which statement describes the function of control rods?\no they release neutrons during fission reactions.\no they undergo nuclear fission reactions.\no they control the rate of reactions.\no they directly convert water to steam.
Answer
Brief Explanations:
Control rods in nuclear reactors are made of materials like cadmium, boron, etc. that absorb neutrons. By absorbing neutrons, they can slow down or speed - up the nuclear chain reaction, thus controlling the rate of reactions. They do not release neutrons, undergo fission themselves, or convert water to steam directly.
Answer:
They control the rate of reactions.
