Vision 2020 celebrates the cleanup of the East Tennessee Technology Park, formerly the Oak Ridge Gaseous Diffusion Plant – codenamed K-25. K-25 was built in unprecedented secrecy in the 1940s as part of the Manhattan Project to provide enriched uranium for the world’s first atomic bomb.

Cleanup of the site included more than 500 facilities, at the heart of which were five massive uranium enrichment buildings. Since the site was officially closed in 1987, DOE work has focused on transforming it into a multi-use industrial park, national park, and conservation area.

Achieving Vision 2020 marks the first time in the world an entire enrichment complex has been cleaned and demolished.
