Which material is used in controlling chain reaction in nuclear reactor?

The material used to slow down high-speed neutrons in a reactor is called the moderator. The moderator in a pressurized water reactor is the water, which is the main coolant. Collisions between the neutron and hydrogen nuclei (protons) slow the neutron down (thermalizing it) and increasing the probability that it will be absorbed by another fissionable atom. That makes the chain go, it maintains the chain reaction. Slowing down neutrons does NOTslow down the process of nuclear fission. If anything, it maintains it or speeds it up because slower moving neutrons have a higher probability of being absorbed and continuing or building the chain reaction. A link is provided.

What is artificial nuclear reactor?
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
What is the purpose of a reaction chamber in a nuclear reactor?
neutron absorber
In a nuclear power plant fission reactions are controlled by inserting what?
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
Which material is used as a controller in a nuclear reactor?
Boron Carbide.
If you wanted to slow down the chain reaction in a nuclear reactor would you remove or insert the control rods?
In order to slow down the chain reaction in a nuclear reactor, i.e. to reduce KEff, you would insert the control rods.
How is the controlled release of nuclear energy in a reactor accomplished?
controlling a chain reaction
What does reactor mean?
The term reactor refers to a structure in which material can be made to undergo a controlled nuclear reaction. They are used widely in industrial plants.
What is artificial nuclear reactor?
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
What is pwr and bwr?
I think you are talking about nuclear reactors. PWR is a Pressurized Water Reactor, and is the basis for most power generators. BWR is a Boiling Water Reactor. As the water is a major moderating component, controlling the speed and intensity of the nuclear reaction, the steam bubbles in a BWR can present a problem.
What is the meaning of nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What is meant by nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What type of reaction take place in a nuclear reactor?
Nuclear fission, not to be confused with fusion.
What is the purpose of a reaction chamber in a nuclear reactor?
neutron absorber
What is the function of an electrical reactor?
A nuclear reactor contains a nuclear reaction, provides support for the control mechanisms for the reaction, and provides for the transfer of heat to machinery that will use it to produce electric power.
In a nuclear power plant fission reactions are controlled by inserting what?
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
Do nuclear reactors have critical mass?
We know that critical mass can be achieved in a nuclear reactor. If it could not, we'd not be able to get a chain reaction and generate heat to generate power. Reactors don't have critical mass when the control rods are in, but pull the rods, start the reactor up and away you go!
How do you use radioactive material?
If you are a smart guy, you can make a nuclear bomb, or a nuclear reactor...
