TRATION AND ADSORPTION UNITS OF NORMAL ATMOSPHERE CLEANUP SYSTEMS IN LIGHT-WATER-COOLED NUCLEAR POWER PLANTS A. INTRODUCTION This guide describes a method that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable to implement regulatory requirements with regard to the design, inspection, and testing of normal atmosphere cleanup systems for controlling releases of airborne radioactive materials to the environment during normal operations, including anticipated operational occurrences. This guide applies to all types of nuclear power plants that use water as the primary means of cooling. Title 10, of the Code of Federal Regulations, Part 50, “Domestic Licensing of Production and Utilization Facilities” (10 CFR Part 50) (Ref. 1), Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criterion (GDC) 60, “Control of Releases of Radioactive Materials to the Environment,” requires, in part, that a facility’s design include the means to control the release of radioactive materials in gaseous effluents. GDC 61, “Fuel Storage and Handling and Radioactivity Control,” requires, in part, that fuel storage and handling, radioactive waste, and other systems which may contain radioactivity be designed with appropriate containment, confinement, and filtering systems. In addition, 10 CFR 50.34a, “Design Objectives for Equipment To Control Releases of Radioactive Material in Effluents—Nuclear Power Reactors,” and 10 CFR 50.36a, “Technical Specifications on Effluents from Nuclear Power Reactors,” require, in part, that means be employed to ensure that the release of radioactive material to unrestricted areas during normal reactor operation, including during expected operational occurrences, is kept as low as reasonably achievable. 10 CFR 50.34a and 50.36a provide guidance and numerical values for design objectives to help applicants for new reactors and nuclear power plant license holders meet the
