Content:
al Regulations (10 CFR) section 50.48(a) and (b) (Ref. 1), and 10 CFR Part 50, Appendix R, “Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979” (Ref. 2). These regulations state the requirements governing a civilian nuclear power generating plant’s fire protection program (FPP). Applicability This RG applies to reactor licensees or applicants subject to 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities” and 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3). Since not all of the fire protection regulations promulgated by the NRC apply to all plants, licensees should refer to their plant-specific licensing bases to determine the applicability of a specific regulation to their plant. Applicable Regulations • 10 CFR Part 50 provides regulations for licensing production and utilization facilities. o 10 CFR 50.48, “Fire protection,” requires each operating nuclear power plant to have a fire protection plan that satisfies General Design Criterion (GDC) 3, “Fire protection,” in Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50. The regulation specifies the contents of a fire protection plan and lists the basic fire protection guidelines for the plan. o 10 CFR 50.48(b) states that Appendix R to 10 CFR Part 50 establishes fire protection features required to satisfy GDC 3 of Appendix A to 10 CFR Part 50 with respect to certain general issues for nuclear power plants licensed to operate before January 1, 1979. DG-1359, Page 2 o 10 CFR 50.48(b)(1) states that, with the exception of the requirements in Sections III.G, III.J, and III.O of Appendix R to 10 CFR Part 50, the provisions of Appendix R do not apply to nuclear power plants licensed to operate before January 1, 1979, to the extent that— (1) Fire protection features proposed or implemented by the licensee have been accepted by the NRC staff as satisfying
