SUMMARY

January 1994 " j Reactor power was maintained at approximately 100 percent ' full power until 0137 hours0.00159 days <br />0.0381 hours <br />2.265212e-4 weeks <br />5.21285e-5 months <br /> on January 16, 1994, when a manual. power reduction to approximately 94 percent power was initiated to perform main turbine control valve testing and control rod drive (CRD) exercise testing.

After completion of main turbine control valve testing and CRD exercise.

testing, reactor power was slowly increased to apprcximately 100 percent full power, which was achieved at 0415 hours0.0048 days <br />0.115 hours <br />6.861772e-4 weeks <br />1.579075e-4 months <br /> on.
