bmit summaries of costs in a format that allows comparison to previous NRC studies of decommissioning costs. Radioactive waste disposal is a major cost factor in decommissioning; therefore, a licensee should submit relevant data on its radwaste projections. Suggested tabular formats are shown later in this section. The NRC uses information on the licensee’s decommissioning schedule for scheduling inspection resources. Therefore, a licensee should submit its decommissioning work schedule. The licensee should provide the following information to help NRC staff properly assess the estimate: 3.1 General Information ! A discussion of the decommissioning option chosen (DECON, SAFSTOR, or some combination thereof) ! A discussion of the methodology used to derive the cost estimates ! A summary of total decommissioning costs by phase. The costs of items not considered part of decommissioning (such as site restoration and spent nuclear fuel storage/management) should be listed separately. For the DECON option, the total decommissioning costs should be separated into the following or a similar set of decommissioning cost categories: • Major radioactive component removal -- reactor vessel and internals, steam generators, pressurizers, large-bore reactor coolant system piping, and other large components that are radioactive to a comparable degree • Radiological D&D -- removal of remaining radioactive plant systems, including radiological decontamination 13 • Management and support -- labor costs of support staff and decommissioning operations contractors (DOC) staff, energy costs, regulatory costs, small tools, insurance, etc. • LLW packaging -- placing LLW in packages • LLW shipping -- shipping LLW to waste vendors/burial site • LLW burial/waste vendor -- LLW burial charges, including LLW processing fees by waste vendors • Contingency -- allowance for unexpected costs For the SAFSTOR option, the decommissioning costs for the above cost categories should also be
