MagneticConfinementFusionReactors

Magnetic Confinement Fusion Reactors aim to harness the energy released when light atomic nuclei fuse, mimicking the process that powers the sun. This is achieved by heating a plasma of deuterium and tritium isotopes to extreme temperatures (millions of degrees Celsius) and confining it within powerful magnetic fields, typically in doughnut-shaped tokamaks or twisted stellarators. The international ITER project, Commonwealth Fusion Systems (CFS), and Helion Energy are prominent players in this field. The technology is currently in advanced research, with large-scale experimental facilities and prototype reactors under construction. In 2021, the Joint European Torus (JET) achieved a record 59 megajoules of sustained fusion energy, while CFS's SPARC project demonstrated its powerful REBCO high-temperature superconducting magnets could generate fields strong enough for net energy gain. Unlike nuclear fission, fusion promises virtually limitless fuel (from water), no long-lived radioactive waste, and inherent safety without risk of meltdown.
