For shipments of radioactive waste, the number of shipments should be normalized to the 880-MW(e) reference reactor and a shipment capacity of 2.34 m3 per shipment should be used to estimate the number of shipments. For shipments of unirradiated fuel, the ER should first estimate the total number of shipments over a 40-year plant lifetime, accounting for the initial core load plus average annual reloads for a period of 39 years. The number of shipments should then be normalized to the 880-MW(e) reference reactor and the annual number of shipments estimated assuming a 40-year plant lifetime. 6.3 Decommissioning At the end of the operating life of a power reactor, NRC regulations require that the facility undergo decommissioning. The NRC defines decommissioning as the safe removal of a facility from service and the reduction of residual radioactivity to a level that permits termination of the NRC license. The regulations governing decommissioning of power reactors are found in 10 CFR 50.75, “Reporting and Recordkeeping for Decommissioning Planning” and 10 CFR 50.82, “Termination of License.” The radiological criteria for termination of the NRC license are in 10 CFR Part 20, Subpart E. Minimization of contamination and generation of radioactive waste requirements for facility
