Interactions between fusion materials R&D and other technologies

The importance of interactions between fusion materials research and develo pment (R&D) and other technologies is emphasized to make attractive and rea listic fusion technology integration activities. The focuses are on: (1) ma terials 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 an d SiC/SiC composite materials are provided. The safety assessment of reacto r systems and reactor design code consideration including prediction method ologies of materials performance are also discussed. (C) 2000 Elsevier Scie nce B.V.
