| Outline of Final Research Achievements |
While beryllium will be used as armor materials for ITER plasma-facing components, available information about beryllium effects on surface properties is still limited due to the precautions concerning beryllium handling. In this study, safety operating system for handling the beryllium-containing samples were constructed at first. Then, the microstructure and the deuterium retention property in beryllium and its deposition layers were systematically investigated. As a consequence, it is considered that Be seeding to plasma has a more dominant influence on microstructures and D retention in plasma-exposed W than He seeding.
