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