Innovation has been required as federal cleanup crews work to deactivate and demolish the final portion of the former Radioisotope Development Laboratory at Oak Ridge National Laboratory.
The structure is known as the East Cell Bank, and it is on the U.S. Department of Energy’s list of high-risk excess contaminated facilities, said a press release from DOE Office of Environmental Management. The East Cell Bank is located in the heart of ORNL, near ongoing research missions.
Workers with cleanup contractor UCOR characterized the final cell to identify potential radiological and hazardous contamination, the press release said. They conducted the work in stages under a six-story protective structure erected to ensure nearby facilities and ongoing research missions at ORNL aren’t impacted by the cleanup.
The crews began by taking surveys and readings from an opening at the front of the structure, the release said. They used long-reach tools and a specialized radiation detector. The detector overlays a radiation-intensity color map on a picture of the environment and identifies gamma-ray emitting nuclides and their locations.
