Han Hanford d Nuc uclear lear Sit ite • 586 square miles • Hanford Reach – 50-mile stretch of relatively free-flowing Columbia River • Most contaminated site in the Western Hemisphere • For over 40 years, the United States produced plutonium for nuclear weapons, and released hundreds of billions of gallons of liquid chemical and radioactive waste into the soil and groundwater.

The Board advises the U.S. Department “P “Plutonium is forever... of Energy (DOE) to get as much plutonium out of these waste sites as possible.” – Hanford Advisory Board, Advice 247, June 2011 : Images: U.S. DOE, accessed April 2020.

Wa Waste Encapsulation St Storage Facility (WESF SF) • The Waste Encapsulation and Storage Facility (WESF) provides underwater storage for 1,936 highly radioactive capsules containing the elements cesium and strontium. • From CH2M, “WESF is an aging facility, and DOE is evaluating alternatives for placing the capsules in dry storage. Dry storage would eliminate the possibility of a release of radioactive material in the unlikely event of a major earthquake that might result in loss of pool storage water and overheating and breach of one or more capsules.” • “The removal of these capsules into dry storage is now a very high priority. If the basins, or a pipe under the basins, were to fail, and the basin water levels fell below the top of the capsules, the radiation levels would become so intense that no one could ever approach the building again...This would be a Chernobyl-scale accident. It must be prevented.” – Dirk Dunning, Retired Hanford Expert, September 2017 Photo: WESF capsules. Cherenkov Radiation. U.S. DOE. 2020

“T “The De Department of of Energy gy appears s to o be backpedaling g on on moving g hi highl hly radi dioact ctive e capsul ules es to safer er storage e at Ha Hanford d anytime e soon.” .” – Cleaning up Hanford’s ‘greatest risk’ and other radioactive waste could be shelved for 10 years.
