How many CANDU reactors are there in the world?
30 CANDU reactors
CANDU reactors in the world There are 30 CANDU reactors in operation globally. As well, India developed the design and built 16 reactors that are based on the CANDU design.
What is a CANDU reactor and why was this controversial?
Federal officials hailed the sale as a major step in building Canada’s presence in China. But at home, the sale provoked an explosion of protests. To critics, it presented the deplorable spectacle of Canada selling sensitive technology to a country known for its human-rights violations and poor environmental record.
How do CANDU reactors operate?
CANDU reactors produce electricity through a process known as fission. Fission is the process of splitting atoms of natural uranium inside the reactor, releasing radiation and heat. The heat – energy – is harnessed to make steam to power the turbines and generators, which in turn produce electricity.

What happened to the Candu reactor?
Of the 29 commercial CANDU reactors built, 22 are in Ontario. Of these 22, a number of reactors have been removed from service. Two new CANDU reactors have been proposed for Darlington with Canadian government help with financing, but these plans ended in 2009 due to high costs.
What are CANDU nuclear reactors?
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.
How safe are Canada’s nuclear reactors?
Canada’s nuclear reactors are safe for workers, the public and the environment. Safety is not only built into the design of CANDU reactors but the whole nuclear fuel cycle and Canada’s robust regulations for nuclear power.
What are the advantages of the CANDU nuclear reactor?
I liked the Candu design and can see a number of advantages over comparable light water reactors. It can be operated with natural uranium, which contains 0.72\% of the fissile isotope, U-235, whereas a light water reactor, because of the neutron absorption characteristics of water, requires enrichment, frequently to 2.4–2.8\% U-235.
What is the difference between PWR and CANDU nuclear weapons?
CANDU are economically less effective then PWR. It is expensive to maintain them, it is expensive to build them. CANDU are allowing the recipient country to produce weapon-grade Plutonium/U-233 (main components of nuclear weapons ) much easier then standard PWR, as Indians had eagerly showed to the world.
Why did Canada choose the CANDU uranium enrichment system?
Other than the required capacity & cost to enrich uranium, the other major reason for why Canadians went with the CANDU design was to do with “in-house” manufacturing capabilities at the time, which were not able to build large high pressure vessels required for PWR.
