Abstract Scope |
The application of uncertainty quantification and propagation (UQ & UP) in thermodynamic modeling has been a topic of interest in the last couple of decades in the CALculate PHAse Diagrams (CALPHAD) community. This is because a quantified understanding of the uncertainty of phase boundaries and thermodynamic properties based on the available data and selection of models in a database has large intrinsic value. One example is that through UQ & UP one can identify more effectively the chemical regions of interest that require additional measurements in order to improve prediction reliability while minimizing the number of experiments This presentation will use the open source ESPEI software to demonstrate how UQ & UP can serve in the advancement of the Molten Salt Thermal Properties Database − Thermochemical (MSTDB−TC) designed to support development of molten salt nuclear reactors, particularly as they relate to corrosion processes. |
