Abstract Scope |
Before advanced nuclear reactor concepts come online to provide carbon-free energy sources, nuclear materials and fuel forms must be studied extensively for commercial qualification. While destructive examinations have been historically performed, recent developments in micro X-ray Computed Tomography (XCT), have enabled nondestructive three-dimensional (3D) examination of irradiated Tristructural isotropic (TRISO) coated fuel particles and TRISO compacts. In this work, imaging of fresh and irradiated individual TRISO particles, as well as imaging of irradiated TRISO compacts, is discussed with emphasis on the sample preparation, radiation shielding, and methodology necessary for the imaging of highly radioactive TRISO samples. The implementation of custom 3D image reconstruction techniques that allow for additional information from both the uranium-based kernel and the carbon-based buffer layers is also presented. Lastly, a discussion on quantitative data extraction and its future use in TRISO fuel analysis is included in this work. |
