for liquid effluents, SRP Section 11.3 for gaseous effluents, and SRP Section 11.4, “Solid Waste Management System,” for wet and solid wastes generated as byproducts of the operation of the liquid waste management system (LWMS) and gaseous waste management system (GWMS). The sources of radioactivity include: A. Gaseous wastes (noble gases, radio-iodine, particulates, carbon-14, and tritium) consisting of offgases from the primary coolant, steam generator blowdown treatment system; offgases from the main condenser evacuation system and turbine gland sealing systems; leakage to containment, fuel handling, service, auxiliary, and turbine building drains; noble gases stripped from the primary coolant during normal operation and at shutdown; and cover and vent gases from tanks and equipment containing radioactive materials. The presence and concentration of radioactive materials in primary coolant is also expected to account for the type of primary coolant chemistry being proposed, such as lithium hydroxide with or without boron, and zinc and hydrogen injection, as defined by the applicant. B. Liquid wastes (dissolved or entrained noble gases, radio-iodine, particulates, carbon-14, and tritium) consisting of primary coolant processed to remove radioactive materials and, if applicable, to control boron concentration (shim bleed) leakage collected in equipment and floor drains from buildings housing equipment and components that contain radioactive process fluids; steam generator blowdown and blowdown treatment; condensate demineralizer regenerant solutions; contaminated liquids from anticipated plant operations, such as resin sluices, filter backwashes, ultrasonic resin cleaning rinses, reverse osmosis reject streams, decontamination solutions, disposition of laboratory samples and rinses; plant sampling station drains; and detergent wastes. C. Liquid wastes (dissolved or entrained noble gases, radio-iodine, particulates, carbon-14, and tritium) consisting of steam
