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.

Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

Particle fluxes on surfaces are difficult to calculate with Monte Carlo methods because the score requires a division by the surface-crossing angle cosine, and grazing angles lead to inaccuracies. The traditional method for dealing with this problem was recently extended by recognizing the assumptions that were implicit in its derivation. More recently, a kernel density estimator (KDE) has been proposed to replace the traditional method. In this technical note, example problems from the KDE development are analyzed, and the failure of the traditional method is shown to be due to the invalidity of one of the implicit assumptions, as previously predicted, and the extended theory is used to correct the traditional method.
