| heavy water |
Water containing a significantly greater proportion of heavy hydrogen (deuterium) atoms to ordinary hydrogen atoms than is found in ordinary (light) water. Heavy water is used as a moderator in some reactors because it slows neutrons effectively and also has a low cross-section for absorption of neutrons.

Heavy water or deuterium oxide (D 2 0) is a natural form of water used to lower the energy of neutrons in a reactor. It is heavier than normal water by about 10 per cent, and occurs in minute quantities (about one part heavy water per 7,000 parts water).

| heavy water |
Water in which the hydrogen is composed of over 99 percent deuterium atoms. The neutron in the deuterium nucleus allows this type of water to slow, or moderate, neutrons from fissioning uranium, permitting a sustained chain-reaction in reactors using natural uranium as fuel. See CANDU, Deuterium, and Moderator.

| heavy water |
Water with a high proportion of deuterium (one proton and one neutron) instead of hydrogen (with one proton, but no neutron in the nucleus).
