Office of Science - ITER

International Thermonuclear Experimental Reactor (ITER) is a major international research project to demonstrate the feasibility of fusion energy.

This project is being designed and built by the ITER partners: the European Union, India, Japan, the People’s Republic of China, the Republic of Korea, the Russian Federation, and the United States. ITER is being constructed at Cadarache in southeastern France, with the European Union being the host party. 

ITER, which means “the way” in Latin, is one of the largest and most ambitious international scientific research projects ever conducted. Each member of the ITER Organization will contribute different key plant components; the goal in the long run is that each member will have the know-how to produce its own fusion energy plant.


What role does the United States have in ITER?

The United States is an equal, non-host partner responsible for about 9% of the construction cost of the international ITER Project.

How does Orano contribute to the ITER project?

Orano has been involved in this project since 2007 and supported US ITER with the design and equipment fabrication of the Tokamak Cooling Water System (TCWS). The TCWS is comprised of several cooling systems that will cool the fusion reaction by removing the heat formed during the fusion process. Orano completed the TCWS design and managed the fabrication and shipment of the TCWS’s pipe assemblies, pumps, heat exchangers, pressure vessels and filters to France.
