FABRICATION AND EXPERIMENT STUDY OF THE THERMAL CONVECTION LOOP FOR MULTI-PURPOSE MOLTEN SALT EXPERIMENTS

抄録

In MSR, liquid fuel uses molten salt, usually a eutectic mixture with a low melting point and a high boiling point. At high temperatures, molten salt has heat transfer properties similar to water. Molten salt has a strong tendency to corrode materials, its properties are easily changed because it reacts sensitively to oxygen and moisture. In the reactor, molten salt circulates in an airtight structure with a metallic material and is exposed to nuclear fission reactions, corrosion reactions, and transmutation reactions, producing various by-products. By-products make to change and accumulate the component and composition of molten salt fuel over time. The associated thermal physics and thermal chemicals properties can be changed. This study fabricated the thermal convection loop for the multi-purpose molten salt experiments. The molten salt experiment was performed using a multi-purpose molten salt experimental loop to evaluate the corrosion and thermodynamic properties of the molten salt.
