Abstract Scope |
To make our Molten Salt Thermal Properties Database-Thermochemical (MSTDB-TC) relevant for molten salt reactor safety analysis, it is important to include the reciprocal iodide salt systems. The iodide salts are volatile and radiologically hazardous, and thus their behavior under accident conditions are important to understand. As necessary, we reassessed iodide with chloride or fluoride reciprocal system thermodynamic models using a self-consistent methodology within the CALPHAD approach. In this presentation, we present the results of the analyses and the thermochemical properties of the various pseudo-binary systems including but not limited to LiI-LiF, BeI2-BeF2, UI3,UI4-UF3,UF4, LiI-LiCl, NaI-NaCl, MgI2-MgCl2, and UI3,UI4-UCl3,UCl4. Using these pseudo-binary models, we were able to extrapolate to related pseudo-ternary and pseudo-quaternary systems. |
