Pursuant to 10 CFR 50.90, the Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, requested in Reference 1 an amendment to the Monticello Nuclear Generating Plant (MNGP) Renewed Operating License (OL) and Technical Specifications (TS) to increase the maximum authorized power level from 1775 megawatts thermal (MWt) to 2004 MWt.

In References 2 and 3, NSPM modified the No Significant Hazards Consideration (NSHC) and updated certain topics associated with the MNGP Extended Power Uprate (EPU) project.

Document Control Desk Page 2 On November 20, 2012, NSPM presented to the NRC the results of a Gap Analysis performed to verify the adequacy of the EPU documentation. Due to the delay in review of the MNGP EPU License Amendment Request (LAR), the NRC was concerned that various aspects of the NRC review were no longer applicable. Through the Gap Analysis review NSPM demonstrated that a small set of technical issues required revision and some design and licensing bases information had changed, but overall the body of EPU documentation was correct with the exception of the issues identified for correction.

The purpose of this letter is to provide the NRC with revisions to the EPU documentation based on the results of the GAP Analysis. provides responses to 28 items from the Gap Analysis. Enclosure 2 provides marked up pages to portions of the EPU documentation based on the discussion provided in Enclosure 1. Note that two items concerning 10 CFR 50, Appendix R issues from the Gap Analysis were previously provided to the NRC in a letter dated November 30, 2012 (ADAMS Accession No. ML123380435). Other Gap Analysis responses will be provided at a later date. Enclosure 3 provides additional supplemental materials as referenced by Enclosure 1.

The changes made herein do not revise the NSHC provided in Reference 1 as revised by References 2 and 3.

In accordance with 10 CFR 50.91(b), a copy of this application supplement, without enclosures, is being provided to the designated Minnesota Official.

Summary of Commitments This letter makes no new commitments and no revisions to existing commitments.

Document Control Desk Page 3 I declare under penalty of perjury that the foregoing is true and correct.
