LIMERICK PA – What was described as “an electrical disturbance on the non-nuclear side of the plant” caused operators of Exelon Nuclear’s Limerick Generating Station, 3146 Sanatoga Rd., to take its Unit 1 generator off-line Wednesday (July 18, 2012) at about 8:39 a.m., Communications Manager Dana Melia said. A cause, if known, was not announced.
The disturbance caused a loss of power to generator cooling equipment, according to Melia, and prompted operators to declare the occurrence of an “unusual event,” in keeping with federal Nuclear Regulatory Commission procedures. Unit 1 is expected to remain down until repairs, inspections and testing can be completed.
Limerick’s Unit 2 continues to operate at full power.
Exelon reported it had notified federal, state and local government officials of the event, which officially ended at 9:46 a.m. An unusual event is the lowest of four Nuclear Regulatory Commission emergency classifications.
Exelon also declared there was “no threat to the health and safety of the public” as a result of the power loss.
