As the activities of Grants-in-Aid for Scientific Research from MEXT, the effects of tritium water and organic tritium on the confinement materials of fusion reactors have been studied. The corrosion and permeation of tritium on the metals and organic compounds have been studied. For the tritium water processing technology, the characteristics of the chemical exchange column have been studied. These R&D studies allow us to examine the safety of fusion reactors.
