FLiNaK compatibility studies with Inconel 600 and silicon carbide

SiC/SiC Composites Technology Gap Analysis for Molten Salt Reactors

“…Most of the current out-of-core experiments use FLiNaK as a surrogate for FLiBe in thermal/fluid experiments to avoid toxicity/safety issues with beryllium handling[93]. Table5.2 shows a summary of measurements and estimations of some of the major thermophysical properties of interest (melting point, boiling point, density, heat capacity, volumetric heat capacity, thermal conductivity, and viscosity at the conditions noted) for the candidate coolant salts and other coolants for comparison[91,[95][96][97][98][99]. The salt 8NaF-92NaBF 4 is shown as a reference for the historical candidate coolant salt for the Molten Salt Breeder Reactor at ORNL in the 1970s.…”
