formance-based, technology-inclusive, risk-informed, and consequence-oriented approach to EP that provides an alternative to the EP requirements under 10 CFR 50.47. Background Prior to the issuance of the EP requirements in 10 CFR 50.160, the NRC relied on EP regulations initially developed for large light-water reactors (LWRs) and non-power reactors, also referred to as research and test reactors (RTRs). Historically, small LWR and non-LWR applicants requested exemptions from some of the emergency planning requirements in 10 CFR 50.47 and Appendix E to 10 CFR Part 50 (e.g., La Crosse, Big Rock Point, Fort St. Vrain). Alternatively, certain license applicants could request to be evaluated on a case-by-case basis, as described in 10 CFR 50.47(c)(2). The EP requirements in 10 CFR 50.160 acknowledge technological advancements and other differences from large LWRs that are inherent in SMRs and other new technologies (ONTs).1 With the addition of 10 CFR 50.160, the NRC has addressed the differences in emergency planning and response between large LWRs and SMRs, non-LWRs, and NPUFs. Section 50.160 establishes an approach to EP that focuses on performance and results, rather than control of emergency plans and procedures. This RG applies to applicants and licensees choosing the performance-based approach to EP. Small modular reactor, non-LWR, and NPUF applicants and licensees may choose to adopt either the requirements of 10 CFR 50.160 or those in Appendix E to 10 CFR Part 50 and, for nuclear power reactor licensees, the planning standards in 10 CFR 50.47. Existing guidance in NUREG-0654/FEMA-REP-1 addresses implementation of EP programs under 10 CFR 50.47 and Appendix E to 10 CFR Part 50. Existing guidance in RG 2.6 addresses implementation of NPUF EP programs under Appendix E to 10 CFR Part 50. The requirements of 10 CFR 50.33(g) specify that nuclear power reactor applicants must describe in their emergency plans actions as are appropriate to protect the food ingestion
