Abstract
The corrosion of Hastelloy S, Hastelloy X, Haynes 230, Hastelloy N, Hastelloy G35 and Hastelloy C2000 alloys was studied in KCl–AlCl3 melts at 550 °С. The rates and the mechanisms of corrosion of the studied materials were determined. The processes taking place during the interaction between alloys and chloroaluminate melts were investigated.
Highlights
Fast neutron energy reactors with molten salt coolant are related to a whole new generation of safe nuclear reactors where both uranium and thorium nuclear fuel can be used
The introduction of nuclear power plants based on molten salts is constrained by a number of problems; the most important of which is the need to develop new or improve existing structural materials, preserving stability in very aggressive conditions of high molten media
This work is aimed at a comprehensive study of the interaction of high-temperature alloys Hastelloy S, Hastelloy X, Haynes 230, and corrosion-resistant alloys Hastelloy N, Hastelloy G35 and Hastelloy C2000 with chloroaluminate melts
