Ladies and Gentlemen:

By letter dated June 7, 2021 (Reference 1), Duke Energy Carolinas, LLC (Duke Energy) submitted an application for the subsequent license renewal of Renewed Facility Operating License Numbers DPR-38, DPR-47, and DPR-55 for the Oconee Nuclear Station (ONS), Units 1, 2, and 3 to the U.S. Nuclear Regulatory Commission (NRC). On July 22, 2021 (Reference 2), the NRC determined that ONS subsequent license renewal application (SLRA) was acceptable and sufficient for docketing.

10 CFR 54.21(b) requires Duke Energy to report changes to the Current Licensing Basis (CLB) that materially affect the contents of the SLRA, including the UFSAR supplement. These changes are required to be submitted each year and at least 3 months prior to the scheduled completion of NRC review of the SLRA.

The first annual review results were provided by letter dated June 7, 2022 [ADAMS Accession Number ML22158A028] (Reference 3). The second annual review covers the period since the first annual update. Duke Energy has completed the second annual review of CLB changes to determine whether any sections of the SLRA for ONS were affected by these changes. No material changes were identified during the review that would materially affect the contents of the ONS SLRA.
