| Abstract Scope |
Two dimensional (2D) and three dimensional (3D) laboratory-based X-ray microscopy has been used to characterize a variety of materials related to nuclear energy, including fuel (U-10Zr), cladding (SiC/SiC composites, zirconium alloys), and structural components (graphite). 3D X-ray imaging of nuclear fuels is difficult due to the inherent mass attenuation coefficients of high-Z materials and is limited to a fuel thickness of a few millimeters at most. However, sub-micrometer scale 3D X-ray microscopy can be employed to characterize nuclear fuel samples of the appropriate size. 2D X-ray microscopy can also be employed to characterize high aspect ratio fuel samples to supplement other characterization techniques. While the imaging of fuel is not trivial, the imaging of cladding and structural materials is more straightforward. This presentation will give an overview of the techniques used to image nuclear energy materials using laboratory-based X-ray microscopy at Idaho National Laboratory’s Irradiated Materials Characterization Laboratory. |
