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 the decommissioning option chosen (DECON, SAFSTOR, or some combination thereof), with identification of major factors that could impact the cost of decommissioning. ! 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 demolition 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 • Management and support (undistributed costs) -- labor costs of support staff and 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 separated into the following, or a similar set of decommissioning phases (time periods): • Pre-decommissioning engineering and planning/plant deactivation -- all activities from engineering and planning through defueling and layup to completing the placement of the reactor into permanent shutdown condition • Extended safe storage operations -- safe storage monitoring of the
