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, natural) uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a … 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, … 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 than … 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 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 … 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 … See more In terms of safeguards against nuclear weapons proliferation, CANDUs meet a similar level of international certification as other reactors. … See more 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), … See more WebCANDU reactor gives two options for burning Thorium. In the first option, only one fuel type is used in the reactor core which is a mixture of slightly enriched Uranium and natural thorium. The other design, there are 3 layers. The innermost layer has 6.0% wt. of gadolinium to shape the flux distribution. The middle layer has same fuel as the ...
