Content:
the conduct of fire hazards analyses in minimizing the potential for radioactive releases in plant areas and to the environment in the event of a fire involving radioactive materials. 5. Addition of a discussion on 10 CFR Part 50, Appendix A, GDC 2, as it relates to the design bases of structures housing SWMS and its components using the guidance in RG 1.143 in assigning seismic and quality group classifications, and safety classifications for natural phenomena and man-induced hazards as defined in RG 1.143 in assigning safety classifications to SWMS SSCs for design purposes. 6. Addition of a discussion on 10 CFR Part 50, Appendix A, GDC 3, as it relates to the design of SWMS systems and operational safeguards to avoid the generation of explosive gas mixtures and exothermic reactions through the inadvertent introduction and mixing of chemical agents with adsorption media using the guidance in RGs 1.189 and 1.205 in conducting fire hazards analyses involving the presence of radioactivity in combustible or flammable materials. Using GDC 3 provides reasonable assurance that radioactive materials are protected from the effects of fires and that the function of its plant systems and components will not be compromised in meeting effluent discharge concentration limits of 10 CFR Part 20 associated with releases of contaminated fire protection water and combustion gases and smoke. 11.4-65 Revision 4 – January 2016 7. Addition of a discussion on 10 CFR Part 50, Appendix B, QA Criteria for Nuclear Power Plants and Fuel Reprocessing Plants, insofar as it applies to SWMS systems and components not covered by the QA guidance of RG 1.143. 8. Addition of a discussion on 40 CFR Part 190 (EPA generally applicable environmental radiation standards), as implemented under 10 CFR 20.1301(e), as it relates to limits on annual doses from all sources of radioactivity released via effluent discharges and external radiation from site buildings and facilities (with single or multiple
