Common use of Liquid Radwaste Systems (LRS) Clause in Contracts

Liquid Radwaste Systems (LRS). The major functions of the liquid radwaste system (LRS) for each Unit are to: (a) Collect and store for processing radioactive or potentially radioactive waste fluids from the following sources external to the Liquid Radwaste System: (i) Containment radwaste sumps (ii) Radwaste building sumps (iii) Auxiliary building sumps (iv) Fuel building sumps (v) Decontamination facility (Unit One only) (vi) Radiochemistry lab (vii) Solid radwaste resin transfer/dewatering pump (viii) Condensate polishing and blowdown demineralizer regenerant wastes (ix) Turbine building sumps (x) Auxiliary steam condensate receiver tank (xi) Chemical waste neutralizer tank (xii) Boric acid concentrator (BAC) bottoms (xiii) BAC distillate. (b) Process revived wastes by filtration, absorption, ion exchange, and evaporation to obtain a maximum amount of high grade water for reuse in the reactor plant systems. This system also includes related radiation monitoring equipment. (c) Minimize the quantity of liquid wastes which must be solidified for offsite disposal. Each system consists of three holdup tanks, two holdup pumps, chemical drain tanks and pumps, ion exchange prefilters, an evaporator package, mixed bed ion exchangers and an adsorption bed, recycle monitor tanks and pump, concentrate monitor tanks and pumps, a caustic tank and batch tank, an acid tank and batch tank, an anti-foam tank and pump, Y-strainers, a desiccant breather and associated instrumentation, switches, valves and piping.
