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 purpose 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. 12 2.4 Site-Specific Cost Estimates in the PSDAR The estimate of expected decommissioning costs required for the PSDAR can be the same as the site-specific cost estimate required by 10 CFR 50.82(a)(8)(iii). The site-specific cost estimate is a very detailed assessment that incorporates the cost impact of site-specific factors. The site-specific estimate is discussed in Regulatory Position 3. 3. SITE-SPECIFIC COST ESTIMATE A site-specific cost estimate is required by 10 CFR 50.82(a)(8)(iii) to be submitted within two years following permanent cessation of operations. This cost estimate may be included with the PSDAR (10 CFR 50.82(a)(4)(i)). In addition, a site-specific estimate may be submitted at the discretion of the licensee when a higher funding level than that calculated in the formula in 10 CFR 50.75(c) is desired. A licensee typically will be required by its rate regulators to provide extensive detail regarding decommissioning costs. However, the NRC does not require the same level of detail for cost data. Licensees should submit 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
