| Outline of Final Research Achievements |
In this study, irradiation effects on hydrogen isotope permeation have been investigated using ceramic coatings for tritium permeation barrier in fusion reactor fuel systems.
Iron ion irradiation as a simulation of neutron irradiation was performed for the coatings followed by microstructural analysis and deuterium permeation measurements. It was found that the balance between displacement damage and damage recovery by heating largely affected on deuterium permeation behaviors. As for gamma-ray irradiation, the world-first increase in deuterium permeation under gamma-ray irradiation was detected. The increase rate depended on dose rate and test temperature. The coated samples showed a smaller increase rate, suggesting that ceramic coatings would assume not only a role as a tritium permeation barrier but also as a protection layer for irradiation.
