Progress in Coupling Computational Thermodynamics and Computational Fluid Dynamics to Support Molten Salt Reactor Applications

Abstract

Progress on the development of multi-physics capabilities by coupling computational fluid dynamics and computational thermodynamics codes for Molten Salt Reactor applications. This work is part of the SAMOSAFER project and is intended to support on capability development with applications related to reactor safety, including over-heating and under-cooling scenarios. A one-way coupling scheme between OpenFOAM and Thermochimica is demonstrated through a solidification process of the MSFR, where phase accountancy and influence of solid salt formation are shown. The JRCMSDB is used as input to thermodynamic calculations and its applications expected in future studies. This is the first step of a long-term plan for a two-way coupling and this paper presents progress towards this goal.
