J Operational Summary i

October 1992 i

Reactor power was maintained at approximately 100 percent full power until 0202 hours0.00234 days <br />0.0561 hours <br />3.339947e-4 weeks <br />7.6861e-5 months <br /> on October 11, 1992, when a manual power reduction to approximately 96 percent of full power was initiated to perform turbine valve testing and control rod drive exercise testing.

After completion of turbine valve testing, reactor power was slowly decreased to approximately 93 percent of full power due to lov system demand as requested by the Systems Operation Center.
