Storage of Hydrogen Isotopes on ZrCo and ZrNi

Abstract

The CANDU reactors representing a powerful tritium source in time. ICIT Rm. Valcea has developed a technology for the detritiation of the tritiated heavy water based on catalyzed isotopic exchange coupled with cryogenic distillation. Tritium will be removed from the tritiated water and will be necessary for the storage of it in the safe containers. The reference material is uranium because of the high storage capacity and its stability in time, but because of the radioactivity of this material, other material was tested. ZrNi and ZrCo was tested because there are promising materials for storage, supply and recovery of tritium.
