the NFPA 805, Section 2.4.4, plant change evaluation. However, certain recovery actions, whether part of the pre-transition fire protection licensing basis or not, require the use of performance-based methods, as discussed in Regulatory Position 2.4. 2.3.1 Previously NRC-Approved Alternatives to NFPA 805, Chapter 3, Fundamental Fire Protection Program and Design Elements NFPA 805 states that previously approved alternatives to the fundamental FPP attributes identified in Chapter 3 take precedence over the requirements in NFPA 805, Chapter 3. The provisions of Appendix R to 10 CFR Part 50 do not apply to nuclear power plants licensed to operate before January 1, 1979, to the extent that the NRC staff accepted fire protection features in comprehensive fire protection safety evaluation reports issued before August 1976, when the NRC published Appendix A to Branch Technical Position (BTP) Auxiliary and Power Conversion Systems Branch (APCSB) 9.5-1, “Guidelines for Fire Protection for Nuclear Power Plants Docketed Prior to July 1, 1976” (Ref. 18), or they were accepted by the NRC staff as satisfying the provisions of the BTP reflected in the NRC’s fire protection safety evaluation reports issued before the effective date of February 19, 1981. The fire protection license condition for these facilities references these safety evaluation reports for the regulatory basis for a major portion of their FPPs. The documentation that demonstrates prior NRC approval of an alternative to the requirements in NFPA 805, Chapter 3, as well as approval of non-compliances with existing license regulatory requirements, includes NRC approvals of exemption or deviation requests and fire protection safety evaluation reports related to plant-specific licensing actions. Inspection reports, meeting minutes, and letters from licensees without a corresponding written NRC approval are examples of documents that do not represent NRC approval for this purpose. Existing exemptions or deviations
