rse effect on the ability of the passive systems to perform the safe shutdown function. 4. Applicable Industry Codes and Standards Revision 4 - October 2003 52 The fire protection program for advanced light water reactor designs should comply with the provisions specified in NFPA 804, “Fire Protection for Advanced Light Water Reactors” related to the protection of post-fire safe shutdown capability and the mitigation of a radiological release resulting from a fire. The standards of record related to the design and installation of fire protection systems and features required to satisfy NRC requirements in all advanced reactor designs are those NFPA codes and standards in effect 180 days prior to the submittal of the application under 10 CFR Part 50 or 10 CFR Part 52. 5. Other New Reactor Designs Fire protection programs for proposed new non-light water reactor designs should meet the overall fire protection objectives outlined in the BTP related to safe shutdown and radiological release. Fire hazards should be identified, evaluated, and an appropriate level of protection provided to meet these objectives. Design reviews and testing programs should confirm the safe shutdown capability. Structures, systems, and components important to safe shutdown should be protected in accordance with the enhanced criteria described below. Fire protection systems and features should be consistent with the BTP criteria as determined necessary by a fire hazards analysis. Similar to the enhanced fire protection criteria previously discussed in Section 1 of this appendix for ALWRs, the following performance criteria applies to the review of other new reactor designs: New reactor designs must ensure that safe shutdown can be achieved assuming that all equipment in any one fire area will be rendered inoperable by fire and that re-entry into the fire area for repairs and operator actions is not possible. Because of its physical configuration, the control room is excluded from this
