Content:
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 issued before the publication of Appendix A to BTP APCSB 9.5-1 in August 1976, were required to meet only the provisions of Sections III.G (III.L), III.J, and III.O of Appendix R. Pre-1979 licensees need an exemption, even if a staff decision in an SER approves an aspect of the FPP that does not comply with regulatory requirements. For example, pre-1979 licensees that have SERs, but not a corresponding exemption from the regulatory requirements (e.g., an SER that approves operator manual actions as meeting the protective requirements of Appendix R, Section III.G.2), must request an exemption under 10 CFR 50.12, “Specific exemptions,” by (1) highlighting the special circumstances of 10 CFR 50.12(a)(2), (2) citing the SER as the safety basis, and (3) confirming that the safety basis established in the SER remains valid. License Renewal The fire protection licensing and design basis under license renewal should not differ significantly from those in effect before renewal, with the exception that licensees must include fire protection SSCs in license renewal scoping and aging management programs (AMPs), as appropriate. Licensees must submit an application to renew or subsequently renew an NRC-issued nuclear power plant operating license in accordance with the provisions of 10 CFR Part 54. RG 1.188 describes an approach that is acceptable to the NRC staff for the format and content of an application. Regulatory Position 9 of this document provides guidance on the fire protection aspects of license renewal and subsequent license renewal. DG-1359, Page 11 Part 52 Licensees The FPPs for licensees that submit applications in accordance with 10 CFR Part 52 are subject to 10 CFR 50.48(a). The staff developed recommended criteria for enhanced fire protection, in accordance
