K-25 was the codename given by the Manhattan Project during World War II for the project to produce enriched uranium for atomic bombs using the gaseous diffusion method. Over time it came to refer to the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site. When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, with over 1,640,000 square feet of floor space and a volume of 97,500,000 cubic feet . The highly corrosive uranium hexafluoride (UF6) was the only known compound of uranium sufficiently volatile to be used in this process. Slightly enriched product from the S-50 thermal diffusion plant was fed into the K-25 gaseous diffusion plant. The enriched uranium was used in the Little Boy atomic bomb used in the atomic bombing of Hiroshima. In 1946, the K-25 gaseous diffusion plant became capable of producing highly enriched product. After the war four more gaseous diffusion plants were added to the site, named K-27, K-29, K-31 and K-33. The K-25 site was renamed the Oak Ridge Gaseous Diffusion Plant in 1955. Production of enriched uranium ended in 1964. Presumed First Edition, First printing thus.…
