Communities
- 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

Brian D. Wirth
Department of Nuclear Engineering, University of Tennessee, Knoxville

Brian D. Wirth will introduce the Metallurgy and Materials Science sessions with a discussion of "Multiscale Materials Modeling of Radiation Damage and Defect/Microstructural Evolution in Materials: Impact of He/dpa Ratio" The presentation will focus on the effect of a noble gas, helium, which is produced by alpha decay of plutonium, and how that influences the long-term aging behavior of plutonium, including changes in thermal-physical properties. The expected behavior of plutonium aging due to alpha decay will be compared and contrasted from what we know about helium behavior, and in particular the production rate of helium to displacement damage, from materials used in nuclear energy.
