WASTE TREATMENT PLANT2014 ACCOMPLISHMENTS

Bechtel National Inc. is designing and building the world’s largest radioactive waste treatment plant for the U.S. Department of Energy at the Hanford Site in southeastern Washington state. The Waste Treatment Plant, also known as the Vit Plant, will use a process called vitrification to solidify the radioactive liquid waste stored in 177 underground tanks.

Vitrification involves blending the waste with glass-forming materials and heating it to high temperatures. The molten 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 Vit Plant will cover 65 acres with four major facilities – Pretreatment, Low-Activity Waste Vitrification, High-Level Waste Vitrification and Analytical Laboratory – as well as operations and maintenance buildings, utilities, other support facilities, and office space.
