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

Two-phase cross flows have received minor consideration in thermal-hydraulics research, notwithstanding their applications in chemical engineering systems. Many types of heat exchangers and steam generators have, at least in a segment of the flow path, a cross direction of a two-phase mixture to a tube bank even in nuclear plant components. The departure from nucleate boiling (DNB), or the dry-out threshold, is one of the main limits that characterize the whole flow field. For this reason it has been deemed interesting to investigate the influence of quality on DNB heat flux in flow boiling, employing a 9-tube bundle with cross flow of Freon 12. Rather surprisingly, the DNB heat flux rises with quality. The rise has been tested from the pool boiling DNB value as predicted by Lienhard up to a saturation value 20% higher. The law of increase may be reasonably well predicted following the well-known critical heat flux theory of Zuber.
