What is the role of moderators in nuclear reactors? (2023)

Step 1: Understand that nuclear reactors use a process called fission to generate energy.
Step 2: Know that fission happens when a neutron hits a fuel atom, causing it to split and release energy.
Step 3: Realize that there are two types of neutrons: fast neutrons and slow (thermal) neutrons.
Step 4: Learn that fast neutrons move quickly and are less likely to cause fission in the fuel.
Step 5: Understand that moderators are materials used in reactors to slow down these fast neutrons.
Step 6: Recognize that by slowing down the neutrons, moderators increase the chances of fission occurring.
Step 7: Conclude that moderators are essential for maintaining a controlled and efficient nuclear reaction.
