Background:

Duke Energy

• As we plan to meet our customers future energy needs and continue to reduce our carbon footprint, we are seeking to renew the licenses of the 11 nuclear units we operate at six plant sites in the Carolinas.

• This provides the option to operate these plants for an additional 20 years.

• Relicensing our nuclear fleet is critical to meet Duke Energys goal of net-zero carbon emissions by 2050.

• We expect to submit the license renewal application for Oconee Nuclear Station in March 2021.

Discussion Items

• Methodology Regulatory Standard Practices NUREG 1437, Rev. 1, GEIS, Incorporate by Reference

• SAMA All SAMAs were screened out either qualitatively or quantitatively in accordance with the NEI 17-04, Rev 1 methodology. Therefore, the Stage 2 NEI 17-04 was not required, and the Level 3 PRA was not updated.

The analysis concluded that there is no new and significant information that would alter the conclusions of the original SAMA analysis for ONS.
