ITER, which stands for International Thermonuclear Experimental Reactor, is a major international project aimed at demonstrating the feasibility of nuclear fusion as a large-scale and carbon-free source of energy. Located in France, ITER brings together 35 nations, including the European Union, United States, China, India, Japan, and South Korea, to collaborate on this groundbreaking research. The project focuses on creating a plasma that can sustain fusion reactions, similar to the processes that power the sun. By achieving this, ITER hopes to pave the way for future fusion power plants that could provide a sustainable energy solution for the world.
