Organisation history
The initial international cooperation for a nuclear fusion project that was the foundation of ITER began in 1978 with the International Tokamak Reactor, or INTOR, which had four partners: the Soviet Union, the European Atomic Energy Community, the United States, and Japan. However, the INTOR project stalled until Mikhail Gorbachev became general secretary of the Communist Party of the Soviet Union in March 1985.  Gorbachev first revived interest in a collaborative fusion project in an October 1985 meeting with French President François Mitterrand, and then the idea was further developed in November 1985 at the Geneva Summit with Ronald Reagan.Preparations for the Gorbachev-Reagan summit showed that there were no tangible agreements in the works for the summit. However, the ITER project was gaining momentum in political circles due to the quiet work being done by two physicists, the American scientist Alvin Trivelpiece who served as Director of the Office of Energy Research in the 1980s and the Russian scientist Evgeny Velikhov who would become head of the Kurchatov Institute for nuclear research. The two scientists both supported a project to construct a demonstration fusion reactor. At the time, magnetic fusion research was ongoing in Japan, Europe, the Soviet Union and the US, but Trivelpiece and Velikhov believed that taking the next step in fusion research would be beyond the budget of any of the key nations and that collaboration would be useful internationally.Dr. Michael Robert, who is the director of International Programs of the Office of Fusion Energy at the US Department of Energy, explains that, 'In September 1985, I led a US science team to Moscow as part of our bilateral fusion activities. Velikhov proposed to me at lunch one day his idea of having the USSR and USA work together to proceed to a fusion reactor. My response was 'great idea', but from my position, I have no capability of pushing that idea upward to the President.' This push for cooperation on nuclear fusion is cited as a key moment of science diplomacy, but nonetheless a major bureaucratic fight erupted in the US government over the project. One argument against collaboration was that the Soviets would use it to steal US technology and expertise. A second was symbolic and involved American criticism of how the Soviet physicist Andrei Sakharov was being treated. Sakharov was an early proponent of the peaceful use of nuclear technology and along with Igor Tamm he developed the idea for the tokamak that is at the heart of nuclear fusion research. However, Sakharov also supported broader civil liberties in the Soviet Union, and his activism earned him both the 1975 Nobel peace prize and internal exile in Russia, which he opposed by going on multiple hunger strikes. The United States National Security Council convened a meeting under the direction of William Flynn Martin to discuss the nuclear fusion project that resulted in a consensus that the US should go forward with the project.
This led to nuclear fusion cooperation being discussed at the Geneva summit and release of a historic joint statement from Reagan and Gorbachev that emphasized, "the potential importance of the work aimed at utilizing controlled thermonuclear fusion for peaceful purposes and, in this connection, advocated the widest practicable development of international cooperation in obtaining this source of energy, which is essentially inexhaustible, for the benefit of all mankind." For the fusion community, this statement was a breakthrough, and it was reinforced when Reagan evoked the possibilities of nuclear fusion in a Joint Session of Congress later in the month.As a result, collaboration on an international fusion experiment began to move forward. In October 1986 at the Reykjavik Summit, the so-called 'Quadripartite Initiative Committee' (Europe through the Euratom countries, Japan, USSR, and the USA) was formed to oversee the development of the project. The year after, in March 1987, the Quadripartite Initiative Committee met at the International Atomic Energy Agency (IAEA) headquarters in Vienna. This meeting marked the launch of the conceptual design studies for the experimental reactors as well as the start of negotiations for operational issues such as the legal foundations for the peaceful use of fusion technology, the organizational structure and staffing, and the eventual location for the project. This meeting in Vienna was also where the project was baptized the International Thermonuclear Experimental Reactor, although it was quickly referred to by its abbreviation alone and its Latin meaning of 'the way'.Conceptual and engineering design phases were carried out under the auspices of the IAEA. The original technical objectives were established in 1992 and the original Engineering Design Activities (EDA) were completed in 1998. An acceptable, detailed design was validated in July 2001 to complete the extended EDA period, and the validated design then went through a Design Review that began November 2006 and concluded in December 2007. The design process was difficult with arguments over issues such as whether there should be circular cross sections for magnetic confinement or 'D' shaped cross sections. These issues were partly responsible for the United States temporarily exiting the project in 1998 before rejoining in 2003.At this same time, the group of ITER partners was expanding, with China and South Korea joining the project in 2003 and India formally joined in 2005.There was a heated competition to host the ITER project with the candidates narrowed down to two possible sites: France and Japan. Russia, China, and the European Union supported the choice of Cadarache in France, while the United States, South Korea, and Japan support the choice of Rokkasho in Japan. In June 2005, it was officially announced that ITER would be built in the South of France at the Cadarache site. The negotiations that led to the decision ended in a compromise between the EU and Japan, in that Japan was promised 20% of the research staff on the French location of ITER, as well as the head of the administrative body of ITER. In addition, it was agreed that 8% of the ITER construction budget would go to partner facilities that would be built in Japan.On 21 November 2006, at a ceremony hosted by French President Jacques Chirac at the Élysée Palace in Paris, an international consortium signed a formal agreement to build the reactor. Initial work to clear the site for construction began in Cadarache in March 2007 and, once this agreement was ratified by all partners, the ITER Organization was officially established on 24 October 2007.In 2016, Australia became the first non-member partner of the project. ITER signed a technical cooperation agreement with the Australian Nuclear Science and Technology Organisation (ANSTO), granting this country access to research results of ITER in exchange for the construction of selected parts of the ITER machine. In 2017, Kazakhstan signed a cooperation agreement that laid the groundwork for technical collaboration between the National Nuclear Center of the Republic of Kazakhstan and ITER. Most recently, after collaborating with ITER in the early stages of the project, Canada signed a cooperation agreement in 2020 with a focus on tritium and tritium-related equipment.The project began its five-year assembly phase in July 2020, launched by the French President Emmanuel Macron in the presence of other members of the ITER project.
