Provisions are made to preclude uncontrolled radioactive releases by providing a stop valve interlocked with a radiation monitor on the system discharge line. The valve automatically closes when the waste activity reaches the monitor set point. As an additional precaution, the stop valve is also interlocked with the circulating water pump controls to block flow if sufficient dilution water is not available.

11.2.2 SYSTEM DESCRIPTIONS 11.2.2.1 General The LWPS collects and processes potentially radioactive wastes for recycle or disposal during the normal mode of operation. Should 46 administrative releases be necessary, provisions are made to sample and at.alyze fluids before they are discharged. Based on this analysis, these wastes are either released under controlled conditions via the circulating water discharge canal or retained for further processing. If an administrative release is necessary, the circulating waterflow serves to reduce the concentration of radioactivity in the plant effluent by diluting the LWPS discharges. A permanent record of I

radioactivity releases is provided by analyses of known volumes of affluent.

The bulk of the radioactive liquids discharged from the RCS are processed by the Boron Recycle System (BRS). This processing limits input to the LWPS and results in a processing of relatively small I

quantities of generally low-activity-level wastes.

t Enclosura to TXX-89547-CPSES/FSAR August' 31, 1989 Page 4 of 63 Based on operating plant data, the volume of laundry and hot shower waste is estimated to be approximately 120,000-gal per

' DRAFT.

year per unit.

Processing of contaminated plant laundry will be.

performed by an outside vendor.

DRAFT The liquid collected in the laundry and hot shower tank is pumped throuJh the laundry and hot shower tank strainer and filter to one o: the two 5000-gal waste monitor tanks. The waste water is then sampled to determine if the liquid is to be discharged or reprocessed through the filter demineralized system or the waste evaporator.

5.

Spent Resin Handling Subsystem This subsystem collects, handles, and processes spent resins frcm the primary fluid systems prior to their disposal.

46 Spent resin from the primary system demineralizers is transported to and stored in the spent resin storage tank prior to being packaged for disposal. The spent resin sluice portion of the LWPS consists of a spent resin sluice filter, spent resin sluice pump, and the spent resin storage tank. The resin sluice water, after being directed to an ion exchange vessel by the sluice pump, is returned to the spent resin storage tank for reuse.

Thus, sluicing of spent resin from primary plant demineralizers is normally accomplished without generating a large volume of DRAFT additional liquid weste.

For additional system flexibility the spent resin storage tank may be bypassed and the resin sluiced directly from a desineralizer to a Mobile System for disposal.

46 The resin slurry from the spent resin storage tank is transferred to the waste processing area by pressurizing the tank with nitrogen.

The existence of primary-to-secondary leakage in a unit is a criterion in the recycle'of the waste monitor contents to that unit's condensate storage tank, Note that water leaving Drain Channel' B for either reprocessing or secondary cycle reuse 19 is monitored for radiation. Detection of high levels'of radioactivity in the effluent stream causes the appropriate 46 control valve (RV-5252) to close and sounds an alarm. The element can be cleared by flushing it with demineralized water from the temporary connection back to the waste monitor tank. A third path for Drain Channel B occurs when water has been-sufficiently processed, but cannot be recycled.

It is discharged into the condenser cooling water at a rate determined by the dilution flow rate available.

31-The discharge pipeline to the Circulating Water System is common to both Drain Channel 8 and Channel C and uses a flowmeter with a-totalizer, a radiation monitor, and an automatic shutoff valve similar to RV-5252.

Drain Channel B is provided with interconnections-to Drain Channel C as follows:

a-Ficor drain tank III pump discharge to the reverse osmosis system inlet b.

Reverse osmosis system outlet to floor drain tank III c.

Revision:

These changes reflect TU Electric's intention that the processing of contaminated plant laundry will be per-formed by an outside vendor rather than by using the reverse osmosis system.

FSAR Change Request Number: 89-516.03 Commitment Register Number: NL-4144 Related SER Section: 11.2.1.2 SER/SSER Impact: Yes Sections 11.2.1 and 11.2.1.2 as well as Figure 11.5 of the SER should be revised to delete mention of the reverse osmosis unit since TU Electric does not intend to use the unit.

11.2-12 3

Deletes the bypass flow path for resin sluice water that takes it around the spent resin storage tank directly to the ATCOR system for disposal.

Correction:

This change reflects the fact that the ATCOR system will not be used in the processing of radioactive wastes.

FSAR Change Request Number: 89-516.04 Related SER Section: 11.2.1.2 SER/SSER Impact: Yes Section 11.2.3 of the SER and SSER 1 should be revised l

11.2 System Description and Evaluation 11.2.1 Liquid Waste Processing System The liquid wasta processing system (LWPS)'for the-Comanche Peak Station is shared between Units 1 and 2.

The system consists of the process equipment and instrumentation necessary to collect, process, monitor, and recycle or dispose of radioactive liquid wastes.

The liquid radwasta system is designed to collect and process wastes on the basis of their origin in the plant and their expected levels of radioactivity.

All liquid waste is processed on a batch basis'to permit optimum control of releases.

Before processed liquid wastes are released, they are sampled and analyzed to determine the types and amounts of radioactivity present.

On the basis of the results of the analysis, the waste is either recycled for eventual reuse in the plant, retained for further processing, or released to the environment under controlled conditions.

A radiation monitor in the discharge line will automatically terminate the discharge of liquid waste if radiation measurements exceed a predetermined level.

The liquid radioactive waste processing system consists of the tritiated and nontritiated waste subsystems and a laundry and shower subsystem.

A senematic diagram of the liquid waste processing system is given in Figure 11.1.

The LWPS consists of three subsystems,:

the tritiated waste subsystem, the nontritiated waste subsystem and the laundry and hot shower drain subsystem.

Each reactor unit also has a, steam generator blowdown system and a condensate cleanu.o system.

Tritiated Waste Subsystem Tritiated wastes are processed through the tritiated waste subsystem and recyc' to the CVCS for reuse through a 5000 gal'wasta evaporator condensate (recycle monitor) tank.

The tritiated wasta subsystem consists of a 10,000 gal waste.

Tritiated wastes from valve and pump leakoffs, equipment drains, and plant samples are collected in the wasta holdup tank at an input flow rate of approxi-mately 300- pd per reactor.

This waste is processed through an evaporator and a polis 11ng domineralizer, and after sampling and analysis, the itquid collected in the waste evaporator condensate tank will normally be recycled to the primary coolant system for reuse.

The decontamination factors listed in Table 11.3 were applied for radienuclide removal in the tritiated waste subsystem.

Spent Resin Handling Subsystem This subsystes collects, handles, and processes spent resins from t,he primary fluid systems prior to their disposal.

46 Spent resin from the primary systes domineralizers is transported to and stored in the spent resin storage tank prior to being packaged for disposal. The spent resin sluice portion of the LWP5 consists of a spent resin sluice filter, spent resin slutce pump, and the spent resin storage tank. The resin slutce water, after being directed to an ton exchange vessel by the slutce pump, is returned to the spent resin storage tank for reuse.

Thus, sluicing of spent resin from primary plant deafneralizers is normally accomplished without generating a large volume of 66 additional liquid waste.

The existence of primary-to-secondary leakage in a unit is a criterion in the recycle of the waste monitor contents to that unit's condensate storage tank. Note that water leaving Drain Channel B for. either reprocessing or secondary cycle reuse 31 is monitored for radiation.

Detection of high levels of radioactivity in the effluent stream causes the appropriate 46 centrol valve.(RV-5252) to close and sounds an alarm. The element can be cleared by flushing it with demineralized wcter from the temporary connection back to the waste monitor tank.

A-third path for Drain Channel B occurs when water has been sufficiently processed, but cannot be recycled.

It is discharged into the condenser cooling water at a rate determined by the dilution flow rate available.

31 The discharge pipeline to the Circulating Water System is common to both Drain Channel B and Channel C and uses a flowmeter with a tota 11zer, a radiation monitor, and an automatic shutoff valve similar to RV-5252.

Drain Channel B is provided with interconnections to Drain Channel C as follows:
