High temperature thermal hydraulics modeling of a molten salt: application to a Molten Salt Fast Reactor (MSFR)

Rubiolo, Pablo R.; Mauricio Tano Retamales; Véronique Ghetta; Julien Giraud

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 owing liquid fuel based on

a high temperature lithium uoride salt. A molten salt ow can be considered in many situations

as an incompressible ow. However, several phenomena intrinsic to a molten salt ow 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).
