Graphite is used as moderator since it moderate the speed of neutron. But BARC, uses water as moderator.

Graphite is able to withstand at high temperatures without losing its properties so graphite is used.

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

Graphite is commonly as moderator as they slow down the speed of neutrons produced during fission.

Since graphite absorb neutron. Which helps to produce nuclear reaction in a controlled manner.

Since the graphite reduce the speed of an electron (13,200 km/s) to the speed of (22,000 m/s).

I think graphite used but may be any substance used to slower down the rate of reaction.

Heavy water and graphite are used in nuclear reactor for moderator in nuclear fission.

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