Demolition complete on Oak Ridge's K-25 building

What was once the world's largest building under one roof, is gone.

On Thursday, the Department of Energy announced that it has completed demolition of the K-25 gaseous diffusion building.. The five year project was completed ahead of schedule and all debris shipments are expected to be completed in spring 2014.

The K-25 building was located at the East Tennessee Technology Park. It was built in 1943 as part of the Manhattan Project.

"Today marks a tremendous accomplishment for the American people – advancing our commitment to the safe and complete cleanup of former Manhattan Project sites," said Deputy Secretary of Energy Daniel Poneman. "While there is still important clean-up work to do, completing the demolition of the K-25 gaseous diffusion building and doing so ahead of schedule and under budget is a testament to the outstanding Oak Ridge workforce."

The K-25 building operated until 1964, producing enriched uranium for defense and commercial purposes. During the past decades, as the facility deteriorated, its demolition was considered among the highest priorities for the environmental cleanup program in Oak Ridge. Now that the K-25 building is gone, only two of the five original gaseous diffusion buildings remain.

The demolition project began in December 2008.
