Exelon (NYSE: EXC) staff at the 636 MW Oyster Creek Generating Station 60 miles east of Philadelphia returned the plant to the electrical grid August 30. The plant was taken offline August 27 as a precaution in advance of Hurricane Irene.
Operators began a controlled reactor shut-down at 8 a.m. August 27 due to the expected hurricane force winds from Hurricane Irene. The generator stopped producing electricity a little after 5 p.m. By procedure, Oyster Creek is required to shut down if sustained winds reach a certain level during a hurricane.
Exelon personnel made site inspections during and after the storm and determined the facility was not adversely affected by the storm. Exelon staff then informed state and federal emergency management officials, who gave the OK to restart the plant.
