Species Chemistry and Electrochemical Separation in Molten Fluoride Salt
… products and corrosion products in molten FLiNaK salt (46.5LiF-11.5NaF-42KF mol%) which is the surrogate of the primary coolant candidate FLiBe (67LiF-33BeF2, mol%) for FHR. The main objective is to investigate the electrochemical behaviors of fission products and corrosion products in …

Decommissioning considerations for molten salt type reactors
… systems were used: one for the synthesis of FLiNaK salt and the other for the remelting and drainage of residue FLiNaK from a Hastelloy-C276 segment. The results of these experiments have demonstrated that FLiNaK salt, given contact with atmospheric moisture, tends to change in condition over …

Accelerated atomistic prediction of structure, dynamics and material properties in molten salts
… prototypical Flibe (66.6%LiF-33.3%BeF2), and Flinak (46.5%LiF-11.5NaF-42%KF). Predictions include thermophysical and transport properties such as bulk density, thermal expansion coefficient, bulk modulus, and diffusivity, which were compared to available experimental data.

Evaluating Fluoride Molten Salt Thermophysical Properties with Transient Grating Spectroscopy
… measure the thermal conductivity of fluorides (FLiNaK). Results show a flat to slightly increasing thermal conductivity as a function of temperature (0.7086 + 0.0002 ⋅ T(oC) +/- 0.08 W/m-K). In addition to thermal conductivity, sound speed data as a function of temperature (2998 – 1.24 ⋅ T(oC) …

Separation and Properties of La₂O₃ in Molten LiF-NaF-KF Salt
… In this study, the La₂O₃-LiF-NaF-KF (La₂O₃-FLiNaK) system is used to demonstrate impurity separation in molten fluoride salt. Since lanthanum oxide needs to be dissolved in the fluoride molten salt and studies in this field are still not complete, the solubility of lanthanum oxide in FLiNaK …

Natural convection of molten salt in laterally heated and top cooled vertical cylinders
… characteristics within the molten salt FLiNaK (Prandtl number = 16) in a vertical three-dimensional cylindrical geometry are numerically studied. The cylinder is laterally heated with an isothermal cooling at the top and an insulated bottom. The effect of the Rayleigh number is …
