In Nuclear Fusion, we join lighter lighter nucleus to make a heavier nucleus
It produces a tremendous amount of energy, and this same energy is the source of energy in Sun and Stars
The conditions required for fusion are extreme - millions of degrees of temperature and million of pascals of pressure.
In a Nuclear Bomb ,
- Fission of Uranium or Plutonium takes place at the Core
- This core is embedded in a substance containing Deuterium and Lithium
- When the bomb is detonated, fission takes place and the temperature of this substance is raised to 107K in a few microseconds.
- This provides the conditions for fusion of lighter nuclei to take place,
- and due to Nuclear fusion, a devastating amount of energy is released
Nuclear Power Plants
Nuclear power plant is based on the idea of nuclear fission.
In a Nuclear Power Plant, nuclear fuel undergoes self-sustaining fission reaction,
which releases energy at a controlled rate
Advantages of Nuclear Energy
Disadvantages of Nuclear Energy
- Major hazard of Nuclear Power Generation is the disposal of used fuels - used Uranium still decays into subatomic particles (i.e. radiations)
- Improper Nuclear Waste storage and disposal results in environmental contanimation
- There is risk of leakage of Nuclear Radtion
- The Nuclear fuels - such as Uranium has limited availability
- Setting up a Nuclear Energy Power Plant has a high cost
