SUMMARY

January 1995 On January 1,1995 at 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />, a manual power reduction was initiated from approximately 100 percent full power to perform control valve testing, combined intercept valve testing, and control rod drive exercising. Power was manually reduced to approximately 93 percent full power by 0147 hours0.0017 days <br />0.0408 hours <br />2.430556e-4 weeks <br />5.59335e-5 months <br />, and valve testing and control rod drive exercising was performed. -

Reactor power was reduced to approximately 91 percent as a result of control rod drive exercising, and at the request of the Load Dispatcher, this power level was maintained when exercising was complete. At 0540 hours0.00625 days <br />0.15 hours <br />8.928571e-4 weeks <br />2.0547e-4 months <br />, reactor power was gradually increased to approximately 100 percent full power, which was achieved at 0710 hours0.00822 days <br />0.197 hours <br />0.00117 weeks <br />2.70155e-4 months <br />.

Reactor power was maintained at this level until January 29,1995, when at 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, a manual power reduction was initiated to perform control valve testing, combined intercept valve testing, and control rod drive exercising.

Power was manually reduced to approximately 93 percent full power by 0039 hours4.513889e-4 days <br />0.0108 hours <br />6.448413e-5 weeks <br />1.48395e-5 months <br />, and valve testing and control rod drive exercising was performed.
