The Manhattan Project at Hanford

Nuclear reactors at Hanford (now the Hanford Site) produced plutonium for the Manhattan Project to fuel the first atomic test and the Fat Man atomic bomb dropped on Nagasaki, Japan on August 9, 1945. The story of the Manhattan Project at Hanford encompasses historic facilities and educational centers with the National Park Service, the US Department of Energy and the communities where Hanford workers and their families lived, which are all part of the Tri-Cities region today.
