|Abstract:||The described research work is motivated by the common interest of SKB (Svensk Kärnbränslehantering AB), INE (Institute for Nuclear Waste Disposal) and ITU (Institute for Transuranium Elements) concerning the mechanistic understanding of the corrosion properties of nuclear waste systems. The systems investigated are thin films of UO2+x and ThO2 produced by the sputter deposition technique at ITU and reference materials. Characterisation methods for the films and references are X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and Atomic Force Microscopy (AFM). Raman microprobe spectroscopy was evaluated as additional examination method for the thin films and surface secondary phases, which can build up during corrosion experiments. The solubility of selected thin film samples was compared to corresponding powder material.|
