SUBJECT:
ANALYSIS OF THE SACRAMENTO MUNICIPAL UTILITY DISTRICTS UPDATED DECOMMISSIONING FUNDING PLAN FOR THE RANCHO SECO INDEPENDENT SPENT FUEL STORAGE INSTALLATION
By letter dated March 27, 2023 (ML23115A172), the Sacramento Municipal Utility District (SMUD) submitted an updated decommissioning funding plan (DFP) for the Rancho Seco Independent Spent Fuel Storage Installation (ISFSI), for U.S. Nuclear Regulatory Commission (NRC) staff review. Pursuant to Title 10 of the Code of Federal Regulations (CFR) 72.30(c), at the time of license renewal and at intervals not to exceed three years, the initial DFP required to be submitted by 10 CFR 72.30(b) must be resubmitted with adjustments as necessary to account for changes in costs and the extent of contamination in an updated DFP. The updated DFP must update the information submitted with the original or prior approved plan. In addition, the updated DFP must also specifically consider the effect of the following events on decommissioning costs, as required by 10 CFR 72.30(c)(1)-(4): (1) spills of radioactive material producing additional residual radioactivity in onsite subsurface material, (2) facility modifications, (3) changes in authorized possession limits, and (4) actual remediation costs that exceed the previous cost estimate.
The NRC staff reviewed SMUDs 2025 updated DFP, including the updated decommissioning cost estimate (DCE) and the method of assuring funds for decommissioning, in accordance with 10 CFR 72.30(c) and NUREG-1757, Vol. 3, Rev. 1, Consolidated Decommissioning Guidance. Based on the review, the NRC staff finds that the updated DFP contains the information required by 10 CFR 72.30(c) and that SMUD has provided reasonable assurance by which funds will be available to decommission the ISFSI at Rancho Seco. Therefore, the NRC staff finds that the DCE adequately estimated the cost, at this time, to carry out required ISFSI decommissioning activities prior to license termination, and that the DCE is reasonable.
