Quad Cities Unit 1 Returned to Service

Quad Cities Unit 1 was placed back in operation at 5:31 p.m. on Saturday.



Cordova, Illinois - Quad Cities Unit 1 was placed back in operation at 5:31 p.m. on Saturday.  The unit was taken offline on Thursday, Aug. 12, to make repairs to valves associated with the plant's main condenser. The main condenser turns the steam generated in the reactor back into reusable water as part of the plant's normal operation.

"In addition to the condenser work, we completed other preventive maintenance activities while the unit was offline," said Randy Gideon, Site Vice President. "The unit had been in continuous operation over 330 days prior to coming offline. With the work completed during this shutdown, the plant is well positioned for continued safe and reliable operation until the next scheduled refueling outage in 2011."

Quad Cities Unit 2 continues to operate at full power and there was no impact to the Exelon customers as a result of Unit 1 being offline.

Quad Cities Generating Station is located on the banks of the Mississippi River in Cordova, Ill. With both units running at full power, Quad Cities generates electricity to power more than 1 million average American homes.
