52, “Environmental Effects of Transportation of Fuel and Waste,” which summarizes the environmental impacts of transportation of fuel and waste to and from one 3,000 to 5,000 MW(t) [1,000 to 1,500 MW(e)] LWR. Impacts are provided for normal conditions of transport and accidents in transport for a reference 1,100-MW(e) LWR. Dose to transportation workers during normal transportation operations was estimated to result in a collective dose of 4 person-rem per reference reactor-year. The combined dose to the public along the route and the dose to onlookers were estimated to result in a collective dose of 3 person-rem per reference reactor-year. Environmental risks of radiological effects during accident conditions, as stated in Table S-4, are small. Nonradiological impacts from postulated accidents were estimated as one fatal injury in 100 reference reactor-years and one nonfatal injury in 10 reference reactor-years. The NRC has generically considered the environmental impacts of spent nuclear fuel with uranium-235 enrichment levels up to 5 percent and irradiation levels up to 62,000 MWd/MTU and found that the environmental impacts of spent nuclear fuel transport are bounded by the impacts listed in 10 CFR 51.52, Table S-4, provided that more than 5 years has elapsed between removal of the fuel from the reactor and shipment of the fuel offsite (see License Renewal GEIS 1996 and Addendum 1). However, these analyses apply to license renewal and cannot serve as the initial licensing basis for new reactors. The detailed requirements for the analysis of environmental impacts involving the transportation of radioactive materials to and from nuclear power reactors are contained in 10 CFR Part 51. In accordance with 10 CFR 51.52(a), a full description and detailed analysis of transportation impacts are not required when licensing a LWR, if the reactor meets the following criteria: DG-4.2, Page 117 • The reactor has a core power level that does not exceed 3,800 MW(t). •
