What is a neutron moderator, a term coined by Wheeler?
A neutron absorber
A type of neutron star
A particle accelerator
A reactor component
Answer
A neutron moderator is a reactor component that slows down fast neutrons produced by nuclear fission to make them more likely to be absorbed by fissile material, such as uranium-235 or plutonium-239, and sustain a chain reaction. This process is crucial for controlling the rate of nuclear reactions within a nuclear reactor and maintaining a steady power output or achieving criticality in nuclear weapons
