Iowa (/ˈaɪəwə/ (listen)) is a state in the Midwestern United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north.
In colonial times, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt.
In the latter half of the 20th century, Iowa's agricultural economy made the transition to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production. Iowa is the 26th most extensive in land area and the 30th most populous of the 50 U.S states. The state's capital, most populous city, and largest metropolitan area fully located within the state is Des Moines. A portion of the larger Omaha, Nebraska, metropolitan area extends into three counties of southwest Iowa. Iowa has been listed as one of the safest states in which to live.
The Duane Arnold Energy Center (DAEC) is Iowa's only nuclear power plant. It 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.
DAEC entered operation in February 1975. 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. Read more...
