| Abstract Scope |
Predicting the complex multiscale, multiphysics behaviour of nuclear materials requires simulating problems exhibiting very tight coupling between different physical phenomena. Such strong coupling of physical phenomena is especially demonstrated in the Molten Salt Reactors (MSR) posing a challenge in reactor design and development as hitherto insignificant effects become conspicuous. One such behaviour is the corrosion of structural materials by the molten salt. Corrosion is an electrochemical process driven by the thermodynamics and kinetics of the reactions and the material microstructure significantly affects the corrosion behaviour. Corrosion modelling at mesoscale requires coupling thermodynamic equilibrium calculations with the phase field method for microstructural evolution. A new application, Yellowjacket, is being developed and it is built on the Idaho National Laboratory's Multiphysics Object Oriented Simulation Environment (MOOSE). This work describes the recent progress towards development of Yellowjacket and presents some preliminary results demonstrating simulation capabilities of interest to the development of MSRs. |
