Hanford - Waste Treatment Plant Project

“Bechtel National, Inc. is designing, constructing and commissioning the world’s largest radioactive waste treatment plant for the U.S. Department of Energy (DOE) in Richland Washington. When complete, the Hanford Tank Waste Treatment and Immobilization Plant (WTP) will process and stabilize 56 million gallons of radioactive and chemical waste currently stored at the Hanford Site.

The WTP will use vitrification technology, which involves blending the waste with glass-forming materials and heating it to 2,100 degrees Fahrenheit (1,149 degrees Celsius). The mixture is then poured into stainless steel canisters to cool and solidify. In this glass form, the waste is stable and impervious to the environment, and its radioactivity will dissipate over hundreds to thousands of years.

The WTP Project is scheduled to complete construction in 2016; reach commissioning in 2019 and achieve full operations in 2022.”  (Reference:
