The advanced ceramic fuel development program is exploring revolutionary ceramic fuels with the potential of “game-changing” impact on reactor operation & response to beyond design scenario. Key properties of advanced fuels include high thermal conductivity, oxidation resistance, high temperature mechanical properties, and thus improved accident tolerance. Composite ceramic fuels possess distinct advantages to fulfill these key requirements. In this talk, recent advancements of using field-assisted sintering technologies, specifically spark plasma sintering (SPS), in fabricating advanced fuels and engineering fuel matrix will be reviewed including graphene-based UO2 composite fuels, large-grained fuel doped by oxide additive and the high uranium density fuel. The fuel behaviors are characterized with the focus on the thermal-mechanical properties and the correlation among the SPS process – microstructure control – thermal mechanical properties variation are established. The potential application of the composite fuels as advanced fuel design with enhanced accident tolerance will be discussed.
