High Water Levels Bring Alert Declaration at Oyster Creek 

 Plant shut down last week for refueling  


Forked River , NJ -  Operators at Oyster Creek Generating Station declared an “Alert” at 9 p.m. EDT tonight after water levels in the plant’s intake structure rose 6-feet above mean sea level, the threshold for an Alert declaration.

Oyster Creek was shut down Oct. 22 for planned maintenance and refueling. There is no challenge to plant safety equipment and no threat to the public health or safety associated with the Alert.

About the same time, Oyster Creek also experienced a power disruption in the station’s switchyard. The station’s two backup diesel generators activated immediately and continue to provide a stable supply of power to the station’s systems. The site has more than two weeks of diesel fuel onsite. The site also has two natural gas turbine generators available as additional backup power sources if needed.

Technicians are working to restore power in the switchyard, similar to a large substation that delivers power to and from the plant.

Exelon has staffed on-site and off-site emergency operations centers to monitor weather and plant conditions and to provide updated information to local, state and federal officials.

An Alert is the second lowest of four emergency classifications established by the U.S. Nuclear Regulatory Commission.

Oyster Creek is about 60 miles east of Philadelphia in Ocean County, New Jersey. The plant produces 636 net megawatts of electricity at full power, enough electricity to supply 600,000 typical homes, the equivalent to all homes in Monmouth and Ocean counties combined. In addition, plant workers, through their payrolls, are responsible for more $96 million injected directly into New Jersey’s economy.
