New lab at ORNL speeds up U-233 cleanup, Ac-225 delivery
A new analytical laboratory at Oak Ridge National Laboratory has been officially opened by the Department of Energy’s Oak Ridge Office of Environmental Management and its contractor Isotek Systems. The state-of-the-art lab, located in Building 2026, is being used to speed up the high-priority cleanup of ORNL’s uranium-233 inventory and accelerate the delivery of actinium-225 to facilities that use the radioisotope in research and for potential treatment of patients with cancer.

This panel will examine new technologies being explored to address the impacts of uranium contamination on former mining and mill tailing sites in the southwest. The panel will cover the research and efforts to use technologies such as evapotranspiration covers, permeable reactive barriers, and in situ remediation. The panel will also provide updates and lessons learned on major sites undergoing remediation, including outreach efforts to inform Navajo communities about the risks that uranium mines pose, such as the recent Uranium 101 Workshop in Arizona.
