Oak Ridge, Tennessee 1943-1987

Located on the southwestern end of the Oak Ridge Reservation in Tennessee, the Oak Ridge Gaseous Diffusion Plant (K-25) enriched uranium through gaseous diffusion to separate uranium-235 from uranium-238. Gaseous diffusion was a process that provided uranium for the Hiroshima weapon (Little Boy). Beginning in 1943 and completed in early 1945, the K-25 plant employed 12,000 workers and at its peak, it contained five uranium enrichment facilities. K-25 was the prototype for other Oak Ridge plants such as those at Paducah and Portsmouth.
