| Abstract Scope |
Safe utilization of molten salt reactors (MSRs) currently requires additional measurements of the molten salts’ thermophysical properties. We have previously utilized a modified transient-hotwire method with a needle probe to measure the thermal conductivity of fluoride and chloride salts. Degradation of the original device led us to develop a new probe with a lower production cost, better thermal conductivity, higher corrosion resistance, minimized electromagnetic interference, and a higher temperature rating due to the implementation of an aluminum nitride core (replacing alumina) and Inconel sheath (replacing Nickel-200). This needle probe device is paired with a new through-hole crucible design and compared to theoretical models to test fluoride, chloride, and actinide-bearing salt compositions, providing a more cost effective and flexible method of contributing thermophysical data. |
