“…These issues could be resolved by applying advanced model-based image reconstruction methods with beam-blocking corrections. A previously developed software for analyzing XCT images of particle fuel forms was used to analyze each compact (Helmreich et al 2020b). This software determined the centroid positions of each kernel relative to the body of the compact, as well as the volume of each kernel.…”

MiniFuel compacts containing 20 individual tristructural isotropic (TRISO)-coated fuel particles were characterized to provide supporting preirradiation characterization data. The preirradiated characterization data supports irradiation capsule design and safety analysis, as well as downstream postirradiation examination (PIE) for a planned MiniFuel irradiation to explore high particle powers. The analysis included dimensional inspection, x-ray radiography and tomography, as-fabricated defect fraction analysis, and a matrix impurity analysis.

“…Figure 1-1 shows larger matrix-only zones in the core, which were a result of the thicker overcoating applied to the DTF particles to help space them out axially (Hunn, Trammell, and Montgomery 2011). Recent progress in x-ray computed tomography and image analysis (Helmreich et al 2018) make it possible to determine the particle distribution in the AGR-3/4 compacts more accurately. This will be pursued to refine the comparison of expected particle count with actual count, and may provide more confidence to the use of the optical analysis of compact diameter to determine radial deconsolidation volume.…”
