eptions, and allows licensees to apply for a license amendment to comply with the 2001 Edition of NFPA 805. In parallel with the Commission’s efforts to issue a rule incorporating the risk-informed, performance-based fire protection provisions of NFPA 805, NEI published implementing guidance for the specific provisions of NFPA 805 and 10 CFR 50.48(c) in NEI 04-02. RG 1.205, Revision 1, endorsed, with clarifications and exceptions, NEI 04-02, Revision 2. This revision of the RG (Revision 2) updates the previous staff positions in RG 1.205, Revision 1, and endorses NEI 04-02, Revision 3. This RG also offers additional information and guidance to supplement the NEI document and assist licensees in RG 1.205, Revision 2, Page 5 meeting the NRC’s regulations in 10 CFR 50.48(c) related to adopting a risk-informed, performance- based FPP. NEI 04-02, Revision 3, provides detailed guidance applicable to many of the regulatory requirements of 10 CFR 50.48(c) and NFPA 805. This guide sets forth regulatory positions, emphasizes certain issues, clarifies the requirements of 10 CFR 50.48(c) and NFPA 805, clarifies the guidance in NEI 04-02, and modifies the NEI 04-02 guidance where required. Should a conflict occur between NEI 04-02 and this RG, the regulatory positions in this guide govern. References to NEI 04-02 in this regulatory guide refer to Revision 3 of that NEI document. References to NEI 00-01 in this regulatory guide refer to Revision 4 of that NEI document. Fire Protection Program Changes Before the issuance of 10 CFR 50.48(c), plants typically adopted a standard fire protection license condition. Under this condition, the licensee could make changes to the approved FPP without prior NRC approval only if the changes would not adversely affect the plant’s ability to achieve and maintain safe shutdown in the event of a fire. In 10 CFR 50.48(c), the NRC requires licensees choosing to adopt NFPA 805 to identify license conditions to be revised or superseded.
