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 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
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
Primary function of moderator in nuclear reactor?
What is the primary function of a Moderator in a nuclear reactor
Is helium or carbon or hydrogen or beryllium the best ideal moderator for use in the core of a nuclear reactor?
Carbon is a very good moderator, for use in gascooled reactors, the others not.
What part of the nuclear powerplant does the chain reaction occur?
In the reactor core, which is the volume filled with the fuel assemblies
Why do the control rods need to be inserted into the reactor core?
Control rods are inserted into the reactor core to shutdown the plant, making it super-sub critical, even more so then the negative reactivity coefficient than the thermal effects of the moderator (generally, water).
Why is the moderator important in a nuclear reactor?
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.
What is a bare reactor?
It is a nuclear reactor without reflector, consisting only from fuel and moderator.
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.
Does a graphite moderator cool a reactor?
The primary role of graphite moderator is to moderate the neutron energies however it may also capture some heat during reactor operation.
What are the functions of pressure vessel and turbine in a nuclear reactor?
The pressure vessel contains the reactor core with its fuel, coolant, moderator, control elements, and emergency systems. The turbine is the device that on receiving the steam it spins and turns the electric generators to produce electricity.
