Question

Which statement best describes control rods?

They are unmovable pieces.
They are inert.
They supply neutrons to start the nuclear chain reaction.
They drive the generator

Answer 1

B. They are invert. I just took that question.

Answer 2

The correct answer is "They are inert. "

Control rods are placed in a nuclear reactor. Control rods absorb many neutrons but they themselves do not undergo nuclear fission reaction. Control rods are made up of elements like boron, cadmium, silver and Indium.

As they are inert control rods help to regulate the rate of fusion reaction of plutonium and uranium in a nuclear reactor.
