ether or not currently allowed or previously approved in the plant’s existing licensing basis, automatically shall imply use of the PB approach as outlined in NFPA 805, Section 4.2.4. The staff will verify that these OMAs have been evaluated using PB methods. Assessing the risk of these RAs is discussed in SRP Section III.5.4, “Risk of Crediting Recovery Actions.” III.3.2 Specific Compliance with NFPA 805 by Fire Area In evaluating nuclear safety performance criteria transition, staff will reference Section 1.5 of NFPA 805, which establishes the nuclear safety performance criteria, and Chapter 4 of NFPA 805, which provides the methodology to determine the fire protection systems and features required to achieve the performance criteria outlined in Section 1.5. The staff will review the LAR to ensure that each fire area has been evaluated and determined to comply with the requirements of NFPA 805. The staff will verify that each fire area either meets NFPA 805, Section 4.2.3 deterministic requirements; meets the NFPA 805, Section 1.5 performance criteria as demonstrated by using PB methods as allowed under NFPA 805, Section 4.2.4; or meets the NFPA 805, Section 1.5 performance criteria as demonstrated using 9.5.1.2-13 Rev. 0 – December 2009 RI or PB alternatives to compliance with NFPA 805 pursuant to 10 CFR 50.48(c)(4). When using the PB approach of NFPA 805, Section 4.2.4, the user shall be permitted to utilize deterministic methods for simplifying assumptions within the fire area as allowed by Section 4.2.2. Refer to Paragraph III.1.8 of this SRP Section for further information on alternatives. III.3.2.1 Deterministic Compliance with NFPA 805, Section 4.2.3 For each fire area where the licensee has selected the deterministic approach to demonstrate compliance, 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
