SUBJECT:

CALLAWAY PLANT, UNIT NO. 1 - REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE (EPID L-2022-LLA-0150 AND EPID L-2022-LLE-0030)

Dear Mr. Diya,

By letter dated October 12, 2022 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML22285A115), you submitted four affidavits, each dated October 7, 2022, executed by Morris Byram, Product Manager, Licensing and Regulatory Affairs for Framatome Inc. (Framatome), which requested that the information contained in the following documents (attachments 9, 10, 11, and 12 to enclosure 1 of the letter dated October 12, 2022) be withheld from public disclosure pursuant to Section 2.390 of Title 10 of the Code of Federal Regulations (10CFR):

[Attachment 9] ANP-3947P, Callaway Unit 1 License Amendment Request Inputs for Use of Framatome Fuel, Revision 3

[Attachment 10] ANP-3944P, Callaway Realistic Large Break LOCA [Loss-of-Coolant Accident] Analysis with GAIA Fuel Design, Revision 1

[Attachment 11] ANP-3943P, Callaway Small Break LOCA Analysis with GAIA Fuel Design, Revision 1

[Attachment 12] ANP-3969P, Callaway Non-LOCA Summary Report, Revision 2 Nonproprietary versions of these documents, contained in attachments 5, 6, 7, and 8 to enclosure 1 of the letter dated October 12, 2022, have been placed in the U.S. Nuclear Regulatory Commissions (NRC) Public Document Room and added to the NRC Library in ADAMS under Accession Nos. ML22285A122, ML22285A123, ML22285A124, and ML22285A125, respectively.

Additionally, by letter dated December 1, 2022 (Package ML22335A497), you submitted an affidavit dated November 16, 2022, executed by Morris Byram, Product Manager, Licensing and

Regulatory Affairs for Framatome, which requested that the information contained in the following document (enclosure 4 to the letter dated December 1, 2022) be withheld from public disclosure pursuant to 10 CFR 2.390.

ANP-4012P, Callaway Rod Ejection Accident Analysis, Revision 1 A nonproprietary version of this document, contained in enclosure 3 of the letter dated December 1, 2022, has been placed in the NRC Public Document Room and added to the NRC Library in ADAMS under Accession No. ML22335A501.

The Framatome affidavits dated October 7, 2022, and November 16, 2022, stated, in part, that the information should be considered exempt from mandatory public disclosure for the following reasons.

(6)

The following criteria are customarily applied by Framatome to determine whether information should be classified as proprietary:

(c)

The information includes test data or analytical techniques concerning a process, methodology, or component, the application of which results in a competitive advantage for Framatome.

(d)

The information reveals certain distinguishing aspects of a process, methodology, or component, the exclusive use of which provides a competitive advantage for Framatome in product optimization or marketability.

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 affidavits, have determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure.

Therefore, attachments 9, 10, 11, and 12 to enclosure 1 of the letter dated October 1, 2022, and enclosure 4 of the letter dated December 1, 2022, marked as proprietary, will be held 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 these determinations 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 301-415-8371 or by email to Mahesh.Chawla@nrc.gov.

Sincerely,

/RA/
