d RG 1.52, “Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Post-Accident Engineered-Safety-Feature Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants”; RG 1.140, “Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Normal Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants”; and RG 1.143. 10. Design features describing automatic control features and justification for the placement of isolation valves and radiation detectors on process piping and effluent discharge lines to ensure the timely closure of such valves upon the detection of elevated radioactivity levels. If part of the design, description of controls in monitoring deviations of in-plant exhaust flow rates and features to terminate releases or isolating process flows when deviations exceed preset limits. 11. Design features to preclude the possibility of internal explosions or detonations if the potential for hydrogen and oxygen explosive mixtures exists in system components. 12. For stations with multiple reactor units, descriptions and design features of equipment and components (either as permanently installed systems or in combination with mobile processing equipment) normally shared between interconnected processing and treatment systems. 13. Types and characteristics of filtration and adsorbent media to treat gaseous process and effluent streams, including expected removal efficiencies, decontamination factors, and holdup or decay times and the applications of these characteristics in estimating releases by specific waste streams and treatment methods. The information describing the types of proposed filtration and adsorption media should include details from the applicant or suppliers, as generic or plant-specific information, in characterizing removal efficiencies, decontamination factors, and holdup or decay times. 14. Definition of the boundary of the GWMS, beginning at the interface
