Tritium is generated in the fuel of all reactors; CANDU reactors generate tritium also in their coolant and moderator, due to neutron capture in heavy hydrogen. Some of this tritium escapes into containment and is generally recovered; a small percentage (about 1%) escapes containment and is considered a routine radioactive emission (also higher ...
Four years later, Unit 2, another CANDU 6-reactor, achieved criticality on 6 May 2007 [10] and was connected to the national grid on 7 August. It began operating at full capacity on 12 September 2007, [ 11 ] also producing 705,6 MW.
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
The power plant comprises eight CANDU pressurized heavy-water reactors arranged into two plants (A and B) with four reactors each. Each reactor stands within a reinforced concrete containment. The steam generators are 12 m tall, and weigh 100 tonnes each.
The Pickering station is a large multi-unit nuclear facility, comprising six operating CANDU nuclear reactors with a total output of 3,114 MW when all units are on line, and two non-operating units with a total output of 1,030 MW currently shut down in safe storage. [8]
Between 1983 and 1986, the Pickering B group went online and also in 1983 the single CANDU reactor at Point Lepreau began operation, as did the Gentilly 2 CANDU reactor. Between 1984 and 1987 the Bruce B group began commercial operation, and also in 1987 the CANDU design was ranked one of Canada's top-10 engineering achievements.
In this file image shows the outside of the Unit 3 reactor containment building at Plant Vogtle in Waynesboro. Unit 3 reached “initial criticality” earlier this week, a key step in generating ...
The Darlington reactors have been among the best performing in OPG's CANDU fleet, including a top year in 2008 in which the plant achieved a combined 94.5% capacity factor. [28] In June 2016, the World Association of Nuclear Operators (WANO) named Darlington one of the safest and top-performing nuclear stations in the world - for the third time ...
