not satisfied. As discussed in Section 4.2.2 of NFPA 805, the PB approach shall be permitted to utilize deterministic methods for simplifying assumptions within the fire area. If the fire modeling PB approach is employed, the staff will verify that the LAR commitments meet the requirements of NFPA 805, Section 4.2.4.1. The staff will verify that the licensee has made a statement in the LAR confirming that it has provided the operational guidance required by NFPA 805, Section 4.2.4.1.6, and that all RAs are feasible. NUREG-1852 is one acceptable PB approach that can be used in judging the feasibility of RAs. Another acceptable set of criteria that a licensee may use to evaluate the feasibility of RAs is outlined in NFPA 805, Appendix B.5.2(e). If the fire risk evaluation PB approach is employed, the staff will review the integrated assessment of the acceptability of risk, DID, and safety margins per Section III.5.5 of this SRP. The staff will review OMAs that the licensee desires to transition to RAs. If the licensee has 9.5.1.2-14 Rev. 0 – December 2009 chosen to use the PB approach because the licensee credits RAs to demonstrate the availability of a success path for the nuclear safety performance criteria, the staff will review the licensee’s evaluation of the additional risk per Section III.5.4 of this SRP. III.3.2.3 Risk-Informed or Performance-Based Alternatives to Compliance with NFPA 805 For each fire area where the licensee has selected RI or PB alternatives to compliance with NFPA 805, the staff will verify that the LAR commitments meet the appropriate requirements. Refer to Paragraph III.1.8 of this SRP Section for information relating to these alternatives. III.3.3 Non-Power Operational Modes The staff will review the licensee’s treatment of fires during non-power operations (NPOs). As stated in RG 1.205, Regulatory Position 2.2.5, Section 4.3.3 and Appendix F to NEI 04-02 provide detailed guidance on one acceptable approach to addressing fires
