ied events and conditions. The statements of considerations for the 10 CFR 50.72 and 10 CFR 50.73 final rules include additional reporting guidance. 1.8.6 National Fire Protection Association Code and Standard Deviation Evaluations For those fire protection SSCs installed to satisfy the NRC requirements and designed to NFPA codes and standards, the code of record is the code edition in force at the time of the design or at the time the commitment is made to the NRC for a fire protection feature. The FSAR or the fire hazards analysis should identify and justify deviations from the codes. Deviations should not degrade the performance of fire protection systems or features. As stated in SRP 9.5.1.1, Appendix A Section 3, the standards of record related to the design and installation of fire protection systems and features required to satisfy NRC requirements in all new reactor designs are those NFPA codes and standards in effect 180 days before the submittal of the application under 10 CFR Part 50 or 10 CFR Part 52. The 180-day deadline is based on the application requirements in 10 CFR 50.34(h)(1)(i), 50.34(h)(1)(ii), 52.47(a)(9), 52.79(a)(41), 52.137(a)(9), and 52.157(f)(30). A licensee may apply the equivalency concept in meeting the provisions of the NFPA codes and standards. Nothing in the NFPA codes or standards is intended to prevent the use of methods, systems, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety as alternatives to those prescribed by the codes or standards, provided that technical documentation demonstrates equivalency and the method, system, or device is listed or approved for the intended purpose. DG-1359, Page 38 An exemption is not required to deviate from NFPA codes, except as required for NFPA codes referenced in NRC regulations such as NFPA 805 in 10 CFR 50.48(c). The NRC guidelines reference certain NFPA codes as providing guidance acceptable to the staff; therefore, such codes
