Generating Station for the Inonth of August,1989. 'Ihis turu.t is being provided pursuant to Technical Specification 6.9.1.8.

I. St395ARY CF OPERATDG EKPERIENCE The unit operated at 100% power until August 09, 1989, at 1920 hours0.0222 days <br />0.533 hours <br />0.00317 weeks <br />7.3056e-4 months <br /> when Reactor power es lowered to 95% to repair a nanway leak on the 4B Irw Pressure Feechster Heater. At 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, August 10, 1989, Reactor power was at 99% with work cantinuing an the nanway leak. At 1054 hours0.0122 days <br />0.293 hours <br />0.00174 weeks <br />4.01047e-4 months <br /> the Iow Pressure Feedwater Heater 4B was returned to service and Reactor power to 100%. At 1723 hours0.0199 days <br />0.479 hours <br />0.00285 weeks <br />6.556015e-4 months <br /> Reactor power was again rwhvwi to 95% to repair a level switch on High Pressure Heater 7B. On August 11,1989, at 0300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> the 7B High Pressure Feedwater Heater was returned to service and Reactor power returned to 100%. The unit r-4=rl at 100% power for the renainder of the nanth.
