ITER

Definition

ITER, which stands for International Thermonuclear Experimental Reactor, is a major international research and engineering project aimed at demonstrating the feasibility of nuclear fusion as a large-scale and carbon-free source of energy. This project involves a collaborative effort among multiple countries to design and build a tokamak, a device that uses magnetic fields to confine plasma at extremely high temperatures, allowing for the fusion of hydrogen isotopes. The goal of ITER is to prove that fusion can be achieved sustainably and economically, paving the way for future fusion power plants.
