Exelon takes LaSalle 2 nuclear unit offline for pump maintenance

Exelon (NYSE:EXC) removed the LaSalle County 2 nuclear generator in Illinois offline early Friday, Aug. 7, to perform planned maintenance on two pumps that circulate water inside the reactor.

This work cannot be performed while the unit is in operation, Exelon Generation said in a statement. Exelon operates the nation’s largest nuclear power fleet.

LaSalle Unit 1 remained in service and running at 100% power, according to Nuclear Regulatory Commission (NRC) data published early Aug. 7.

LaSalle Station is about 75 miles southwest of Chicago near Marseilles, Ill. At full power, the facility’s two boiling water reactor (BWR) generating units produce more than 2,200 MW of carbon-free electricity.

The company is seeking a 20-year license extension for the two LaSalle nuclear units.

Much of Exelon’s nuclear fleet in Illinois market has been financially struggling in a market with flat power demand, low electricity prices and “subsidized” renewable generation, the company has said.

The company has been pursuing options such as a low-carbon standard in Illinois and doing well in the upcoming PJM auctions in order to preserve the in-state nuclear fleet.
