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".
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.
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 ...
