WebCANDU reactors. CANada Deuterium Uranium (CANDU) reactors use heavy water as a coolant and moderator instead of regular old light water. These were invented and developed in Canada in the 1960’s, when Canada decided that they did not want to build enrichment plants or large pressure vessel manufacturing capabilities. The CANDU development effort has gone through four major stages over time. The first systems were experimental and prototype machines of limited power. These were replaced by a second generation of machines of 500 to 600 MWe (the CANDU 6), a series of larger machines of 900 MWe, and finally developing into … See more The CANDU (Canada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power. The acronym refers to its deuterium oxide (heavy water) moderator and its use of (originally, See more The CANDU includes a number of active and passive safety features in its design. Some of these are a side effect of the physical layout of the system. CANDU designs … See more The neutron economy of heavy-water moderation and precise control of on-line refueling allow CANDU to use a wide range of fuels other … See more Tritium, H, is a radioactive isotope of hydrogen, with a half-life of 12.3 years. It is produced in small amounts in nature (about 4 kg per year globally) by cosmic ray interactions … See more The basic operation of the CANDU design is similar to other nuclear reactors. Fission reactions in the reactor core heat pressurized water in a primary cooling loop. A heat exchanger, also known as a steam generator, transfers the heat to a secondary cooling … See more A heavy-water design can sustain a chain reaction with a lower concentration of fissile atoms than light-water reactors, allowing it to use some alternative fuels; for example, "recovered uranium" (RU) from used LWR fuel. CANDU was designed for … See more In terms of safeguards against nuclear weapons proliferation, CANDUs meet a similar level of international certification as other reactors. The plutonium for India's first nuclear … See more

WebCANDU is the most efficient of all reactors in using uranium: it uses about 15% less uranium than a pressurized water reactor for each megawatt of electricity produced. Use of natural uranium widens the source of supply and makes fuel fabrication easier. Most countries can manufacture the relatively inexpensive fuel. WebCANDU reactors were first developed in the late 1950s an 1960s bi a partnership atween Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of … small world children\\u0027s dentistry
