US-based energy provider Exelon has announced that the unit 2 of its Byron nuclear power station has resumed operation after a temporary shutdown.
The company manually shutdown the unit after malfunction of the main generator cooling pump was reported.
Exelon operators carried out the necessary repairs to a motor associated with the main generator cooling pump and brought the unit back to production.
The generator and the cooling pump are located on the non-nuclear side of the plant.
The Byron nuclear power station located in the Ogle County, Illinois, US about 2 miles east of the Rock River has two units each with a power generating capacity of 1,168MW.
Together both the units can produce sufficient power for about 2.3 million people in the region.
During the outage of the unit 2 reactor, unit 1 was operating at its full capacity.
