PART A OPERATIONS SUEARY l

The plant operated at approximately 100% power with the following exceptions:

1) On 5/2/88, a reactor trip on 'B' steam generator low-low level occurred as a result of turbine control valves stroking closed due to a faulty signal from the throttle pressure limiter circuitry. Power operations resumed 5/3/88.

j

2) On 5/10/88, a turbine runback to 67% power occurred when the 'B' circulating water pump tripped during an undervoltage relay replacement.

3) On 5/23/88, a turbine runback to 74% power occurred when the

'C' circulating water pump tripped due to a phase imbalance relay problem.

4) on 5/31/88, a turbine runback to 75% power occurred when the

'B' circulating water pump tripped due to a phase imbalance relay problem.

Returns to full power were initiated approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> af ter each of the three runbacks.
