Oconee unit 2 began the month of November, 2003 in end-of-cycle 19 refueling outage. The refueling outage was delayed 11.24 days due to reactor vessel head control rod drive penetration repairs. The unit was placed on-line 11/23/01 at 0544 holding at approximately 16% power. The turbine overspeed trip test was performed 11/23/02 at 1000. The unit was placed on-line 11/23/02 at 1222. During power escalation, the unit held at 33% power from 11/23/02 at 1340 to 1417 due to (2HPE-10) high pressure extraction valve repairs.

The unit held at 41% power from 1526 to 2051 due to main turbine bearing vibration analysis. On 11/24/02 the unit held at 70% power from 0253 to 0501 due nuclear instrumentation calibration. The unit held at 73% power from 0542 to 1528 due to power imbalance detector correlation test. On 11/24/02 the unit held at 93.2% power from 2101 to 11/25/02 at 0121 due to nuclear instrumentation calibration. The unit returned to 100% full power on 11/25/02 at 0347 and operated at or (Cont'd)

Oconee unit 3 began the month of November operating at or near 100% full power. On 11/14/02 at 0420 an automatic reactor trip occurred due to high moisture separator reheater level. The unit was placed on-line 11/17/02 at 0422. During power escalation, the unit held at 88% power from 1120 to 1352 due to nuclear instrumentation calibration check.

The unit held at 91% power from 11/17/02 at 1406 to 1502 to evaluate the need to perform turbine valve movement test. The unit held at 99.5% power from 1657 to 11/18/02 to 1655 to start 3E1 and 3E2 heater drain pumps. The unit returned to 100% full power on 11/18/02 at 1700 and operated at or near 100% full power the remainder of the month.
