Exelon Corp. (EXC) said Thursday that it had to shut down a unit of the Limerick nuclear power plant in Pennsylvania after a power outage that affected plant equipment.
The plant's operators shut down Unit 1 at the plant, in Pottstown, Pa., after the plant's main generator cooling pumps lost electricity, Exelon said in a statement. The operators were still working to determine the cause of the electrical malfunction, which the company said was on the "non-nuclear" side of the plant.
The plant's Unit 2 was operating at full power, the company said.
Each unit has about 1,100 megawatts of capacity and together can serve about 2 million homes.
