Limerick nuclear unit offline for refueling outage

Operators at Exelon Nuclear’s Limerick Generating Station removed Unit 2 from service at 8 am EDT today for a scheduled maintenance outage. During the outage, workers will replace two steam relief valves, essential components of the plant’s steam piping system.

Plant personnel will complete the maintenance and fully test the new components before returning the unit to service. The repairs can only be performed while the plant is offline.

“Careful and continuous monitoring of plant equipment is essential to reliable operations at Limerick Generating Station,” said Russ Kearney, Limerick site vice president. “This maintenance outage will ensure that we can operate safely and reliably during the peak summer season ahead. Our highly trained team is well prepared to perform the scheduled maintenance and return Unit 2 to service for our customers.”

Limerick Unit 1 will continue to operate at full power during the outage. Limerick Generating Station is located approximately 21 miles northwest of Philadelphia.  With both units at full power, the site can produce enough carbon-free electricity for 2 million homes.
