Question

Quizplus · Accepted Answer

Control rods in a nuclear reactor are made of substances such as boron, cadmium, or hafnium, which are capable of absorbing neutrons. By inserting or removing these rods into or out of the reactor core, the rate of nuclear reactions can be controlled, and the amount of heat generated can be adjusted. Therefore, control rods are primarily used to absorb neutrons and regulate the reactor's power output, making option E the best choice.
