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 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. ! A comparison of the estimated cost with the minimum financial assurance (MFA) funding requirement discussed in Regulatory Position 2.1. ! A discussion of the plans for adjusting the level of funds in the trust should be included to demonstrate that funds will be available for use when needed if the decommissioning trust is not fully funded. 3.2. A Description of the Overall Decommissioning Project The description should include: ! A detailed work breakdown that describes all the activities to be performed, including planning and preparation. ! An inventory of contaminated components that require radiological decontamination or decommissioning. A suggested format for providing this information is shown in Table 3. The inventory should be a summary of components, not an itemized listing. ! Maps or diagrams showing areas of concrete and metal surfaces
