What are the two substances used as moderators in nuclear reactors?
Wiki User

Moderators contain materials that rapidly slow neutrons down to thermal speeds without absorbing a significant number of neutrons. A few of these are:
- carbon, usually in the form of graphite
- heavy water
- light water
- hydrocarbons, like oils
- beryllium (usually too expensive)
- etc.

∙ 15y agoThe majority of reactors use water as the moderator, or the "slower-downer" of the fast neutrons produced in fission reactions.

How are nuclear reactors used in nuclear reactors?
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
Which one among the following is used as a moderator in nuclear reactors?
You don't give the examples, but the moderators used are 1. Heavy water 2. graphite 3. light water.
What type of nuclear reaction is used in modern day nuclear reactors?
Current nuclear reactors rely on nuclear fission as their nuclear reaction.
What does D2O stand for?
D2O stands for Deuterium Oxide. It is also known as Heavy water. It is widely used as moderators in nuclear reactors. Deuterium is a isotope of Hydrogen, with a neutron along with the lone proton, that is why it is called heavy water.
What process release the energy in the nuclear reactors used in power plants?
Nuclear fission
What substances are used as moderators in a nuclear reactor?
carbon and water.
How are nuclear reactors used in nuclear reactors?
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
What kind of elements are used in nuclear reactors?
Uranium is the fuel... moderators can be water... control rods are various substances to absorb extra neutrons some use carbon. Steel (iron) is what the reactor vessel is made of.

What type of nuclear reaction is used in modern day nuclear reactors?
Current nuclear reactors rely on nuclear fission as their nuclear reaction.
What nuclear reaction is currently used to produce nuclear energy in nuclear reactors?
We use nuclear fission in nuclear reactors to tap nuclear energy.
Are lasers used for nuclear reactors?
No, at least not for power reactors
What can be found on the moon that can be used for nuclear reactors?
There may be Radium, Thorium, Uranium or even Plutonium which can be used in nuclear reactors.
What can be used as a substitute for nuclear reactors?
No substitute for nuclear power reactors especially if there is no available fossil fuel.
What fields are plutonium used in?
Nuclear reactors and nuclear weapons
Is nuclear fission only used to create atomic bombs?
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
An element used in nuclear reactors?
Uranium, plutonium, thorium as nuclear fuels. Heavy water and water as cooling agents or moderators. Zirconium and stainless steels for nuclear rods cladding, calandria, pipes, etc. Also graphite, helium, beryllium, cadmium, indium, silver, gadolinium, etc.
