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

Many different classes of materials are required in the development of advanced Rankine systems. These materials include nuclear fuels in the reactor, refractory metal alloys for alkali metal containment, electrical materials for the alternator, and stainless steel for the radiator. The ceramics uranium carbide and uranium dioxide are presently being considered as reactor fuels for this system. Of the numerous refractory metal alloys available, the tubing alloys FS-85 (Cb-10W-28Ta-1Zr), T-111 (Ta-8W-2Hf), and T-222 (Ta-10.4W-2.4Hf-0.01C), have survived the welding, thermal aging, and mechanical property screening tests. Based on long-time creep data, the alloys TZC (Mo-1.25Ti-0.15Zr-0.12C), TZM (Mo-0.5Ti-0.08Zr), and Cb-132M (Cb-20Ta-15W-5Mo-2Zr-0.13C) appear the best for turbine rotor applications. Long-time property data are becoming available for electrical materials for applications up to 1000°F, and new electrical materials are being developed for higher temperatures. Cermets with properties suitable for applications as alkali-metal-lubricated bearing materials are available. Stainless steel operating below 1400°F will probably be used in radiators for this system.
