SUBJECT:
ANALYSIS OF NORTHERN STATES POWER COMPANYS UPDATED DECOMMISSIONING FUNDING PLANS FOR THE MONTICELLO AND PRAIRIE ISLAND INDEPENDENT SPENT FUEL STORAGE INSTALLATIONS
By letter dated December 18, 2024 (ML24354A295), Northern States Power Company, a Minnesota corporation, doing business as Xcel Energy (hereafter NSPM) submitted an updated decommissioning funding plan (DFP) for Monticello and Prairie Island Independent Spent Fuel Storage Installations (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 NSPMs 2024 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 NSPM has provided reasonable assurance by which funds will be available to decommission the ISFSI at Monticello and Prairie Island. Therefore, the NRC staff finds that the DCEs adequately estimated the cost, at this time, to carry out required ISFSI decommissioning activities prior to license termination, and that the DCEs are reasonable.
