A Collaborative National Center for Fusion & Plasma Research


What is ITER?

ITER is a large international fusion experiment aimed at demonstrating the scientific and technological feasibility of fusion energy.

ITER (Latin for "the way") will play a critical role advancing the worldwide availability of energy from fusion — the power source of the sun and the stars.

To produce practical amounts of fusion power on earth, heavy forms of hydrogen are joined together at high temperature with an accompanying production of heat energy. The fuel must be held at a temperature of over 100 million degrees Celsius. At these high temperatures, the electrons are detached from the nuclei of the atoms, in a state of matter called plasma.

U.S. Contributions to ITER

U.S. Contributions to ITER is a DOE Office of Science Major Item of Equipment (MIE) project consisting of procurement of hardware (including supporting R&D and design), assignment of personnel (U.S. engineers and scientists) to the ITER site in Cadarache, France, and in Field Teams in the ITER parties, and cash contributions to the ITER Organization for the U.S. share of common expenses such as personnel infrastructure, assembly and installation. All U.S. ITER project activities will be managed by the U.S. ITER Project Office The project will be accomplished through a collaboration of DOE laboratories, universities, and industry.

International ITER

An unprecedented international collaboration of scientists and engineers has performed needed research and development and designed a burning plasma experiment called ITER. The fusion power produced by ITER will be 10 times greater than the external power delivered to heat the plasma.

The United States has joined the other ITER partners in negotiations for construction of this project, whose mission is to demonstrate the scientific and technological feasibility of fusion power. These deliberations could lead to the operation of ITER around the middle of the next decade.

ITER Partners are The People's Republic of China, the European Union (represented by Euratom), India, Japan, the Republic of Korea, the Russian Federation, and the United States of America. The device will be built at Cadarache located near Marseille in the Provence-Alpes_Cote d'Azur region of southeastern France.
