g, and other large components that are radioactive to a comparable degree; (2) radiological decontamination and decommissioning—removal of remaining radioactive plant systems, including radiological decontamination; (3) management and support (undistributed costs)—expenses such as labor costs of utility support staff and decommissioning contractor staff, energy costs, regulatory costs, small tools, insurance, and others; (4) waste packaging/shipping—placing waste in packages and shipping to waste vendors or burial site; (5) waste burial or waste vendor—waste burial charges, including waste vendors’ processing fees; and (6) contingency—allowance for unexpected costs. Cost estimates should also include the assumptions, references, and bases for unit costs used in developing the estimates, as well as a description of how the cost estimate accounts for inflation. The cost estimate should be provided in current-year dollars. Escalation of the waste disposition costs is considered separately from the general inflation rate applicable to labor, material, and energy costs. Regulatory Position C.1.2 discusses escalation factors. 1.4 Adjustments to Decommissioning Cost Estimates In order to maintain adequate funds until completion of decommissioning, funding provisions should contain procedures for the periodic review and adjustment of the initial estimate and subsequent amounts set aside, during both operation and any storage periods, based on the factors below. 1.4.1 Inflation The effect of inflation on the estimated decommissioning cost should be determined. For licensees subject to the certification requirements of 10 CFR 50.75(b), the certification amount should be adjusted annually, using the formula in 10 CFR 50.75(c)(2) (see Regulatory Position C.1.2). For licensees using site-specific decommissioning cost estimates (i.e., non-power production or utilization DG-1348 Revision 1, Page 14 facility licensees, power reactor licensees not covered by 10 CFR
