ontaining the entire expected inventory of one or more tanks in the event of spills, leaks, and component failures. 14. 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 dilution flow rates and features to terminate releases or isolating process flows when deviations exceed preset limits. 15. Special design features, topical reports incorporated by reference, and data obtained from previous experience with similar systems as described in the SAR or other supporting documents (e.g., the design basis documentation from other operating plants). 16. For multi-unit reactor stations, descriptions and design features of equipment and components (included in permanently installed systems or in combination with mobile processing equipment) normally shared between interconnected processing and treatment subsystems. 17. Types and characteristics of filtration, ion-exchange resins, and adsorbent media to treat liquid process and effluent streams, including expected removal efficiencies, decontamination factors, 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. 18. Design features and operational safeguards to prevent the introduction and mixing of chemical additives with ion-exchange resins in avoiding the generation of exothermic reactions and explosive gas mixtures (e.g., hydrogen and methane) in LWMS and solid
