Operators at the nuclear plant manually shut down the reactor safely and are investigating the cause of the pump malfunction.
The generator and the pump are located on the non-nuclear side of the plant.
Exelon’s Byron Nuclear Generating Station is located in Ogle County, Illinois, US about 2 miles east of the Rock River.
The nuclear plant has two units each with a power generating capacity of 1,168MW. At full power generation capacity, the two units can produce enough electricity for about 2.3 million homes.
During the shutdown of the unit 2 reactor, Byron Unit 1 will continue to operate at full capacity.
