Monticello Nuclear Generating Plant

The Monticello Nuclear Generating Plant is a nuclear power plant located in Monticello, Minnesota, along the Mississippi River. The site, which began operating in 1971, has a single nuclear reactor of the General Electric BWR-3 design generating 671 MWe. The reactor was originally licensed until 2010; a renewal license issued in 2006 allows it to continue operating until September 8, 2030.
The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles , concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles , concerned primarily with ingestion of food and liquid contaminated by radioactivity.
