Hanford Site

The Hanford Site was established in 1943 as part of the Manhattan Project. At this time large industrial facilities were built to produce plutonium, which served an important role in the nation’s defense. The site’s mission expanded during the Cold War era to include research and development activities associated with the peaceful uses of atomic energy. Today the remains of the facilities and legacy wastes document an important part of the nuclear age story.
