ITER

Definition

ITER (International Thermonuclear Experimental Reactor) is a large-scale international project aimed at demonstrating the feasibility of nuclear fusion as a viable and sustainable energy source. It seeks to replicate the processes that power the sun, harnessing fusion reactions to produce vast amounts of energy without the long-lived radioactive waste associated with traditional fission reactors. The project is significant for its potential to revolutionize energy production and contribute to solving global energy challenges.
