• B. Shut down the reactor.
• C. Both $\left(1\right)$ and $\left(2\right)$
• D. None of these

Answer 1

The correct option is A Slow the neutrons thereby controlling the fission reaction.

Slow the neutrons thereby controlling the fission reaction.

Control rods are used in nuclear reaction to control the fission rate of uranium and plertorium. They are composed of chemical elements such as boron, silver, indium and cadmium that are capable of absorbing many neutrons without themselves fissioning.
