Abstract

Hydrogen recovery unit is developed for the molten salt loop Orosh2i-1. Pure Ni was selected as hydrogen permeation material due to its industrial maturity of fabrication technology and good compatibility with molten salt in fusion reactor condition. No significant degradation of hydrogen permeability of the pure Ni during the fabrication process. Advanced hydrogen permeation materials, such as Pd, V, Nb, and Ta, maintaining higher hydrogen permeability are also discussed to develop more compact hydrogen recovery systems.
