estimates of future inflation but only of inflation that has already occurred, licensees should recalculate the certification amount each year using the previous year’s data, as described in 10 CFR 50.75(c)(2). This recalculation is for certification purposes only and does not affect estimated future inflation that a licensee may calculate to establish amortization or collection schedules for rate-making or other purposes. Applicants and licensees who have prepared a site-specific decommissioning cost estimate should also annually prepare adjustments to the cost estimate, but these adjustments need not be submitted to the NRC (see Regulatory Position C.1.4). Updated calculations based on the formulas in 10 CFR 50.75(c) or on site-specific decommissioning cost estimates, as appropriate, for power reactor licensees are to be submitted every 3 years (and in certain cases annually) to the NRC as part of the report required in 10 CFR 50.75(f)(1). 1.3 Decommissioning Cost Estimates For power reactor licensees, five decommissioning cost estimates are required to be developed and submitted for NRC review: (1) initial estimate that may be calculated according to 10 CFR 50.75(c), or that may be site-specific and at least equal to the decommissioning cost from 10 CFR 50.75(c); (2) preliminary site-specific decommissioning cost estimate at or about 5 years before the projected end of operations, in accordance with 10 CFR 50.75(f)(2); (3) site-specific decommissioning cost estimate contained in the PSDAR, in accordance with 10 CFR 50.82(a)(4)(i) or 10 CFR 52.110(d)(1); (4) site-specific decommissioning cost estimate within 2 years following permanent cessation of operations, if not already submitted, in accordance with 10 CFR 50.82(a)(8)(iii) or 10 CFR 52.110(h)(3); and (5) updated site-specific estimate of remaining decommissioning costs contained in the license termination plan, in accordance with 10 CFR 50.82(a)(9)(ii)(F) or 10 CFR 52.110(i)(2)(vi).
