Study on Sodium Nanofluid for Fast Reactor (1) Concept of Sodium Nanofluid

摘要

The sodium cooled fast reactor is developed at present. Liquid sodium which possesses the excellent thermal hydraulics properties is used for the coolant, but it has high chemical reactivity with water or oxygen. We created an idea which suppress the chemical reactivity of liquid sodium. Nanometer-size metallic particles suspend in liquid sodium and an atomic interaction utilizes between nanoparticle and surrounding sodium atom for suppression of chemical reactivity. Physical properties which relate the chemical reactivity changed by the atomic interaction. These changes also were verified by the experiments. From these results the chemical reactivity of liquid sodium would be suppressed.
