• Corrosion behavior of a simulated high level radioactive waste glass in humic acid solution was studied. The elemental depth profile of the glass near the surface was measured by using Rutherford backscattering spectrometry (RBS). In the spectra, some peaks associated with multivalent elements such as Zr and Fe increased with the leaching time, showing that these elements accumulated near the glass surface in pure water. From the observed peak areas of Zr and Fe and from the energy shift of the Si edge, the thickness of the layer was estimated to be several tens nanometer. In the presence of the 100 ppm humic acid, on the other hand, no apparent peaks were observed possibly due to the formation of water-soluble metal complexes. Additionally, the dissolved ion concentration was determined by ICP-AES. Also, the humic acid was characterized by particle induced X-ray emission (PIXE) and by cation exchange capacity measurement.
