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.

Results of a two-year study of groundwater levels at the site of the planned Environmental Management Disposal Facility (EMDF) in Oak Ridge, Tenn., have been released, revealing that the levels fell at a slower-than-expected rate. The collection of data on groundwater levels during two wet seasons, conducted by the Oak Ridge Office of Environmental Management and the contractor United Cleanup Oak Ridge, formed the core of a groundwater field demonstration study which will help inform the final design of the EMDF landfill.
