Content:
s 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 materials into the environment, and (iii) avoid interconnections with potable and sanitary water systems. E. Pressure testing of all temporary and flexible lines, system piping embedded in concrete, and effluent discharge lines or piping buried in soils should be done. See guidance provided in RG 1.143 for liquids and liquid wastes produced during normal operation and AOOs. F. Corrosion resistant properties all system piping and valves associated with transfer lines to storage tanks and discharge piping in soils and concrete should be included, including features designed for the early detection of leaks and spills (e.g., leak detection sumps and wells). 3. Acceptance Criterion II.3 gives the technical rationale for the 10 CFR 50.34a requirement. Meeting the requirement of 10 CFR 50.34a, as it relates to the LWMS, provides assurance that each nuclear power reactor will have the necessary design features and equipment to control releases of radioactive liquid effluents to the environment in accordance with the requirements of 10 CFR 20.1301 and 20.1302, Appendix I to 10 CFR Part 50, and GDC 60 and 61. 4. Appendix I to 10 CFR Part 50 provides numerical guidance on design objectives to meet the requirements that radiation doses caused by radioactive materials in effluents released to unrestricted areas be kept ALARA. Sections II.A and II.D of Appendix I relate to the numerical guides for dose design objectives, limiting conditions for operation, and 11.2-10 Revision 4 - May 2010 controls to meet the ALARA criterion for liquid effluents. RGs 1.109 and 1.113 provide acceptable methods for performing dose analyses to demonstrate that the LWMS design results in doses caused by releases of radioactive materials from each reactor comply with Appendix I dose objectives.
