As part of the development of safety design technologies for sodium-cooled fast reactor coupled to thermal energy storage system with sodium–molten salt heat exchanger, we are considering the chemical reactivity between liquid metallic sodium and nitric acid-based molten salt, assuming boundary failure in heat exchangers. In this report, we present the fundamental experiment planning and the status of the present study for the cited reaction.
