SUMMARY
The reactor was at 100% power for the majority of the month. On October 23, the unit downpowered to approximately 90% to conduct Main Turbine Control Valve, Combined Intermediate Valves Testing. However, on October 24, due to problems identified with the Electric Hydraulic Controls Pump (discharge filter differential pressure high alarm) it was decided to return the plant to 100% power and perform the valve testing at a later time. On October 31, the unit downpowered to approximately 90% for Main Turbine Control Valve, Combined Intermediate Valves Testing.
