An overview of the ongoing efforts in the area of the thermal hydraulics modeling of a Molten Salt Fast Reactor (MSFR) is presented. The MSFR employs a flowing liquid fuel based on a high temperature lithium fluoride salt. A molten salt flow can be considered in many situations as an incompressible flow. However, several phenomena intrinsic to a molten salt flow pose unique challenges (radiative heat transfer, volumetric heat source, strong neutronics feedbacks, etc.). To study some of these phenomena and to improve current Computational Fluid Dynamics (CFD) models an experimental facility called SWATH (Salt at WAll: Thermal ExcHanges) will be built as part of the European project SAMOFAR (2015-2019).
Résumé
Une description des efforts en cours dans le domaine de la modélisation thermo hydraulique du réacteur à sel fondu rapide (Molten Salt Fast Reactor, MSFR) est présentée. Le MSFR utilise un combustible nucléaire liquide basé sur un sel fondu de type Lithium Fluorure (LiF). Dans la plupart des conditions d’opération normale ou accidentelle un sel fondu peut être considéré comme étant un fluide incompressible. Néanmoins la modélisation précise de plusieurs phénomènes intrinsèques au sel fondu pose un important défi (transfert radiatif, source volumétrique de puissance, contreréactions neutroniques, etc.). Dans le cadre du projet Européen SAMOFAR (2015-2019), la plateforme expérimentale SWATH (Salt at WAll : Thermal ExcHanges) est actuellement en construction. Cette plateforme permettra d’étudier certains de ces phénomènes et ainsi d’améliorer la précision des modèles de type Computational Fluid Dynamics (CFD) utilisés pour prédire les écoulements du sel combustible.
