Overview Of Materials Research And Ifmif/Eveda Under The Broader Approach Framework

In parallel to the ITER program, the Broader Approach (BA) activities with three projects are being implemented by the European Union (EU) and Japan. Five research and development (R&D;) tasks, mainly on blanket-related materials, are being carried out as the DEMO R&D; program in the BA to establish key technologies required for the DEMO engineering design. The DEMO R&D; building was constructed in March 2010, and the installation of research equipment was completed in March 2011. As the BA DEMO R&D;, fabrication technology and/or characterization of reduced activation ferritic/martensitic steels, SiC/SiC composites, and the advanced neutron multiplier and advanced tritium breeder have progressed in Japan and the EU. In the Inter-national Fusion Materials Irradiation Facility (IFMIF)/Engineering Design and Engineering Validation Activities (EVEDA) project, engineering design and validations have progressed. The injector of the IFMIF prototype accelerator produced first beam successfully in May 2011 and will be delivered to the Rokkasho BA site in 2012. The commissioning of the EVEDA lithium test loop was completed in March 2011, and a lithium flow of 25 film thick at similar to 5 m/s was obtained.
