| Abstract Scope |
Understanding the response of materials to simultaneous irradiation and corrosion is vital for the development of structural alloys for the next generation of nuclear reactors and their coolants. Irradiation-corrosion experiments with new coolants, such as heavy liquid metals and molten salts, are difficult to conduct and often only yield data during post-experimental analysis. This means that multiple experiments are needed to obtain information about the kinetics of the corrosion process under irradiation, and that each data point has experiment-specific uncertainties connected to it. Particle-induced x-ray emission spectroscopy (PIXE) is supposed to fill this gap using continuous measurements of x-ray intensities from the sample and the corrosive medium during irradiation. We will present a quantitative interpretation of Fe sample thickness changes due to simultaneous LBE corrosion and 4 MeV-proton irradiation. Additionally, we will also discuss early attempts to obtain similar PIXE data with molten salt as the corrosive medium. |
