• Permit No. MO-0098001 FACILITY DESCRIPTION (continued)

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.

Boric acid is used as a neutron absorber/moderator 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-!-.

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

The Secondary Liquid Waste system is used to process condensate and steam generator blowdown demineralizer regeneration wastes and potentially radioactive liquid waste collected from the turbine building.

The condensate demineralizer 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 recycled back to the main condenser for reuse in the secondary cycle.

Provisions also exist to discharge the treated blowdown via #001.

The following wastewater treatment systems are used as required to treat this wastestream for recycle or discharge in compliance with NRC 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 Absorption 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" radioactive discharge criteria are met.

Outfall #002 -

Cooling Tower Blowdown Daily average flow is 4.84 MGD.

Daily maximum flow is 14.4 MGD.

This outfall consists of water from the Circulating Water System, the Service Water System, and the Essential Service Water (ESW) System. Blowdown from the cooling tower is necessary to maintain the dissolved solids concentration in the recirculating water system within acceptable operating limits.

The ESW System is not routinely used, however water from the ESW System does mix with the other systems as it is periodically run to demonstrate operability. Additionally, the ESW System can be used to maintain proper freeboard in the ultimate heat sink pond (see Outfall #017 description) by transferring water to the Service Water System.

Outfall #003 - Water Treatment Plant Wastes Daily average flow is 0.421 MGD.

Daily maximum flow is 1.645 MGD.

(These flows represent wastewater discharged to the settling basin, actual discharge will vary depending on recycle.)Outfall #003 consists supernatant from a wastewater treatment lagoon that treats wastewater to remove solids. The wastewater that is treated in the lagoon is mainly from the blowdown of accumulated river solids in the water treatment plant clarifiers.

The sand and carbon filter backwash, oil water separator and demineralizer system wastewater is also routed to this treatment lagoon. The oil water separator flow consists of wastewater from some plant sumps as well as flow from an oil recovery well that is being used to remediate a historic on-site release.

Outfall #003 is normally recycled by routing it back to the head of the water treatment plant.

Page 3 of 16 Permit No. MO-0098001 FACILITY DESCRIPTION (continue&

Outfall #004 -

Demineralizer System Wastes This discharge is now included under Outfall #003.

Outfall #007 -

3 Cell Flow Through Lagoon Daily average flow is 0.027 MGD.

Maximum flow is 0.040 MGD.

Design Population Equivalent is 400.

This outfall consists of a 3-cell lagoon designed to receive only sanitary and on-site cafeteria waste from the plant.

Sludge will be stored in the lagoon. The effluent will then be discharged to a constructed wetland.

The monitoring location will be at the discharge from the wetland.

Outfall#009 -

Intake Heater Blowdown Daily average flow 0 MGD.

Daily maximum flow is 0.006 MGD.

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.

Outfalls #010 through #015 -

Storm Water Runoff Average rainfall event is 0.794 MGD.

Once in 10 year rainfall event is 41.46 MGD.

These six outfalls discharge storm water runoff from plant and associated areas after treatment in settling ponds.

"Non-process discharges that will be discharged to SWR include three intermittent sources.

Two sources are the quarterly testing of the fire protection drains and the infrequent draining of the demineralized water storage tank.

The third source is the pumping of manholes, transformer and tank containments at the plant.

Outfall #016 -

Cooling Tower Bypass Daily average flow is 3.32 MGD.

Maximum daily flow is 14.4 MGD.

• This outfall consists of clarified river water and wastewater that has been recycled through the water treatment plant.

It is used to moderate flow through the water treatment plant and to provide carrier water in the discharge line when discharging from Outfall #001.

Outfall #017 - Ultimate Heat Sink Daily average flow is 0 MGD.

The Ultimate Heat Sink is a cooling pond that can provide cooling water to various plant systems during other than normal conditions.

Outfall #017 is the overflow from the Ultimate Heat Sink to local runoff.

It is a no discharge outfall.
