SUBJECT:

REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE

- MILLSTONE POWER STATION, UNI T NO. 3, PROPOSED ALTERNATIVE REQUEST IR-4-13 TO SUPPORT STEAM GENERATOR CHANNEL HEAD DRAIN MODIFICATION (EPID L-2024-LLR-0025)

Dear Eric Carr:

By letter dated April 1, 2024 (Proprietary, N on-Public), Dominion Energy Nuclear Connecticut, Inc., submitted an affidavit dated March 15, 2024, executed by Zachary Harper, Senior Manager, Licensing for Westinghouse Electric Company, LLC, requesting that the identified information contained in the following document be withheld from public disclosure pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10 CFR):

Enclosure 2 titled LTR-CECO-24-001-P, Revision 0, Westinghouse Technical Summary (Proprietary)

A nonproprietary copy of this document has been placed in the U.S. Nuclear Regulatory Commissions (NRCs) Public Document Room and added to the NRC Library in the Agencywide Documents Access and Managem ent System Accession No. ML24093A102).

The affidavit stated that the submitted infor mation 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 Westinghouses competitors without license from West inghouse constitutes a competitive economic advantage over other companies.

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

(e) It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.

E. Carr

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

Therefore, the version of the submitted information 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, the NRC staff may send copies of this information to our consultants working in this area. The NRC 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 revi ew 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 by email to Richard.Guzman@nrc.gov.

Sincerely,

/RA/

Richard V. Guzman, Senior Project Manager Plant Licensing Branch I Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation
