Clinton nuclear plant taken offline for repairs

Exelon (NYSE:EXC) confirmed Jan. 23 that its Clinton nuclear plant in Illinois has temporarily been taken offline for repairs.

“We are making repairs to a containment valve that had developed a valve packaging leak,” an Exelon spokesperson said in an email response about the status of the plant.

Clinton was listed at zero generation on the Nuclear Regulatory Commission (NRC) daily reactor status report on Jan. 22 after being listed at 54% generation on the same report the previous day.

Companies typically don’t reveal how long they expect repairs to take.

Clinton is a roughly 1,100-MW boiling water reactor (BWR) unit in DeWitt County, Ill. It was commissioned in the 1980s. During 2012 it had a capacity factor of 94%, according to GenerationHub data.

Exelon has identified Clinton as one of its Illinois nuclear plants that could have a difficult time surviving in present market conditions. Exelon, the nation’s largest nuclear operator, has also said that Illinois will have a tough time complying with proposed federal carbon regulations without all of its current nuclear plants.
