The speed of fast-moving neutrons in a nuclear reactor can be reduced by using?
graphite rods
concrete shield
iron rods
boron rods
Correct answer is A
Moderation is the process of the reduction of the initial high speed (high kinetic energy) of the free neutron.
Since energy is conserved, this reduction of the neutron speed takes place by transfer of energy to a material called a moderator.
There are several different types of moderating materials, and each have places where they are used more effectively.
Typically-used moderator materials include heavy water, light water, and graphite.
