  • It provides very concentrations of energy as it can provide large amount of energy from small amount of fuel.
  • The reaction gives less annual mortality rate of any energy resource with 90 deaths per trillion kilowatt hours

<u>Disadvantages of Nuclear Fission </u>

  • It is dangerous and  also explosive.
  • It creates harmful and radioactive waste products.
