Ion beam techniques (Rutherford backscattering (RBS) with and without the channelling effect technique, resonance scattering on 16O with high energy He beams, elastic recoil detection analysis (ERDA), SIMS and nuclear reactions such as H(15N, alpha gamma)12C for H detection have been used extensively and successfully in recent years to investigate surfaces and surface-near layers of materials of importance for nuclear energy. These materials include the nuclear fuels UO(2) and UN, the tailor-made borosilicate glasses and the special ceramics (for example, SYNROC) for solidification and safe long-term storage of high level radioactive waste. In this latter area, ion beam techniques have significantly improved the understanding of the mechanisms and kinetics of corrosion in water. Ion beam techniques have also been applied to introduce foreign atoms and to modify the surfaces of these materials, and additional ion beam techniques were subsequently used to analyse the surface changes and modifications. This article presents a review of these largely unpublished activities and points out some of the important progress achieved recently, for example, on the mechanism of polygonisation of UO(2).
