the staff will verify that the LAR commitments meet the deterministic requirements of NFPA 805, Section 4.2.3. Note that certain RAs do not constitute deterministic compliance and require use of a PB approach, whether or not part of a plant’s existing licensing basis, as discussed in Section III.1.3. Licensees may demonstrate compliance through: (a) Compliance with the deterministic requirements of NFPA 805 through the use of previously approved exemptions/deviations from their current licensing basis; or, (b) The use of an engineering equivalency evaluation of an existing configuration to demonstrate an equivalent level of fire protection compared to the deterministic requirements. [NFPA 805, Section 2.2.7] Previously approved exemptions/deviations (normally from Appendix R requirements) describe plant configurations that the staff has determined to be acceptable, notwithstanding that Appendix R or NFPA 805 may require some other configuration. Such plant configurations may be deemed to satisfy the deterministic requirements of NFPA 805 provided the basis for acceptability of these previously approved exemption/deviations continues to be valid. Guidance for acceptable existing engineering equivalency evaluations (EEEEs) is provided in RG 1.205, Regulatory Position 2.3.2 and NEI 04-02, Appendix B.3. Submittal of EEEEs for NRC review and approval should be as discussed in the RG 1.205, Regulatory Position. III.3.2.2 Performance-Based Compliance with NFPA 805, Section 4.2.4 For each fire area where the licensee has selected the PB approach, the staff will verify that the LAR commitments meetthe requirements of NFPA 805, Section 4.2.4. A PB approach is necessary if the deterministic requirements of NFPA 805, Section 4.2.3, (as discussed in Section III.3.2.1) are 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
