Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

The JET Active Gas Handling System has designed and commissioned a new analytical gas chromatography system. The novel design included modification of a basic off-the-shelf gas chromatograph to become tritium compatible and incorporated customised hardware of seven detectors, seven switching valves and seven separation columns into one analytical gas analyser. The functionality of the new system was proven during the inactive commissioning phase and gas species including hydrogen isotope molecules (H2, HD and D2), air components and hydrocarbons up to decane, water and ammonia including mass spectrum data could successfully be analysed. The design of this system is unique and the first of its kind employed in a nuclear fusion laboratory.
