Deuterium–tritium fusion (sometimes abbreviated D+T) is a type of nuclear fusion in which one deuterium nucleus fuses with one tritium nucleus, giving one helium nucleus, one free neutron, and 17.6 MeV of energy. It is the best known fusion reaction for fusion devices.
Tritium, one of the reactants required for this type of fusion, is radioactive. In fusion reactors, a 'breeding blanket' made of lithium is placed on the walls of the reactor, as lithium, when exposed to energetic neutrons, will produce tritium.
