The Y-12 National Security Complex is a United States Department of Energy National Nuclear Security Administration facility located in Oak Ridge, Tennessee, near the Oak Ridge National Laboratory. It was built as part of the Manhattan Project for the purpose of enriching uranium for the first atomic bombs. It is considered the birthplace of the atomic bomb. In the years after World War II, it has been operated as a manufacturing facility for nuclear weapons components and related defense purposes. Y-12 had the mission to maintain the safety, security and effectiveness of the U.S. nuclear weapons stockpile. Their portion of the over mission includes weapons component production, surveillance, dismantlement, and storage are four distinct facets of this mission. Production includes the manufacture of new components, which oftentimes are combined with recycled components into subassemblies. This process, referred to as refurbishment, extends the lifetimes of systems in the active weapons stockpile and ensures their effectiveness. Another aspect of this mission is surveillance testing, which determines how weapons in the active stockpile are aging. Dismantlement involves separating components of retired weapons and recovering nuclear materials. Storage occurs throughout all of these processes.

It was built as part of the Manhattan Project for the purpose of enriching uranium for the first atomic bombs. It is considered the birthplace of the atomic bomb. In the years after World War II, it has been operated as a manufacturing facility for nuclear weapons components and related defense purposes. The Y-12 facility began operating in November 1943, separating uranium-235 from natural uranium, which is 99.3% uranium-238, by using calutrons to perform electromagnetic isotope separation. Y-12 separated the uranium-235 for Little Boy, the nuclear weapon that was dropped on Hiroshima, Japan on August 6, 1945. K-25, another facility in Oak Ridge, produced enriched uranium using gaseous diffusion. However, K-25 did not begin operating until March 1945 and fed slightly enriched uranium to Y-12's Beta Calutrons as the push to obtain enough uranium 235 for Little Boy came in the early summer of 1945.
