The EU-Japan Broader Approach Activities

1. The EU-Japan Broader Approach Activities SOFT 2006 ( Warsaw, 11-15 September) Shinzaburo Matsuda Japan Atomic Energy Agency

2. Origin of Broader Approach Activities Joint Declarationat theMinisterial Meeting for ITER (Moscow,28 June 2005) ---- ITER Site,Contribution, and EU-JA Joint Paper(Attachment to Joint Declaration) Joint implementation of broader approach activities in the territory of the non-Host, on a time frame compatible with the ITER construction phase. + Funding contribution: 46bnY, and 339mnE + Candidate projects IFMIF(EVEDA and/or Facility) ITER research center(s): including - computational simulation center for fusion science - a center for remote experimentation Fusion power plant technology co-ordination center, including a center for international design activities for the demonstration reactor A new plasma experimental device (Satellite Tokamak)

3. The Broader Approach project(s) will be chosen by the non-Host from the above-mentioned projects. Projects which are not included in the above list could be chosen at the initiative of the non-Host provided that they contribute to a rapid realization of fusion energy and the Host and non-Host jointly decide to undertake them. ******************************************* Background of Fusion Energy R&D in Japan and in EU Japan: JAEC Report “Technical Feasibility of Fusion Energy (May 2000)” JAEC report “Strategy of the Fusion Research and Development (Oct. 2005)” Start of BA Discussion between EU and JA: July 21, 2005 at Garching Since then, numerous number of legal and technical experts meetings and governmental negotiation meetings have been held to develop agreed plans on BA activities.

5. The BA Activities comprise the following three Projects 1) Engineering Validation and Engineering Design Activities for the International Fusion Materials Irradiation Facility (IFMIF/EVEDA) 2) International Fusion Energy Research Center (IFERC), a)A DEMO Design and, R&D coordination Center b)A Computational Simulation Center c)An ITER Remote Experimentation Center 3) Satellite Tokamak Programme Upgrade of JT-60 Tokamak to an advanced superconducting tokamak (JT-60SA)

11. Modification of JT-60U (JT-60SA) for BA and National Programs • Enhanced flexibility in aspect ratio (A=2.6-3.1) and plasma shape. • High power heating/current-drive system, 41MW for 100 s, will be prepared. • High beta steady-state operation (N~4, fBS~70%) for DEMO and high density ELMy H-mode operation (ne~9x1019m-3) for ITER are planned.

12. Summary Three Projects are identified suitable for Broader Approach Activities between EU and Japan. They are: IFMIF/EVEDA, IFERC and JT-60SA Possible schedule for initial and subsequent procedure for signature and ratification of the Agreement will be fixed quite soon. Establishment of Steering Committee, Nomination of Implementing Agency, Project Leader, and Project Team Members have to be made in near future. Preparatory work has been started such as discussion on IFERC, review of conceptual design of JT-60SA, IFMIF/EDEDA design, etc. The BA Activities are open to other ITER members and their participation will be welcome.
