SUBJECT:
H.B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 - REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE REGARDING THE SUBSEQUENT LICENSE RENEWAL APPLICATION (EPID NO. L-2025-SLR-0000)
Dear Laura Basta:
By letter dated April 1, 2025 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML25091A290), you submitted four affidavits dated June 11, 2024, November 25, 2024, December 9, 2024, and February 28, 2025, executed by Camille Zozula, Jerrod Ewing, and Zachary Harper for Westinghouse Electric Company (Westinghouse), and you requested 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):
Westinghouse WCAP-15628-P, Revision 1, Technical Justification for Eliminating Large Primary Loop Pipe Rupture as the Structural Design Basis for the H.B.
Robinson Unit 2 Nuclear Power Plant for the Subsequent License Renewal Program, affidavit executed by Camille Zozula on June 11, 2024 Westinghouse WCAP-18900-P, Revision 0, Flaw Tolerance Evaluation for Susceptible Reactor Coolant Loop Cast Austenitic Stainless Steel Piping Components for H.B. Robinson Unit 2, affidavit executed by Jerrod Ewing on November 25, 2024 Westinghouse WCAP-18939-P, Revision 1, H.B. Robinson Unit 2 Subsequent License Renewal: Fracture Mechanics Assessment of Reactor Pressure Vessel Structural Steel Supports, affidavit executed by Zachary Harper on December 9, 2024 Westinghouse WCAP-18944-P, Revision 0, H.B. Robinson Unit 2 Subsequent License Renewal: Reactor Vessel Upper Shelf Energy Equivalent Margins Analysis, affidavit executed by Zachary Harper on February 28, 2025 April 28, 2025
L. Basta Nonproprietary copies of these documents have been added to the U.S. Nuclear Regulatory (NRC) Library in ADAMS (Package Accession No. ML25091A290).
The affidavits stated that the submitted information should be considered exempt from mandatory public disclosure for the following reasons:
Camille Zozula - Westinghouse WCAP-15628-P (4)
Pursuant to 10 CFR 2.390, the following is furnished for consideration by the Commission 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)
Westinghouse notes that a showing of substantial harm is no longer an applicable criterion for analyzing whether a document should be withheld from public disclosure. Nevertheless, public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of 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.

The NRC staff has reviewed your application and the material in accordance with the requirements of 10 CFR 2.390 and based on 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 versions 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. The NRC staff 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.
L. Basta If you have any questions regarding this matter, please contact me at Andrew.Siwy@nrc.gov.
Sincerely, Andrew D. Siwy, Senior Project Manager License Renewal Projects Branch Division of New and Renewed Licenses Office of Nuclear Reactor Regulation Docket No. 50-261:
