LIMERICK PA – Exelon Corp. operators returned its nuclear-powered Limerick Generating Station Unit 2 to full power Thursday (May 1, 2014), and reported it successfully completed main turbine inspections. Inspections could not be performed while the unit was generating electricity, company representative Dana Melia said.
Unit 2 was taken off-line April 23 at 7 a.m., in what the company at the time said was a planned event.
During the Limerick Unit 2 outage, workers performed comprehensive equipment inspections and replaced one low-pressure turbine blade. The action was in part based “on turbine blade monitoring data and information gathered during (a) Unit 1 refueling outage earlier” in April, Melia said. Limerick’s Unit 1 reactor continued to operate at full power during the Unit 2 outage.
Turbine blades within each unit are turned by steam created when the nuclear reactors heat water to its boiling point. The blades turn main generators that produce enough electricity to power about 2 million homes, according to company information.
Vehicle traffic along Evergreen and South Sanatoga roads in Limerick and Lower Pottsgrove townships was somewhat heavier turning the outage, as experts and crews from outside the area swarmed into the Exelon cite to perform the maintenance work.
