| Abstract Scope |
Developments in the design of commercial fusion tokamak reactors are creating a demand for plasma-facing materials. These materials need to withstand extreme environments comprising of high temperatures (400- 600 °C), liquid metals (e.g. Li, eutectic PbLi), and high neutron dose, while limiting the magnetohydrodynamic (MHD) effects. Castable nanostructured alloy (CNA) steel and V alloys (e.g. V-4Cr-4Ti) are deemed the two leading structural materials for self-cooled liquid Li coolant concepts. The candidate alloys and steel-insulator-steel sandwich structures were exposed to high-temperature static liquid lithium. Their resistance to liquid lithium corrosion was characterized as well as their change in tensile and electrical insulating properties after exposure. |
