proposed methodologies, including the acceptance criteria, should be reviewed and approved by the NRC prior to the implementation of the plant change. 10 CFR Part 52.47(a)(v) requires that new reactor applications submitted under Part 52 include a design specific probabilistic risk assessment. A detailed fire PRA is not necessarily required for a new reactor FPP. However, if a COL applicant references a DC and if that certified design developed a fire PRA, then the COL applicant, per proposed 10 CFR 52.80(a), is to use that PRA and update it to reflect site and plant-specific information that may not have been available at the design stage. In addition, a licensee that has a risk-informed, performance-based FPP (similar to an NFPA 805 program) or that plans to evaluate plant changes using a risk-informed approach should have a detailed fire PRA. The term “fire PRA” encompasses all levels and types of PRAs, ranging from a simplified bounding analysis to a detailed analysis in accordance with NUREG/CR-6850 and the draft American Nuclear Society Fire PRA Standard. NUREG/CR-6850 should provide the basis for the review of the proposed methodologies. Refer to SRP Chapter 19, “Probabilistic Risk Assessment,” for additional guidance on the review of nuclear power plant PRAs. A fire PRA should be subjected to a peer review to the extent that adequate industry guidance is available. The industry guidance will be reviewed and, if appropriate, accepted by the NRC prior to its application to specific fire PRAs. The results of the plant-specific peer reviews should also be reviewed by the NRC. A peer review should be conducted for all types and levels of fire PRAs. In the event that adequate industry guidance is not available for conducting a fire PRA peer review, the NRC should review the fire PRA for acceptability. Licensees may use PRA and/or risk insights gained from other methods in support of proposed changes to the plant licensing basis, such as license amendment
