05/01/02 5 410.38 C 4 END-OF-CYCLE 13 REFUELING OUTAGE 2 05/18/02 5 2.95 B MAIN TURBINE OVERSPEED TRIP TEST Summary:

The unit began the month of May in end-of-cycle 13 refueling outage. The end-of-cycle 13 refueling outage spanned 21.07 days. The unit was placed on-line 05/18/02 at 0223.

The unit held at 18% power from 0510 to 0919 for required soaking for main turbine overspeed trip testing and then decreased power and held at 10% power from 1001 to 1050 to perform the turbine overspeed trip test. The main turbine overspeed trip test occurred on 05/18/02 at 1050.The unit was placed on-line 05/18/02 at 1347. During power escalation the unit held at 40% power from 1803 to 1859 to assess power ascension ramp rate restrictions. The unit held at 51% power from 2346 to 05/19/02 at 0215 and at 95%

power from 05/19/02 at 2219 to 05/20/02 at 0104 due to power ascension testing. The unit held at 98% power from 0328 to 1017 to evaluate indicated high delta T in excess of 100%.

The unit returned to 100% full power on 05/20/02 at 1100 and operated at or near 100% full power the remainder of the month.
