American National Standard: for gaseous radioactive-waste-processing systems for light-water-reactor plants

This standard sets forth minimum design, construction and performance requirements, with due consideration for operation, for Gaseous Radioactive Waste Processing Systems for light water reactor plants. It is applicable for routine operation including design basis fuel leakage and other design basis occurrences. For the purpose of this standard, the Boiling Water Reactor (BWR) Gaseous Radioactive Waste Processing Systems begin at the point of discharge from the main condenser air removal equipment, the main condenser mechanical vacuum pump and the turbine steam packing exhauster. For Pressurized Water Reactors (PWRs), the Gaseous Radioactive Waste Processing Systems begin at the point of discharge from plant components, systems and equipment designed for the removal of radioactive gas from the reactor coolant system. The standard also addresses the release of radioactive materials in gaseous discharges from other plant systems. The systems terminate at the point of introduction into the plant ventilation exhaust stream(s). The Gaseous Radioactive Waste Processing Systems are not safety systems nor do they contain components that are safety class
