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 kinetics of the sorption of molecular hydrogen by ZrCo and Zi0.8Ti0.3Mn1.9 was investigated as function of temperature at several constant pressures of hydrogen. A comparison between the isothermal hydrogen sorption rates by ZrCo, Zr0.8Ti0.3Mn1.9 and LaNi4.7A10.3 is given and reaction mechanisms are discussed. From fittings of the experimental results to well known gas/solid reaction rate laws it was concluded that the reaction mechanisms of the reaction with ZrCo is complex and dependant upon the prevailing reaction conditions. The hydrogen sorption rate by the powder of all three IMC's was found to be second order in hydrogen pressure.
