The Uranium-233 Disposition Project is the Oak Ridge Office of Environmental Management’s (OREM) highest priority project at the Oak Ridge National Laboratory (ORNL). Isotek Systems is OREM’s contractor responsible for leading the project. Originally created in the 1950s and 1960s for potential use in reactors, uranium (U)-233 proved to be an unviable fuel source.

Eliminating the inventory of U-233 at ORNL is urgent because it is highly enriched fissile material stored in the world’s oldest operating nuclear facility. This material presents risks and is costly to keep safe and secure. Read the fact sheet to learn more about the work underway to address this material.
