n that SRP section as well. 2. 10 CFR 20.1406 requires that applicants describe how facility design and procedures for operation will minimize, to the extent practicable, contamination of the facility and the environment; facilitate eventual decommissioning; and minimize, to the extent practicable, the generation of radioactive waste. RG 1.143 includes guidance for SSCs outside containment that contain radioactive liquids produced during normal operation and AOOs. 11.2-9 Revision 4 - May 2010 Specific guidance to meet 10 CFR 20.1406 is listed below: A. Liquid waste processing systems (as permanently installed systems or in combination with mobile equipment) with a potential for leakage should provide means to control and contain this leakage to prevent contamination of building floors and interconnected systems (e.g., curbing, floor sloping to local drains, floor-to-floor seals over floor expansion joints, wall-to-floor joint seals, sheathed hoses, drip pans or containment boxes, backflow preventers, siphon breakers, self-sealing quick-disconnects, and operational interlocks). See guidance given in SRP Section 9.2.4, IE Bulletin No. 80-10, and IE Circulars 81-09, 77-10, 77-14, 79-07, 79-09, and 79-21. B. In facilitating decommissioning, designs should minimize embedding contaminated piping in concrete, to the extent practicable, consistent with maintaining radiation doses ALARA during operations and decommissioning. C. In minimizing the generation of waste, provisions should be provided to clean contaminated materials (e.g., system components, equipment) and regenerate or reuse resin beds as applicable (e.g., spent condensate demineralizer resin beds with some remaining ion exchange capacity when feasible). D. Mobile liquid waste processing systems with interconnections to permanently installed plant LWMS subsystems should include provisions that (i) avoid the contamination of nonradioactive systems, (ii) prevent uncontrolled and unmonitored releases of radioactive
