High temperature thermal hydraulics modeling of a molten salt: application to a molten salt fast reactor (MSFR)
Abstract
An overview of the ongoing eorts 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).
