What are the fuctions of moderator and controller in nuclear reactor?

- moderator, slows fast fission neutrons to thermal (near room temperature) energies rapidly enough to prevent their capture by uranium-238 before they can participate in the chain reaction and fission uranium-235
- control, remove excess neutrons so as to hold the reactor at exactly critical at all times, permit control of increases and decreases of operating power level

Primary function of moderator in nuclear reactor?
What is the primary function of a Moderator in a nuclear reactor
Slows down neutrons in a nuclear reactor?
moderator
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.
How is the rate of the fission in a nuclear reactor controlled?
By the control rods and by the moderator.
Does a breeder nuclear reactor use moderator?
Thermal Breeder Reactors use moderators but Fast Breeder Reactors don't use moderator.

What is a bare reactor?
It is a nuclear reactor without reflector, consisting only from fuel and moderator.
Why does the core of the reactor have a moderator?
The core of the reactor contains the nuclear fuel. Having a moderator in place within the core ensures that the nuclear fuel is processed at an accurate time duration. This can prevent serious problems from occurring within the entire nuclear 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).
Can a reactor without moderator is present?
Yes, they are fast nuclear reactors
How is the rate of the fission in a nuclear reactor controlled?
By the control rods and by the moderator.
Do moderator in nuclear reactor slows down the neutrons emitted during fission?
Yes, it is the main moderator function in what is called "thermal nuclear reactors"
Which material is used as a controller in a nuclear reactor?
Boron Carbide.
Does a breeder nuclear reactor use moderator?
Thermal Breeder Reactors use moderators but Fast Breeder Reactors don't use moderator.
What is in the core of a nuclear reactor?
The core of the nuclear reactor includes:nuclear fuel elements (composed of the fuel meat covered with cladding)reactor coolantreactor moderator (for thermal reactors)control elementsmeasuring instrumentsstructural and support structures
