The best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.
<h3>What is a nuclear reactor?</h3>
A nuclear reactor, often known as an atomic pile, is a device that initiates and controls nuclear chain reactions or nuclear fusion processes.
Nuclear reactors are used in nuclear power plants to generate energy as well as in nuclear marine propulsion.
Control rods are employed in nuclear reactors because the processes that occur in a nuclear reactor are very exothermic.
As a result, when these control rods are infused into a nuclear reactor, they absorb neutrons and aid in the management of the chain reaction. As a result, the rate of the chain reaction is brought under control.
As a result, we may infer that the statement control rods are employed to slow down the reaction in the reactor core when it gets too hot is correct.
Hence the best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.
