Description
X-ray scattering techniques coupled with the world-class brightness of the National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory (BNL) enable exceptional opportunities for non-destructive studies of nuclear materials such as uranium alloys. Materials for Energy Applications group at Nuclear Science & Technology Department at BNL partners with 28-ID-2 beamline (XPD) of NSLS-II for providing synchrotron-based characterization resources for nuclear science community under the umbrella of Nuclear Science User Facilities (NSUF). The XPD beamline can focus the x-ray beam down to ~25 um in a high-energy regime (>60 keV) and is intended to be a crosscutting tool that will enable multi-modal studies of high-Z materials, a crucial capability for nuclear materials research. In this talk, I will present examples of previous studies conducted as a result of this partnership. Emphasis will be placed on absorption contrast and diffraction contrast tomography of a surrogate TRi-structural ISOtropic particle fuel (TRISO) particle which is known as “the most robust nuclear fuel on earth.”
