  In 1942, the federal government established the K-25 site and the S-50 site at the Oak Ridge Reservation to produce enriched uranium for nuclear weapons. In October 1944, the S-50 plant began separating uranium by liquid thermal diffusion, but closed less than one year later in September 1945. In 1946, all of the buildings associated with the S-50 site were destroyed.
  
  The K-25 site (formerly referred to as the Oak Ridge Gaseous Diffusion Plant) remained operational from 1945 to 1964, enriching weapons-grade uranium through gaseous diffusion. From 1965 to 1985 at K-25, uranium hexafluoride subjected to the gaseous diffusion process became commercial-grade uranium. In 1985, all gaseous diffusion operations ceased at K-25, and in 1987, the site closed. The K-25 site is currently known as the East Tennessee Technology Park. In the past, these K-25/S-50 operations generated a variety of radioactive and nonradioactive wastes and consequently some waste was released into the environment.
