The system is designed to deconta-minate, by filtration and ion exchange, radioactive waste water contained in the Auxiliary Building or Fuel Handling Building of TMI Unit 2. Contaminated water will be punped from a connection located on the miscellaneous Waste Holdup Tank (WDL-T-2) by a pump located in the Chemical Cleaning Building through the yard and into the process system, or it will be obtained from the Monitor Tanks SDS-T1A/TlB, or l l L l

3 Reactor Coolant Bleed Tanks (RCBT's). Yard piping will be shielded and enclosed within a guard pipe, the open end of which terminates inside the Chemical Cleaning Building. The primary process system consists of a prefilter and two demin-eralizers connected in series. Waste liquid is transferred from the Source Tank (MWHT, RCBT, or SDS-TIA/TlB) through the prefilter and demineralizers, to the Clean Water Receiving Tank (CC-T-2). Change-out Criteria for the various units are indicated in Table 13 and 14. Processed water will be delivered to the Clean Water Receiving Tank (CC-T-2) for sampling and analysis and either pumped to the Liquid Waste Disposal System of TMI Unit 2, the Spent Fuel Storage Pool, the PWST's, CO-T-1A or WDL-T-98 the truck fill station for discharge if within specs, or transferred to the Off Spec Water Receiving Batch Tank (CC-T-1) for recycling through the process system. The Chemical Cleaning Building (CCB) has been made into a low leakage confinement building and provided with an exhaust ventilation system to maintain the building at a negative pressure. Moisture separators, HEPA filters, and charcoal filters have been provided in the exnaust ventilation system in order to filter it before it is released to the stack at the roof line of the CCB. All effluent air is monitored for radioactivity at this point. Provi-sions for grab samples are available. Normal operation of the processing system will be by remote means except for infrequent operations such as sampling, spent resin con-tainer removal and new resin container installation. All remote system operations are controlled from the TV Monitor Control Building

'.cated outside the northwest corner of the Chemical Cleaning Building.

Remote handling of spent resin containers from their position inside the Chemical Cleaning Building to the transport cask and truck is via a remotely operated twenty-ton monorail hoist system. A fire protection system is installed in the HVAC equipment room, the Control Building and the CCB. A new 4" tie-in to the existing fire main supplies a sprinkler system in the TV Monitor Control Building and a hose station in the CCB, as well as the sprinkler line to the air filtration unit charcoal filters. The key to the lock on the valve for this sprayline is kept in the Auxiliary Building Emergency Liquid Clean-up System Control Room which is also known as the TV Monitor & Control Building. Line and grid pressure indication is provided in the Control Building. 4 _._

? The system interfaces with the TMI Unit 2 Radwaste Disposal Miscel-laneous Liquids System, Demineralized Water System, the Submerged Demineralizer System, the Processea Water Storage Tank, the BOP Electrical System, Service Air System, the Unit I Liquid Waste Disposal System, Fire Protection System, the Fuel Pool Waste Storage System, and tne Unit 2 Radwaste Disposal Reactor Coolant Liquia System. NOTE: Although tnere is an interface with the Unit I Liquid Waste Disposal System, the Unit i System will not be used. In tnis respect Unit 11 will function independently. Valve ALC-V169 shall remain closeo (unless transferring CC-T-1 or -2 to tne "d" Spent Fuel Pool) and a spectacle flange is installea cown stream of valves ALC-V169, ALC-V122 & ALC-V123. 1.3 System Design Requirements 1.3.1 Process System Design Requirements 1.3.1.1. Tne process line pipe size is nominally 2" scheaule 40 cased upon tne Epicor Il system flow rate of 10-30 gpm. Otner line sizes are based on service requirements and function, suen as service air, cemineralized water, recir-culation and sampling. 1. 1.2 Pumps ALC-P-1 througn P-4 have nose connections ana are provioed witn arip trays to collect leakage. Orip trays have nozzles as close to the bottom of the tray as possible and are servea oy flexible tubing which leads to the nearest floor or equipment drain using the floor slope to induce flow. Tnis tubing will be placed well down into the floor arain. 1.3.1.3 Remote system operations are airected and controlled from outside of the Cnemical Cleaning Bullaing from the TV Monitor & Control Building. This area is provided with remote closea circuit television monitoring of the opera-ting areas insiae ano outside the Cneoical Cleaning Builaing. 1.3.1.4 Process instrumentation consists of pH, and conductivity i-monitors. Resin Ded, ana pref 11ter radiation levels, process line raciation levels, process flow rates, process totalizers, ano tank levels are also monitorea. Accelero-meters for P-1 tnru P-4 are provided for equipment protection. -

1 I 1.3.1.5 The system tank vents are provided with in line heaters, demister filters, and charcoal filters for adsorption of evolved lodine. These units are sloped to drain demisted liquids back into the system tanks. 1.3.1.6 Liquid waste feed to the system will be drawn from the Source Tank (MWHT, RCBT, SDS-TIA/TlB or CC-T-1) by the first EPICOR II pump (ALC-P-1). The Miscellaneous Waste Holdup Tank pump is not used. This provides better system pressure and flow control. Also, liquid waste feed to the system can be drawn from the RCBT, SDS-TIA/T1B or CC-T-1. 1.3.1.7 Since the Chemical Cleaning Building provides a seismically safe containment, the EPICOR II System and major components are considered to be non-Q.C. scope. 1.3.1.8 All system piping is welded stainless steel except for air piping which is welded carbon steel or copper tubing. Instrument 1.ubing systems are 316 SS Tubing. The instru-ment tubing system is made up using compression fittings. The process system piping is rated at 150 lb. and is designed, installed and inspected in accordance with ANSI 4 831.1 (Power Piping). NOTE: Flanged and screwed connections are used as-necessary on certain components. 1.3.1.9 Capabi31ty is provided to obtain a representative sample of tanks CC-T-1 & 2, and the effluents of Prefilter ALC-F-1 and Demineralizers ALC-K-1 and ALC-K-2, while in a low radiation area in accordance with Regulatory Guide 1.21. Representative sample for CC-T-1 or 2 is here defined as "after recirculating the tank contents for three volume changes". Also the sample line for CC-T-1 & 2 shall be purged to the sample sink for five line voltmes prior to drawing the sample, and for ALC-F-1, ALC-K-1 and ALC-K-2 the sample lines shall be recirculated for five line volumes prior to drawing the sample. NOTE: ALC-F-1, the prefilter is the first deminer-alizer, followed in series by demineralizers ALC-K-1 and ALC-K-2. 1.3.1.10 The building sump shall be a covered sump. 1.3.1.11 System blowdown air and demineralized water lines are provided with individual check valves ALC-V060 thru V079 to minimize contamination of these systm.

1 1.3.1.1z Tne demineralized water supply header is proviaed with demineralized water from TMI Unit 2 in the range of 80-90 psig to meet EP100R 11 requirements. 1.3.1.13 Tne System Air supply header shall be provided with a pressure regulator operating in the range of 80-90 psig, and a moisture separator. An air oiler, and an anti-t reeze injector are provicea for the portion of the System Air header servicing the EPICOR II pumps. Provisions are availaole to connect tne plant Service Air System to the system if necessary. Also two air compressors (ALC-P-7/8) are availaole for use and tie into the air supply header via ALC-V145. NOTE: Ine Plant Service Air System is the preferred air supply. 1.3.1.14 If sampling indicates that the processed water is within limits for oisenarge, the aecontaminaten liquid from CC-T-2' can ce routed to the TM1 Unit 2 Liquio waste Disposal System, the TM1 Unit 2 Spent Fuel Storage Pool, the PWST's or a truck fill hosa connection that is provicea as an alternate means of discharging decontaminated liquids. 1.3.1.15 All system overflow lines shall discharge to the Chemical Cleaning Building sump. All floor crains also cischarge to the sump. The sump pump sends all-collected leakage to the Of f-Spec Water Receiving Baten Tanx (CC-T-1) for recycle tnrough the cleanup system. Ine sump can be directly processed through tne EPICOR II System via existing valving ano pipirg. 1.3.1.16 Since the elevation of the discharge nozzle of tank CC-T-2, ano the Cnemical Cleaning Bulloing floor were fixed prior to oesign ano construction of EPICOR II, the hydraulic design for craining CC-1-2 is not acequate for complete draining of the tank. However, the system was cesigned to facilitate craining to the maximum extent possiole. Final craining of CC-T-2 is accomplisheo with the manual orain line (valves ALC-V131 ano V132). 1.3.1.17 Inree resin traps are installed downstream of tne deminer-alizers. 1.3.1.18 A one micron cartridge type filter is installed downstream of the three resin traps. f 1.3.1.19 The system shall have personnel snielding on various l components to reduce the radiation levels in the operating areas of tne bullaing.

1 1 1 1.3.1.20 A resin trap is installed on the outlet from the casks overflow line to prevent resin carryover into the sump. 1.3.2 Material Handling Design Requirements 1.3.2.1 Normal operation of the Auxiliary Building Liquia Process-ing System is by remote methods. 1.3.2.2 Demineralized water and service air connections are provia-ed to flusn ano blowdown the entire system or portions of it to allow system maintenance. 1.3.2.3 - 4' x 4' casks may De removea f rom the builaing by making use of tne sniela bell designeo for this purpose. Tne sniela Dell is positioned over the contaminated cask. The shielo doors on tne bottom of the shield are opened ano the cask is drawn up into the cell. The doors are reclosed and tne cask is carried, by.the crane, to the truck which has a concrete snielo vessel for isolating the cask during tranportation to the staging facility. Monitoring of the area is carried on during these activities to assure tne safety of personnel. A new cask is positioned in the vacatea space. Shielding, process lines, and level instru-mentation are repositioned and the unit is returned to service. NOTE: The transfer bell is no longer routinely useo and will only De used if operation of the system results in radiation levels from the second cemineralizer exceeding limits for unshieloed handling. 1.3.2.4 6' x 6' casks are handleo in and out of the building without shielding. Tnis is accomplished by remote opera-tion and by establishing appropriate Darriers limiting tne approach of personnel to the handling operation. Spent resin containers are lifteo directly from within suostan-tial snielding Darriers in the Chemical Cleaning Building and deposited directly in the transfer cask located on the unnanneo truck located immealately outside the building, or loadeo unshielded on a transport truck depending on the cask's raolation levels. 1.3.3 Air Kanaling Design Requirements 1.3.3.1 A ventilation fan is provided to maintain the Daemical Cleaning duilaing at a negative pressure. 1.3.3.2 The MSA Filtration Unit is designeo to meet the require-ments of NRC Regulatory Guide 1.140. -.

~. _. t 4 1.3.3.3 The moisture separator is provided to remove water-vapor aroplets from tne air. 1.3.3.4 An electric heater is provioed within the Filtration Unit to lower relative humidity to 30% with 100% RH inlet air. 1.3.3.5 The prefilter nas an average atmospheric air strain effi-ciency of 85%. 1.3.3.6 The two HEPA filter banks are 00P tested in place to assure an efficiency of 99.97% for removirig 0.3 micron particles. 1.3.3.7 The activated charcoal filter is designed to have effi-ciencies of 99.9% for elemental iodine and 95% for methyl iocide. 7-

7-t d 2.0 DETAILED DESCRIPTION OF THE SYSTEM 2.1 Components 2.1.1 EPICOR II Pumps (ALC-P-1 through 4 and 6) Pumps (1-4) are air-driven, positive displacement pumps witn a capacity of from 10 gpm to 120 gpm. Each pump is equippeo witn a pulsation dampener in the process outlet. Pumps ALC-P-1 tnru 4 are utilized in the system to circu-late tne liquio through the prefilter and demineralizers, and Pump ALC-P-6 is used for chemical addition to the Off Spec Water Receiving Batch Tank or to supply pre-coating fluid to the prefilter elements. Tne hoses furnished for tne flexiole connections to the pumps, filters, ceminera-lizers, and traps have a design pressure of 100 psi. Air supplied to the pumps passes through an air oiler and an anti-freeze injector to a valve manifold. Pump speed ano capacity will oe varieo by the EP100R II operator to achieve the optimum flow through tne radwaste process system. Pump speed is controlleo by tnrottling the orive air at the Fava Control Panel. Demineralized water and oil free air connections are provideo on the suction and discharge side of each pump for flushing and Olowdown purposes. Refer to Tacle 1 for pump details. Pump noise and vioration monitors are present for pumps ALC-P-1 thru 4 and have a read-out on panel ALC-PNL-2 in the TV Monitor & Control Building. 2.1.2 Transfer Pump ALC-P-5 Tne transfer pump (lable 2) is a single stage horizontal centrifugal pump witn a capacity of 200 GPM at 90' head. Tne pump motor is rated at 10 HP and is powered from MCC 2-33A in the TV Monitor & Control Building. The pump is controlleo oy pusn cuttons for START /STOP from MCC 2-33A, a hano selector switen for low level control of tank CC-T-1 or CC-T-2 from the panel ALC-PNL-1 in the TV Monitor Control dailding and level switches in panel ALC-PNL-1 for tanks CC-T-1 and CC-T-2. Ihe level switches receive their signals from level transmitters ALC-LT-1 and ALC-LT-2 at tanks CC-T-1 and CC-1-2, respectively. CC-T-l&2 also have high level cutouts to ALC-P-5. Demineralized water is supplied to the pump mechanical seal from a solenoid operated valve, ALC-V136, controlled from the pump motor starting circuit. The valve opens, when the motor is started, by energizing the solencio. The seal water flow rate is maintained at 1-2 GPM by throttling ALC-V134 when seal water injection is requireo.

J - ~ ~ - t Seal water injection is only required if the pump is handling water which contains grit which could damage the mechanical seal. If the pump handles clean water, it is acceptable to allow the mechanical seal to be lubricated through tne pump's internal passages. As long as the water, wnich pump ALC-P-5 handles, has passed through the one micron filter (ALC-F-5), the water is clean enough (from a grit stanapoint) to lubricate the mechanical seal. Thus, as long as filter ALC-F-5 is in use, the demineraliz-ed seal water can be turned off with valve ALC-V134 to reduce the total volume of processed water or radwaste. Tne pump is used to transfer water from the Clean Water Receiving Tank to the TMI Unit 2 Liquid Waste Disposal System, tne Spent Fuel Storage Pool, the PWST's, a hose connection at tne truck fill station, or to the Off Spec Water Receiving Baten Tank tot recycling through the cleanup system. Tne pump may also be used for recirculating and sampling the contents of the Clean Water Receiving Tank and the Of f Spec water Receiving Batch Tank. Tne sample connection terminates at the Sample System sink. The pump is provided witn a disenarge pressure gage, and a flow element on the discharge line to Units No. 1, No. 2, the Spent Fuel Pool, tne PWST 's and the truck fill station. Remote indication of flow (ALC-FI-2) ano a flow totalizer (ALC-FQ-2) are located on Panel ALC-PNL-1. 2.1.3 Prefilter (ALC-F-1) Tne pref 11 tar (Taole 3) is the first stage of the Auxiliary Building Bnergency Liquid Clean-up system. The filter is used to remove sodium and other non-radioactive chemicals. If the system is oeing useo as a polisning system for the SOS effluent, tne prefilter may be replaced with a demin-eralizer liner, if it has oeen determined that it is not requireo. Tne pref 11ter unit is a caroon steel tank approximately 6 feet in diameter ano 6 feet hign. The top of the tank has four quick disconnect type male fittings; an inlet (pump disenarge), an outlet (pump suction), a threaded level proce connection, air Duboler level connection, ano a comoination vent / overflow connection. A 1/4" air connection is provided at the top of the liner to allow removal of the plug from tne top of the false cottom after final dewatering. The false bottom is filled _9_

t witn vermiculite to absoro water that may tend to accumulate to meet snallow land burial requirements. A manway approximately 24" in alameter is installed on top of the tank. On tne manway cover is a four inch inspection port usea for resin sampling once the container is spent. The inlet nipple is connected to a full dispersion manifola in the top of tne tank. The outlet nipple (pump suction line) connects to a single layer cotton wound tubular filter manifola whian is located at the Dottom of the tank. The level probe maintains tank level oetween 4" and 6" from the top of the resin oy opening and closing solenoid valve (ALC-V185) on tne air supply to pump ALC-P-1, which is supplying tne tank, starting the pump on low level, and stopping the pump and closing valves ALC-V043 or ALC-V242 on high level. On Hi Hi level 4" from the tank top, an audible alarm is sounded at the EPICOR Monitoring Console, locatea in the TV Monitor & Control Building, ALC-V255 closes, pump motor operated valve closes. Tne EPICOR 11 operator may select either air Ducoler or conductivity level control on the Fava Control Panel located in the TV Monitor and Control Builaing. Tne prefilter tank is vented, via hose connections, to a 2" vent neader wnicn leads into the top of the Off Spec Water Receiving datch Tank (CC-T-1). A tee is provioeo in this vent line for a hose connection to a common header wnich discharges ~to the CC8 sump. The line is provioeo_as a prefilter overflow line and prefilter overpressure protection. A loop seal is providea to ensure tnat all cask gases are routea to tank CC-T-1 and its M ot filters, rather tnan directly into the Chemical Cleaning i l Building. A level switen (ALC-LS-21) is installed in the i loop seal for indication of flow in the heaoer and provides an alarm at panel ALC-PNL-1 in the TV Monitor & Control Building. The snielaing in the prefilter position consists of a. 5 1/8" thick, square lead orick wall (3 1/8" thick on south I sloe) plus a 1/2" of shield-supporting steel. Radiation monitors (ALC-RM-1 ano 2) are located inside this shield 180 degrees apart at different elevations to monitor accumulateo radiation levels in the prefilter. To avoid creakthrough of soaium to the second liner, the batch size through the prefilter is limitea. -

? O ~ Remote 1ncication is provided on tne Cleanup Panel ALC-PNL-1 for ALC-RM-1 and 2. During system operation, raciation levels as inoicatea on ALC-RM-1 and 2 shou ce alloweo to exceed 1 R/HR. 2.1.4 Demineralizer (ALC-K-1, ALC-K-2) Two demineralizers (Table 4) are installea in series w the prefilter to further remove racioactivity from the waste liquid and polish the effluent. The first demineralizer (ALC-K-1) a 6' x 6' liner, is primarily useo to reduce the activity level of the process fluio througn ion exchange ano filtering. For this reason, tne anticipated activity levels are high and the snielding around ALC-K-1 is identical to shielding around the prefilter. Demineralizer (ALC-K-2) a 4' x 4' liner is primarily used to polish the effluent water from ALC-K-1 and act as e guard in tne event of a resin breakthrough from ALC-K-1. For this reason, the anticipated activity levels in ALC-K-2 are lower than ALC-K-1. Eacn cemineralizer has the same external connections prefilter. As with the prefilter, a 1/4" air connection is provicea at the top of tne liner to allow removal of the plug from the top of the false 00ttom after final dewater-ing. The false bottom is filled with vermiculite to absorb water that may tend to accumulate to meet shallow land ourial requirements. suction line) extenas to the bottom of the tank.The oeminera Filter elements on the eno of the line keep resin inside of the demineralizer. Tne cemineralizer resin composition and quantity will De ceterminea on the basis of system samples ano operating cata. As with the prefilter, two radiation detectors are locateo at different elevations 180 cegrees apart inside the lead shield. Remote indication is provideo in the TV Monitor & Control Building on Panel ALC-PNL-1. ( During system opera-tion, radiation levels as indicated on ALC-RMI-3 ano 4 for ALC-K-1, snould not De allowed to exceed 1 R/HR. Radiation levels as indicated on ALC-RMI-5 and 6 for ALC-K-2, shoula not ce allowea to exceed 1R/HR. 2.1.5 Miscellaneous Waste Hold-up Tank (WDL-T-2) The Miscellaneous Waste Hold-up Tank (Table 5) which has a capacity of 19,518 gallons, can receive liquid from the following sources: -

The tank is normally nitrogen Olanketeo, but may be vented to the WDG System. To prevent acio splashing on the inner tank walls, the inlet piping extends into the tank 8 ft. The diameter of the tank-is 10'-9-1/4". The Miscellaneous Waste Hold-up Tank is located in the Auxiliary Bulloing elevation.305'. A temporo'ry tee connection is installed in place of the suction line strainer, WDL-U2028, on the Miscellaneous Waste Tank Pump WDL-P-68 suction line. Connected to this tee is a 2" line which supplies the liquid from the Miscel-laneous waste Holoup Tank to the suction side of EPICOR II Pump ALC-P-1. A 4" guard pipe with a combination of leaa and concrete shielding encloses tne suction piping run from tne Auxiliary duiloing corridor to the Cnemical Cleaning Building penetration. The guaro pipe is open to the atmosphere of the Cnemical Cleaning Building, which is unoer a slight negative pressure.

. - -. ~ -. t 1 2.1.6 Clean Water Receiving Tank (CC-T-2) The Clean Water Receiving Tank (Table 6) is a stainless steel atmospheric pressure tank with a capacity of 133,700 gallons located in the Chemical Cleaning Bulloing. Tne tank receives the processed liquid from the discharge of pump ALC-P-4 via, in oroer, three resin traps, a one-micron cruo filter, radiation monitor, conductivity cell, pH meter, and an inlet flowmeter / totalizer. An overflow line with a loop seal is provioed near the top of the tank. A cemineralized water supply is provided for the loop seal. A suction line from the transfer punp (ALC-P-5) penetrates the tank skirt and Connects to the cottom of the tank.- A connection is also provided for the transfer pump recirculation line.

Tnis would include preoperational testing or tank cleanup. A orain line is provideo off the Transfer Pump (ALC-P-5) suction piping to drain tne suction piping and the remaining water in tne tank tnat the transfer pump-Cannot drain. The tank has a 2" vent line exhausting to the Cnemical Cleaning Builaing through a two-stage demister filter. -The first stage consists of two moisture separators and an HEPA filter. The second stage consists of two charcoal filters and an HEPA filter. A neater in the common 2" vent line is I controlleo from Power Panel W-2-33A. Tne heater is normally energized. Processed water is stored in the tank until a catch is completed. A representative sample of the processed water can De ootained from the discharge of the transfer pump at the sample sink after recirculating three volumes of the l tank and purging the sample lines for five line volumes i Defore drawing the sample. If the sample indicates the water is unsatisfactory for disposal, the water can De pumped to the Off-Spec Water Receiving Batch Tank for temporary storage or routed directly back into the suction line of pump ALC-P-1 for reprocessing through the filter ano cemineralizers until the quality is acceptaoie for discharge to the environment. If sampling indicates that the tank's contents are satisfactory for oisposal, the water is pumped normally into the TM1 Unit 2 Liquid Waste l Disposal System, the Spent Fuel Storage Pool, the PWST's or to a tank truck at the truck fill station, nowever, it may l.

The Off-Spec Water Receiving Batch Tank should be flushed clean with cemineralized water before it is used for clean water storage. 2.1.7 Off-Spec Water Receiving Baten Tank (CC-T-1) Ine Off-Spec Water Receiving Baten Tank (Table 7) is a stainless steel tank With a Capacity of approximately 86,000 gallons designed for full vacuum to 75 psig. For the Auxiliary Building Clean-up System, the tank will be operated at atmospheric pressure only. Tne tang can receive the discharge from the Clean Water Receiving Tank Transfer Pump whenever it is desired to either recycle the water for further processing, or store the purified water for future disposition. This feature allows greater availability of the Clean hater Receiving Tank. The Tank is pipeo up to receive the discharge from the sump pump, if aesired, out normally the sump is crained by a 2" suction line to the Pump ALC-P-1 (see para. 2.1.8). A suction line at the cottom of the tank can be lined up eitner to Pump ALC-P-1 for reprocessing the tank's contents tnrougn-tne cystem or to the Transfer Pump ALC-P-5 for recirculation ano sampling, or discharge. Tne tank is ventea to the ouiloing in the same manner as tne Clean Water Receiving Tank. An over-flow line witn a loopseal is proviceo near the top of the tank. A demin-eralizea water supply is provided for the loop seal. A connection at the top of the tank receives vents from the prefilter, the demineralizers and the cruj filter. Cnem-icals for iodine fixing or pH aojustment may be adoed to the tank oy pumping through Pump ALC-P-6 to a connection near tne top of the tank. Level indication and high level alarm are proviced on panel ACL-PNL-1. A future xenon holo-up tank connection is provioed on the vent line.

Ensure that the radiation monitor is energized and operational. When the fan is started (at MCC2-33A) ensure sufficient air flow exists (approx. 4000 CFM minimum) through the unit before energizing the heaters (Note: Heaters should not energize if insufficient air flow exists). After startup, verify that ventilation unit temperature, flow and activity i indications are normal.before-leaving unit unattended. NOTE: Start push button will have to be depressed and held until flow increases above lower limit or fan will trip. 3.1.2 Cleanup System . Initial startup of the Auxiliary Building Emergency Cleanup System will be with the Prefilter and Demineralizers empty of liquid. The Chemical Cleanup Building Ventilation System shall be in operation prior to operating the cleanup system.. Before contaminated liquid flow is initiated the line between the source tank and ALC-V043, or the line back to CC-T-1 through valve ALC-V242 is primed with demineralized water. Motor operated valve ALC-V043 or solenoid valve ~ ALC-V242 is then opened and Epicor II pump ALC-P-1 is started by opening the air motor air supply valve (ALC-V185). Liquid waste is pumped from the source tank to the Prefilter, ALC-F-1,-until the prefilter tank is full and the pump stops on high tank level. Epicar II Pump ALC-P-2 is similarly operated until Demineralizer ALC-K-1 is full and ALC-P-3 is operated until Demineralizer ALC-K-2 l 1s full. The air supply valves ALC-V0ll, V028, V025 & V022 l-for Epicer II pumps ALC-P-l thru 4 respectively are i throttled to maintain a balanced flow of about 10 gpm through the prefilter and demineralizers. NOTE: The initial batch quantity will be determined by the efficiency of the demineralizer resin charge and may require a change in resin composition and/or flow rate to effectively process the radioactive waste water..-

t 3.1.3 SOS Polishing Startup 4 Prior to startup for the SOS Polishing Mode, the 4 x 4 liner and top shielding for ALC-K-1 will have.to be removed ana replaced with a 6 x 6 liner.

All other Startup procedures.are the same as those iden-tified in Section 3.1.2. 3.2 Normal Operation 3.z.1 Ventilation System Ouring normal operation, tne ventilation unit should require little operator action. The unit should be pericalcally checked to ensure that inoication is operable and that temperatures, flows and radiation levels are within the normal ranges. Increasing alfferential pressures across the moisture separator and HEPA filters are an indication that the components are retaining dirt, etc. These components should be replaced as required to ensure that flow through the ventilation unit is maximized. The radiation monitor and recorder should De checked - periodically and reviewed for eviaence of trends indicating that increasing levels of activity are being discharged. A trend snowing increasing discharge activity levels can be indicative of carryover from the filter unit and should be treated accordingly. 3.2.2 Cleanup System Once the flow rate is estaolished for the process, the system operates automatically by starting and stopping the pumps ( ALC-P-1, z, 3 and 4) in order to maintain the proper level in the process tanks. Instrumentation is provided on tne control panel to monitor system parameters ano to calance the system to minimize pump cycling. Upon completion of processing one batch, Transfer Pump ALC-P-5 is started to recirculate at least thIee tank volumes of water through the Clean Water Receiving Tank after which a sample is drawn for analysis Oy the TMI water enemistry laooratory.
