Reactor criticality refers to the state in which a nuclear reactor sustains a steady chain reaction, producing a constant output of energy. Achieving and maintaining this balance is crucial for the safe and efficient operation of nuclear power plants, as it ensures that the reactor neither shuts down nor exceeds its designed power limits.

Reactor Criticality

A nuclear reactor is a device used to initiate and control a sustained nuclear chain reaction, primarily for generating electricity or for research purposes. It operates on the principle of nuclear fission, where the nucleus of an atom splits into smaller parts, releasing a significant amount of energy in the form of heat, which is then used to produce steam that drives turbines for electricity generation.

Reactor shutdown is a critical procedure in nuclear reactor operations, involving the cessation of the nuclear fission process to ensure safety and maintenance. It is essential for preventing overheating and potential accidents, and is achieved through the insertion of control rods and other safety mechanisms to absorb neutrons and halt the chain reaction.
