Where are the nuclear reactors in Canada and what are they called?
Mostly in Ontario, one in Quebec and one in New Brunswick. They are all CANDU type, ie heavy water moderated and cooled.
Is fools gold heavy?
Fools gold (iron pyrite) is relatively heavy, it is about one fourth to one third as heavy as gold and about as heavy as iron.
Is silver a dense or heavy metal?
not heavy not medium density
How heavy is osmium?
Osmium is one of the heaviest elements known; it is twice as heavy as lead and 22 times as heavy as water
Are Dunka Doos heavy?
The Dunka Doo toys are heavy after you finished dunking them.
Name one type of nuclear reactor?
CANDU, a reactor type designed in Canada which uses heavy water as the primary coolant.
What type of nuclear reactor is used in Ontario to produce electricity?
This is the Candu type, which was uniquely developed in Canada to use heavy water moderator and natural uranium fuel
What type of nuclear reactor does Canada sell to other countries?
The Candu reactor, which is a heavy water moderated reactor with horizontal pressure tubes enclosing the fuel rods. Something unique to the Canadians, but which has been successful and is installed also in several power stations in Canada, mostly in Ontario.
State different names of thermal power plant?
Different types of nuclear plants: Pressurised Water Reactor (PWR); Boiling Water Reactor (BWR); Heavy Water Moderated Reactor (CANDU); Advanced Gascooled Reactor (AGR); Fast Breeder Reactor (FBR); Pebble Bed Gascooled Reactor; Water Cooled Graphite Reactor (RBMK). There are other ideas that only exist on paper.
What is a nuclear reaction coolant?
Presumably you mean nuclear reactor coolant? This is the fluid that transfers the reactor thermal output to the steam raising units in a PWR, or to the turbine in a BWR, in which cases it is natural water. Gas cooled reactors can use carbon dioxide or helium, and CANDU reactors use heavy water.

In nuclear reactor heavy water is used as?
Heavy water (deuterium) functions as a moderator. It slows down fast neutrons released by fission reactions in order to allow the reaction to be sustained. Fast neutrons pass through the reactor before initiating another fission reaction.
What are nuclear reactors called?
One type (model) of reactor is the CANDU, or Canada (CAN) dueterium-uranium (DU)reactor. Ther are also differences between fusion and fission reactors, fast and thermal reactors (the differences bing in the speed of the neutrons used to initiate the chain reaction, usually fission), light or heavy water cooled or moderated reactors, and many other distinctions.
Why Pressurized Water Reactor nuclear reactor is the most commonly used reactor?
I guess because it is the one with the fewest operational problems and the longest operational life. BWR's introduce the problems of a contaminated turbine. Gas cooled graphite reactors are efficient but there are life limitations on the graphite. Heavy water reactors have the benefit of using natural uranium but the heavy water is very expensive to produce. So the choice is between enriching uranium as for the PWR, or producing heavy water as for the CANDU. Most countries are now opting the PWR way as enriching uranium by centrifuge has become much less expensive than the old gaseous diffusion method.
The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
Heavy water(PHWR)--Pressurised heavy water reactor
How many type of nuclear energy?
Nuclear fission reactors come in various forms, though the principle of using the heat from a nuclear chain reaction is always the same. 1. Pressurised Water Reactor (PWR). 2. Boiling Water Reactor (BWR). 3. Magnox gas cooled reactor (no longer built) 4. Advanced gas cooled reactor (no longer built but still in use in UK). 5. Canadian heavy water reactor (Candu) 6. Russian design of Chernobyl type. I think this covers the most used types for power generation. There are others such as the gas cooled pebble bed reactor, and the fast breeder reactor, that are possible but designs have not been so successful and these have not been adopted commercially.
What do you use heavy water for?
Moderator in some types (e.g. Candu) of nuclear reactor to slow high energy fission neutrons to thermal energies.In small quantities it can be used for MRI contrast.It can be used to slow chemical reactions in water solution.etc.
