risk-informed, performance-based FPP licensing actions submitted pursuant to 10 CFR 50.48(c). • NUREG-1852, “Demonstrating the Feasibility and Reliability of Operator Manual Actions in Response to Fire,” issued October 2007 (Ref. 16), provides the technical bases in the form of criteria and technical guidance that may be used to demonstrate that operator manual actions are feasible and can be performed reliably under a wide range of plant conditions that an operator might encounter during a fire. • NUREG/CR-7135, “Compensatory and Alternative Regulatory Measures for Nuclear Power Plant Fire Protection (CARMEN-FIRE),” issued August 2015 (Ref. 17), provides information related to interim compensatory measures and consolidates several NRC communications and technical documents on using compensatory measures to protect against fire at commercial nuclear power plants. • RG 1.191, “Fire Protection Program for Nuclear Power Plants During Decommissioning and Permanent Shutdown” (Ref. 18), provides specific criteria and guidelines for FPPs for the shutdown and decommissioning of nuclear power plants. In addition, 10 CFR 50.48(f) notes that an FPP that complies with NFPA 805 shall be deemed to be acceptable for complying with the regulatory requirements for fire protection of plants that have been decommissioned and permanently shut down. DG-1359, Page 5 • RG 1.205 will take precedence over the guidance in this RG for plants that adopt a risk-informed, performance-based FPP in accordance with 10 CFR 50.48(c). For plants that do not modify their licenses in accordance with 10 CFR 50.48(c), the NRC staff may accept risk-informed and performance-based alternatives to the guidance presented in this document that are in accordance with RG 1.205. Licensees that 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
