Revision 4 - October 2003 43 APPENDIX A: Supplemental Fire Protection Review Criteria for Shutdown and Decommissioned Reactors A. INTRODUCTION This appendix provides addition guidelines for review of fire protection programs and related submittals for nuclear power plants that have ceased operations and processed the necessary certifications under 10 CFR Part 50, §50.82(a)(1) and is based on the information and guidelines provided in Regulatory Guide 1.191. B. DISCUSSION The primary objective of the fire protection program for operating reactors is to limit fire damage to structures, systems, and components (SSCs) important to safety, to ensure the capability to safely shut down the reactor and maintain it in a safe shutdown condition. For those plants that have permanently ceased operations and removed fuel from the reactor vessel, the safe shutdown requirements of 10 CFR Part 50.48(a)(2)(iii), and Appendix R to 10 CFR Part 50, are no longer applicable. The primary fire protection concern for permanently shut down plants is protecting the integrity of the spent fuel and preventing, or minimizing, the release of radioactive materials resulting from fires involving contaminated plant SSCs or radioactive wastes. The radiation dose limits specified in 10 CFR Part 20, "Standards for Protection Against Radiation," apply for plant personnel and members of the public for fire incidents at permanently shutdown nuclear power plants. Licensees should make every effort to maintain exposures to radiation resulting from a fire as low as reasonably achievable. The fire protection program for the operating reactor provides the baseline for the decommissioning phase. Licensees that have permanently shut down their nuclear power plant(s), and have made the necessary decommissioning submittals to the NRC as required by 10 CFR Part 50.82, have the option of beginning immediate decommissioning and dismantlement of the facility or may choose to place the facility in a monitored storage
