Post-transient examination of performance of uranium silicide fuel and silicon-carbide composite cladding under reactivity-initiated accident conditions

•First transient testing of accident-tolerant fuel designs under transient nuclear heating reactivity-initiated accident conditions.•Claddings experienced dimensional changes but maintained primary rod-like geometries.•Elemental species diffusion from the U3Si2 fuel to the zircaloy cladding was obse...
