Summary:

Catawba unit 2 began the month of March operating at approximately 14% power and decreasing to begin end-of-cycle 12 refueling outage. The unit was taken off-line 03/01/03 at 0056 to begin end-of-cycle 12 refueling outage. The end-of-cycle 12 refueling outage spanned 26.22 days. The unit was placed on-line 03/27/03 at 0609. During power escalation, the unit held at 11% power from 03/27/03 at 0622 to 03/27/03 at 0658 due to shift turnover. The unit increased power and held at 19% power from 0757 to 1411 due to main turbine soak. The turbine overspeed trip test was performed 03/27/03 at 0411. The unit was placed on-line 03/27/03 at 1656. The unit held at 19% power from 1751 to 03/28/03 at 1650 due to main feedwater nozzle swap. The unit began decreasing power on 03/28/03 at 1650 and was taken off-line 03/28/03 at 1835 to repair feedwater valve (2CA-42) and turbine intercept valve #2. The unit was placed on-line 03/29/03 at 0538. On 03/29/03 at 0717 the unit held at 19% power until 1154 (Cont'd)

Summary:

due to main feedwater nozzle swap. The unit held at 76% power from 03/30/03 at 0632 to 0840 due to power ascension testing. The unit held at 90% power due to nuclear instrumentation calibration from 1511 to 1640. The unit held at 94% power from 03/30/03 at 1829 to 03/31/03 at 0256 due to process cabinet deltaT channel calibrations.

The unit returned to 100% full power on 03/31/03 at 1037 and operated at or near 100% full power the remainder of the month.

MAIN TURBINE TRIP GENERATED BY HI HI STEAM GENERATOR lB LEVEL Summary:

Catawba unit I began the month of February operating at approximately 100% full power. On 02/04/02 at 1005 a automatic reactor trip was initiated from 100% full power by a main turbine trip generated by Hi Hi steam generator lB level. The unit was placed on-line 02/05/03 at 2311. During power escalation, the unit held at 18% power from 02/06/03 at 0013 to 0103 due to main feedwater nozzle swap. The unit held at 55% power from 0520 to 0550 to place second main feedwater pump in service. The unit held at 87% power from 1044 to 1207 to perform the main turbine control valve movement test. The unit returned to 100% full power on 02/06/03 at 1700 and operated at or near 100% full power the.
