Reactor kinetics is the study of the rates of nuclear reactions within a nuclear reactor. It focuses on how the concentration of nuclear fuel and other materials changes over time, influencing the reactor's behavior and safety. Understanding these rates is crucial for controlling the reactor's power output and ensuring it operates efficiently. The key components of reactor kinetics include neutron flux, which is the flow of neutrons in the reactor, and reactor feedback mechanisms, which help maintain stability. By analyzing these factors, engineers can predict how the reactor will respond to changes, such as adjustments in fuel or coolant flow.
