Recently, there has been an increased interest in molten salts as coolants for nuclear plants. Despite the potential for increased corrosion rates in the containment vessel, molten salts minimize the risk of explosions because they do not need to be pressurized. Fluoride salts are the preferred candidates for a coolant material, but the associated expenses and safety hazards make them unattractive for prolonged utilization. Chloride salts offer a safer and more cost-effective alternative but can be highly corrosive. Therefore, careful consideration is required in the material selection process of the containment vessel. In this project, iron-based and nickel-based alloys were exposed to a ternary molten eutectic salt at 700°C. The post-test coupons were characterized with optical microscopy and scanning electron microscopy (SEM). The viability of the chloride salt as a coolant material will be discussed.
