30/10/2002 Sixth ITER negotiation meeting (N4) : press release 


The sixth meeting ( N6) concerning the negotiations among the partners of the international project ITER (Canada, Japan, Russia, and European Union) has just ended to Rokkasho-Mura in Japan. Site assessment of Canadian site and Japanese site was undertaken. The last assessments concerning the two European sites (Cadarache in France and Vandellos in Spain) will be held in December.

The EU Delegation distributed to Participants copies of the technical dossier supporting the French site candidature. The EU delegation underlined the importance and the quality of Cadarache infrastructures as the best guarantee of the success of ITER construction.

The next meeting will be held in Barcelona on December 9-10 2002.

About 680 researchers representing 41 countries met in Lyon from 14 till 19/10/2002 during the 19-th international Conference on the Energy of Fusion.

Claudie Haigneré, french Minister in charge of research and new technologies made a welcome speech, underlining the importance for France of the works on the controlled fusion and in particular for the ITER project.

Mr le Haut Commissaire ŕ l'énergie atomique presented an overview of the fusion energy. Recent developments in Tore Supra have been described by Jean Jacquinot, head of "Département de Recherches sur la Fusion Contrôlée, CEA Cadarache"  (Jean Jacquinot's slideshow, 20 pages, PDF, 1425 Ko ).

02/08/2002 New world record  for Tore Supra. 
  Six hundred Megajoules injected, six hundred Megajoules extracted !

On July 30th 2002, the engineers and scientists of the Association Euratom-CEA have achieved a three and a half minutes long plasma discharge on Tore Supra, sustained by 3MW of current drive power, thus requiring to exhaust more than 600 Megajoules of thermal energy during the experiment. It establishes a new world record in this domain after the 280MJ discharges of 1996. Prior to the record discharge, a number of long pulse shots have been achieved, demonstrating the capability of Tore Supra to run long pulses on a regular basis.

The capability to run long pulse plasmas on a regular basis opens the way to explore new scientific questions in ITER relevant conditions like the aging of the toroidal limiter under thermal cycling, limiter erosion and hydrogen trapping (co-depostion), real time discharge control and performance optimisation (confinement and stability) through a set of feedback control systems.

This remarkable result has been obtained with the newly completed configuration of actively cooled plasma facing components which ensures that every square centimetre of the wall in front of the plasma is actively cooled. It is worth recalling that two years were needed for the European industry to complete the complex manufacturing of the 600 fingers which constitute the toroidal limiter of the project, each of them being composed of 21 tiles made of carbon fibre composite bonded to the copper base. The more than 12000 tiles have been individually controlled before final acceptance of the fingers. One and a half year was necessary to install the overall assembly, including the 5m in diameter limiter ring with a position accuracy of 1/10th of a millimetre to ensure an homogeneous distribution of the heat deposition.

This record value, very quickly achieved during the experimental campaign, is in no case a limit in performance. The range of accessible parameters has now to be explored in order to establish its actual capability. In principle, energies exceeding a gigajoule should be achieved by the overall assembly corresponding to discharge durations of hundreds of seconds.

A batch of record discharges !


The record discharge :  3mn 33s, 0.61 GJ
