Heavy Water

Heavy Water is literally DeuteriumDeuteriumDeuterium is a type of two stable isotopes of hydrogen, the other being Protium. Deuterium has 2H - as it's name is greek deuteros, meaning "second". It is often used in Nuclear Reactors, primarily in Heavy Water (which is deuterium oxide); however it can be naturally found in Light Water or ocean water aswell. oxide. It's molecular formula is that of regular Light WaterLight WaterLight water, although appearing to have a fancy name, is literally just ordinary water....except it does contain a small amount of Heavy Water. The point of light water is that it can be used as a moderator --however it can only be used in certain situations, as it absorbs too many neutrons to be used with unenriched uranium (which is why light water is presumably used in Spent Fuel Pools) Light water is mainly used in BWR reactors & PWR reactors Uranium Enrichment is necessary for the usage of--H2O, however it contains two atoms of deuterium and one atom of Hydrogen; resulting in 2D2O.

It is about 10.6% denser than tap water and has a higher melting point, tasting slightly sweeter and can affect bioloigcal systems; large amounts are needed to poison humans, although it is toxic.

It is produced using the Girdler sulfide process, and the usages of Heavy Water is mainly for nuclear science; such as it's usage in PHWRPWR reactorThis reactor is a PWR reactor - a pressurized water reactor. This is a specific type of Nuclear Reactor--in that it is pressurized water. This is also the most common type of reactor used and produced. The fuel rods are pressurized with helium, and the fission gas products result in more stability; as fuel "burns" in the reactor, the density increases resulting in small voids developing. Helium pressurization is necessary as these voids can cause potential rupture of fuel rods. Furthermore, the reactors or other heavy water reactor desgins.
