Tritium breeding
WebTritium is a fast decaying radioactive isotope of hydrogen with very scarce natural reserves. Supply Naturally occurring tritium is scarce. Techniques for breeding tritium from lithium … Tritium is most often produced in nuclear reactors by neutron activation of lithium-6. The release and diffusion of tritium and helium produced by the fission of lithium can take place within ceramics referred to as breeder ceramics. The production of tritium from lithium-6 in such breeder ceramics is possible with neutrons of any energy, though the cross section is higher when the incident neutrons have lower energy, reaching more than 900 barns for thermal neutrons. This is an
