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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Understanding the tritium behavior in breeder materials is essential for the safe and economic operation of fusion reactor. In this paper, the effect of grain size on bulk diffusion of hydrogen isotope in ternary lithium oxide was studied. LiNbO3 single-crystal samples of different grain sizes were used: cubic samples (a) 4.7×4.7×4.7 mm3, (b) 1.5×1.5×1.5 mm3, and (c) 0.46×0.46×0.46 mm3; powder sample (d) 45 m (a.v). With the grain size of cubic samples decreasing, it was clearly observed that the position of TDS peak related to bulk diffusion moved to a lower temperature because of shorter diffusion path. In comparison with computational simulation based on a diffusion model, a fair agreement between experiment and calculation was obtained.
