Broader Approach Activities toward Fusion DEMO Reactors IT/E-2

IAEA 21st Fusion Energy Conference

(Chengdu 　 17th October, 2006 )

Origin of Broader Approach Activities

• Joint Declaration at the Ministerial Meeting for ITER　 (Moscow,28 June 2005) ---- ITER Contribution, and it’s Site are decided.

• 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

Start of BA Discussion between EU and JA started in July 21, 2005 at Garching. Since then, a number of legal and technical experts meetings and negotiation meetings ha

ve been held to develop agreed plans on BA activities. Agreement has been made by the negotiators on Oct. 2006.

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)

Article 25 of the Broader Approach Activities

“In the event that any other party to the ITER Agreement expresses its intension to participate in a project of the Broader Approach Activities, the Project Leader concerned shall, after consultation with the Project Committee, submit to the Steering Committee a proposal concerning the terms and conditions of the participation of that party in such project. The Steering Committee shall decide on the participation of that party upon the proposal of the Project Leader, and subject to the approval of the Parties following their internal procedures, may conclude agreements and arrangements with that party on such participation.”

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 Signature of the Agreement will be 　 fixed quite soon. Formal start of the BA activities is expected in a first half of 2007.• Establishment of Steering Committee, Nomination of Implementing Agency, Project Leaders, and Project Team Members have to be made in near future.• Preparatory work has been started such as for discussion on IFERC, on conceptual design of JT-60SA, IFMIF/EDEDA.• The BA Activities are open to other ITER members and their participation will be quite welcome.
