Interactions between fusion materials R&D and other technologies

The importance of interactions between fusion materials research and development (R&D) and other technologies is emphasized to make attractive and realistic fusion technology integration activities. The focuses are on: (1) materials design and processing, (2) safety issues relating to materials and (3) material performance evaluation methodologies, including 14 MeV neutron source utilization for fusion material R&D. As typical examples, material design activities on reduced activation ferritic steels, vanadium alloys and SiC/SiC composite materials are provided. The safety assessment of reactor systems and reactor design code consideration including prediction methodologies of materials performance are also discussed.
