Heavy water is water containing a higher-than-normal proportion of the hydrogen isotope deuterium, either as deuterium oxide, D2O or ²H2O.  Pure heavy water is not radioactive. It is about 11% denser than water, but otherwise, is physically very similar to water.  Relatively pure heavy water was produced in 1933, soon after the discovery of deuterium, the stable heavy isotope of hydrogen. With the discovery of nuclear fission in late 1938, and the need for a neutron moderator that captured few neutrons, heavy water became an important component of early nuclear energy programs during World War II (1939-1945).  Heavy water is an essential component in the design of some nuclear reactors, either for generating electric power or for producing nuclear-weapons isotopes, such as plutonium-239. Most contemporary enriched-uranium nuclear reactors use normal "light water" (H2O) for neutron moderation.
