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 and 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."〔(【引用サイトリンク】 title= Oconee Nuclear Station )〕 In the summer of 2011 it became the first nuclear plant in the United States to have its sensors controlled digitally.〔http://www.kansascity.com/2011/05/29/2912054/sc-nuclear-plant-becoming-1st.html〕 ==Surrounding population== The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of , concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about , concerned primarily with ingestion of food and liquid contaminated by radioactivity.〔http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/emerg-plan-prep-nuc-power-bg.html〕 The 2010 U.S. population within of Oconee was 66,307, an increase of 11.5 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within was 1,404,690, an increase of 14.8 percent since 2000. Cities within 50 miles include Greenville (30 miles to city center).〔Bill Dedman, Nuclear neighbors: Population rises near US reactors, ''msnbc.com'', April 14, 2011 http://www.msnbc.msn.com/id/42555888/ns/us_news-life/ Accessed May 1, 2011.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oconee Nuclear Station」の詳細全文を読む スポンサード リンク
