Abstract

High-temperature near-IR absorption spectroscopy was used to study the dissolution of UO₂ in molten MgCl₂, CaCl₂, and AlCl₃ melts. The study reveals that UO₂ is most soluble in molten AlCl₃, followed by the melt of MgCl₂. The solubility of UO₂ in molten CaCl₂ is too small to be measured with optical spectroscopy. This strong dependence of the solubility on the cations of the melts was rationalized by the use of the Flood-Forland-Grjotheim thermodynamic cycle.
