ludes a license condition permitting self approval of future changes to the FPP, the staff will verify that the proposed license condition limits the risk increase from any individual change such that there is reasonable assurance that the effect of self-approved changes on cumulative risk will be acceptable. [RG 1.205, Regulatory Position 3.2.5] Section 2.4.4.1 further states that if more than one plant change is combined into a group for the purposes of evaluating acceptable risk, the evaluation of each individual change shall be performed along with the evaluation of combined changes. Any risk increases may be combined with risk decreases when estimating the total risk change. The staff will evaluate the licensee’s combined changes as combined change requests as described in RG 1.174 and SRP Section 19.2. RG 1.205, Regulatory Position 3.2.5 provides guidance for combining changes. III.6 MONITORING PROGRAM Section 2.6 of NFPA 805 requires licensees to establish and monitor acceptable levels of availability, reliability, and performance of fire protection systems and features. Monitoring methods are required to consider plant and industry operating experience. If the established levels of availability, reliability, or performance are not met, appropriate corrective actions to return to the established levels shall be implemented. NEI 04-02, Section 4.5.3 and Appendix E, provide guidance to licensees, acceptable to the staff, for implementing the required monitoring program. The staff will review the licensee’s proposed program to ensure the program adequately addresses the endorsed guidance. 3 Unless circumstances indicate that a backfit under 10 CFR 50.109 is warranted on an adequate protection or cost-beneficial safety improvement basis. Any actions to impose a backfit would take place independent of the licensing action under consideration, per 10 CFR 50.109(d), which states: “No licensing action will be withheld during the pendency of backfit analyses
