Surry Power Station is a nuclear power plant located in Surry County in southeastern Virginia, in the South Atlantic United States. The power station lies on an site adjacent to the James River across from Jamestown, slightly upriver from Smithfield and Newport News. Surry is operated by Dominion Generation and owned by Dominion Resources, Inc. The plant has two triple-loop Westinghouse pressurized water reactors which went on-line in 1972 and 1973 respectively. Each reactor produces approximately 800 megawatts of power, for a combined plant output of 1.6 gigawatts. Surry Power Station draws its condenser cycle water directly from the James River, removing the need for the imposing cooling towers often associated with nuclear plants. Repeated testing shows that Surry Power Station has minimal environmental impact and releases virtually no radiation or harmful emissions. The station site was originally designed for four units; however, only two reactors were built. With increasing energy demands in the United States, it is possible that more reactors will be built at Surry in the next few decades. In 2003, the Nuclear Regulatory Commission (NRC) extended the operating licenses for both reactors from forty to sixty years. The Surry plant is similar in appearance and design to its "sister plant" North Anna Power Station, located northwest of Richmond in Louisa County, Virginia. Surry was one of the plants analyzed in the NUREG-1150 safety analysis study. ==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 Surry was 127,041, an increase of 21.9 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within was 2,292,642, an increase of 13.9 percent since 2000. Cities within 50 miles include Virginia Beach (47 miles to city center), Norfolk (30 miles to city center), Richmond (50 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「Surry Nuclear Power Plant」の詳細全文を読む スポンサード リンク
