UNIT SHUTDOWNS Docket No.: 50-366 Unit Name: E. I. Hatch Unit 2 Date: February 1, 2002 Completed By: R. M. Beard Telephone: (912) 367-7781 x2878 Reporting Period: JANUARY 2002 Type Method of F: Forced Duration Shutting Cause/Corrective Actions No. Date S: Scheduled (Hours) Reason (1) Down (2) Comments01-003 011225 F 215.2 A 4 Activities associated with the December 2001 forced outage continued. The outage resulted from failure of the "B" Outboard Main Steam Isolation Valve (LER 2-01-003) and was extended to repair the "B" 4th Stage Feedwater Heater Bypass Valve.

Repairs were made to both valves and the unit was returned to power operation.

CAUSE/CORRECTIVE ACTION/COMMENTS:

NARRATIVE REPORT Unit 2 began the month of January in a forced outage, (see description of event 01-003 above for details).

Shift began withdrawing control rods for unit startup and brought the reactor critical on 1/9/02. Shift tied the main generator to the grid and began power ascension to rated thermal power later on 1/9/02. The unit attained rated thermal power on 1/11/02. Shift reduced load to approximately 715 GMWe (-2170 CMWT) later that day to perform a rod pattern adjustment. The unit was returned to rated thermal power on 1/12/02.

Shift reduced load to approximately 830 GMWe (-2500 CMWT) on 1/28/02 to remove the "B" Condensate Booster Pump from service to repair an oil leak on the pump motor. Shift increased unit load to approximately 895 GMWe (-2680 CMWT) later on 1/28/02 and continued operation at that power level while repairs were being made on the "B" Condensate Booster Pump. Shift returned the "B" Condensate Booster Pump to service on 1/29/02 and ascended to rated thermal power the same day. Shift maintained unit operation at rated thermal power for the remainder of the month.
