Monticello Nuclear Generating Plant Docket 50-263 Renewed Facility Operating License No. DPR-22 On March 28, 2017, Northern States Power Company, a Minnesota corporation (NSPM) d/b/a Xcel Energy submitted biennial decommissioning funding reports for the Monticello Nuclear Generating Plant (MNGP) and Prairie Island Nuclear Generating Plant (PINGP) Units 1 and 2 in accordance with 10 CFR 50.75(f)(1) [ADAMS Accession No. ML17087A246]. As a result of discussions with NRC staff during a public conference call held on December 19, 2017, NSPM has determined that incorrect burial escalation factors had been used in calculating the minimum required decommissioning fund estimate. The attached enclosures provide corrected values for the minimum required decommissioning fund estimate for PINGP and MNGP and supersede Enclosures 1 through 3 of the March 28, 2017, letter.
It should be noted NSPM maintained funding that would meet or exceed the NRC minimum amount required at permanent plant shutdown.
Summary of Commitments This letter makes no new commitments and no revisions to existing commitments.

Basis for Allowance:
Xcel Energy files a triennial decommissioning study with the Minnesota Public Utilities Commission (MPUC) for approval. A portion of the study is dedicated to an analysis of inflation factors surrounding the various components necessary to perform the decommissioning function. Note: These rates apply to external funds only for radiological decommissioning. The rate of earnings and escalation factors were approved by the MPUC in the most recent triennial decommissioning study completed by the company, MPUC Docket No. E002/M-14-761, effective October 5, 2015. The projected real rate of return of 1.88% during operations and 0.99% post-shutdown would accumulate sufficient decommissioning funds by the current 2033 end of license date.
