As part of the development of risk assessment technologies for sodium-cooled fast reactor coupled to thermal energy storage (TES) system with sodium-molten salt heat exchanger (HX), simple evaluation of heat transfer performance using heat transfer coefficient formula is performed. And Computational Fluid Dynamics (CFD) thermal analyses by STAR-CCM+ with partial HX model are performed to develop evaluation technology. The performance evaluation technology of a HX between sodium and molten salt and the confirmation of heat transfer improvement measures effects is developed.

As part of the development of safety design technologies for sodium-cooled fast reactor coupled to thermal energy storage system with nitrate molten salt heat exchanger, we are considering optimization of heat exchanger type and measures to improve heat transfer. We have conducted Computational Fluid Dynamics analyses with the partial model of the selected heat exchanger type. In this presentation we present the heat transfer performance based on the analyses results.
