SUMMARY
- Columbia Generating Station began and ended the month at 100% power. On September 5, 2004 power was reduced to about 73% to repair an oil leak on COND-F-3B. Full power was resumed on the afternoon of September 5, 2004. On August 15th the reactor was manually scrammed in response to a feedwater pump trip. The cause was a combination of reduced hotwell level controller response (adjusted to the high tend of the control band) and the shutdown water management condition (higher than normal water inventory in the Condensate Storage and Transfer system). High water level in the main condenser hotwell overflowed to cause a high water level in the feedwater drive turbine condenser drain tank and resulted in a trip signal to the feedwater pumps.
