A
Reduce temperature
B

C
Control the reaction
D
Cause collision with the fast moving neutrons to reduce their speed
Correct Answer: Cause collision with the fast moving neutrons to reduce their speed
Neutron moderator. Neutron moderators are a type of material in a nuclear reactor that work to slow down the fast neutrons (produced by splitting atoms in fissile compounds like uranium-235), to make them more effective in the fission chain reaction.
