ITER’s main goal is to achieve a plasma capable of producing at least 10 times as much fusion energy as the energy consumed. Inside the tokamak, plasma reaching 150 million °C is kept suspended within a magnetic field using superconducting magnets. This technology aims to pave the way for an energy source that is carbon-free, long-lasting, and highly safe.
The campus is not limited only to the tokamak reactor. It offers a fully integrated science and engineering ecosystem with cryogenic facilities, power conversion infrastructure, tritium processing systems, material testing laboratories, and advanced control centers. Construction and assembly processes are pushing the limits of modern engineering through millimetric tolerances, heavy lifting operations, and complex system integrations.
ITER does not aim to move directly into energy production; instead, it takes on the role of a critical intermediate stage proving that fusion is scientifically and technically possible. The knowledge gained from the project will form the foundation of future commercial fusion power plants (DEMO reactors).
With its scale, multinational cooperation model, and technological depth, ITER Tokamak and Research Campus is positioned as a historic turning point in the transition to a fossil-fuel-free energy future.
