

A recovery plan is to be prepared, approved and implemented immediately to restore the waste temperatures to within limits. The tank 241-C-106 in-tank thermocouples will continue to be monitored and recorded during monitoring periods following each sluice batch.

Also, the tank 241-C-106 liquid level will be maintained to comply with applicable limits during the monitoring periods.

Before the liquid level control limit is lowered for the next sluice batch, the monitoring period must be long enough to increase the subcooling margin so the pre-sluicing subcooling margin will be maintained when the supernatant is lowered to the desired level.

During sluicing operations, sludge temperatures (using the existing in-tank thermocouples and MIT) and insulating concrete temperatures will be monitored and the observed temperatures correlated with heat balance data provided by ventilation system aifflow rates, temperatures, and humidities. Ventilation of the tank 241-AY-102 primary tank and annulus during all sluicing operations will be provided by the 241-AZ-702 and 296-A-16 systems, respectively.

The thermocouples and MIT in tank 24 1-AY-102 (see Table 3-9) will be continuously monitored throughout the sluicing operations to ensure that actual thermal behavior remains consistent with the estimated temperatures predicted by project thermal analysis (Ogden et al. 1998). The minimum number of operable thermocouples required for the WRSS process is one tank dome space thennocouple, one supernatant thermocouple, one sludge thermocouple, the MIT validation probe, and six insulating concrete thermocouples (E-102-1, -3, -6, -10, -14, and -24). !.fat any time the sludge temperature profiles indicate a significant adverse departure from the estimates, sluicing operations will be suspended to allow for further analysis of the tank conditions and to restore waste temperatures within allowable limits.

Requireinelit or lnihatirig Statement

The level rise refers to the increase in the waste level staaing from the waste level immediately after completion of a campaign. This measurement must be obtained using hourly E M m data, and the baseline must be established when the potential surface motion and intermediate foaming stop (within 1 day of completion of campaign). The hydrogen concentration inthe tank 241-AY-102 dome space must be baselined before the statt of the first sluicing batch (1.1.1). If significant gas retention is observed or if there is excessive uncertainty in the estimates of retained gas inventory, a void fraction measurement is required. During all phases of the sluicing process, leak detection instrumentation is monitored to alert operators to the presence of a leak in the WRSS equipment. Alarm functions on the leak detection instrumentation allow timely identification of a potential leak so recovery actions can be taken to mitigate the consequences of a leak. Leakage from tank 241-C-106 will be determined using a combination of liquid level measurement, d q well measurement, and material balance estimates.

M e r shutdown of the slnny pumping system at the conclusion of a sluice batch, a minimum liquid level is reestablished in tank 241-C-106 thatjust covers the solids within the sluice zone. At the completion of a sluice batch, the E M i M gauge will be lowered immediately into tank 241-C-106 and placed in the liquid level monitoring mode. Collection of level data will begin once the gauge is placed in senice. A 24 hour

baselining wnod \\ill be required to allow the dynamics of the proce&-to subside (e.g.,sluny and sluicing transfer pipeline draining, solids wetting, and fog reduction). Once tlie baseline is established, the trend in the liquid level will be monitored and recorded.

For single-shell tanks equipped with an E M L M level gauge that measures a liquid surface, the leak detection criteria is that a -1.3 cm (-0.5 in.) change in liquid level will prompt a leak investigation (LMHC 1996). This same criteria will apply to tank 241-C-106 during the WRSS process monitoring periods.

When liquid level monitoring of tank 241-C-106 is in process during the monitoring periods, video recording of the wall area of the tank using the in-tank imaging system will be required once per day. If this sloughing occurs or other liquid waste additions are made to the tank (e.g., pit flushes, ventilation filter flushes, or pipeline water flushes), a new baseline will have to be established for purposes of leak detection.

Both a batch material balance and a cumulative material balance will be kept during the WRSS process to monitor the progress of the sluicing operations and to provide a secondary indication of a potential leak from tank 241-C-106.

Actual waste volumes in tanks 241-C-106 and 241-AY-102 are obtained from the E M m level gauge measurements.

The data required to perform the cumulative material balance calculations are listed below. 0 liquid levels in tanks 241-C-106 and 241-AY-102 at

To confirm that the oil interacts as anticipated during the WRSS process, the supernatant surface in tank 241-AY-102 ,vi11 be sampled periodically. 3ne sample will be taken following each of the increments. 4dditionally, the surface of the waste will be inspected for m oil slick during monitoring periods using the mobile color :amera system.

All sampling events will be made from the same location at riser 15-N.

[f the calculated pre-sluicing subcooling margin is reduced at any time during the sluicing operations or if sluicing shutdown is anticipated to extend beyond 20 days, ventilation of the tank will be aligned to operate the 296-P-16 exhauster and the inlet air chiller system. Air cooled to 4.4 “C (40 ”F) will ventilate the tankuntil sluicing start up is desired and the required subcooling is achieved. The response to this off-nomal event is applicable only for the first campaign. The response to the off-normal event where the predicted tank 241-AY-102 steady-state temperatures exceed the LCSLCO 3.3.2 limits because a high total heat load is as follows. 1.
