ion 0 does not include guidance for plants that licensed under 10 CFR 50.48(c). This guide is being revised to include guidance for plants licensed under 10 CFR 50.48(c). Background During the initial implementation of the U.S. nuclear reactor program, the broad performance objectives of Criterion 3 in Appendix A to 10 CFR Part 50 formed the basis for regulatory acceptance of fire protection programs at nuclear power plants. In 1976, after a major fire at the Browns Ferry Nuclear Power Plant, Unit 1, the NRC staff asked existing licensees to compare their fire protection programs to newly published guidance, Branch Technical Position (BTP) Auxiliary and Power Conversion Systems Branch (APCSB) 9.5-1, “Guidelines for Fire Protection for Nuclear Power Plants” (Ref. 12) and shortly thereafter modified the BTP and added Appendix A to BTP APCSB 9.5-1 (Ref. 13). A number of plants had fire protection programs approved under these guidance documents. In 1980, the NRC issued 10 CFR 50.48, which specified broad performance requirements, as well as Appendix R to 10 CFR Part 50, which contained detailed regulatory requirements for resolving the disputed issues. As issued, 10 CFR 50.48 allowed plants licensed to operate prior to January 1, 1979 to retain fire protection programs approved under BTP APCSB 9.5-1 and its Appendix A, except in three areas: safe-shutdown capability (including alternative or dedicated shutdown systems), emergency lighting, and the reactor coolant pump oil system. After several years of interaction with licensees implementing fire protection programs under 10 CFR 50.48, the NRC issued Generic Letter 86-10, “Implementation of Fire Protection Requirements” (Ref. 14). Among other things, GL 86-10 included a standard license condition on fire protection, which could be adopted by license amendment. Under the standard condition, a licensee may make changes to the approved fire protection program, without prior NRC approval, if the changes do not
