OAK RIDGE, Tenn. (AP) -- A former nuclear enrichment plant may be too far gone to be preserved as a relic of the atomic bomb-building Manhattan Project of World War II.
Federal energy officials say the K-25 building is unsafe for any type of work other than to bring it down.
The mile-long, U-shaped building is where uranium isotopes were separated into fuel for bombs and nuclear reactors from the 1940s until the 1980s.
It now stands as an off-limits hulk in the heart of a complex of buildings the government has been working for more than a decade to convert into an industrial park.
It's listed as one of the "signature facilities" of the Manhattan Project.
