etion, however, a power reactor licensee may submit a certification based either on the formulas provided in 10 CFR.75(c)(1) and (2) or, when a higher funding level is desired, on a site-specific cost estimate that is equal to or greater than that calculated in the formula in 10 CFR 50.75(c)(1) or (2). ! 10 CFR 50.82(a)(9)(ii)(F) requires that a licensee provide “[a]n updated site-specific estimate of remaining decommissioning costs...” as part of a License Termination Plan (LTP). 10 CFR 50.82(a)(9)(i) requires that a licensee must submit its LTP at least two years before termination of the license date. As provided in 10 CFR 50.82(a)(8)(ii), a licensee may withdraw funds from the decommissioning trust fund up to a cumulative total of 3 percent of the generic amount calculated under 10 CFR 50.75(c) for decommissioning planning purposes at any time without prior notification to the NRC. After submittal of the certifications of permanent shutdown and fuel removal required under 10 CFR 50.82(a)(1) and commencing 90 days after the NRC has received the PSDAR, the licensee may use an additional 20 percent of the decommissioning funds prescribed in 10 CFR 50.75(c) for decommissioning purposes. The licensee is prohibited from using the remaining 77 percent of the generic decommissioning funds unless and until a site-specific decommissioning cost estimate is submitted to the NRC. In addition, use of any of the decommissioning funds is limited by 10 CFR 50.82(a)(8)(i) to legitimate radiological decommissioning expenses that neither reduce the value of the trust fund below that necessary to place and maintain the reactor in a safe storage condition, nor inhibit the ability of the licensee to complete funding of the trust to ultimately release the site and terminate the license. For example, use of the decommissioning trust fund for expenses related to storage of the spent fuel is prohibited unless the fund has been specifically structured into separate subaccounts to cover
