Research Abstract

Flinak loop system Orosh2i-1 has been designed and constructed as the world’s first apparatus for performing experiments on separate recovery of hydrogen and heat under circulation condition of a molten salt cooled blanket system. Development and studies on a centrifugal pump for high temperature (>500 oC) Flinak, hydrogen sensor, hydrogen recovery module, hydrogen permeation barrier coating, anti-corrosion coating, hydrogen absorption and release properties in Flinak, etc. have been successfully advanced for establishment of a self-cooled molten salt blanket system with high inherent safety.
