tion 2.1, should be explained. ! 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 10 • Management and support (undistributed costs) -- labor costs of support staff and decommissioning operations contractor (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 pre-decommissioning engineering and planning through defueling, plant layup, and placement of the reactor into a permanent shutdown condition • Extended safe storage operations -- safe storage monitoring of the facility until dismantlement begins (If storage or monitoring of spent fuel is included in the cost estimate, it should be shown separately.) • Final radiological D&D -- radiological D&D of radioactive systems and structures required for license termination, including demolition for the purposes of reducing residual radioactivity (If demolition of uncontaminated 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.
