DOE-EM finishes cleanup of legacy Oak Ridge reactor lab site
The Department of Energy’s Office of Environmental Management announced that the 30-foot-long, 37,600-pound reactor vessel from Oak Ridge National Laboratory’s Low Intensity Test Reactor was shipped to EnergySolutions’ low-level radioactive waste facility in Clive, Utah, in late April.

Because of the presence of high cyclic thermal stress, coolant pressure-induced primary stress, and disruption-induced high cyclic primary stress, ratcheting (i.e., incremental accumulation of plastic strain) in the first wall poses a serious challenge to the designers of the U.S. International Thermonuclear Experimental Reactor (ITER). Existing design tools, such as the Bree diagram in the American Society of Mechanical Engineers Boiler and Pressure Vessels Code, are not directly applicable to the U.S. ITER because of important differences in geometry and loading modes. Available alternative models for ratcheting are discussed, and new Bree diagrams, which are more relevant for fusion reactor applications, are proposed.
