UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 November 29, 2017 Mr. Thomas D. Ray Vice President Oconee Nuclear Station Duke Energy Carolinas, LLC 7800 Rochester Highway Seneca, SC 29672-0752

SUBJECT:

OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 - REQUEST FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE RE: OCONEE THERMAL-HYDRAULIC MODELS FOR STANDBY SHUTDOWN FACILITY TRANSIENT ANALYSIS (EPID L-2017-LLA-0365)

Dear Mr. Ray:

By letter ONS-2017-074 dated October 20, 2017 (Agencywide Documents Access and Management System Accession No. ML17299A125), Duke Energy Carolinas, LLC (the licensee) submitted an affidavit dated October 9, 2017, which was executed by Mr. Joseph Donahue of the licensee's staff, requesting that the information contained in the following document be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (1 O CFR), Part 2, Section 2.390 for Oconee Nuclear Station, Units 1, 2, and 3:

Attachment 2 - Thermal-Hydraulic Models for SSF [Safe Shutdown Facility]

Transient Analysis [Proprietary].

A non-proprietary version of the above document is available in Attachment 3 of the licensee's letter dated October 20, 2017.

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

4(vi) The proprietary information has substantial commercial value to Duke Energy; (a) Duke uses this information to reduce vendor and consultant expenses associated with supporting the operation and licensing of nuclear power plants; (b) Duke can sell the information to nuclear utilities, vendors, and consultants for the purpose of supporting the operation and licensing of nuclear power plants; and (c) The subject information could only be duplicated by competitors at similar expense that incurred by Duke.

T. Ray The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed the submittal in accordance with the requirements of 10 CFR 2.390 and, based on the statements in the affidavit, has determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure. Therefore, the aforementioned document 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 may send copies of this information to its consultants. The NRC will ensure that its 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, the licensee should promptly notify the licensee. The NRC may revisit this determination in the future if, for example, the scope of a Freedom of Information Act request includes this information. The NRC will notify the licensee in advance of any public disclosure if the NRC makes such a determination.

Any questions regarding this matter can be directed to me at 301-415-0489 or Audrey. Klett@nrc.gov.

Sincerely, Audrey Klett, Project Manager Plant Licensing Branch 11-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-269, 50-270, and 50-287 cc: Joseph Donahue Vice President Duke Energy Corporation 7800 Rochester Highway Seneca, SC 29672-0752 Additional Distribution via Listserv
