Which of the following materials is used to control the rate of neutron production in a nuclear reactor?
Answer Details
Boron rods are used to control the rate of neutron production in a nuclear reactor. Boron is a good neutron absorber and it is able to absorb neutrons without itself undergoing fission, so it is used to control the rate of fission in the reactor. By inserting or removing the boron rods from the reactor core, the amount of neutrons available to sustain the fission chain reaction can be controlled, and the reactor's power output can be adjusted accordingly.
