Workers with EM contractor Central Plateau Cleanup Company finished building a protective enclosure, or cocoon, over the former K East Reactor building at the Hanford Site in 2022. The cocoon is designed to protect the reactor building while the radioactivity in the deactivated reactor core decays over the next several decades, making it safer to complete disposition of the reactor in the future. In the third photo above, Hanford Site officials are pictured at a media event marking the project completion.
