. FACILITY DESCRIPTION (cont.)

This system' serves to collect, process, store, recycle and dispose of liquid radioactive

-waste generated at Callaway. Five general sub-systems can be defined as described below.

The Boron Recycle System receives reactor coolant for the purpose of recovering the boric acid for reuse in the plant. Scric acid is used as a neutron absorber /moderater in the primary loop.

The Liquid Radwaste System collects and processes _ floor and equipment drains from the containment, auxiliary building, fuel building and radwaste buildings during normal operation. ,

The Laundry and Hot Shower system collects waste generated from washing radioactively contaminated protective gear and clothing and personnel decontamination shower wastewatir.

These wastes are then transferred to the liquid Radwaste system for treatment.

The Secondary Liquid Waste system is used to process condensate domineralizer regeneration wastes and potentially radioactive liquid waste collected from the turbine building. The Econdensate domineralizer regeneration waste is divided into two wastestreams; High TDS waste from the acid and caustic rinses used when chemically regenerating spent resin-, and low TDS waste which results from the initial backflushing of unregenerated resin and the final rinsing of the regenerated resin to remove acid and caustic.

Steam Generator Blowdown is normally domineralized and recycled to the main condenser for

' reuse in the secondary cycle, provisions also exist to discharge the treated blowdown via

1. 001.

The.following wastewater treatment systems are used as required to treat this wastestream for recycle or_ discharge in ' compliance with .1000 requirements and are also-available as auxiliary or backup treatment systems to treat this discharge for compliance with NPDES permit limitations: - Evaporation and/or Mixing and/or Filtration and/or Carbon Adsorption and/or Ion Exchange and/or Neutralization and/or Reuse / Recycle of Treated Effluent. All processing in the Radwaste Treatment-System is done on a batch basis except steam generator-blowdown.

After monitoring for. radioactive _ content,._ release rates are controlled administratively to ensure the "as low as_ practicable" radicactive discharge criteria are met.

Outfall 8002 - Coolino Tower Blowdown' A cnoling tower is utilized to dissipate excess heat to the atmosphere from the Circulating and Service. Water Systems, Outfall #002 is designated as the cooling tower blowdown discharge. _ Blowdown from the cooling tower is necessary to maintain dissolved solids concentration in the recirculating water:within acceptable operating limits.

Outfall #003 - Water Treatment plant' Wastes The water-treatment plant supplies clarified river water for cooling tower makeup and various other plant systems. The suspended material-that is removed from the river water is drawn from the bottom of the clarifiers as sludge. This sludge is routed to a sedimentation lagoon for solids removal. The oil separator discharge, previously designated as Outfall #005,-is alra routed to this sedimentation lagoon. The supernatant from this cedimentation lagoon is designated as Outfall #003. Outf all #003 is normally recycled by routing it back to the head of the. water treatment plant. Filter backwash from the sand and carbon filters are also a component of this outfall.

Oatfall #004 - Dominera11cer System Wastes The domineralized water system (DWS) is used to produce the high quality makeup water required by some plant processes. A well on the plant site is used as the water source for the DWS. Outfall #004 consists of wastes generated from resin regeneration and miscellaneous, wastes'from floor drainage and wet well overflows, These waste streams are routed to a sedimentation pond prior to discharge.

-Outfrl1 #007 - Sanitarv Treatment Plant (STp)

Outfall #007 is defined as the sanitary wastewater treatment system discharge. The system consists of two 25,000 gallon aerated scrge tanks, two 20,000 gallon per day extended aeration treatment units and a 7,500 gallon sludge holding tank. The STp sludge is currently trucked to the city of Fulton treatment plant for further treatment and disposal. Design

- sludge production is 7.2 dry tons / year.

Th'is_outfall has an optional flow path s own on the flow diagram, which may be used to temporarily eliminate the discharge. During emergency conditions the sanitary treatment plant'(STP) effluent will be routed to the water treatment plant stilling basin, for recycle, using! temporary pumps-and piping. There are two potential conditons which would require the-

-- use of this option:

1) Any extended outage of the plant discharge line, as may be required for-intermittent maintenance, would require isolation of discharges into the line.

Diversion of STP effluent during these periods would allow continued processing of sanitary wastewater-and minimiae impacts due to flow fluctuations on the treatment plant.

2) In the event of an STp upsat, the effluent may also be diverted. This would allow for identification and resolution of the cause of the upset, while preventing continued; discharge of poor quality effluent.

Outfall #009 - Intake Heater Blowdown The river intake structure contains two recirculating electric heaters which are used to prevent ice formation on the intake bar screens during the winter months. Outfall #009 consists of discharges from the infrequent blowdown or drainage of these boilers.
