i PART A OPERATIONS StW.ARY f

j The plant operated at approximately 100% power (3411 MWt) untti 4/8/88 when the plant uprated to 3565 HWt. On 4/11/t8, power was reduced to 94% due to a feedvater heater tube leak. The plant was shutdown on 4/16/88 to repair the tube leak. During this shutdown a turbine trip occurred on Hi Hi level in f

l steam generator 'C'.

On 4/17/88, a turbine / reactor trip occurred due to steam generator level oscillations during plant startup. Pwer operations resumed on 4/18/88. On 4/21/88, the plant incurred a manual reactor trip due to a failure of AE-FCV 0530, the 'C' steam generator feedvater regulation valve. A subsequent cooldown to mode 5 was performed to repair a leaking conoseal. Power cperations resumed 4/30/88 I
