In the Broader Approach (BA) activities, the International Fusion Energy Research Center (IFERC) project, the International Fusion Materials Irradiation Facility/Engineering Validation and Engineering Design Activities (IFMIF/EVEDA) project and the Satellite Tokamak project are implemented aiming at early realization of the fusion energy from 2007 to 2017. DEMO design activity has been conducted as joint work between EU and Japan, in order to establish DEMO design bases. In the DEMO R&D activities, following five R&D tasks related blanket materials and technology are carried out; R&D on RAFM steels as structural material, SiCf/SiC composites as a flow channel insert material and/or alternative structural material, advanced tritium breeders and neutron multipliers, and tritium technology relevant to the DEMO operational condition. Regarding the IFMIF/EVEDA Project, the validation test using EVEDA Lithium Test Loop (ELTL) was completed successfully in 2014 the end of October. Installation of the LIPAc injector and auxiliary equipment delivered by F4E has been done and the first proton beam extraction was successfully performed in November 2014.
