ard conditions, such as those associated with maintenance and refueling activities. The licensee should implement appropriate compensatory measures, such as fire watches or temporary fire barriers, to ensure adequate fire protection and reactor safety. For those plants that are permanently shutdown, are undergoing decommissioning, or both, the licensing basis changes in accordance with the requirements in 10 CFR 50.82, “Termination of License.” For permanently shutdown reactors, 10 CFR 50.48(f) and RG 1.191 relate to fire protection. The objectives of the FPP listed in 10 CFR 50.48(f)(1) are to: (1) reasonably prevent fires from occurring, (2) rapidly detect, control, and extinguish those fires that do occur and that could result in a radiological hazard, and (3) ensure that the risk of fire-induced radiological hazards to the public, environment, and plant personnel is minimized. In addition, 10 CFR 50.48(f) notes that an FPP that complies with NFPA 805 shall be deemed acceptable for complying with the regulatory requirements for the fire protection of plants that have been decommissioned or permanently shut down. The following sections provide guidance on fire prevention measures, including control of combustibles and ignition sources and housekeeping inspections. Regulatory Position 1.1 discusses organizational responsibilities for implementing fire prevention measures. Portions of NFPA 1, “Fire Code” (Ref. 55), contain additional guidance that may be used to develop and implement fire prevention measures. 2.1 Control of Combustibles Administrative controls for fire prevention should include procedures to control handling and use of combustibles, prohibit storage of combustibles in plant areas important to safety, establish designated storage areas with appropriate fire protection, and control use of specific combustibles (e.g., wood) in plant areas important to safety.
