Abstract Scope |
Several coolants are considered for next-generation nuclear reactors, including heavy liquid metals (HLMs), such as Pb and Pb-Bi eutectic (LBE). The progression of corrosion in materials subjected to HLM corrosion and irradiation simultaneously is poorly understood and difficult to observe. Data for studies conducted in radiation-corrosion environments can typically only be collected post-experiment, merely providing snapshots of the process. The irradiation-corrosion experiment (ICE) III was designed to expose thin metal foils to LBE and proton irradiation to mimic reactor conditions and provide better insight into coupled irradiation-corrosion effects under these conditions. In addition to results from post-experimental analysis of pure Fe exposed to LBE and 4 MeV protons, we will present new in situ elemental measurements taken during the experiment via proton induced X-ray emission (PIXE) spectroscopy, potentially allowing us to continuously monitor the progression of corrosion. |
