Abstract Scope |
Impurities in as-cast metallic nuclear fuels can significantly impact microstructure formed during fuel processing, and ultimately in-reactor performance. Thus, understanding the influence of such impurities on the microstructure of nuclear fuels, including the composition and isotopic abundances of impurity phases are important in development of material processing steps that improve fuel foil quality and in turn their irradiation performance. Here, impurities in an as-cast, low-enriched metallic uranium fuel alloyed with 10 wt% molybdenum (U10Mo) are studied. In order to address when, where, and how impurity elements lead to second phase precipitation in castings, detailed compositional and isotopic analysis was performed using atom probe tomography |
