REQUEST FOR ADDITIONAL INFORMATION REGARDING REQUEST TO WITHHOLD INFORMATION IN FRAMATOME INC.

DOCUMENT ANP-2718P-007 FROM PUBLIC DISCLOSURE ENERGY HARBOR NULEAR CORP.

DOCKET NO. 50-346 By letter dated July 21, 2022 (Agencywide Documents Access and Management System Package Accession No. ML22202A429) Energy Harbor Nuclear Corp. submitted a reanalysis of the protection against low temperature reactor coolant system overpressure events for Davis-Besse Nuclear Power Station, Unit No. 1 (Davis-Besse). The letter included an affidavit (enclosure A) from Framatome Inc. requesting that information provided in ANP-2718P-007, Appendix G Pressure-Temperature Limits for 52 EFPY [Effective Full Power Years] for the Davis-Besse Nuclear Power Station (enclosures B), be withheld from public disclosure in accordance with Title 10 of the Code of Federal Regulations (10 CFR) section 2.390.

The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed the affidavit and the information marked as proprietary in enclosure B. The NRC staff has determined that additional information is needed to for the staff to complete its determination regarding the request for withholding information in enclosure B from public disclosure.

Request for Additional Information The affidavit in enclosure A states, in part, that enclosure B contains information of a proprietary and confidential nature and is of the type customarily held in confidence by Framatome Inc. and not made available to the public.

Page 8-20 of enclosure B indicates that the two paragraph under Development of LTOP [Low Temperature Overpressure Protection] Set Point and table 8-8 are considered to be proprietary by Framatome. However, some of the information in these paragraphs and table 8-8 is not marked as proprietary in other parts of the document and is publicly available in the nonproprietary version of the document (enclosure C). Some of this information is also publicly available in the technical specifications bases and updated final safety analysis report for Davis-Besse (ML20302A348).

Explain why all the information referenced above should be withheld from public disclosure given that some of the information is publicly available in other sources and was provided in the nonproprietary version of the document. The response should address the applicable requirements in 10 CFR 2.390(b)(ii) and (iii).
