Cleanup of historic Uravan uranium mill completed

An early mill on the site provided radium for Madam Curie's research efforts. In 1942, the U.S. Army Corps of Engineers built facilities to process uranium in Uravan and during the 1940s the mill processed uranium for the Manhattan Project. Later, uranium produced from the Uravan mill was used to fuel nuclear power plants.
