Abstract Scope |
Nuclear fuel material is of high interest due to the increasing demand for clean energy. But many challenges are still presented in characterizing the fuel to guide the synthesis process. Conventional characterization techniques (i.e. scanning electron microscopy, optical microscopy, etc.) were widely used in the past, but they are often destructive and time-consuming in sample preparation. Moreover, extracting meaningful bulk information and post-irradiation information can be challenging. In this work, attenuation-based neutron computed tomography was performed at the High Flux Isotope Reactor to evaluate the presence of carbon agglomerates in TRISO fuel kernel three-dimensionally. Additionally, resonance computed tomography was developed at the Spallation Neutron Source to spatially resolve uranium and gadolinium content in produced fuel kernels. In this presentation, the basics of both the attenuation-based and resonance-based computed tomography and their applications in TRISO fuel characterization will be presented. |
