The Duane Arnold Energy Center (DAEC) is located on a 500-acre (200 ha) site on the west bank of the Cedar River, two miles (3.2 km) north-northeast of Palo, Iowa, USA, or eight miles (13 km) northwest of Cedar Rapids. It is Iowa's only nuclear power plant.
DAEC entered operation in June 1974. It currently generates a net power output of approximately 615 megawatts using a single General Electric BWR 4 boiling water reactor inside of a Mark 1 pressure suppression type containment.
The majority owner and operator is NextEra Energy Resources (70%). The Central Iowa Power Cooperative owns 20% and the Corn Belt Power Cooperative owns 10%.
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.
The 2010 U.S. population within 10 miles (16 km) of Duane Arnold was 107,880, an increase of 8.2 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 658,634, an increase of 7.1 percent since 2000. Cities within 50 miles include Cedar Rapids (10 miles to city center).
In the late 1960s, Iowa Electric Light & Power Co. (now Alliant Energy - West), Central Iowa Power Cooperative and Corn Belt Power Cooperative applied for a nuclear plant license with the Atomic Energy Commission (AEC). On June 17, 1970 a construction permit was granted and work began. The original plan was to complete construction in 40 months at an estimated cost of $250 million.
