s The FPPs for licensees that submit applications in accordance with 10 CFR Part 52 are subject to 10 CFR 50.48(a). The staff developed recommended criteria for enhanced fire protection, in accordance with SECY-90-016, “Evolutionary Light-Water Reactor (LWR) Certification Issues and Their Relationship to Current Regulatory Requirements” (Ref. 32); SECY-93-087, “Policy, Technical, and Licensing Issues Pertaining to Evolutionary and Advanced Light Water Reactor (ALWR) Designs” (Ref. 33); and SECY-94-084, “Policy and Technical Issues Associated with the Regulatory Treatment of Non Safety Systems in Passive Plant Designs” (Ref. 34). SECY-90-016 recommended enhanced fire protection criteria for evolutionary light-water reactors. SECY-93-087 recommended that the enhanced criteria be extended to include passive reactor designs. The Commission approved SECY-90-016 and SECY-93-087 in staff requirements memoranda (Refs. 35 and 36). SECY-94-084, in part, establishes criteria defining safe-shutdown conditions for passive light-water reactor designs and is discussed in a staff requirements memorandum (Ref. 37). Currently, the NRC staff uses the guidance and acceptance criteria in NUREG-0800, Chapter 9, SRP Section 9.5.1.1 to review Part 52 FPPs. Consideration of International Standards The International Atomic Energy Agency (IAEA) works with member states and other partners to promote the safe, secure, and peaceful use of nuclear technologies. The IAEA develops Safety Standards and Safety Guides for protecting people and the environment from harmful effects of ionizing radiation. This system of safety fundamentals, safety requirements, safety guides, and other relevant reports reflects an international perspective on what constitutes a high level of safety. To inform its development of this RG, the NRC considered IAEA Safety Requirements and Safety Guides1 pursuant to the Commission’s International Policy Statement (Ref. 38) and Management Directive and Handbook
