Answer
Moderator: The purpose of the use of a moderator is to slow down the speed of neutrons and to allow a fission chain reaction to run smoothly. Heavy water and graphite are generally used as good moderators.
Control rod: Control rods are capable of absorbing neutrons and are used to ensure that neutron flux is under control and hence chain reaction is controlled.
