“…Thus, the data quality is extremely sensitive to the integrity of the crystallographic lattice order at the surface of the sample and to oxidation [2]. While conventional sample preparation methods are widely used in materials science, they often do not lead to quality electron backscattered patterns needed for characterization of the nuclear materials [3]. Due to challenges associated with handling radiological specimens, rapid oxidation of the specimens, and "artifacts" (high number of defects, precipitates and/or porosities) [3][4][5][6][7].…”

Thus, the Focused Ion Beam (FIB) glazing technique [1,4,6] has been used and optimized for EBSD collection for this fuel type.…”

Great effort worldwide has been invested in replacing highly enriched uranium (HEU) fuel with lowenriched uranium (LEU) fuel in nuclear plants, in the frame of safeguarding nuclear material and promoting the proliferation resistance [1]. A monolithic U-Mo fuel type is being developed at Idaho National Laboratory for this purpose. This study focuses on the characterization of fresh and irradiated monolithic U-Mo fuel specimens to understand the effect of irradiation on the initial texture. Understanding, controlling and monitoring texture evolution under irradiation is important to evaluate material properties, as texture can affect up them up to 20-50% (e.g. Young's modulus, Poisson's ratio, strength ductility, toughness, thermal expansion, and magnetic-electrical properties) [2].

“…3 While conventional sample preparation methods are widely used in materials science, they often do not lead to quality electron backscatter patterns needed for the characterization of nuclear materials. 4 This has been related by many authors to the challenges associated with handling radiological specimens, their rapid oxidation, and artifacts in such samples (e.g., high number of defects, precipitates and/or porosities). 4,5,6,7,8 EBSD, however, can be an invaluable technique to evaluate microstructural evolution during fabrication and after irradiation at the required mesoscale for model and simulation.…”

It also provides important information on grain structure necessary to understand irradiation effect, such as grain subdivision.…”
