Limerick Unit 1 Returns to Service Following Shutdown
Exelon Nuclear’s Limerick Generating Station Unit 1 resumed producing electricity earlier this morning following an unplanned trip of the Unit 1 turbine.
POTTSTOWN, Pa. – Exelon Nuclear’s Limerick Generating Station Unit 1 resumed producing electricity earlier this morning following an unplanned trip of the Unit 1 turbine.
Early Friday morning, workers at Limerick Generating Station were performing testing on plant instrumentation when the Unit 1 turbine tripped offline, automatically shutting down the unit.
The plant is designed to shut down the reactor automatically as a safety precaution when such an event occurs. Limerick operators and maintenance technicians worked around the clock performing numerous tests to identify the cause of the problem associated with the turbine coming offline and to ensure corrective measures were implemented to prevent recurrence.
There was no risk to the public, and operators restored the unit to service safely and without incident.
Limerick Unit 2 continued to generate electricity during the Unit 1 outage. Limerick Generating Station is located approximately 21 miles northwest of Philadelphia.
