IFMIF/EVEDA: Adjustment of Scope and Recent Technical Achievements

The International Fusion Materials Irradiation Facility (IFMIF) aiming at generating a material database for DEMO and future fusion power plants is commonly understood by the European Union and Japan as one of the pillars toward DEMO, and IFMIF Engineering Design and Engineering Validation Activities (EVEDA) have been conducted since mid 2007 in the framework of the Broader Approach Agreement. So far the main efforts have been focused on validation work to provide information necessary for engineering design. In 2010, the scope of the project was revised to set priority on the validation of an accelerator prototype while extending the duration up to mid 2017, while the other activities will be completed in mid 2013 as the primary plan, and the goal of engineering design has been modified to accomplish the Intermediate Report. In 2011, several outcomes of validation of major components have been achieved: (1) first operation of an ion injector has been conducted, (2) a lithium test loop was constructed and commissioned, and (3) test pieces for fission reactor irradiation have been manufactured. This paper summarizes the status of all activities and expected outcomes of the IFMIF/EVEDA project.
