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 new polarizers with grooved mirrors were installed in ECRH system on the GAMMA 10 to get the optimal polarized wave. Numeric calculation and low power performance test of this pair of polarizers was agreed well. And it is found that the setting error of polarizer angle within ±5° gives negligible reduction of the X-mode ratio less than 1%. On the experiment in the GAMMA 10, it is shown that the fraction of X-mode has key role to heat plasma efficiently.
