The Oconee Nuclear Station is a nuclear power plant located on Lake Keowee near Seneca, South Carolina,
and has an energy output capacity of over 2,500 megawatts. It is the second nuclear power plant in the United States to have its operating license extended for an additional twenty years by the U.S. Nuclear Regulatory Commission (NRC) (the application for the Calvert Cliffs plant in Maryland preceded it).
This plant has three Babcock & Wilcox pressurized water reactors, and is operated by Duke Energy.
Oconee was the first of three nuclear stations built by Duke Energy. According to Duke Energy's web site, the station has generated more than 500 million megawatt-hours of electricity,
and is "the first nuclear station in the United States to achieve this milestone."
In the summer of 2011 it became the first nuclear plant in the United States to have its sensors controlled digitally.
