Thermodynamic properties and phase diagrams of fluoride salts for nuclear applications

Molten salts database for energy applications

“…Globally, the agreement is nearly perfect [88] among all values with the exception of Williams correlation, showing a rising curve when plotted all data in a X (% BeF 2 ), Y (log η) graph. For T > 1050, although viscosity becomes almost constant, data are near parallel (Fig.…”

“…When available, possible differences have been checked by using different compositions of the same salt by the same work or author, in order to analyze its behavior in molar terms and the differences among the temperature range of measurement. Phase diagrams and useful properties have been also recently reviewed by Beneš and Konings [80,88] for nuclear fission applications, including critical discussion of recent values and measurements of FLiBe, FLiNaK and NaFNaB.…”

Molecular dynamics simulation of diffusion and viscosity of liquid lithium fluoride

“…LiF, as an important component in the mixtures, which has a rock-salt structure under ambient conditions [3], has been found to own many advantages over other alkali halides and ionic crystals, such as good chemical stability, optically transparent insulator, and high melting point. As the coolant and carrier in the MSR [4,5], LiF improves the transport properties of the eutectic which composed by the thorium fluoride salt and carrier [6,7], enhances the energy efficiency of MSR [8], and reduces the possibility of incidents and makes a safer environment [9,10]. Moreover, LiF has potential applications as a pressure transmitting medium and a pressure calibrant in static measurements [11,12] and shock impression.…”

Evidence of dynamical local scale distribution heterogeneities in CsF-AF (A=Li, Na, K and Rb) molten salts

“…19 An important factor in A c c e p t e d M a n u s c r i p t 3 these developments is the availability of high purity materials inert toward molten fluorides (boron nitride, pyrolitic boron nitride and glassy carbon) for the design of new sample containers. Nuclear magnetic resonance (NMR) spectroscopy, 20,21 extended X-ray fine absorption spectroscopy, 22,23 Raman spectroscopy, 24 electrochemistry, 25,26 thermodynamics studies, 27,28,29 etc. have thus beneficiated a new impulse.…”
