100 K Area

Aerial of 100K area October 2022

Aerial photo of the 100 K Area at the Hanford Site in October 2022, with the "cocooned" K East Reactor on the right, the K West Reactor on the left and the Columbia River in the background. 

 

The K East and K West reactors and associated spent fuel storage basins were built in the mid-1950s in support of Hanford’s plutonium production mission. The fuel storage basins provided temporary storage of irradiated fuel discharged from the reactors prior to shipment to fuel processing facilities at the Hanford Site. In October 2022 workers completed construction of the K East Reactor Interim Safe Storage enclosure, a process known as "cocooning."

For more information, please see the 100 K Area Fact Sheet.

     In October 2022, teams completed placing the K East Reactor in Interim               Safe Storage to protect it while radioactivity in the deactivated  reactor                 core decays over several decades.
