As part of the development of safety design technologies for sodium-cooled fast reactor coupled to thermal energy storage system (SFR with TES) with sodium–molten salt heat exchanger, the present study investigates the chemical reactivity between liquid metallic sodium and nitric acid-based molten salt, assuming boundary failure in heat exchangers. This is a report on the results of fundamental experiment on the chemical reactivity between sodium and molten salt.
