Differences between nuclear fission and nuclear fusion reaction
May 5, 2018
S.N | Nuclear fission | Nuclear fusion |
1. | The reaction in which a single heavy nucleus splits into two or more light nuclei is called nuclear fission reaction. | The reaction in which two or more light nuclei combine to form a single heavy nucleus is called nuclear fusion reaction. |
2. | It can be controlled. | It cannot be controlled |
3. | An atom bomb is made on the basis of this reaction. | A nuclear bomb is made on the basis of this reaction. |
4. | It occurs in the form of chain reaction. | It does not occur in the form of chain reaction. |
5. | Less energy is produced comparatively. | More energy is produced comparatively. |
6. | The heavy nucleus is bombarded with neutrons. | Light nuclei are heated to an extremely high temperature. |
7. | Raw material is not easily available and is costly. | Raw material is comparatively cheap and easily available. |
8. | Disposal of nuclear waste is great environmental problem. | Disposal of nuclear waste is not involved |
9. | It does not occur normally in nature. | It occurs in stars, such as sun. |
10. | Critical mass of the substance and high speed neutrons are required. | High density, high temperature environment is required. |
11. | It produces many highly radioactive particles. | Few radioactive particles are produced by this reaction. |
12. | It takes little energy to split two atoms in this reaction. | Extremely high energy is required to bring two or more protons close enough. |
13. | Proper mechanisms are available to have control over it. | Proper mechanisms are yet to be developed regarding this reaction. |
