Abstract
The proper high-level waste container materials in China are still under research. In the consideration of availability of carbon steel and low-alloy steel, the corrosion behaviors of four kinds of commercial steels in simulated groundwater of Beishan, a candidate place for the geological disposal of high level waste in china, were investigated (which is the preselected area for building geologic disposal repository to store high-level nuclear waste) groundwater in the presence of different immersion time, temperature and oxygen content. The morphology and chemical compositions of corrosion products were investigated by means of Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and Energy Disperse Spectroscopy (EDS). The corrosion behaviors of these four steels were compared, and the most potential candidate steel based on the present immersed corrosion test results was recommended.
