°ÄÃÅÁùºÏ²Ê¸ßÊÖ

As signatories to the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Agreement, the °ÄÃÅÁùºÏ²Ê¸ßÊÖ collaboration Members China, the European Union, India, Japan, Korea, Russia and the United States will share in the cost of project construction, operation and decommissioning, and also share in the experimental results and any intellectual property generated by the project. Twenty years of collaborative research experiments are planned on the machine.

Europe* is responsible for the largest portion of construction costs (45.6 percent); the remainder is shared equally by China, India, Japan, Korea, Russia and the United States (9.1 percent each). The Members contribute very little monetary contribution to the project: instead, nine-tenths of contributions are delivered to the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization in the form of completed components, systems or buildings. In this way, the scientific and industrial fabric in each Member is prepared for the step after °ÄÃÅÁùºÏ²Ê¸ßÊÖ collaboration—the conception and realization of the type of prototype fusion reactor that will demonstrate industrial-scale fusion electricity within this half of the century. For all Members, the benefits of participation are significant: by contributing a portion of the project's costs, Members benefit from 100 percent of the scientific results and all generated intellectual property.

Each Member has created a Domestic Agency to fulfil its procurement responsibilities to °ÄÃÅÁùºÏ²Ê¸ßÊÖ. These agencies employ their own staff, have their own budget, and contract directly with industry. Communication between the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization and the Domestic Agencies is facilitated by state-of-the-art collaborative CAD design tools, integrated project teams for specific components or projects, and video conferencing. The working language for the project is English.

Taken together, the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Members represent three continents, approximately 40 languages, half of the world's population and 73 percent of global gross domestic product. In the offices of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization and the Domestic Agencies, in laboratories and in industry, literally thousands of people are working toward the success of °ÄÃÅÁùºÏ²Ê¸ßÊÖ.

The °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization has also concluded non-Member technical cooperation agreements with Australia (through the Australian Nuclear Science and Technology Organisation, ANSTO in 2016); Kazakhstan (through Kazakhstan's National Nuclear Center in 2017), and Canada (2020).

*Update September 2023: The nations participating in °ÄÃÅÁùºÏ²Ê¸ßÊÖ include the 27 European Union countries plus China, India, Japan, Korea, the Russian Federation, and the United States. Whereas Switzerland and the United Kingdom (pre-Brexit) had been participating in the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Project through Euratom, the status of both nations in relation to Euratom has changed. Switzerland currently has the status of a "non-associated third country" in Euratom while negotiations on an association agreement continue; as such, it is considered by Europe to be a non-participating member in °ÄÃÅÁùºÏ²Ê¸ßÊÖ construction. The United Kingdom announced in September 2023 that it will no longer pursue an association agreement with Euratom, but that it will seek to continue and enhance its international partnerships, including with °ÄÃÅÁùºÏ²Ê¸ßÊÖ. For the present, the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Project is honouring any existing contracts with UK and Swiss citizens and companies, but not concluding new contracts.
