Outline of Final Research Achievements

As a study on tritium permeation barrier in a fuel production and recovery system of a fusion reactor blanket, deuterium permeation measurements via liquid lithium-lead eutectic for erbium oxide coatings prepared on steel substrates have been performed to investigate hydrogen isotope permeation and chemical behaviors of tritium permeation barriers under liquid blanket environment. It was found that the permeation behavior via liquid lithium-lead was different from gas-phase permeation. In addition, the corrosion protection effect by the outer metal layer fabricated on erbium oxide coating has been indicated.
