in its licensing basis is still the “code of record.” Licensees are not expected to comply with later editions of these codes and standards, except when they specifically adopt a later edition in accordance with regulatory guidelines or install new fire protection systems protecting SSCs important to safety. The code of record for the new fire protection system should be the edition that is in effect when the system is designed or when a DG-1370, Page 8 commitment to add the system is made to the staff. The code of record for any unchanged fire protection systems will not change. In general, for modifications to an existing fire protection system that are permitted by the code of record the system will not be required to be brought into compliance with the most recent edition of the code. The existing fire protection program for a given nuclear power plant may include additional NFPA and industry codes and standards. The licensee should review compliance with existing program codes and standards should be reviewed with due consideration of existing license commitments and conditions and the fire protection design basis of the specific plant. 1.3 Transition from Operating Plant Fire Protection Program Operating plants are required to have a fire protection program in accordance with the requirements of 10 CFR 50.48 and Criterion 3 of Appendix A to 10 CFR Part 50. The primary objective of the operating plant fire protection program is to provide defense-in-depth protection of the capability to shutdown the reactor and maintain it in a safe-shutdown condition. As the plant enters decommissioning, the needs for fire protection change. Most notably, the safe-shutdown objective is not applicable during decommissioning, because the reactor permanently shuts down and the fuel is removed from the reactor vessel as the final step before the plant enters decommissioning. However, many of the elements of the operating plant fire protection program continue to be relevant
