The Behavior of Fission Products in Molten Fluoride Reactor Fuels

Compositional transferability of deep potential in molten LiF–BeF2 and LaF3 mixtures: prediction of density, viscosity, and local structure

“…[3][4][5][6][7][8][9][10][11] It is suggested that the thermophysical properties of molten fluorides are significantly affected by impurities, 12 so the impurity content should be strictly controlled in the application of MSRs. Lanthanide fluorides (LnF 3 ), as main nuclear fission products, 13 dissolved in molten Flibe, may affect its thermophysical properties, thereby affecting the thermal energy storage and transfer performance of carrier salts. Therefore, studying the thermodynamic properties of molten Flibe + LnF 3 mixtures is critical to the design and development of MSRs, and the transport behavior of lanthanide products in molten Flibe is also essential to the daily operation of MSRs and the pyroprocessing of spent fuels.…”
