No Outages for the Month Summary:

The unit began the month of May operating at approximately 21% power at midnight and increasing power. The unit held at 26.6% power from 05/01/02 at 0013 to 0125 due to hotwell pump discharge pressure. The unit resumed power escalation, and held at 40% power from 0200 to 0227 due to power escalation testing. Problems with 1B feedwater pump turbine motor speed resulted in a hold at 59.2% power from 0630 to 2259. On 05/02/02 from 0153 to 0804 the unit held at 73% power to perform the power imbalance detector correlation test. The unit held at 90% power on 05/02/02 from 1120 to 1125 due to nuclear instrumentation calibration check. The unit returned to 100% full power on 05/02/02 at 1525 and operated at or near 100% full power the remainder of the month.
