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 catalytic oxidation and adsorption is the most conventional and reliable method for removing tritium that is accidentally released into the working area of fusion power plants. The authors conducted a study on the effect of water on the oxidation reaction over a Pt/MS5A catalyst, and it was found that coexistent water inhibit its catalytic activity. With this result, a simulation study was carried out, and its result suggests that the installation of a pre-adsorption bed is very effective.
