GAO: Clarification of HLW definition could save DOE billions
A clearer definition of what constitutes high-level radioactive waste could save the Department of Energy’s Office of Environmental Management “tens of billions of dollars” in waste management costs and accelerate its cleanup schedule by decades, according to a report by the U.S. Government Accountability Office.
DOE-EM’s efforts to manage waste resulting from legacy spent nuclear fuel reprocessing have been hindered for decades by the ambiguity of the statutory definition of HLW as laid out in the Atomic Energy Act and Nuclear Waste Policy Act, the report states. While admitting that the DOE has taken steps to overcome this ambiguity, the GAO says that the department has not fully evaluated all available opportunities to treat and dispose of waste more economically as either transuranic or low-level radioactive waste.

The heat flux and fluid flow conditions for a water cooled limiter tube are simulated with an electron beam heating apparatus, and the results are compared to empirical models based on existing heat transfer correlations. For the conditions of highly subcooled flow boiling in a horizontal tube subjected to a heat flux from only one side, two principal observations were noted. First, existing heat flux correlations, which were developed for use with uniform circumferential heat flux distributions, can be used to provide a good first approximation of the one-sided heat removal for the range of experimental conditions covered. Second, the peak heat flux at the tube surface predicts the onset of critical heat flux (burnout) better than the average heat flux.
