The NRC endorsed this guidance in a memorandum to NEI, “U.S. Nuclear Regulatory Commission Review and Endorsement of NEI 99-01, Revision 5,” February 22, 2008 (Ref. 23). • NEI 99-01, Revision 6, “Development of Emergency Action Levels for Non-Passive Reactors,” November 2012 (Ref. 24), which the staff found acceptable for use by licensees and applicants as a methodology to develop or upgrade EAL schemes in accordance with the requirements of 10 CFR 50.47(b)(4), related sections of Appendix E to 10 CFR Part 50, and the associated planning standard evaluation elements of NUREG-0654/FEMA-REP-1, Revision 1. The NRC endorsed this guidance in a memorandum to NEI, “U.S. Nuclear Regulatory Commission Review and Endorsement of NEI 99-01, Revision 6,” March 28, 2013 (Ref. 25). Since the publication of RG 1.101, Revision 6, the NRC has developed or endorsed several new or revised emergency planning guidance documents described in Section C of this RG. Background of NUREG-0654/FEMA-REP-1 Planning standard 10 CFR 50.47(b)(4) requires that the emergency plan include a standard EAL scheme. An EAL is a predetermined, site-specific, observable threshold for a plant condition that results in an emergency classification. The NRC initially established guidance for the development of EALs in Generic Letter (GL) 79-50, “Emergency Plans Submittal Dates,” issued 1979 (Ref. 26). In November 1980, the NRC published NUREG-0654/FEMA-REP-1, Revision 1, a joint NRC NUREG-series publication and Federal Emergency Management Agency (FEMA) guidance document. The NRC uses this document to evaluate the adequacy of the emergency plans and preparedness of nuclear power plant licensees. FEMA uses this document to review and approve State, local, and Tribal government radiological emergency plans. In October 1981, the NRC endorsed NUREG-0654/FEMA-REP-1, Revision 1, in RG 1.101, Revision 2, including guidance in Appendix 1 to NUREG-0654/FEMA-REP-1 that became the primary standard for the
