SUBJECT:

REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE FOR VIRGIL C. SUMMER NUCLEAR STATION, UNIT NO. 1, REQUEST FOR WITHHOLDING, APPLICATION FOR ALTERNATIVE REQUEST - EXTENSION OF STEAM GENERATOR PRIMARY INLET NOZZLE DISSIMILAR WELD INSPECTION INTERVAL (EPID: L-2022-LLR-0033)

Dear Mr. Stoddard:

By letter dated March 10, 2022 (Agency Documents Access Management System (ADAMS)

Accession No. ML22069B117), you submitted an affidavit dated October 13, 2021, executed by Anthony J. Schoedel, Manager, eVinci Licensing & Configuration Management 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):

LTR-SDA-21-023-P, Revision 0, V.C. Summer Unit 1 Steam Generator Hot Leg Inlet Nozzle to Safe-End Weld PWSCC Growth Analysis 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 ADAMS.

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

(4) Pursuant to 10 CFR 2.390, the following is furnished for consideration in determining whether the information sought to be withheld from public disclosure should be withheld.

(i) The Information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse and is not customarily disclosed to the public.

(ii) The information sought to be withheld is being transmitted to the Commission in confidence and, to Westinghouses knowledge, is not available in public sources (iii) public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of

D. Stoddard Westinghouse because it would enhance the ability of competitors to provide similar technical evaluation justifications and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.

(5) Westinghouse has policies in place to identify proprietary information.

Under that system information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows:

(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 Westinghouse 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.

We have 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(s) 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, 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.

D. Stoddard If you have any questions, please contact me at (301) 415-2481, or via email at ed.miller@nrc.gov.

Sincerely,

/RA/
