The Limerick Generating Station in Pennsylvania is located next to the Schuylkill River in Limerick Township, Montgomery County, northwest of Philadelphia. The facility has two General Electric boiling water reactor (BWR) units, cooled by natural draft cooling towers. When conditions are right, these cooling towers emit enough water vapor to be seen as far away as Centralia in Columbia County. The two units are capable of producing over 1,200 megawatts of power each, which combined would provide electricity to over 2 million households. Exelon Corporation owns and operates this facility. For critical standby power, Exelon depends on eight Fairbanks Morse Opposed Piston 38D 8 1/8 Emergency Diesel Generator sets that each deliver 3000 kilowatts of power and are capable of achieving rated speed within ten seconds of start. ==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 Limerick was 252,197, an increase of 18.7 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within was 8,027,924, an increase of 6.1 percent since 2000. Cities within 50 miles include Philadelphia (28 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「Limerick Generating Station」の詳細全文を読む スポンサード リンク
