Operators at Exelon Nuclear's Oyster Creek Generating Station safely returned the station to service Thursday, Dec. 16 at 4:30 p.m. ET after completing the replacement of a main power transformer.
The plant had operated at reduced power since Dec. 12 after one of its two transformers produced abnormal readings during startup proceedings following November's refueling outage. That transformer was replaced with the station's spare transformer this week.
There was no impact on aquatic life in the station's discharge canal during the maintenance period.
Oyster Creek is located approximately 60 miles east of Philadelphia. The plant produces 636 net megawatts of electricity per hour, enough carbon free energy for approximately 600,000 homes, the equivalent of all of the homes in Mercer, Burlington and Ocean counties.
