The main purpose of fusion fuel supply system is to store and supply hydrogen isotopes needed for operation of ITER and to provide the necessary infrastructure for short and long term storage of large amount of hydrogen isotopes. The storage of tritium as metal tritide on hydride forming metals or intermetallic compounds is recognized as the most reliable and safe method. Considering the advantages and disabvantages of several hydrogen isotope getter materials, the authors suggest the use of ZrCo on the basis of its ideal P-T-C characteristics and its non pyrophoricity. The authors also suggest the hydrogen isotope storage beds design appropriate to the fusion fuel supply system.
