The K-25 plant, part of the Manhattan Project, was the largest building in the world by floor area when it was completed in 1945, covering 44 acres.
K-25 was instrumental in enriching uranium for the first atomic bombs during World War II.
The construction of K-25 involved over 25,000 workers and was completed in just 18 months, a remarkable feat for its time.
The plant used gaseous diffusion technology to separate uranium isotopes, a cutting-edge process at the time.
Oak Ridge was a 'secret city' during the war, not appearing on maps and requiring special passes for entry.
The site is now part of the East Tennessee Technology Park, focusing on environmental cleanup and redevelopment.
The American Museum of Science and Energy in Oak Ridge features exhibits on the history and impact of K-25.
