| Abstract Scope |
The Molten Salt Thermal Properties Database-Thermochemical (MSTDB-TC) has been under development since 2019 and now includes components for all envisioned uranium-plutonium fueled systems and key fission products. The consistent set of Gibbs free energy relations are provided in a format usable in commercial and open-source equilibrium codes as well as in the MOOSE-coupled Thermochimica code that allows use with various MSR modeling and simulation codes. The curated database content is the result of extensive evaluation of reported experimental values of heat capacities; heats of formation, mixing and transition; and phase equilibria as well as use of in-house measurements performed to fill critical gaps in salt system information. The effort has also required the development of new instrumental methodologies/techniques and analyses for determining accurate values. This presentation will provide an overview of the current database, highlight some new methodologies, and examples of applications of the database. Instructions for accessing both the Thermochemical and Thermophysical databases are available at mstdb.ornl.gov. |
