Abstract

High-density U-6wt%Mo/Al and U-10wt%Mo/Al dispersion fuel samples have been irradiated by heavy ions in order to simulate fission fragments. The dose was set to 1017Ion/cm², which corresponds to a low burn-up as compared to in-pile irradiation. The aim of the irradiation is to investigate the cause of the interdiffusion layer, which develops between the U-Mo fuel particles and the surrounding Al-matrix. Post irradiation analysis has shown an interdiffusion layer due to irradiation by heavy ions. This interdiffusion layer has similar properties as found by reactor irradiation.
