1 END-OF-CYCLE 20 REFUELING OUTAGE Summary:

Oconee unit 3 began the month of April operating at approximately 97.72% power coasting down to end-of-cycle 20 refueling outage. On 04/25/03 at 2303 the unit ended the coastdown and began decreasing power to end-of-cycle 20 refueling outage. The unit held at 15% power from 04/26/03 at 0141 to 0158 when the unit was taken off-line on 04/26/03 at 0158 to begin end-of-cycle 20 refueling outage. The unit remained in the end-of-cycle 20 refueling outage the remainder of the month
