SUMMARY

JANUARY, 1992 UNIT ONE 1

Unit Ono began the month operating at full power. On the third at 10:00 hours, the unit load was decreanod to 60% to repair a tube leak in the E8A Feedwater lleater. As the unit returned to full power, the scheduled monthly turbino valvo surveillance was performed, starting at 21:46 hours.

During the turbine valvo surveillance, at 22:25 hours..the plant lohd was decreased to 65% power to stabilize oscillations in the 1B Hain Feodwater pump. by 04:45 hourn on tha foutth, the unit. het returned to 91% power to allow completion of the turbine valve surveillance. During the ramp back to full power, after completion of the turbino valvo test (at 05:04 hours),

the plant experienced another erratic control cond4. tion on the 1B Hain Feedwater Pump. The plant reduced power to 85% to stabilize the pump. At 16:55 hours on the same day, power was incrnamed and the unit reached full power at 0'0:48 hours on the fifth. At 13:28 hours on the fifth, power was decreased to 90% to investigato the control oscillations on the 1B Hain Feedwater Pump. The unit was returned to full power at 16:05 hours on the same day. On the seventeenth at 08:40 hours, power was reduced to 98% to allow operation with only two Circulating Water Pumps due to a fish run at the intake screenhouse. This condition ended at 09:55 hours on the same day. Power was reduced to 95% on the twentieth at 08: 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> to again allow operation with only two Circulating Water pumps due to a fish run.

The unit-returned to full power on the same day at 12:15 hours. On the twenty-third at 14:05 hours, power.was reduced to 98% to allow the isolation of a waterbox due to indication of a condenser tubo leak. The unit was returned to full power at 19:00 hours on the same day. The unit

- operated at full power for the; remainder of January, i-
