Abstract: This work is devoted to study of changes of structure and chemical composition in corrosion areas of the chosen candidate alloy, Nickel 201, for components of a LS-VHTR. The material was annealed at 1013K/10h/vacuum and at 1000°C/24h/Ar before corrosion tests. The annealed material was studied after its exposure to the molten mixture of 60 mol. % LiF + 40 mol. % NaF at the temperature of 1013K. The exposition was carried out in a quasidynamic regime, which simulates real circulation of the coolant (a mixture of molten salts) in the piping. The structure of the alloy was studied by SEM. Severe corrosion damage was observed in grain boundaries.
