Braidwood Generating Station is located in Will County in northeastern Illinois, USA. The nuclear power plant serves Chicago and northern Illinois with electricity. The plant was originally built by Commonwealth Edison company, and subsequently transferred to Com Ed's parent company, Exelon Corporation.
This station has two Westinghouse pressurized water reactors. Unit #1 came online in July 1987. Unit #2 came online in May 1988. The units are licensed by the Nuclear Regulatory Commission to operate until 2026 and 2027.[1]
The recent[when?] power uprates at Braidwood make it the largest nuclear plant in the state, generating a net total of 2,242 megawatts. However the three largest Illinois nuclear power plants are nearly equal in generating capability as LaSalle County Nuclear Generating Station is only 2 MW less in capacity than Braidwood and Byron Nuclear Generating Station is only 4 MW less than LaSalle.

Surrounding population
The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.[2]
The 2010 U.S. population within 10 miles (16 km) of Braidwood was 33,910, an increase of 6.5 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 miles (80 km) was 4,976,020, an increase of 5.3 percent since 2000. Cities within 50 miles include Joliet (20 miles to city center).[3]
Tritium leaks
Exelon was sued by residents of Will County and by the state's attorney in 2006.[4] The lawsuit alleges that the Braidwood plant released radioactive tritium into local water in violation of its permit.[5][6] However, the US NRC has said the response is based on "emotion, not risk", and gone on record to state the tritium releases did not jeopardize human health or safety in any manner.[7] The Illinois EPA has also said all tests have confirmed releases are below the action levels of 20,000 picoCuries per liter, currently set by the EPA. However, bottled water will be provided to residents of Godley and to residents within 1500 feet of the line.[8]
Seismic risk
The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Braidwood was 1 in 136,986, according to an NRC study published in August 2010.[9]
