Question
Give a scientific reason.
It is absolutely necessary to control the fission reaction in nuclear power plants.
Advertisements
Solution
- Nuclear fission is a chain reaction.
- In a nuclear power plant, this chain reaction must be carefully controlled.
- If the reaction is not controlled, a large number of neutrons will be produced rapidly.
- These neutrons can cause the fission of more uranium-235 nuclei, leading to an uncontrolled increase in the reaction rate.
- Such uncontrolled chain reactions can release an enormous amount of energy in a very short time and may result in serious accidents.
