As part of the ongoing effort to convert high power research and test reactors from high-enriched to low-enriched fuels, uranium-molybdenum alloy fuel dispersed in aluminum matrix (UMo-Al dispersion fuel) has become the leading candidate fuel. One of the primary barriers to using this fuel type is the formation of an interaction layer between the UMo fuel and Al matrix. This interaction layer causes swelling of the fuel plate and becomes amorphous under irradiation, leading to breakaway swelling due to fission gas accumulation. A thorough understanding of the behavior of this interaction layer under irradiation is imperative in order to prevent or delay this undesirable behavior from occurring. TEM samples of the UMo-Al interaction layer from next to the fuel and close to the Al matrix were selected and examined at the IVEM-Tandem in-situ irradiation facility in order to characterize their behavior under irradiation. Results of this study are presented here.
