WebThe fission of lithium to helium (and tritium) by Cockroft and Walton in 1932 was the first artificial fission reaction, in this case induced by proton bombardment: Li-7 + proton ==> 2He-4 + 17 MeV The more significant reaction today is: Li-6 + neutron ==> He-4 + H-3 (tritium) + 4.8 MeV WebAt the temperature created by fission in the core, tritium and deuterium can undergo thermonuclear fusion without a high level of compression. The fusion of tritium and deuterium produces a neutron with an energy of 14 MeV—a much higher energy than the 1 MeV of the neutron that began the reaction. This creation of high-energy neutrons, rather ... maillages association

WebTritium is also produced as a fission product in nuclear weapons tests and in nuclear power reactors, with a yield of about 0.01%. That is, about one atom of tritium is produced per 10,000 fissions. Each year a large commercial nuclear power reactor produces about WebThe main fuels used in nuclear fusion devises are deuterium and tritium, both heavy isotopes of hydrogen. The Deuterium (D) – Tritium (T) reaction has the largest cross section (in other words, the probability of a reaction to take place) and also the largest Q-value (the released energy of a reaction) of all varieties of fusion reactions. WebThe most promising source of tritium seems to be the breeding of tritium from lithium-6 by neutron bombardment with the reaction. which can be achieved by slow neutrons.
