nd design elements in Chapter 3 of NFPA 805, the staff will review the LAR in accordance with 10 CFR 50.48(c)(2)(vii) and RG 1.205, Regulatory Position 2.2.2, to verify the adequacy of the methods and the licensee’s evaluation and conclusions. III.1.8 Risk-Informed, Performance-Based Alternatives to Compliance with NFPA 805 NFPA 805 provides one framework describing how RI/PB methods may be used to self-approve plant changes that affect the FPP. Other frameworks may be acceptable. Under 10 CFR 50.48(c)(4), a licensee may request NRC approval to use RI or PB alternatives (i.e., different from those prescribed by NFPA 805) to demonstrate compliance with 10 CFR 50.48(c) using the LAR process. In those instances, the staff will review the LAR in accordance with 10 CFR 50.48(c)(4) to verify that all of the following are true for the proposed alternative and its application: (a) It satisfies the performance goals, objectives, and criteria specified in NFPA 805 related to nuclear safety and radiological release; (b) It maintains safety margins; and, (c) It maintains fire protection DID (fire prevention, fire detection, fire suppression, mitigation, and post-fire safe-shutdown capability). 9.5.1.2-9 Rev. 0 – December 2009 Regulatory Position 2.2.3 of RG 1.205 provides additional guidance to licensees requesting staff approval for alternative RI/PB methods. Consistent with NEI 04-02, Revision 2, Section 2.4.1, the licensee should provide: (a) A detailed description of the alternative RI/PB method (b) A description of how the method will be applied, the aspects of the FPP to which it will be applied, and the circumstances under which it will be applied (c) The acceptance criteria, including risk increase acceptance criteria, that the licensee will apply when determining whether the results of an evaluation that uses this methodology meet the required NFPA 805 performance goals, performance objectives, and performance criteria (d) For risk assessments using PRA methods, a
