condensation and from water-based fire suppression systems, when triggered. The design should provide the means to collect and route water to the appropriate radioactive waste management system given that the water would entrain radioactive materials present in such systems. The design of water collection systems and drains should consider the requirements of 10 CFR 20.1406 in minimizing the contamination of plant facilities and the environment. NRC guidance is presented in RG 1.143, “Design Guidance for Radioactive Waste Management Systems, Structures and Components Installed in Light-Water-Cooled Nuclear Reactor Power Plants” (Ref. 13). RG 1.143 describes systems handling of radioactive materials in liquids, gaseous and solid collection systems that include construction of structures. Further, RG 4.21, “Minimization of Contamination and Radioactive Waste Generation: Life Cycle Planning” (Ref. 14) gives guidance for Design of facilities to minimize contamination, the environment and generation of waste. NUREG-0800 “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition” (Ref. 15) and associated Interim Staff Guidance gives NRC review criteria. Nuclear Energy Institute (NEI) technical DG-1280, Page 7 report NEI 08-08A “Guidance for Life Cycle Minimization of Contamination,” (ADAMS Accession Number ML093220530, ML092720253) (Ref. 16) provides a method for licensees to describe operational policies and operational programs to meet the programmatic requirements of 10 CFR Part 20.1406(a) and (b) for life cycle minimization of contamination. Meeting these requirements is achieved pa, in part, by addressing the applicable regulatory position elements of Regulatory Guide 4.21. The main objective of the regulations and NRC guidance is to avoid unmonitored and uncontrolled releases of radioactive materials on the site and in uncontrolled areas, and provide information that can be used to assess potential
