Dresden Unit 2 Returned to Service

MORRIS, Ill. — Operators at Exelon’s Dresden Generating Station returned Unit 2 to full power at approximately 3 a.m. CT today following the completion of maintenance on the unit’s condenser.
The condenser converts leftover steam used to spin the turbine back into water. The water is reused to make more steam to power the turbine.
Station personnel worked on water tubes located inside the condenser and performed other maintenance activities that could not be done while the unit was operating. Unit 2 was taken offline on Thursday, Aug. 30. It was placed back in service on Wednesday, Sept. 5.
Dresden Generating Station is approximately 60 miles southwest of Chicago. The station’s two operating units can produce more than 1,700 megawatts, enough electricity to power nearly 2 million average homes. Dresden Unit 1, which began commercial operation in 1960 and was retired in 1978, has been designated a Nuclear Historic Landmark by the American Nuclear Society.
