| Abstract Scope |
Molten salts are potential heat transfer and storage fluids for advanced nuclear reactor designs and concentrated solar power. Material properties, especially thermal conductivity, of most molten salts are not yet known with sufficient accuracy for commercial applications. The high temperatures required, the corrosivity, and the electrical conductivity of molten salts make many existing thermal conductivity measurement techniques difficult to apply and prone to error. To overcome this, the latest iteration of a modified transient-hot-wire needle probe measures is capable of measuring above 750 °C. Experimentally measured temperature data is fit to a multi-layer thermal quadrupoles model to calculate the thermal conductivity. The thermal conductivity of eutectic MgCl2-NaCl between 500 °C and 800 °C was measured with uncertainties between 10% and 20%. |
