| Abstract Scope |
Radiation has recently been shown to decelerate corrosion in molten salts at reactor-relevant temperatures. Because corrosion in liquid lead proceeds largely via the same mechanisms - selective dissolution - it is hypothesized that this same effect will occur in liquid lead at similar temperatures. In this talk, we will report the first results showing the changes in kinetics and mechanisms of various steels exposed to 650C liquid lead irradiated by protons, in a thin-foil simultaneous corrosion/irradiation facility on an ion accelerator. Dry ion polishing, critical to resolving percolating voids formed during corrosion, is used to fully preserve features for subsequent SEM, TEM, 4D-STEM, and APT analyses to reveal how concurrent irradiation affects corrosion in this potential Generation IV nuclear reactor technology. |
