However, deuterium (the second label in the doubly labeled water) is lost only when body water is lost. Thus, the loss of deuterium in body water over time can be used to mathematically compensate for the loss of 18 O by the water-loss route. This leaves only the remaining net loss of 18 O in carbon dioxide. This measurement of the amount of ...
For instance, the heavy water used in CANDU reactors is a highly enriched water mixture that is mostly deuterium oxide D 2 O, but also some hydrogen-deuterium oxide and a smaller amount of ordinary water H 2 O. It is 99.75% enriched by hydrogen atom-fraction; that is, 99.75% of the hydrogen atoms are of the heavy type; however, heavy water in ...
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D 2 O) as its coolant and neutron moderator. [1] PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium.

Deuterium (hydrogen-2, symbol 2 H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common 1 H has no neutrons. The name deuterium comes from Greek deuteros, meaning "second".
Dennis Whyte, who headed MIT’s Plasma Science and Fusion Center and is now at a commercial spinoff, Commonwealth Fusion Systems, said the NIF ignition had a gain (the ratio of power released to ...
The CANDU (CANada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power. [1] The acronym refers to its deuterium oxide ( heavy water ) moderator and its use of (originally, natural ) uranium fuel.
