NARRATIVE REPORT
-~~~~~~~~~~~
Unit I began the month of June operating at rated thermal power. Shift reduced load to approximately 875 GMWe
(-2748 CMWU) on June 13 after the "A" Reactor Feed Pump Minimum Flow Valve failed partially open. The minimum flow line was isolated and the unit was returned to rated thermal power later that day. Shift reduced load to approximately 820 GMWe (-2540 CMWT) on June 14 to perform control rod drive exercises. The unit was returned to rated thermal power on June 15. Shift reduced load to approximately 890 GMWe (-2705 CMWQ) on June 22 to perform main turbine valve testing. The unit was returned to rated thermal power later that day. Shift reduced load to approximately 805 GMWe (-2430 CMWT) on June 23 when power was momentarily lost to the fans on the Helper Cooling Tower, due to a faulted transformer, and main condenser vacuum began to degrade. The fans cycled back on as designed, and the unit was returned to rated thermal power later the same day. Shift maintained unit operation at rated thermal power for the remainder of the month.

CAUSE/CORRECTIVE ACTIONICOMMENTS:
NARRATIVE REPORT Unit 2 began the month of June operating at rated thermal power. Shift reduced load to approximately 550 GMWe
(-1795 CMWT) on June 13 to perform a control rod sequence exchange, scram time testing, control rod drive exercises, and main turbine valve testing. Inspection and maintenance activities were also performed in the condenser bay while at reduced load. The unit was returned to rated thermal power on June 14. Shift reduced reactor power to approximately 22% of rated thermal on June 21 and removed the main generator from the grid to facilitate the repair of a leak on a filter in the Stator Cooling Water System. Shift re-tied the main generator to the grid on June 21 and returned the unit to rated thermal power on June 22. Shift reduced load to approximately 855 GMWe (-2625 CMWT) on June 23 for a rod pattern adjustment. The unit was returned to rated thermal power later that day. Shift reduced load to approximately 815 GMWe (-2430 CMWT) on June 23 when power was momentarily lost to the fans on the Helper Cooling Tower, due to a faulted transformer, and main condenser vacuum began to degrade. The fans cycled back on as designed, and the unit was returned to rated thermal power later the same day. Shift maintained unit operation at rated thermal power for the remainder of the month.
