Thermophysical properties are of critical importance to the successful demonstration of a molten salt reactor (MSR) as they establish some critical design constraints. This study focuses on the sodium and potassium-chloride (ClNaK) salt system. Many of these properties need to be understood to optimize models and for successful reactor operations. Volatility experiments are underway using thermal gravimetric analysis (TGA) that will elucidate the thermal stability of ClNaK salts. Viscosity is being developed by method of parallel plate utilizing a thermomechanical analyzer (TMA). Current density experiments performed using a modified geometric method, align well with literature values. For instance, initial measurements give a density of pure KCl and NaCl at 800°C of 1.41 and 1.44 g/cm3 which are within 5% of previously reported values. This talk will detail the development of the molten salt characterization techniques and the results found in the ClNaK system.
