ices for achieving functional goals, or (2) requirements derived from analysis (based on calculations, experiments, or both) of the effects of a postulated event or accident for which an SSC must meet its functional goals. Each operating plant falls into one of three groups: (1) plants with operating licenses issued before January 1, 1979, and a deterministic FPP (also known as “pre-79” or “Appendix R” plants); (2) plants with operating licenses issued after January 1, 1979, and a deterministic FPP (also known as DG-1359, Page 10 “post-79” or “BTP” plants); and (3) plants that have adopted a risk-informed, performance-based FPP through 10 CFR 50.48(c) (also known as “NFPA 805” plants). Plants Licensed before January 1, 1979 Plants licensed before January 1, 1979, are subject to the requirements of 10 CFR 50.48(a) and 10 CFR 50.48(b). The FPP-related licensing basis for these plants comprises the plant license conditions, Appendix R to 10 CFR Part 50, approved exemptions, and the staff’s SERs on the FPP. Plants Licensed after January 1, 1979 Plants licensed after January 1, 1979, are subject to the requirements of 10 CFR 50.48(a). The FPP-related licensing basis for these plants comprises the plant license conditions, approved license amendments, and the staff’s SERs on the FPP. Plants that have Adopted 10 CFR 50.48(c) Plants that have adopted a performance-based FPP in accordance with 10 CFR 50.48(c) must meet both 10 CFR 50.48(a) and 10 CFR 50.48(c). See RG 1.205 for more information. Safety Evaluation Reports The fire protection initial licensing SERs document the staff acceptance of the plant FPP or its elements. For plants licensed to operate before January 1, 1979, the staff’s SERs also establish the extent to which the requirements of Appendix R to 10 CFR Part 50 apply. Plants for which the NRC accepted the fire protection features as satisfying the provisions of Appendix A to BTP APCSB 9.5-1, or were accepted in comprehensive SERs
