28 June 2005: a home at last

Ten years ago, on 28 June 2005, a home was found for ITER. In Moscow, where ministerial-level representatives of the ITER Members had convened, a consensus had at last been reached:  the International Thermonuclear Experimental Reactor planned by China, the European Union, Japan, Korea, Russia and the United States (India would join six months later) would be located in Cadarache, a locality in the village of Saint-Paul-lez-Durance, some 75 kilometres north of Marseille, France.

Cadarache was a familiar name for the fusion community worldwide. Home to one of the French Atomic Energy Commission's (CEA) largest research centres, it hosts its magnetic fusion department and the Tore Supra superconducting tokamak. In the last round of a two-year negotiation, the Cadarache site—proposed by the European Union—was unanimously chosen for the world's largest fusion facility.

A little less than twenty years after the design activities for the project had been launched, the Moscow decision marked the end of a long, difficult and sometimes painful process.

It all began in the spring of 2001 when the ITER Final Design Report — the detailed blueprint of the installation — was being finalized for submission to the ITER Council.

A group of Canadian industrialists and academics who were interested in being part of the project (Canada, as a nation, was not a Member) made a first proposal in April 2001 for a site in Clarington, Ontario, home to the Darlington nuclear power plant, some 20 kilometres east of Toronto. "For the first time since the project's inception in 1985, the name 'ITER' was associated with a precise location," remembers Jean Jacquinot, one of the experts who participated in the negotiations. "The Canadian proposal lent credibility to the project."

Experts in Cadarache had undertaken "site studies" as early as the mid-1990s. In 2000, these studies were reactivated and updated and, in 2003, a formal proposal was made by the European Union to the other Parties.

The year before, year, Spain had proposed a site at Vandellòs, on the Mediterranean shore south of Tarragona (also the location of a nuclear power plant), and Japan proposed Rokkasho-Mura, where a uranium enrichment plant, nuclear waste storage installation and used fuel reprocessing plant cohabit on a peninsula 14 kilometres long.

One site in Canada, two in Europe, one in Japan — that was three too many... In Europe, the issue was solved on 26 November 2003 when the twenty-five Research ministers of the member states voted unanimously for Cadarache. As compensation, Spain would host the soon-to-be-established European Domestic Agency, responsible for the European in-kind contributions to the project. As for the Canadian consortium, it decided to withdraw from the ITER negotiations the following month.

The year 2003 was drawing to an end and the ITER Members still had a decision to make.

An optimistic joint communique, however, proclaimed: "The six Parties have reached a strong consensus on a number of points. We have two excellent sites for ITER, so excellent in fact that we need further evaluation before making our decisions based on consensus."

Reaching consensus would require another 18 months. In order to break the gridlock, a "Broader Approach" program was devised that included the construction of a materials research installation for fusion, "a satellite machine" for ITER, a computing centre for fusion science and a centre for remote experimentation — something for which Europe had always advocated. The Broader Approach installations would offer scientific and economic "compensation" for the party that would not host the machine.

Additional meetings were organized in Vienna in February 2004 and again in June, politicians on both sides entered the game, and partisan newspaper columns were published ... some fair, some less so. On both sides, the spring of 2005 was rife with sibylline declarations, allusions, hints...

On 28 June the long-awaited decision was at last made official in a joint public announcement by Janez Potočnik, the European Commissioner for Science, and Noriaki Nakayama, the Japanese Minister of Science and Technology. "I wish to say that today Japan is both sad and happy," said Nakayama. "However, this project is so important that we have decided to overcome our grief and change it into joy."

Two days later, French President Jacques Chirac was in Cadarache to celebrate the momentous event. No one had "won," no one had "lost." The ITER Members had demonstrated their capacity to overcome difficult odds and to imagine a solution that was acceptable to all

And so ten years ago, the ITER Members laid the foundation for the kind of spirit that continues to carry forward this unique collaboration for science.
