Because of their thermodynamic properties and their inherent safety heavy metal liquids such as lead or lead bismuth alloys are considered as promising coolants for future nuclear reactors. Therefore, compatibility of structural materials and coolant is a critical issue. Beside corrosion mechanical properties of structural material could be affected. In order to determine the effect of liquid metals on the mechanical properties of candidate materials for future reactors unique test setups have been built at SCK•CEN. In this internship the student should learn how to operate one of these setups, analyze the gained data and perform subsequent microstructural and fractographic analysis.
