The moderator is used to slow down the neutrons present in the core of the reactor. Normally the neutrons produced as the nuclear fuel (e.g. uranium) is fissioned are travelling too fast to produce a sustained chain reaction. Some examples of moderators are cadmium, heavy water and graphite.
A neutron moderator or graphite moderator turns fast neutrons into thermal neutrons that help sustain a fission reaction.
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
Yes, it is the main moderator function in what is called "thermal nuclear reactors"
Yes, but it would usually be too expensive as tritium must be made in a reactor from lithium.

Moderator is not used in case of fast breeder reactor because there is no need to slow down neutron energy. Nuclear fission takes place at high energy of neutrons.
What is the primary function of a Moderator in a nuclear reactor
moderator
Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
It is a nuclear reactor without reflector, consisting only from fuel and 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.
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
Yes, they are fast nuclear reactors
By the control rods and by the moderator.

Thermal Breeder Reactors use moderators but Fast Breeder Reactors don't use moderator.
