[anergy. Self Assessment

• Self Assessment completed this summer to identify additional design basis focus areas

• Independent consultant was used to validate the scope of the assessment and review completed work

• Conclusion of independent review is that significant progress has been made in improving Oconee's design basis

• Recommendations from the assessment have been reviewed and prioritized by the Oconee Design Review Board 18

I Duke UEnergy. Future Focus Areas

"* Oconee's self assessment identified the following areas for additional review/initiatives

- Seismic risk

- SSF Reliability

- Appendix R

- Turbine Building flooding

- External flooding

- Containment isolation

- Spent Fuel Pool cooling

"* Lower level issues identified through the assessment are being resolved through the corrective action program 19
