WebA high-performing reactor with capacity factors regularly in the range of 88%, our mid-size (740 MW) CANDU reactors are ideally suited for countries looking to replace an existing … WebJan 4, 2024 · The CANDU reactor core consists of a calandria, an unpressurized vessel of heavy water with hundreds of tubes running through it to contain the nuclear fuel. Whereas LWRs must be shut down every 12–18 months to be refueled, CANDUs were designed to allow on-line refueling. The reactors remain operating as fresh fuel bundles are inserted …
WebIts four CANDU reactors are owned and operated by OPG. Despite its smaller size, the Pickering station powers up to 2.5 million households. Point Lepreau was the first CANDU 6 reactor to be licensed for … 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 …
WebUnenriched natural uranium is appropriate fuel for a heavy-water reactor, like a CANDU reactor. On rare occasions, earlier in geologic history when uranium-235 was more abundant, uranium ore was found to have naturally engaged in fission, forming natural nuclear fission reactors. WebA CANDU reactor contains either 380 or 480 fuel channels and calandria tubes, depending on its power output, and two such critical work packages involve removing and replacing pressure tubes and calandria tubes – with each one taking approximately one month to replace – which has clear implications for outage time. ...
WebNeutron moderator. In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy. These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium ...
