| Abstract: | Two remote-controlled robotic submersible vehicles and an automated shredder are helping remove and dispose of highly reactive, sometimes explosive materials, dumped into a water-filled quarry at the U.S. Department of Energy's reservation in Oak Ridge, Tennessee. Human workers never enter the four-acre site, except for well-planned equipment maintenance and to shoot holes from a protected but into the retrieved containers, releasing pressure and exposing the contents to air and water. During its approximately two years of operation, the $8 million project has retrieved more than 15,000 items from the thirty feet of water at the bottom of the quarry. |
