Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 oxidation activity of molecular tritium (HT) in soils and vegetation collected in experimental plots during the 1994 chronic HT release experiment at Chalk River was determined in in vitro laboratory experiments after the release. HT oxidation activity was highest in surface soils in the natural plot, about 3–4 times that in soils in the cultivated plots. HT oxidation activity in weeds and Komatsuna leaves was about 2 and 0.4 % of that in the cultivated soil, respectively. The number of HT-oxidizing bacteria isolated from soils was highest in the surface soil (0–5 cm) in the natural plot. The viable cell numbers in surface soils in the cultivated and natural plots were almost the same. The total occurrence rates of HT-oxidizing bacteria in the surface soils were 22 % in the natural plot, and 7.5 % in the cultivated plot. The occurrence rates of HT-oxidizing airborne bacteria during the release on two culture media were 4.2 and 1.9 %.
