POTTSTOWN, PA - Exelon Nuclear's Limerick Generating Station Unit 2 resumed producing electricity today after workers completed repairs to a turbine control valve that caused a turbine trip and subsequent automatic shutdown of the reactor on Sunday.
Early Sunday morning, plant workers had completed testing of Unit 2's Electro Hydraulic Control (EHC) system, which controls the opening and closing of turbine valves, when the turbine tripped offline. 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 to identify and resolve the problem associated with the valve, which is part of the non-nuclear side of the plant. There was no risk to the public, and operators restored the unit to service safely and without incident.
Limerick Unit 1 continued to generate electricity during the Unit 2 outage.
Limerick Generating Station is located approximately 21 miles northwest of Philadelphia.
