do not adopt a program based on NFPA 805 may use risk-informed, performance-based methods to determine the acceptability of a plant change; however, licensees should submit the methodology, including acceptance criteria, for NRC review and approval as a license amendment request (LAR), in accordance with 10 CFR 50.90, “Application for Amendment of License, Construction Permit, or Early Site Permit,” before implementing the change. In addition, the staff notes that RG 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis” (Ref. 19), provides guidance on this topic. • RG 1.188, “ Standard Format And Content For Applications To Renew Nuclear Power Plant Operating Licenses” (Ref. 20), describes an approach that is acceptable to the NRC staff for the format and content of an application to renew or subsequently renew an NRC-issued operating license under 10 CFR Part 54, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants” (Ref. 21). • Regulatory Issue Summary (RIS) 2005-07, “Compensatory Measures to Satisfy the Fire Protection Program Requirements,” dated April 19, 2005 (Ref. 22), describes how licensees may use alternate approaches when the measures specified in the approved FPP do not ensure an appropriate level of safety for the specific circumstances. • RIS 2005-30, “Clarification of Post-Fire Safe-Shutdown Circuit Regulatory Requirements,” dated December 20, 2005 (Ref. 23), clarifies regulatory requirements related to postfire safe-shutdown circuit analysis and protection. This revision of this regulatory guide provides the current guidance on how a licensee may address circuit analysis issues. • RIS 2006-10, “Regulatory Expectations with Appendix R Paragraph III.G.2 Operator Manual Actions,” dated June 30, 2006 (Ref. 24), informs licensees about the staff’s expectations, schedule, and enforcement policy for resolving issues
