The Electromagnetic Separation Plant was a Manhattan Project facility built in 1943 to separate U-235 from U-238. Material for the first atomic bomb was produced here. In place of unavailable copper, nearly 14,000 tons of silver were borrowed from the U. S. Treasury for use on the manufacturing equipment. The plant was constructed by Stone and Webster Engineering and was operated by Tennessee Eastman from 1943-1947.
