Question
Explain how in nuclear energy is generated through nuclear fission process.
✓

Answer

  • In a process in which nucleus of a heavy atom (such as uranium, plutonium or thorium) can be split into lighter nuclei when bombarded with low-energy neutrons is called nucler fission.
  • A tremendous amount of energy is released.
  • During this, if the mass of the original nucleus is just a little more than the sum of the masses of the individual products.
  • The fission of an atom of uranium produces $10$ million times energy produced by the combustion of an atom of carbon from coal.
  • Nuclear fuel releases energy at a controlled rate through self sustaining fission chain reaction in a nuclear reactor designed for electric power generation.
  • The released energy can be used to produce steam and further generate electricity
