| Abstract Scope |
Significant strides in the development of the Molten Salt Thermal Properties Database – Thermochemical (MSTDB-TC) will allow the extensive thermodynamic description of salt systems relevant to the design, operation, and regulation of molten salt reactors (MSRs). Given the essential material compatibility requirements for MSR designs, MSTDB-TC provides open access to reliable thermodynamic models useful for prediction of multi-component phase equilibria and other complex processes like corrosion. Chromium in structural materials presents a particular challenge for its formation of halide compounds in salt systems. In this presentation, new phase equilibria measurements for the Cr-U(III) chloride pseudo-binary and Na-Mg-U(III) chloride pseudo-ternary systems will be reported, and their use in the development of predictive phase equilibria for the Na-K-Mg-U(III) chloride salt system is demonstrated. Additionally, the temperature and composition space favorable to inhibit corrosion with chromium is explored. |
