Minimum design, construction and performance requirements are established for Gaseous Radioactive Waste Processing Systems for light water reactor plants, covering both boiling water reactor (BWR) and pressurized water reactor (PWR) plants. The standard is applicable for routine operation, including design basis fuel leakage and other design basis occurrences. Sources of gaseous radioactive wastes considered for BWR plants include the main condenser air removal system, turbine steam seal system exhaust, and mechanical vacuum pump system exhaust; for PWR plants they include the vacuum control tank, reactor coolant drain tank, gas stripper, cover gases, pressurizer relief tank, air ejector exhaust, steam generator blowdown tank vent, and equipment vent header system. Sections of the standard are devoted to overall system requirements, equipment requirements, instrumentation and controls, physical arrangement, operation and maintenance and pre-operational testing and cleaning. Requirements of this standard are to take precedence over those set forth in ANSI/ANS-52.1-1978, ANS-51.1-1973(N18.2-1973) and ANS-51.8-1975(N18.2a-1975). Radioactive gaseous effluents must meet design objectives specified in Title 10, Code of Federal Regulations, Part 50, Appendix 1, and limits specified in Title 10, Code of Federal Regulations, Part 20 and Part 50, Appendix A.
