Oak Ridge, Tennessee 1943 – 2000

Similar to K-25, the Y-12 Plant was constructed to separate the fissile isotope uranium-235 from uranium-238. More than 22,000 workers worked at the plant, helping separate uranium for use in the Little Boy bomb. In the 1950s, new processes for separating lithium-6 were added. In 1990, with the end of the Cold War, the plant’s mission evolved into weapons reduction and disassembly. Today, the plant is under the jurisdiction of the National Nuclear Security Administration and is focused on remediating mercury and other contaminants that were released into the environment.
