Abstract.  IFMIF has been pushed forward so far under the Implementing Agreement on Fusion Materials Development in the frame of IEA collaborating agreements. The KEP (Key Element technology Phase) was successfully completed in 2002, and the two subsequent years were devoted to follow-up activities and preparation for the EVEDA phase. In the past five years, major accomplishments have been made in each of the four areas of IFMIF development, i.e. a) accelerator system, b) target system, c) test facility and d) design integration and conventional facilities. These outcomes are compiled in the Comprehensive Design Report and will also be briefly reported in this presentation. In the next phase (which will last six years), the content of EVEDA as described in the CDR has been modified and fabrication and tests of 1:1 prototypes of the low energy part of the IFMIF accelerator are planned. The present prototype accelerator concept consists of ECR ion source, Radio Frequency Quadrupole, matching section and the first tank of the Drift Tube Linac and will be tested with beam. After completion of the EVEDA mission, the use of the prototypes is foreseen in the construction of the final IFMIF accelerator or as spare parts for cost reduction. In the target system area, a model loop with its lithium inventory 1/3 of the IFMIF full scale will be constructed and tested for more than 10000 hours. As for the test facility tasks in EVEDA, mock-ups of the test assembly will be fabricated and the intended performance will be demonstrated, including reliability tests of the rig assemblies in existing fission reactors. The IFMIF EVEDA activity will be conducted under the ITER-BA framework as a Bilateral Agreement between Japan and Europe. In this framework, Japan and EU, each will contribute 8% of the ITER construction cost and approximately 20% of this fund will be allotted to EVEDA. Participation of other parties in the BA is foreseen. The incorporation of the expertise of other countries will be beneficial for the IFMIF project, including IFMIF users.
