WebHeavy Water (D 2 O) or deuterium oxide is made up of two atoms of deuterium and one atom of oxygen. Deuterium is a stable isotope of hydrogen with double the mass of hydrogen due to presence of an extra neutron in its nucleus. ... Nuclear reactors that use heavy water can employ a form of uranium commonly found in nature (U-238) ... WebDeuterium–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 most efficient type of fusion for fusion devices.. Tritium, one of the reactants required for this type of fusion, is radioactive.In fusion …

WebTranscribed Image Text: o "Heavy water," deuterium oxide (D₂O), is sometimes used in nuclear reactors to slow or moderate the speed of neutrons associated with the fission process. Like ordinary water (H₂O), deuterium oxide dissociates into an anion and cation. D₂0(1) D¹(aq) + OD (aq) Kw = 8.913×10-16 at 20°C A.
