d • NUREG/CR-7002, Revision 1, “Criteria for Development of Evacuation Time Estimate Studies,” issued February 2021 (Ref. 50); 1.5.3 Considerations, Regulatory Experience, and Staff Position NRC requirements pertaining to emergency planning were first developed in 10 CFR Part 50 ( §50.47 and Appendix E) with respect to construction permits and operating licenses. Emergency planning requirements for ESPs and COLAs are contained in 10 CFR Part 52 Subpart A, and 10 CFR Part 52 Subpart C, respectively. NRC reviews and approves emergency plans in consultation with the Federal Emergency Management Agency (FEMA), as described in NUREG-0654/FEMA-REP-1. In 10 CFR 50.47(a)(1), the NRC requires a reasonable assurance finding that adequate protective measures can and will be taken in a radiological emergency. Emergency plans must include information at sufficient levels to allow the Commission to make its determination. The regulation in 10 CFR 50.47(b) includes 16 elements that must be included in the emergency plans. These elements include, but are not limited to, procedures for requesting offsite assistance, communications, and the conduct of exercises that demonstrate the ability to respond to emergencies. 10 CFR 50.47(d) allows issuance of an operating license authorizing only fuel loading or low-power testing and training (up to 5 percent of the rated power) without certain NRC or Federal Emergency Management Agency reviews, findings, or determinations concerning the state of offsite emergency preparedness. Adequate plans must be developed for two areas, or emergency planning zones (EPZs): the plume exposure pathway EPZ and ingestion pathway EPZ. As stated in 10 CFR 50.47, the plume exposure pathway EPZ for nuclear power plants generally consists of an area about 16 kilometers (km) (10 miles (mi)) in radius, and the ingestion pathway EPZ generally consists of an area about 80 km (50 mi) in radius. The exact size and configuration of the EPZs should be determined in
