ncontaminated structures and site restoration activities are included in the cost estimate, they should be shown separately.) A suggested format for providing this information is presented in Table 2. 2.3 Generic Cost Estimate As discussed in Regulatory Guide 1.185 (Ref. 2), the PSDAR estimate of expected decommissioning costs can be based on a generic cost estimate. Generic information would be particularly acceptable if a licensee has chosen extended safe storage of the facility followed by radiological D&D, since cost estimates of final dismantlement would occur far in the future and would therefore be highly uncertain. The generic cost estimate may be based on best estimates prepared by the NRC for reference nuclear power plants (i.e., NUREG/CR-0130, “Technology, Safety and Costs of Decommissioning a Reference Pressurized Water Reactor Power Station”; NUREG/CR-0672 (including Addenda 1 through 4), “Technology, Safety and Costs of Decommissioning a Reference Boiling Water Reactor Power Station”; NUREG/CR-5884, “Revised Analyses of Decommissioning for the Reference Pressurized Water Reactor Power Station”; and NUREG/CR-6174, “Revised Analyses of Decommissioning for the Reference Boiling Water Reactor Power Station” (Refs. 6—9)), or on other publicly available sources or other decommissioning cost estimates previously submitted to the NRC. However, factors such as inflation, regulatory changes, differences in thermal power rating, changes in waste disposal costs and disposal facility availability, and differences in the extent and kind of contamination at the site may cause the estimated cost to differ from the generic decommissioning cost used as the basis for the estimate of expected decommissioning costs. The estimate of 11 expected decommissioning costs based on a generic cost estimate will generally be substantially less detailed than the site-specific cost estimate. The generic cost estimate should consist of the following: ! A discussion of
