tokamak reactor

A tokamak reactor is a device designed to generate energy through nuclear fusion, the process that powers the sun. It uses powerful magnetic fields to confine and control hot plasma—a superheated, ionized gas—where hydrogen isotopes fuse to release vast amounts of energy. This confinement prevents the plasma from touching the reactor walls, maintaining the extreme conditions needed for fusion. Unlike nuclear fission, fusion produces less radioactive waste and uses abundant fuel sources, making it a promising, sustainable source of clean energy. The tokamak's complex magnetic system is central to achieving and sustaining the high temperatures necessary for fusion reactions.
