The last wall of the last of the big five buildings once used to enrich uranium at the former K-25 site will be demolished Tuesday.
Demolition on the last building, the K-27 Building, started in February.
The other four buildings—K-25, K-29, K-31, and K-33—were demolished between 2006 and 2015. All five of the huge buildings once used a process called gaseous diffusion to produce highly enriched uranium for atomic weapons and commercial nuclear power plants, starting during World War II and continuing through the Cold War. The largest was K-25, a mile-long U-shaped building.
When K-27 demolition is complete, it will be the first time that all of a site’s uranium-enriching gaseous diffusion buildings will have been cleaned up anywhere in the world, officials said.
“Demolition eliminates environmental hazards and prepares the land for productive reuse through deindustrialization,” a media advisory said. [Read more…]
