Deuterium is another isotope of hydrogen. However, their … See more 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 … See more Tritium is an isotope of hydrogen, which allows it to readily bind to hydroxyl radicals, forming tritiated water (HTO), and to carbon atoms. Since tritium is a low energy beta emitter, it is not dangerous externally (its beta particles are unable to penetrate the skin), … See more Web2. TRITIUM FORMATION In general, tritium is formed in the fission event that follows neutron absorption by parent nuclides. Differing reactor types form tritium in different ways and in different amounts: in a pressurized water reactor (PWR), tritium is formed by neutron absorption by the boric acid (neutron poison) in the water; in
