Nuclear Chain Reaction

A nuclear chain reaction is a process in which the nucleus of an atom undergoes a nuclear reaction that releases a large amount of energy, and in turn, causes neighboring nuclei to undergo similar reactions. This process can result in the release of an enormous amount of energy, as is the case in nuclear power plants and nuclear weapons.

Key Concepts

1. Nuclear Fission: The process in which the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy.
2. Neutrons: Subatomic particles that are crucial for initiating and sustaining a chain reaction.
3. Critical Mass: The minimum amount of fissile material required to sustain a chain reaction.
4. Control Rods: Devices used to regulate the rate of the chain reaction in nuclear reactors.
5. Chain Reaction Rate: The speed at which the nuclear reactions propagate through the material.
