Content:
entify which systems, components, and flow paths are used to meet the release criteria; (2) the identification of FPP elements, including measures, systems, procedural control actions, and flow paths, credited to meet the criteria; (3) a description of plant programs, such as fire brigade training and equipment maintenance, that are relied upon to sustain equipment reliability and fire brigade performance; and (4) a bounding analysis, qualitative risk analysis, or quantitative risk analysis that demonstrates that the release criteria have been met. Section 4.3.4 and Appendix G to NEI 04-02 provide additional information and guidance related to this topic. RG 1.205, Revision 2, Page 13 2.2.7 Monitoring Program NFPA 805 requires licensees to establish a monitoring program to ensure the availability and reliability of the fire protection systems and features, assess the performance of the FPP in meeting the performance criteria, and ensure the assumptions in the engineering analyses remain valid. Section 5.2 and Appendix G of NEI 04-02 provide detailed guidance on one acceptable approach to establishing an appropriate monitoring program. 2.3 Carryover of Current Fire Protection Programs into NFPA 805 In certain cases, the NRC may have granted exemptions or deviations that are reflected in the licensee’s current FPP that would be acceptable alternatives to the NFPA 805 requirements. If the NRC has previously approved such alternatives, licensees should reference documentation of that approval. Elements of a licensee’s pre-transition fire protection licensing bases that can be shown to meet NFPA 805 requirements, including approved exemptions, deviations, and safety evaluation reports, are not “changes to a previously approved FPP” and would not be included in 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
