| Abstract Scope |
Heavy liquid metals (HLM) and molten salts (MS) are important candidates for the next generation of nuclear reactor coolants. Understanding corrosion of materials exposed to these coolants while they are simultaneously subjected to radiation typically requires extensive post-experiment analysis, which only provides snapshots of the process. In this talk, we will present an overview of in situ thickness measurements of model materials under HLM and MS corrosion and simultaneous proton irradiation in the irradiation-corrosion experiment (ICE). Results are obtained using proton-induced x-ray emission (PIXE) spectroscopy, which continuously measures x-ray emissions from the beam spot and yields in situ observations of bulk changes in the irradiated region over time. The in-situ PIXE estimates of the corrosion depth in the irradiation-corrosion region will be compared with ex-situ measurements of the cross section via microscopy. |
