NEW YORK, Oct 27 (Reuters) – Exelon Corp’s (EXC.N: Quote, Profile, Research, Stock Buzz) 619-megawatt Oyster Creek nuclear power station in New Jersey shut by early Monday, the U.S. Nuclear Regulatory Commission said in a report.
On Friday, the unit was operating at 94 percent of capacity as it coasted down for a planned month-long refueling and maintenance outage expected to start in late October.
Electricity traders guessed the unit shut for the refuel.
Oyster Creek, the oldest operating nuclear reactor in the nation, is in Forked River in Ocean County, about 60 miles east of Philadelphia. It entered service in 1969.
One MW powers about 800 homes in New Jersey.
In July 2005, Exelon applied with the U.S. Nuclear Regulatory Commission to renew the plant’s original 40-year operating license for another 20 years.
In September 2008, a federal review board held a hearing related to Exelon’s proposal to inspect the plant’s drywell, which was the subject of a contention filed with the NRC by a group of environmental and community organizations opposed to the license renewal.
So long as the renewal process is ongoing, Exelon can continue to operate the plant even after the license expires in 2009.
Exelon’s AmerGen Energy Co subsidiary owns the station, while its Exelon Generation Co LLC subsidiary operates it.
Exelon, of Chicago, owns and operates more than 38,000 MW of generating capacity, markets energy commodities. It transmits and distributes electricity to 5.4 million and distributes natural gas to 480,000 customers in Illinois and Pennsylvania. (Reporting by Scott DiSavino; Editing by John Picinich)
