same as ordinary water, but the heavier Deuterium atoms are more effective at slowing neutrons to thermal energies.

How heavy water is used to make plutonium from uranium?
Heavy water is used in nuclear reactors as moderator for neutrons.
What is heavy water used for?
Heavy water is used in making hydrogen bombs.
What are the moderator used in a nuclear reactor with natural uranium?
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
The advantage of heavy water as coolant over light water in pressurized reactors?
In the CANDU reactor heavy water is used as the moderator. It is a much better moderator than light water because it does not absorb neutrons so strongly, and enables non-enriched uranium to be used. The heavy water moderator is enclosed in a tank with fuel channel tubes, called technically a calandria. The coolant is also heavy water which flows through the tubes and hence past the fuel elements, and then transfers its heat to a light water secondary circuit. In a PWR or BWR light water is used both as moderator and coolant, which is obviously much cheaper and less complicated, but does require uranium enriched in U-235.
Heavy water is preferred as a moderator over normal water?
Heavy water has the advantage of being a good moderator and of absorbing fewer neutrons than does light water, so that natural (unenriched) uranium can be used. Light water demands enriched uranium, around 4 to 5 percent U-235. So you can make a choice: use heavy water which is expensive to produce, or use light water and expensive enriched uranium. You can see the different approach between the US and Canada. In the US there was experience of enrichment from the WW2 Manhattan project, in Canada there was no such experience but they had cheap hydro power to use to produce heavy water, so developed the Candu type of reactor.

What is heavy water used for?
Heavy water is used in making hydrogen bombs.
How tritium is formed in a presurized heavy water reactor?
Tritium is formed by the capture of neutrons by deuterium (heavy hydrogen) which is in the heavy water in the moderator and coolant.
What is used as an efficient moderator in a majority of reactors?
Light water (H2O) and heavy water (D2O)
Which material is used as a moderator in nuclear power plant?
It can be light water, heavy water, or graphite
Two important functions of heavy water in a candu reactor?
moderator, coolant
Which is used as moderator in nuclear reactor?
Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
The moderator used in the nuclear reactor at Madras atomic power station in Kalpakkam is?
Heavy water(PHWR)--Pressurised heavy water reactor
What are the moderator used in a nuclear reactor with natural uranium?
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
How can neutrons be slowed in the reactor core?
This is the function of the moderator, which may be heavy water, light water, or graphite
Are the PHWR and PWR are same?
They are the same in that they don't allow reactor coolant water boiling in the primary water coolant loop. They are different in that in PHWR the moderator is heavy water while in PWR the moderator is normal light water.
