Deuterium has a number of commercial and scientific uses. These include: Deuterium is used in heavy water moderated fission reactors, usually as liquid D2O, to slow neutrons without the high neutron absorption of ordinary hydrogen. This is a common commercial use for larger amounts of deuterium. In research reactors, liquid D2 is used in cold sources to moderate neutrons t…
