l 3.2. P'RdCESS PARAMETERS 3.2.1 PROCESS DESCRIPTION Prior to the first soldification of a particular type of.

radioactive waste in a full-size container, process con-trol' verification test (s) will be performed. The purpose of the verification test (s) will be to determine the proper quantities of cement, and additives required to be placed in each 55 gallon drum. The verification test (s)

- will also indicate the required amount of pH additive required to be.added to the waste tank to insure the proper pH is obtained.

Once a satisfactory verification test has been performed, the radwaste operator will begin the salidification evolution. The required quantities of additives will be placed in the 55-gallon drum prior to placing the

.a container on the drum conveying system.

s Once the additives have been placed in the container, the container will be placed on the drum conveying system and moved to the cement fill station, where the required quantity of Portland Type III cement will be placed in the drum. A mixing weight will be placed in the drum following concrete addition. The drur. conveying system will then move the cement-filled drum to the loaded drum storage area.

The installed overhead crane system will transfer the cement-filled drum to the radwaste fill station where the wet radioactive waste will be metered into the drum. Th'e drum will then be placed in the drum tumbler and tumbled for the required time.

3.3 DETAILED SYSTEM DESCRIPTION

3. 3.1'

' CEMENT. STORAGE SYSTEM DESCRIPTION The STOCK' solid radwaste system for WCGS begins.with a cement filling system for onsite storage of large

. quantities of' cement as well as the control equipment and instrumentation to accurately-transfer measured quantities of cement to standard 55-gallon drums. Although the entire cement filling process is carried out in safe areas of.the plant, the equipment has been precision' engineered for dust-free operation so that no cement dust will enter the plant atmosphere or cause deposits on the outside surface of the drums which might subsequently become

(

contaminated.

The entire cement. filling system is operated from its own control console' located adjacent to the cement filling station and the conveyor system. Controls, monitoring devices and alarm indicators have been centralized-in this location for ease of operation and to keep the operator informed of system status and operation.

Incoming cement is transferred into the. storage silo utilizing the fluidizing equipment and blowers mounted-on the cement delivery truck. Cement is again fluidized and transferred in small increments on operator command to the inside cement filling station day tank as needed. Mounted above the day tank is a dust collection system interconnected to the day tank, the drum feeder assembly-fill nozzle and to the storage silo to maintain vacuum conditions and dust containment at all times.

Standard 55 gallon drums from a clean storage area enter the cement filling station on a STOCK roller conveyor and are individually positioned beneath the cement fill nozzle. A predetermined amount of cement is placed into each drum by the action of a screw feeder located at the Rev. 4 1-5 6/86

day tank. discharge. hopper. EThe weight of cement ' per. drum

'c

.is determined in.accordance with.the process sample:

f /\\

verification which is performed on each batch of b

radioactive waste to be processed.-

Once' a drum has been filled with cement and sealed, it 'is

-conveyed to-the drum staging area for pickup by.the' bridge crane..The crane may transfer the drum either to a drum-storage area or to the drum processing: enclosure where the decanting and drumming equipment remotely apply measured quantities or specified proportions.of radioactive-slurries and concentrates.

An air' compressor system.is included in the cement filling system and is housed in an environmentally-controlled room-located,at the base of the storage silo to provide process air free of oil and water contaminants. STOCK-supplied transfer piping supplies air to the pneumatic conveyor, the fluidizing jets in both the silo discharge zone and in-the day tank discharge hopper, the automatic filter cleaning equipment in the dust collection' system, the bell-type shut-off valve in the cement fill nozzle orifice and to the air-oil cylinder operating the drum scale platform.

~ The cement filling system performs a number of related functions :

inspection of drums.and caps for damage and

-proper; thread line, long-term storage of large quantities t

of cement under controlled conditions, application of the specified quantity of cement and the mixing weight to the

-drum, recording of drum tare weight and filled weight and drum sealing. It is recommended that a drum control number be assigned to each drum and recorded, and that a

-label or stencil be applied to the drum head in this safe location.

Numbering will facilitate positive identification for a:

subsequent process control; therefore, the labels or stencils used should be of sufficient size and contrast to permit viewing by means of the traveling bridge crane grab TV and surveillance cameras located a considerable distance above the drum storage. area. The cement filling system han been provided with the following systems and components.

3.3.1.1 Cement Storage Silo The cement storage silo is of cylindrical construction with a dished head and conical discharge section, fabricated from 1/4" ASTM A-283-C steel. Double-welded construction O

Rev. 4 1-6 6/86

throughout assures dust-tight integrity and-vacuum maintenance.. Storage capacity is 1,530-p}._ :

cubic feet of cement.

The silo is' filled from self-unloading delivery trucks through a-4"~ diameter fill line. The' fill line includes a clean-out port at its highest

~

elevation and.is connected to a discharge box centered on the top of the silo.- The discharge.

box allows the cement lto fall evenly inside'the

~

tank during filling.

Also located at the top of the silo is an ins'pection manhole and a 5" diameter vent line which is connected to the dust collection system-located on the cement filling station day tank.

Access to the top of the silo is provided by a

. hand. ladder with safety cage and a maintenance-platform with ' perimeter railing-all designed and -

constructed to OSHA standards.

e Cement is discharged from the bottom of the silo to a pneumatic conveying system. The pneumatic conveying system is mounted to the inlet chute.

The pneumatic conveying system connecte to the cement silo via a du'st-tight inlet chute and a manually-operated shut-off valve. The sides of 1' p the discharge cone of the silo directly above the

'Q.

shut-off valve are sloped at a 500 angle from horizontal. Ten automatically controlled air fluidizing nozzles are installed in the perimeter of the-discharge cone to prevent packing of the cement powder.

3.3.1.2 Silo Pressure Relief Valve A. mechanical pressure relief valve is mounted at the top of the silo to prevent possible i

pressurization of the silo.

It is set to open at 10" of water and, through a limit switch, energizes a red alarm.

3.3.1.3 Silo High-Level Controls The cement storage silo is equipped with a sonic high-level sensor located at the normally filled level of the silo. When activated by abnormally i

high cement levels, the control energizes two red lights. located at the cement filling station electrical console and located on the exterior wall of the silo.

U 3.3.1.4 Silo Cement-Level Indicator j'

A mechaaical level indicator.is-provided for 1

monitoring the amount of, cement remaining in the silo.

A 4-figure digital readout located in the air compressor room displays in tenths of feet the level of cement remaining in the silo.'

3.3.1.5 SilohiuidizingSystem Transfer of cement from the storage silo to'the air conveyor equipment is facilitated by an air

. fluidizing system..The air fluidizing system consists of an air filter with automatic drain, 4

an accumulator tank for air storage, a pulsator motor with cycle timer and ten fluidizing nozzles. The nozzles are deployed at various

~

!~

levels around the perimeter of the silo discharge cone.

f All nozzles are connected by a common manifold to a pulsator solenoid valve located next to the silo discharge cone downstream of the accumulator 1

tank. The cement conveying system controls are interlocked to the fluidizing system, pe,rmitting n pulestor motor and cycle timer to open for several brief intervala before the start of each i

3 I

conveying cycle. Short bursts of high pressure air through the fluidizing nozzles aerate the cement in the discharge cone area of the silo facilitating its passage to the cement chute for controlled application to the fluidizing vessel.

I 3.3.1.6 Air Compressor System i

An air compressor system is installed in a i

separate room attached to the base of the cement storage silo to supply process air to the cement filling system. The pneumatic equipment is an i.

independent and self-contained system including t'

Rev. 4 1-8 6/86

all necessary components to provide the' required delivery of air for the cement filling system-q/ '}.

free.of any oil or water contamination. 'The air T _/1 system is equipped with two air compressors, s

7 coalescing filters, air dryers and pressure regulators..

3.3.2 CEMENT FILLING SYSTEM The cement filling system includes all the equipment necessary to transfer cement from the storage silo into the drum. The four principal items of equipment are: an air conveyor unit to transfer cement to the day tank, the day tank, a screw feeder assembly which precisely meters the applicaton of cement into each drum and a dust collector assembly designed to remove the cement dust generated at each point in the process.

3.3.2.1 Air Conveyor System An air conveyor system is utilized to transfer cement from the cement storage silo to the cement day tank. The system has an operating capacity of transferring 150 lbs/1.5 minutes. Compressed air at 80-100 psi (30 SCFM) is required to operate the system.

4 Cement in the silo discharge cone is fluidized by-f-ss

_(

the continuous application of high pressure air.

This allows the cement to drop into the fluidizing vessel of the air conveyor system without packing. Once the fluidizing vessel is filled with cement, unregulated air at 80-100 psi is introduced into the vessel. The unregulated air aerates the cement and causes the pressure in the vessel to increase. When pressure in the fluidizing vessel reaches 15 psi, the unregulated air is stopped. Regulated air then forces the aerated cement from the fluidizing vessel into the transfer line. The transfer line is connected to the day tank. The regulated air forces.the cement in the transfer line into the day tank.

The conveying cycle is complete when the transfer line is empty.

3.3.2.1.1 Air Conveyor Booster Jet The air conveyor discharge piping into the day tank contains a pneumatic booster jet to impart additional accelerating force and mixing action Rev. 4 1-9 6/86

service valve.

3.3.2.1.2 Conveying Fault Timer The conveying fault timer is included to automatically stop the conveying process if a batch of cement is not completely evacuated from the fluidizing, vessel to the day tank within a specified interval.

3.3.2.2 Cement Filling Station Day Tank The day tank of the cement filling station is located inside the radwaste building and is designed to hold sufficient cement for one day's operation. The tank has a net storage capacity of 50 cubic feet. The air conveyor system is capable of filling the day tank in 1.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />.

The day tank is rectangular in shape with all four sides tapered sharply into an integral discharge hopper. The entire assembly is fabricated from 1/4" ASTM A-283-C steel utilizing double-welded construction for strength and dust-

'g-A( )

tight integrity. The tank itself and equipment mounted thereon is accessible by a welded steel-service ladder and a bar-grating maintenance platform surrounded by OSHA specified double handrailing.

I Fluidized cement from the air conveyor enters the day tank through a discharge box which distributes the cement evenly inside the tank.

The day tank is equipped with a mechanical pressure-relief valve. The pressure-relief valve is set to open at 10 inches of water to prevent the possible over pressurization of the day tank.

A sonic high-level sensor located at the normally filled level of the day tank provides indication of day tank level. The day tank has sufficient capacity to complete the transfer of a batch of cement should the high-level set point be reached during transfer. The day tank is equipped with an interlock to prevent the transfer of cement to the day tank once the day tank high-level alarm 1-has been reached.

The screw feeder ' assembly is used to transfer" cement from the. day tank discharge hopper to the-fill nozzle..The fill nozzle is.placed inside the 55 gallon drum. The screw feeder consists of a tapered, rolled, steel screw driven at 25.7 rpm. This provides a cement delivery rate of 110 cubic feet per hour.

The screw feeder discharges'to a vertical exit-hopper. The drum fill nozzle is attached to the

+

base of the exit hopper.1.The walls of the' exit

' hopper are installed at a steep angle-to prevent the accumulation of cement in the exit hopper.

'3.3.2.4 ~ Dust Collection System A Torit filter cartridge-type' dust collector is

. installed'with the cement filling system to

ye~x.

provide vacuum conditions within the system and

(

to eliminate area contamination from airborne cement dust.

3.3.3 DRUM CONVEYING' SYSTEM-The drum conveying system consists of the roller conveyor O

used to transport drums through the cement filling station area and the integral lift assembly and scale platform which raise the drums to the cement fill nozzle for filling.

3.3.3.1 Roller Conveyor.

The roller conveyor is divided into four distinct sections. The first section is a flat drum staging area seven feet in length for drum

[

inspection, numbering and cap removal. The i

second section is the scale platform and drum lift area which hydraulically elevates one drum at a time for filling and weighing. The third section is a long, flat receiving area for inserting the mixing weight and replacing the cap. The fourth section is a floating storage area approximately 22 feet in length for conveying filled drums to the traveling bridge crane pickup point. The length of the storage area is designed to hold enough prefilled drums for one day's normal needs.

1 3.3.3.2.' Scale Platform A scale platform is installed for weighing I

individual drums.

It is located beneath the elevating section of'the roller conveyor. It consists of three 500 pound capacity load cells.

The outputs of the three cells are added by the load cell summing junction in the electrical.

o console and the. total is displayed on one of two LED-type, three-figure digital readouts on the electrical console. The readout labeled DRUM' TARE displays the weight of the empty. drum when the scale platform is in its lowered position.

This tare weight is retained in a memory circuit of the electronic weighing system. The readout labeled DRUM NET displays the continuously changing net weight of cement as it is being injected into a drum.

When the desired net weight of cement is reached and the feed screw is deactivated, the operator will depress the CLEAR TARE pushbutton on the electrical console. This allows the tare weight

=

to be added to the net weight of cement. This is the net weight'of the drum.

3.3.3.3 Mixing Weights The mixing weight is a reinforcing bar bent at its midpoint to an angle of approximately 120 degrees. At least one mixing weight will be inserted into each drum at the cement filling station after the cement has been metered into

'the drum. While the drum is tumbled, the weight (s) imparts mixing action to its contents in the drumming operation.

3.3.4 CEMENT FILLING STATION CONTROLS The electrical control console contains all controls for operating the cement filling station. The controls and instrumentation are located at various points in the console and are listed below by area.

provided to allow for ease of operation and to inform the operator of station status and operation.

O Rev. 4 1-23 6/86 3

, /,_

solid radwaste system to accurately decant slurries prior

).

to drum filling.. This station is a compact assembly of-

\\s_,/

components attached to both sides of a 12" thick steel shield. wall. Mounted on the maintenance side of the shield wall-are all motors, pneumatic valves, actuators and as many of the gear reducers as is practical. On the-process side of the wall are the decanting tank and the pumping ends of the metering and decanting pumps.

Incoming waste slurries are transferred from the liquid radwaste system storage tanks to the decanting tank through the piping manifold. During this filling operation, the decant tank mixer is automatically operated to ensure that the slurry is a uniform mixture. Upon completion.of the filling operation, an automatic flush operation is initiated to flush the fill line to the decant tank and the feed line back to the liquid system storage tank. After this flush operation has been

' completed, the slurry is allowed to settle for a predetermined period of time. This settling time allows for the separation of solids and water to a uniform level bed-of-solids.

Once this settling period has elapsed, the water level and water-solid interface level are accurately measured with sensors mounted on the decanting arm and STOCK designed solid state equipment. These readings are displayed on (g) the control console and inform the operator as to whether excess water is to be removed or if water is to be added to the decant tank. This is done in accordance with the process control program in order to achieve the correct solid / water ratio consistent with the pretested solidification formula for the waste stream. Excess water is removed with decanting equipment and returned to the liquid radwaste system storage tanks by means of a specially designed decanting pump. This minimizes the amount of water requiring disposal.

Af ter the decant tank has been prepared with the correct solid / water ratio, the mixer is then automatically started and operated for a predetermined period of time to ensure that the slurry is again uniform. While the slurry is being mixed, the operator is then able to record the radiation level of the slurry to be processed with the radiation detector provided with the decanting station.

The STOCK metering pump is used to transfer the prepared decant tank slurry to the drumming station for drum processing. The pump and its associated controls allow the operator to program accurate pump quantities to be O

circuits. Complete monitoring of operation of the drumming station can be accomplished by watching the graphics display panel while the drumming station is in use. The operator has the option of drumming either-decanted wastes or concentrator wastes-as well as any combination of the two.

-The drumming station is a compact assembly of components to drum radioactive slurries and solutions in SS gallon drums 5dth cement solidification binder. For safety in operation and for maintenance, the equipment is attached to both sides of a 12-inch thick steel shield wall.

On-the safe side of'the wall are mounted all motors, pneumatic. valves, actuators and as-many of the gear reducers as is practical. On the hot side of the wall are

'r's; the pumping ends of the metering pump and the drum

(( j' processing enclosure. The 12-inch thick steel shield wall provides the equivalent of 39 inches of concrete

~

shielding, allowing personnel to be present on the safe side of the wall during operation for maintenance or for other purposes.

The drumming station is remotely operated from the console which is provided with the control station. Controls and-monitoring devices have been provided to allow automatic or manual operation and to inform the operator of station status and operation.

The drumming station allows drums to be filled with either evaporator concentrates or resin slurries. Prior to drumming operations process control verification. tests are performed in accordance with the requirements of the process control program. Once a satisfactory verification sample has been performed, the required quantity of waste is programmed into the waste meter pump controls. The metering pump will automatically transfer the required quantity of waste to the disposal container.

Upon completion of the automat!ic process cycle,.the drum is returned to the load / unload position within the drum

-processing enclosure. The operator then' initiates remote opening of the hatch and lowers the crane's drum grab into the enclosure. The drum grab is equipped with a downward viewing camera, which allows the operator to inspect the drum.

After the operator has verified that the top head'of the drum is free from contamination, he then raises it out of A

the drum' processing-enclosure and positions it upon the scale platform. Once the drum has been released, the drum's weight and radiation level:are then measured and recorded. Displays for these functions are provided'at the control console and provide valuable information as to the decay pit and location at which the drum should be stored.

All piping used to transfer the concentrates to the solid radwaste drumming station and for recirculation of the bottoms tanks is heat traced to prevent crystallization of the concentrates prior to reaching the solid radwaste drumming station. The solid radwaste drumming station also receives f

s[

liquid waste from the chemici drain tank.

3.9.3 The primary and secondary bottoms tanks and the chemical drain tanks are equipped with recirculation capability to insure satisfactory samples may be obtained and analyzed.

3.9.4 The installed resin sluicing system transfers spent resin and depleted charcoal to the spent resin storage tanks (primary and secondary). Resin slurries are then transferred to the solid radwaste decanting station. The solidification system operator can maintain the required amount of liquid in the resin slurry and decant and transfer all excess liquid to the spent resin hold up tanks.

3.9.5 All exhaust from the decanting station and the solid radwaste drumming station is processed by the radwaste building venti 11ation system.

3.9.6 The reactor make up water system is used to wash down and decontaminate processed drums as necessary to remove external contamination from the drums due to spillage.

3.9.7 The installed bulk waste disposal station provides necessary interface support for mobile vendor processing systems; the discharge header includes primary / secondary Ov Rev. 4 1-31 6/86

~

resins and concentrates supply;-the return header provides a return route for decanted water resulting from resin

(~'h1 slurries. Both lines are tied into the reactor makeup

' \\,_j water _(mfW) system for backflushing capability.

3.10 CORRECTIVE ACTIONS 3.10.1 At predetermined intervals a portion of the solidified containers will be inverted and allowed to stand for a period of time. Each of these containers will then be inspected for free standing water. The results of each inspection shall be recorded. Should any container be found to exhibit free standing water greater than the FSW criteria established by the low level radioactive waste disposal facility, the following actions shall be taken:

3.10.1.1 Secure solidification activities until new solidification ratios can be determined and proven.

3.10.1.2 Inspect all available containers from the same batch of radioactive vaste solidified using the formulas which provided the unsatisfactory results.

3.10.2 Drums that exhibit free standing water shall either be dewatered or reprocessed by determining the quantity of gs water and adding proper quantities of cement and additive v) chemicals as required by a sample verification test.

(

4.0 ADDITIONAL PROCESSING 4.1 VENDOR PROCESSING 4.1.1 In the event that WCGS requires vendor processing capacity, KG&E shall use vendor processing to ensure that LLU produced at WCGS is efficiently processed for shipment in accordance with NRC, DOT and state burial requirements.

4.1.2 When vendor solidification, resin dewatering, or filter encapsulation services are used at WCGS the latest revision of the NRC approved vendor process control program shall govern the applicable LLW processing whenever this service is in use.

4.1.3 Low-level radioactive waste processed by vendor systems shall be certified as complying with the free standing liquid requirements for licensed shallow land disposal sites.

5.0 FILTER DISPOSAL IN HIGH INTEGRITY CONTAINERS (HIC'S) 5.1 ADMINISTRATIVE CONTROLS 5.1.1 Filter cartridges produced at WCGS that are in excess of.1 uCi/cc specific activity containing radionuclides with half-lives greater than five years shall either be encapsulated in accordance with step 4.1.2 or disposed of in approved high integrity containers (HIC's).

5.1.2 When HIC's are used at WCGS for filter cartridge disposal, each polyethylene HIC ordered shall be pre-foamed on its interior to preclude any container damage during packaging handling and transportation to a burial facility. Metal alloy HIC's will not require interior pre-foaming.

5.1.3 Filter packaging and disposal shall be done in conformance with the latest state-approved certificate of compliance.

WCGS shall obtain the C of C onsite prior to any waste processing.

5.1.4 KG&E shall insure that the maximum allowable free standing liquid in a high integrity container is less than one half percent (0.5%) of the waste volume.

5.1.5 Qualified test data s'upporting compliance with the free standing liquid requirements in 10CFR61 for the WCGS f~s

(

)

filter disposal method are contained in Appendix C.

Vendor certification statements for mechanical filter cartridge compatibility with identified HIC's are contained in Appendix D.

5.2 FILTER DESCRIPTION AND TRANSFER 5.2.1 Spent filter cartridges that normally require disposal at WCGS are Pall-Trinity cartridge filters. The Pall-Trinity cartridge filter contains fiber filter media rigidly enclosed in a stainless steel mesh cylinder housing. The plant Pall-Trinity seal water injection filters are 2-3/4" (inches) in diameter and 19-1/4" (inches) long; the remaining plant Pall-Trinity filters are 6" in diameter and 16-1/2" long.

5.2.2 The spent filters are first valved out of service, then vented and drained by the use of remote valve operators.

The filter housing is unbolted and opened using long handled tools. The filters are then removed manually using a long handled hook or remotely using a shielded filter transfer cask (FTC) depending on radiation levels.

v Rev. 4 1-33 6/86

5.2.3

'Ite filters are then transported to storage and placed into a high integrity container (HIC) if the estimated activity is equal to or greater than 1 uCi/cc of isotopes (m

with half-lives greater than five years averaged over the i-volume of the filter.

5.2.4 Other filter cartridge types utilized at WOGS include de-sludging Cuno type cartridge filters (2" in diameter by 14-3/4" long); respirator trailer and ultrasonic turbulator Cuno type cartridge filter (2" dia. by 10" long); and a respirator trailer Gelman Acroflow II cartridge filter (2" dia. by 10" long). These filters are changed out manually and placed in plastic bags or other suitable container and transported for placement in a HIC, if the filters are determined to contain in excess of 1 uCi/cc of isotopes with greater than five year half-lives.

5.2.5 Spent cartridge filters produced at NOGS shall be classified according to 10CFR61 and have curie content determined per procedures HPH 09-501 and HPH 09-502, respectively,'or by NRC approved computer software.

5.3 HIGH INTB3RITY CONTAINER DESCRIPTION 5.3.1 Spent filter cartridges produced at WOGS are placed into two different types of HIC's.

The first type is constructed of polyethylene:

the second type is (Q) constructed of a metal alloy (Ferralium 255). Both containers have undergone full scale testing and are designed to comply with the structural stability requirements of 10CFR61.56.

5.3.2 HIC's used for filter cartridge disposal at WOGS have been certified as being resistant to the identified filter cartridges and their contents, including the water absorbing agents.

Refer to Appendix D for certification of compatibility statements between WCGS filter types and identified HIC's.

5.4 FILTER TREAMENT METHOD 5.4.1 Prior to the addition of the filters to the HIC, the bottom of the container is filled with approximately 6" of vermiculite or Aquaset agent. Following each filter addition, a minimum of one gallon of vermiculite or one-half gallon of Aguaset is also added to the HIC. The amount of agent added has been determined to provide a conservative amount of absorbent to assure at least twice the amount necessary to remove residual filter liquids within the HIC.

5.5 FILTER' TREATMENT DETERMINATION I

!m..

\\

\\s_,/~

5.5.1 The previously described treatment method was determined to be adequate to meet regulations and burial ground requirements by' measurements 'made. at WCGS.. Each type of.

filter was weighed dry then immersed overnight in water.

~

.The filters were then removed and weighed to determine the maximum water retention (the results are contained in Appendix C).

5.5.2 The Vermiculite'and Aquaset agents were tested to determine the quantity required to absorb' a known amount of liquid. The ratio was determined to be 2.5 parts Vermiculite to one part water. For Aquaset, this ratio was determined to be one part Aquaset to one part water.

5.5.3 Since the maximum amount of water that could conserva-tively be estimated to be present in a filter at WCGS is 627 m1,'the required amount of Vermiculite would be 1568 m1, or 627 m1 for Aquaset. -Since the burial facilities dictate that twice the amount of absorbent required to fully absorb liquids be added, 3136 m1 of Vermiculite or 1254 al of Aquaset should be added. Therefore, a one gallon (3785 ml) addition of Vermiculite, or a one-half i

gallon (1893 ml) addition of Aquaset, for each filter packaged is a conservative amount'to assure package free gs standing liquid restrictions are. met.

The preplaced 6" of 4

absorbent is for conservatism.

In response to your June 11, 1986 letter, hUS Process Services does have hioh integrity containers (HIC's) which can be used tot disposal of the filter cartridges produced at the holf Creek Generatino Station. Those HIC's are produced by IFC Nuclear Associates, Inc. and they are licensed for use at the Barnwell '

radioactive waste disposal site. A copy of the state certificate ot compliance and a glyer describing the HIC are enclosed for your review..

i l

filter encapsulation liner. Inis liner encapsulates the filters In addition to the TFC HIC, NOS Process Services offers a j [

'('j with cement and is acceptable at the Barnwell and Richland burial sites. This liner also serves as a self shield and can be used for spent tilter storage when the filter generating rate is low.

hUS Process Services is also in the process or licensino a new HlC that will meet the burial recuirements at all waste disposal taltes. We expect to have that HIC available early in 1981.

We have several methods available tor disposino of your cartridae filters and we stand ready to provide the best one for i
