Dominion Nucar Connecticut, Inc.u 5000 Dominion Boulevard, Glen Allen, Virginia 23060 Web Address: www.dom.com Withhold Attachment 7 from Public Disclosure Under 2.390(a)(4)

July 13, 2007 U. S. Nuclear Regulatory Commission Serial No.: 07-0450 Attention: Document Control Desk NLOS/MAE: RO One White Flint North Docket No.: 50-423 11555 Rockville Pike License No.: NPF-49 Rockville, MD 20852-2378 DOMINION NUCLEAR CONNECTICUT. INC.

MILLSTONE POWER STATION UNIT 3 LICENSE AMENDMENT REQUEST STRETCH POWER UPRATE Pursuant to 10 CFR 50.90, Dominion Nuclear Connecticut, Inc. (DNC) hereby requests an amendment to Operating License NPF-49 for Millstone Power Station Unit 3 (MPS3). This proposed Stretch Power Uprate (SPU) License Amendment Request (LAR) would increase the unit's authorized core power level from 3411 megawatts thermal (MWt) to 3650 MWt, and make changes to Technical Specifications as necessary to support operation at the stretch power level.

DNC developed this LAR utilizing the guidelines in NRC Review Standard, RS-001, "Review Standard for Extended Power Uprates." In addition, requests for additional information (RAIs) regarding SPU and Extended Power Uprate (EPU) applications for other nuclear units were reviewed for applicability. Information that addresses many of those RAIls is included in this MPS3 SPU LAR.

RS-001 states that a SPU is characterized by power level increases up to 7 percent and does not generally involve major modifications. Plant modifications are addressed in Section 1.0 of the License Report (LR) (Attachment 5) and are not considered to be major. Since the requested uprate is 7 percent and does not involve major plant modifications, it is considered to be a SPU.

Information provided in the Attachments to this letter are summarized as follows:

Attachment 1 provides Description, Technical Analysis and Regulatory Analysis for the proposed Operating License and Technical Specifications changes. Also provided is a description of the License Basis Changes that require NRC review and approval as part of the SPU. As discussed in this attachment, the proposed amendment does not involve a significant hazards consideration pursuant to the provisions of 10 CFR 50.92. The Site Operations Review Committee has reviewed and concurred with this determination.

This LR demonstrates acceptable facility operation at the increased power level.
