The Hanford Tank Waste Treatment and Immobilization Plant, known as the Vit Plant, will process the nuclear waste at the Hanford Site in Washington into a solid glass form using vitrification. A proven technology that has been used at the Savannah River Site and West Valley Demonstration Project, vitrification involves mixing the waste with glass-forming chemicals, heating it to 2,100 degrees Fahrenheit, and pouring it into stainless steel containers to solidify.
