Content:
. Before its use, all flexible piping should be hydrostatically tested to at least 1.5 times the interfacing system design pressure and maintained for at least 30 minutes without leakage or structural deformation to ensure the integrity of the flexible piping and associated fittings. C. Corrosion-resistant properties should be used for all system piping and valves associated with transfer lines to storage tanks and discharge piping, including features designed for the early detection of leaks and spills. D. Portable systems should be located, as a minimum, on concrete pads with curbs and drainage provisions to process drains and drip pans or containment boxes to contain radioactive leaks. Provisions should be available for interfacing system drains with the plant’s liquid radwaste system. Other safety features may include backflow preventers, siphon breakers, self-sealing quick-disconnects, and operational interlocks to prevent spills. Portable systems should have integral ventilation systems with self-contained filters or interface with the plant’s ventilation exhaust system. E. Mobile liquid waste processing systems with interconnections to permanently installed plant liquid waste management subsystems should include provisions that (1) avoid the contamination of nonradioactive systems, (2) prevent uncontrolled and unmonitored releases of radioactive materials in the environment, and (3) avoid interconnections with potable and sanitary water systems. F. Designs should minimize the potential for spills and leaks to the extent practicable, consistent with maintaining radiation doses ALARA during operations and for the purpose of facilitating decommissioning. G. Regulatory Guide 1.143 seismic criteria for structures housing portable solid waste systems are not applicable. 5. Additional Design Features The following additional features should be incorporated into the design of the solid waste system. A. Process concentrate piping and tanks should have heat tracing
