Fast Facts About Nuclear Fusion. Principal Energy Use: Electricity Form of Energy: Nuclear Fusion reactions power the sun and the stars. Nuclear fusion occurs when nuclei from two or more atoms are forced together (overcoming the Coulomb barrier*) and fuse to form a single larger nucleus, releasing lots of energy (by E = mc 2), usually in the form of fast moving neutrons.

Nuclear fusion

OverviewHistoryProcessIn starsRequirementsArtificial fusionConfinement in thermonuclear fusionImportant reactions

Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy. This difference in mass arises due to the difference in nuclear binding energy between the atomic nuclei before and after the reaction. Nuclear fusion i
