Limerick Generating Station Unit 2 Returns to Service Following Planned Fueling Outage

POTTSTOWN, PA - Exelon Nuclear’s Limerick Generating Station Unit 2 resumed producing electricity on April 24, 2011 after completing the unit’s refueling and maintenance outage.

While the unit was shutdown, employees and almost 1,900 supplemental workers replaced one-third of the reactor’s fuel and performed extensive inspections, tests, maintenance and modifications on a variety of components and equipment.

“The refueling outage included 13,000 activities that were performed to prepare the unit for safe and reliable operations through the next 24-month operating cycle,” said Bill Maguire, Limerick site vice president. “One of the most significant projects completed was the replacement of the unit’s three main power transformers to ensure continued reliable operations for many years to come.”

Limerick’s refueling outages are a boost to the local economy. The influx of skilled workers from other Exelon sites, local union halls and specialty vendors from outside the area give local businesses an extra boost as workers dine in the area and need local accommodations.

Limerick Unit 1 continued to generate electricity during the unit 2 refueling and maintenance outage. With both units at full power, the site can produce enough carbon-free electricity for two million homes. Limerick Generating Station is located approximately 21 miles northwest of Philadelphia.
