In Research Group for Corrosion Resistant Materials, we are conducting research on corrosion of metal materials used for nuclear facilities. If corrosion occurs, component and piping of the nuclear facility will degrade, which may cause through holes and cracks. Therefore, we are focusing on research on corrosion mechanism, development of the methods of corrosion prediction and/or prevention and development of simulation method and so on. For example; a study on corrosion of stainless steel in boiling nitric acid solution and numerical simulation of corrosion in fuel reprocessing plant environment, a study on corrosion of steels in high temperature pressurized water and effect of radiolysis in nuclear reactor environment. Through these research activities, we contribute to improving the reliability of nuclear facilities.
