I l Operational Summary August 1990 i

Reactor power was maintained at approximately 100% until 1335 hours0.0155 days <br />0.371 hours <br />0.00221 weeks <br />5.079675e-4 months <br /> on  !

August 14, 1990, when,the Integrated control System (ICS) ran the plant back i l

to approximately 60% power. The runback to 60% power was due to Main Feed- ')

l vater Pump Turbine (MTPT) 1-1 trip.- The MFPT tripped on lov lube oil pres- 1 sure. The lov lube oil pressure occurred during a maintenance activity on-the ,

MFFT lube oil-cooler. Restoration to 100% power was achieved approximately 44 i hours after the power reduction.

Vith the exception of three power reductions to approximately 93% during the l period from August 26, 1990 to August 31, 1990, reactor power was maintained at approximately 100% pover. The three power reductions. vere due to high 1 condenser pressure resulting from high circulating water-temperature due to the unavailability of 43 circulating vater pump.
