| Abstract Scope |
Alumina scales formed on the surface of blanket materials are being explored as electrical insulators and liquid metal corrosion barriers for future fusion reactor designs. While the high temperature compatibility of alumina scales and liquid metals such as eutectic PbLi, Sn and Li was previously studied, the combined effect of neutron irradiation and high temperature liquid metal exposure on the stability and microstructure of the alumina layer has received limited attention in the literature. In the present work, a first of a kind, liquid tin rabbit capsule containing pre-oxidized FeCrAl alloys was irradiated in the High Flux Isotope Reactor at a target temperature of 400 °C for 10 days. Post-irradiation examination of the exposed specimens was conducted. The impact of neutron irradiation on the stability and microstructure of the alumina layer will be discussed with the results of multi-scale microstructural characterization techniques |
