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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

A computational study of the thermodynamic and elastic properties of the tungsten-berylliuminterface structure and the behavior of a helium-vacancy pair near the tungsten/beryllium interface is carried out by first-principles calculations. Briefly, the following properties were calculated: (1) electronic properties of the tungsten/beryllium interface structure and (2) thermodynamic functions, Gibbs free energy, entropy, and enthalpy and anisotropies and isotropic (poly-crystalline) elastic moduli (bulk, torsion, Young’s moduli) of the tungsten/beryllium interface structure containing helium interstitial atoms or helium-vacancy pairs. The computational study was to provide a critical appraisal of the effect of helium interstitial atoms on the properties of the tungsten/beryllium interface structure. Calculated interface properties could be incorporated in an antiradiation damaging feature evaluation system to develop and test tungsten-based composites as plasma-facing materials.
