Graphite is used because it slows down the speed of neutrons so that the nuclear reaction can occur in a controlled manner.

Moderator means to slow down the neutrons. With the help of graphite electrode.

In nuclear reactor cadmium rod and D2O is used to moderate the electron to speed down the reaction.

@S Kumur.
Why cadmium rods are used?

Graphite moderating ratio is 170. It is a second best moderator first is D2O.

In nuclear reactors. There is. No participation of electrons. Only proton and neutron only. In this case, both graphite and heavy water (20. Atomic mass) are suggestible.
Both reduce the speed of neutrons.
Then, The probability of colliding nature of neutrons to uranium will increase.
In each collision, 3 neutrons released out of 3, two are absorbed by cadmium rods. Remaining 1 neutron speed will be controlled by graphite and heavy water.
