Answer
To absorb neutrons and control the chain reaction
Explanation
Control rods are designed to absorb neutrons, which helps regulate the rate of the chain reaction in a nuclear reactor.
Common mistake
Misunderstanding Control Rod Function
Students often think that control rods completely stop the fission process instead of absorbing some neutrons to regulate the chain reaction.
Clarify that control rods are used to absorb excess neutrons, which helps maintain a controlled chain reaction rather than halting it entirely.
