Description
Summary:A study of the irradiation behaviour of uranium silicide and other related inter-metallic uranium compounds is presented. This study was motivated by the recent discovery that U 3Si 2 undergoes a crystalline to amorphous transformation during irradiation. Such information renders a previously developed fuel swelling model based on the crystalline state of U 3Si 2 invalid. This is of particular significance since low enriched U 3Si 2 dispersion fuels are widely used in research reactors. While such a finding does not alter the well established, stable and benign behaviour of U 3Si 2 during irradiation, it does indicate that a different interpretation of that behaviour is required.
