Solution

The correct option is D

Nuclear reactor


Answer (D)

Explanation for correct option:

(D)

  • Nuclear reactor- In a nuclear reactor, the fission of uranium is carried out by slow neutrons. While Uranium-235 is the naturally occurring fissionable isotope, there are other isotopes that can be induced to fission by neutron bombardment.
  • Nuclear fission reaction is a reaction in which the nuclei of heavy mass is split into two or more nuclei of smaller mass.
  • In the nuclear fission of Uranium is that some massive isotopes as Uranium-235 are unstable and when split via fission there will be a slow neutron.
  • This slow neutron is again processed to hit another unstable isotope and this vicious cycle continual processing form a chain reaction.

Hence option (D) is the correct option.
