atures to prevent, control, and collect radioactive materials from building ventilation systems and ductwork, and gases vented from SWMS components and mobile processing equipment. The discussions now also refer to RGs 1.54 and 4.21 and industry guidance under NEI 08-08A in meeting the requirements of 10 CFR 20.1406. 3. For processing systems equipped with automatic control features, justification for the placement of isolation or diversion dampers/valves and radiation detectors on process piping, ductwork, and effluent discharge lines to ensure the timely closure of valves and dampers upon the detection of elevated radioactivity levels, and, if part of the design, controls in monitoring deviations of process and discharge flow rates and terminating releases or isolating process flows when deviations exceed preset limits. 4. Design features and operational safeguards to prevent the introduction and mixing of chemical additives with adsorption media to avoid the generation of exothermic reactions and explosive gas mixtures in SWMS components. 5. With respect to the management of all expected forms of radioactive wastes, the guidance addresses inventories of radioactive wastes that will be generated infrequently, such as large components, activated components, and Greater-than-Class C wastes (e.g., neutron-activated components, in-core neutron detectors, etc., but excluding spent fuel). The guidance considers planning and the management of such wastes onsite over short and long-term storage duration if offsite storage and offsite disposal at licensed facilities are not available during the operational life of the plant. 11.4-61 Draft Revision 4 –August 2014 6. The listing of plant systems identified in review interfaces has been expanded to ensure that the staff’s review of radiological considerations is properly integrated with parallel and complementary evaluations conducted by other technical disciplines. For systems that contribute potential liquid and gaseous
