Abstract Scope |
Molten salt reactors (MSRs) potentially provide many unique benefits. LiF-NaF-KF (m% 46.5-11.5-42 - FLiNaK) and NaF-ZrF<sub>4</sub> (m% 53-47) are model MSR salts - the former salt is used as a heat transfer coolant and for thermal solar energy storage applications while the latter salt has been used as a fuel carrier and primary coolant. Knowledge of the atomic structure of the liquid salt is important for understanding the origin of the material’s physical and chemical properties. This study will discuss the molten salt structure data of both the fluoride salts as a function of temperature using high-energy x-ray scattering experiments that were conducted at Beamline 28-ID-D at NSLS-II, Brookhaven National Lab. Interatomic potentials molecular dynamics (IPMD) simulation results will also be presented and compared with experiments through the predicted pair distribution functions and coordination numbers at multiple temperatures by using LAMMPS. |
