Exelon NJ Oyster Creek reactor up to 90 pct power

NEW YORK, July 9 (Reuters) - Exelon Corp's (EXC.N) 619-megawatt Oyster Creek nuclear power station in New Jersey ramped up to 90 percent power by early Thursday from 60 percent early Wednesday, the U.S. Nuclear Regulatory Commission said in a report.

Operators reduced the unit earlier in the week to work on the condenser.

Oyster Creek, which entered service in 1969 making it the oldest operating reactor in the nation, is located in Forked River in Ocean County about 60 miles east of Philadelphia. The NRC renewed the plant's original 40-year operating license in April 2009 for another 20 years until 2029.

One MW powers about 800 homes in New Jersey.

Exelon, of Chicago, owns and operates more than 38,000 MW of generating capacity, markets energy commodities, and transmits and distributes electricity to 5.4 million and distributes natural gas to 480,000 customers in Illinois and Pennsylvania.
