Give scientific reasons:
It is absolutely necessary to control the fission reaction in nuclear power plants.

उत्तर
- One kind of chain reaction is the nuclear fission reaction.
- Nuclear power plants closely regulate these reactions.
- Neutron production may increase uncontrollably if these reactions are not adequately regulated.
- In nuclear power plants, the fission reaction must be strictly controlled because each released neutron triggers the fission of three uranium (U-235) atoms. Uncontrolled reactions can result in dangerous accidents.
