his guidance is generic and do not encompass all possible areas that contain radiological and fire hazards for a plant undergoing decommissioning. This guidance is applicable to a decommissioning fire protection program that implements protection methods described in this guide for plants that implement a performance-based or previously approved National Fire Protection Association (NFPA) 805 fire protection program. The methods of protection described in this appendix are not requirements of the U.S. Nuclear Regulatory Commission. Spent Fuel Pool Area and Other Plant Areas The fire hazards in the spent fuel pool area and other plant areas should be quantified if they present an exposure hazard or could propagate to the spent fuel pool area. The potential for these fire hazards to affect radioactive materials, including the spent fuel, should be evaluated. The radiological hazards in this area that could contribute to a radiological release if exposed to fire should be quantified, including hazards of the spent fuel and any radioactive waste or contamination. Potential releases of radioactive materials should be quantified by a conservative analysis of the fire-related source term, the capabilities of mitigating systems, and emergency response actions. Exposures resulting from the fire-induced release of radioactive materials should not exceed the limits of Title 10 of the Code of Federal Regulations (10 CFR) Part 20, “Standards for Protection Against Radiation.” Cables and equipment associated with structures, systems, and components (SSCs) that are necessary to protect the spent fuel and mitigate any radiological release should be evaluated and protected from the effects of fire, as appropriate. These systems may include building ventilation, spent fuel pool cooling and makeup, instrumentation and controls, and electrical power. Rated fire barriers should be maintained that provide separation between significant fire hazards and SSCs important to the safe
