K-25
K-25 is a former uranium enrichment facility of the Manhattan Project which used the gaseous diffusion method. The plant was located in Oak Ridge, Tennessee, on the southwestern end of the Oak Ridge Reservation. "K-25" was the name of the first and largest building and also the name of the larger complex, after other "K-" buildings were added.
==History==
The code name "K-25" was a combination of the "K" from the Kellex Corporation, the initial contractors of the plant, and "25," a World War II-era code designation for uranium-235 (element 92, atomic mass 235).〔"Response to letter from Mr. Gus Robinson to General Nichols, providing information relating to Site designations and Site codes for Manhattan District facilities., 10/17/1949", digitized and online as ARC Identifier 281585 at (National Archives Archival Research Catalog ).〕
Work on the facility began in June 1943 and was completed in early 1945 employing 12,000 workers and costing $512 million (equivalent to $ in today dollars). The U-shaped K-25 building measured half a mile by – over . Construction began before completion of the design for the process. Due to construction needs at K-25 and elsewhere on the reservation, the town of Oak Ridge, originally designed for 13,000 people, grew to 50,000 by summer 1944. The people needed for the construction of K-25 lived nearby, in a community that came to be known as Happy Valley. Built by the Army in 1943, Happy Valley was a temporary community that housed 15,000 people in trailer homes.〔(【引用サイトリンク】 work=atomicarchive.com )〕
In the post-war years, additional uranium enrichment facilities were built adjacent to K-25 forming a complex officially known as the Oak Ridge Gaseous Diffusion Plant and commonly called the "K-25 site". Uranium enrichment operations at the K-25 site ceased in 1987.〔(【引用サイトリンク】 work=oakridger.com ) 〕 This entire site is now called the East Tennessee Technology Park.
