'Ibe unit began the month at 100% power (860 MWe).

On 05/13/95 at 1305 power was reduced to 98% due to level fluctuations in the first stage of 12 Moisture -

Separator Reheater (MSR). 'Ihe first and second stage reheaters were renoved from service, due to concerns that the fluctuations could cause tube damage due to thermal fatigue. An evaluation was performed and the MSR second stage was returned to service. The MSR first stage was returned to service at a reduced pressure after determining the pressure where the fluctuations occurred. Power was returned

. to 100% (840 MWe) at 2135 on 05/19/95.

The unit ended the month at 100% power (840 MWe).

The unit began the month in mode 5, cold shutdown, while completing the scheduled refueling outage.

! - The refueling outage ended on 05/17/95 when the unit was paralleled to the grid at i 151. ,

i 1

%e unit was removed from the grid at 2135 for Main Turbine overspeed testing.~ After completion of the l j ~ Mair. Turbine testing the unit was paralleled to the grid at 0029 on 05/18/95.

s .

On ON24/95 the unit was manually tripped from 97% power at 1249 due to a partial loss of circulatmg -

1

. water flow. Five of the circulating water pumps tripped when a loose metal panel fell onto energized  ;

buswork during the planning of maintenance work. He panel was repaired, electrical inspections  ;
