In this study, the Born-Mayer potential was used to calculate the physicochemical properties of the FLiNaK ternary eutectic. The commonly used Fumi and Tosi parameters were here superseded by those obtained ab initio to push the model accuracy closer to its suppositional limit. Density, local structure data, self-diffusion coefficients, viscosity, thermal conductivity and heat capacity were calculated. Comparison with reference data, both theoretical and experimental, reveals the performance of the Born-Mayer potential for obtaining the properties of the FLiNaK. In addition, new data on the local structure dynamics is presented by the calculation of the ion pair lifetimes.
