This thesis is dedicated to the investigation of the structural destabilisation of UO2 single crystal. Irradiations with 470-keV Xe, 500-keV Ce and 500-keV La ions (with corresponding ion range of Rp 85 nm and range straggling of Delta Rp _ 40 nm according to SRIM calculation) have been performed to investigate the destabilisation of UO2 single crystals induce by (i) the radiation damage effects due to the nuclear stopping process of a fission fragment at the end of their trajectories (ballistic contribution) and by (ii) the incorporation of a fission product at high concentration (chemical contribution). The energies and masses of bombarding ions were deliberately chosen so that they would have very similar projected range in UO2 in order ...
