• Uranium that is naturally found is not capable of initiating a proper nuclear reaction. Enrichment helps in making naturally mined uranium capable of initiating a chain reaction.

Why enrichment is needed?

  • Uranium oxide which is the outcome of uranium mining and processing contains two types (or isotopes) of uranium: U-235 and U-238.
  • The concentration of U-235 is less than 2% and nearly 99% is U-238.
  • Natural wetland is known for its floating gardens (“rad”),which is  used for cultivating vegetables and flowers.
  • Higher concentration of U-235 is needed for initiating a chain reaction. The enrichment process is done with the help of centrifuge.

What is a Centrifuge?

  • Centrifuge is a device which helps in increasing the concentration of U-235 in naturally mined uranium oxide.
  • Uranium in its gaseous form of uranium hexafluoride. is used in centrifuge.
  • The difference in weight is primarily utilised in centrifuge.
