Abstract : This article focuses on the speciation of molten fluoride mixtures based on ThF 4 and UF 4 actinides used in molten salt reactors. The local structure of molten AF-MF 4 systems (A=Li + , Na + , K + ; M= Th 4+ , U 4+) was studied in situ by combining measurements by high temperature X-ray absorption spectroscopy and molecular dynamics simulations. In the molten state, 20°C

Keywords : EXAFS Molecular dynamics high temperature molten salt reactors speciation actinides
