SUBJECT:

MILLSTONE POWER STATION, UNIT NO. 3 - REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE (EPID L-2020-LLS-0002)

Dear Mr. Stoddard:

By letter dated November 19, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20324A703), Dominion Energy Nuclear Connecticut, Inc. submitted affidavits dated March 4, 2020, and July 31, 2020, executed by Joanna M. Phillips, on behalf of Cameron Technologies US, LLC (Cameron), requesting that the information contained in the following documents be withheld from public disclosure pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10 CFR):

Cameron Engineering Report ER-369P Rev. 6, Bounding Uncertainty Analysis for the MUR Uprate - Thermal Power Determination at Millstone Unit 3 NPP Using the LEFM+ System Cameron Engineering Report ER-394P Rev. 0, LEFM+ Profile Factor/UVT Discharge Coefficients Calculation and Accuracy Assessment for Millstone Unit 3

A nonproprietary copy of these documents has been placed in the U.S. Nuclear Regulatory Commissions (NRCs) Public Document Room and added to the NRC Library in ADAMS under Accession No. ML20324A703.

The affidavits stated that the submitted information should be considered exempt from mandatory public disclosure for the following reasons:

(a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of Camerons competitors without license from Cameron constitutes a competitive economic advantage over other companies.

(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.

D. Stoddard (c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, and assurance of quality, or licensing a similar product.

We have reviewed your application and the material accordance with the requirements of 10 CFR 2.390 and, on the basis of the statements statements in the affidavits, have determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure.

Therefore, the versions of the submitted documents marked as proprietary will be withheld from public disclosure pursuant to 10 CFR 2.390(b)(5) and Section 103(b) of the Atomic Energy Act of 1954, as amended.

Withholding from public inspection shall not affect the right, if any, of persons properly and directly concerned to inspect the documents. If the need arises, we may send copies of this information to our consultants working in this area. We will, of course, ensure that the consultants have signed the appropriate agreements for handling proprietary information.

If the basis for withholding this information from public inspection should change in the future such that the information could then be made available for public inspection, you should promptly notify the NRC. You also should understand that the NRC may have cause to review this determination in the future, for example, if the scope of a Freedom of Information Act request includes your information. In all review situations, if the NRC makes a determination adverse to the above, you will be notified in advance of any public disclosure.

If you have any questions regarding this matter, I may be reached at 301-415-1030 or Richard.Guzman@nrc.gov.

Sincerely,

/RA/
