Heavy ion irradiation has been proposed for discriminating UMo/Al specimens which are good candidates for research reactor fuels. Two UMo/Al dispersed fuels (U-7 wt%Mo/Al and U-10 wt%Mo/Al) have been irradiated with a 80 MeV (127)I beam up to an ion fluence of 2 x 10(17) cm(-2). Microscopy and mainly Xray diffraction using large and micrometer sized beams have enabled to characterize the grown interaction layer: UAl(3) appears to be the only produced crystallized phase. The presence of an amorphous additional phase can however not be excluded. These results are in good agreement with characterizations performed on in-pile irradiated fuels and encourage new studies with heavy ion irradiation.
