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 [..]

Water that contains 2H, rather than 1H. Heavy water is about 11% denser than ordinary water.

Deuterium oxide, D2O; water containing two deuterium atoms instead of the two light hydrogen atoms. Natural water contains one deuterium atom per 6,500 molecules H2O. D2O has a low neutron absorption [..]

Water containing significantly more than the natural proportion (1 in 6500) of heavy hydrogen (deuterium) atoms to ordinary hydrogen atoms. Heavy water is used as a moderator in some nuclear reactors.

(Also known as deuterium oxide.) Water composed of oxygen and deuterium.

Water containing significantly more than the natural proportions (one in 6,500) of heavy hydrogen (deuterium, D) atoms to ordinary hydrogen atoms. Heavy water is used as a moderator in some reactors because it slows down neutrons effectively and also has a low probability of absorption of neutrons.

Heavy water is water where the hydrogen atoms are deuterium atoms. Heavy water is D2O.

Water containing an elevated concentration of molecules with deuterium ("heavy hydrogen") atoms.

Water in which all the hydrogen

Water containing significantly more than the natural proportion (one in 6, 500) of heavy hydrogen (deuterium atoms) to normal hydrogen atoms. Heavy water is used as a moderator in some reactors because it slows down neutrons effectively.

Water containing a large portion of “heavy” hydrogen, or deuterium (a hydrogen isotope with one extra neutron), which is used in nuclear reactors. Highly Enriched Uranium (HEU)

Water used as a cooling medium in a CANDU nuclear reactor; The hydrogen atoms that make up the water have an atomic weight of 2 due to the presence of a neutron in the nucleus.

A molecule of water contains two atoms of hydrogen and one of oxygen. Most water comprises of hydrogen/oxygen but a small percentage is composed of another hydrogen isotope, deuterium and oxygen. Deut [..]

The isotopic compound of Hydrogen of mass 2 (Deuterium) with Oxygen. (From Grant & Hackh's Chemical Dictionary, 5th ed) It is used to study mechanisms and rates of chemical or nuclear reactio [..]

water in which all the hydrogen atoms have been replaced by deuterium.

Fast current, large waves, usually associated with holes, boulders, and general turbulence. See Big Water.

A huge flow of water through rapids marked by extreme velocity difference in currents and violent turbulence.
