Question

What is the purpose of Boron rods in a nuclear reactor ?

• A. Absorb excess neutrons
• B. Absorb alpha particles
• C. Slow down the speed of neutrons
• D. Speed up the reaction

Answer 1

The correct option is A Absorb excess neutrons

Boron rods are used as control rods in nuclear reactors to control the fission rate of uranium and plutonium. These are capable of absorbing many neutrons without fissioning themselves. Composition of control rods is designed for the neutron spectrum of the reactor.
