3 12/01/01 5 313.58 C 4 END-OF-CYCLE 19 REFUELING OUTAGE OUTAGE DELAY OF 5.01 DAYS DUE TO REACTOR VESSEL HEAD 12/09/01 F120.33 A NOZZLE REPAIRS Summary:

The unit began the month of December, 2001 in end-of-cycle 19 refueling outage. The refueling outage was delayed 5.01 days due to reactor vessel head nozzle repairs.

The end-of-cycle 19 refueling outage spanned 34.01 days. The unit was placed on-line 12/14/01 at 0135 holding at approximately 17% power. The unit held at 28% power from 0253 to 0850 and at 57% power from 12/14/01 at 1301 to 1451 due to nuclear instrumentation calibration. The unit held at 71.4% power from 1736 to 1757 due to high main turbine vibration on bearing #1. On 12/14/01 from 1821 to 12/15/01 at 0407 the unit held at 73% power due to power escalation testing. The unit held at 90% power from 12/15/01 at 0731 to 12/15/01 at 1109 due to nuclear instrumentation calibration. The unit returned to 100% full power on 12/15/01 at 1429 and operated at or near 100% full power the remainder of the month.
