Corrosion of construction materials in KCl–LiCl–UCl3 melts containing metallic zinc

Corrosion resistance of VDM Alloy С-4, Hastelloy G-35 and ХН62М (KhN62M) nickel based alloys, and AISI316L type steel was studied in alkali chloride melts containing uranium (III) chloride and metallic zinc. These alloys are considered as prospective construction materials in pyrochemical reprocessing of spent nitride nuclear fuels including decladding fuel rods by liquid zinc dissolution process. Rates of corrosion of these materials were determined at 550 °C.
