It is absolutely necessary to control the fission reaction in nuclear power plants.Give scientific reasons.
Answers
A controlled fission reaction is extremely important because everyone knows that an uncontrolled fission reaction is used in nuclear bombs.
A fission reaction is a reaction in which splits the nucleus of an atom into smaller parts releasing a massive amount of energy.
If this reaction is done in a controlled way then the energy released can be used for a number of things like producing electricity and even running a ship.
Answer:
Explanation:
1. In the nuclear power plant, the fission of uranium- 235 atom is done by bombarding neutron on its nucleus.
2. When the fission of one atom of uranium takes place, one atom of barium, one atom of krypton and 3 neutrons are produced.
3. these 3 neutrons again bring about the fission of 3 more atoms of uranium and 9 more neutrons are produced and so on. This is called as chain reaction.
4. During fission of each atom 200 MeV energy is released.
5. If the chain reaction continues uncontrolled, then the energy generation would be tremendous and may result into destructive effects. Therefore, it is absolutely necessary to control the fission reaction in nuclear power plant.
hope its help you.......
