THREE MILE ISLAND NUCLEAR STATION 2/8/74 HEALTH PHYSICS PROCEDURE 1629 Liquid Uaste Disposal System Sampling 1.0 FURPOSE This procedure describes the samples that must be taken of various radioactive liquids prior to utilizing the liquid in another opera-tion or prior to transferring the liquid to other components of the liquid waste disposal system (pertinent to OP llc 4-29-A through Y).
2.0 DISCUSSION The liquid waste disposal system has been engineered to maintain radioactivity levels in liquids at or below designated values.
The major components of the system are tanks, pumps, pre-coat filters, demineralizers, evaporators, coolers, and ficor and equipment drains with associated sumps.
The liquid waste disposal system provides oper-ating service functions to the primary system and spent fuel pools in addition to the collect on, containment and processing of miscellan-ecus wastes for re-use or disposal. The functions are as follows :
2.1 Operating service functions to primary system and spent fuel pools.
2.1.1 Chemical shim and volume control for primary system.
2.1.2 Pressurizer relief suppression, containment and collection.
2.1.3 Drain and fill primary system.
2.1.4 Clean-up spent fuel pool water.
2.1.5 Process primary coolant and refueling water for re-use er f
4 disposal.
2.1.6 Process spent fuel pool water for re-use er disposal.

'2.2 Miscellaneous Tunctions of the LWDS:
2.2.1 Process miscellaneous wastes from:
2.2.1.1 Radioactive laberatory drains, 2.2.1.2 Building and equipment drains, 2.2.1.3 Regeneration of deborating resins,
2.2.1.4 Discharge of spent resins from demineralizers,
2.2.1.5 Discharge of used pree r o from preccat filters, 2.2.2 Process radioactive laundry and shower drain waste for disposal.
2.2.3 Safely dispose waste liquids from both functions to the river.
2.3 The amount of a adicactivity in the liquid is dependent on the use of that liquid at the nuclear station.
Primary coolant is expected to have higher radioactivity levels than water used in the laundry of contaminated clothes.
It follows that speci-fications as to the acceptable level of radicactivity in liquids to be used for one purpose will differ considerably from those used for another purpose.
In crder to verify the radioactivity level in a liquid, samples are take and analyzed for gross beta-gamma activity.
The liquids are then treated by filtration, -
demineralization and/cr evaporation, as required.
2.4 Liquid waste disposal system piping is so arranged that all liquids collected in equipment of either *ae primary coolant or miscellaneous waste chains must be routed through the reactor coolant or miscellaneous waste evaporators and the con-densate demineralizers and be collected in the waste evacorator
~
condensate storage tanks before they can be discharged to the mechanical draft cooling tcwers.
