Photos: Building the World’s Largest Fusion Reactor

The International Thermonuclear Experimental Reactor (ITER) project is constructing the world's largest magnetic fusion device in France. This collaborative effort involves 35 nations aiming to demonstrate the viability of nuclear fusion as a large-scale, carbon-free energy source. The project is recognized as one of the most extensive and costly scientific endeavors undertaken globally. Construction of the reactor, a tokamak design, is progressing with significant components being assembled. The ITER Organization, headquartered in Cadarache, France, oversees the project's development and integration of contributions from its member states. The goal is to achieve sustained fusion reactions, mimicking the process that powers the sun, to generate clean electricity.
