McGuire unit 2 began the month of April, 2005 in end-of-cycle 16 refueling outage. The refueling outage was delayed 1.71 days to repair turbine auxiliary feedwater pump.

During the refueling outage we had problems with the spent fuel up-ender and repaired hotleg decay heat 2ND15B isolation valve. The refueling outage from breaker to breaker spanned 43.45 days. The unit was placed on-line 04/14/05 at 0337 holding at 16% power for the turbine soak and to perform the turbine overspeed trip test. The unit was taken off-line 04/14/05 at 1036 to perform the turbine overspeed trip test. The unit was placed on-line at 1211 holding at approximately 16% power until 04/15/05 at 0302.

The unit was taken off-line 04/15/05 at 0302 to investigate/inspect/repair steam generator "A" feedwater regulator valve 2CF-32. The unit returned to service on 04/17/05 at 0709.

The unit began increasing power to place 2A feedwater pump in auto to allow engineering to tune feedwater pumps. At 1231 the unit began decreasing power due to 2A steam generator feedwater regulator valve 2CF-32 problem and was taken off-line 04/17/05 at 2309 to investigate/repair valve. The unit was placed on-line 04/21/05 (Cont'd)

Summary:

at 0007. During power escalation, the unit held at 29% power on 04/21/05 from 0528 to 0915 due to secondary chemistry. The unit held at 40% power from 1124 to 1220 to start 2CI and 2C2 heater drain tank pump. On 04/21/05 from 1341 to 1634 the unit held at 43% power to place 2B feedwater pump in-service. The unit held at 78% power on 04/22/05 from 0635 to 1249 due to flux mapping. The unit held at 95% power on 04/22/05 from 1957 to 04/23/05 at 1043 for delta-T and thermal power test. On 04/24/05 at 0300 the unit returned to 100% full power and operated at or near 100% full power the remainder of the month.
