The K-25 building at the K-25 site in Oak Ridge, Tennessee, was the first gaseous diffusion plant to perform large-scale separation of uranium isotopes beginning in June 1945. Additional gaseous diffusion buildings were added at the K-25 site to provide enriched feed (20% {sup 235}U) to the K-25 building, which further enriched the uranium to {approximately}90% {sup 235}U. The K-25 building operated as the top of the K-25 site cascade until 1964, when the building was shut down and downgraded to abandoned in place in 1977. Due to the 20 yr of production of highly enriched uranium (HEU), the K-25 building contains residual quantities of uranium held up in the equipment and piping.
