MCQ Questions or Viva Questions on Nuclear Power Plant

The nuclear power plant provides approximately 11% of total power generation. The largest producers are the United States and France. Find the MCQ Questions here:

  • Which of the following energy is non-conventional?
  1. Fossil fuels
  2. Biomass energy
  3. Hydroelectric energy
  4. Nuclear energy
  5. Wind energy

Ans: (4) and (5)

Explanation: Nuclear energy is the new source of energy and it is limited. Other sources, such as Fossil fuels, biomass energy, and hydroelectric energy have been used for a long time. Solar energy, ocean energy, wind energy, atomic energy, and geothermal energy are also the source of non-conventional energy.

  • How a nuclear reaction is different from a chemical reaction?
  1. In a chemical reaction neutron involves but in a nuclear reaction, it does not.
  2. In a nuclear reaction, the nucleus involves but in a chemical reaction it does not.
  3. In a chemical reaction, the electron has no role, but in a nuclear reaction, the electron has a great role.
  4.  None of the above

Ans: (2)

Explanation: Chemical reactions and nuclear reactions are completely different. In a chemical reaction, electron transfers/moves/changes its place from one element to another element. Then, one ionic bond forms a combined element. There are no electron transfers in the case of a nuclear reaction. In a nuclear reaction, the nucleus changes. The nucleus of an atom contains protons and neutrons. In this case, as the nucleus changes completely, there is a formation of a new element.

  • The word fission means:
  1.  Split up
  2.  Combining
  3.  None of the above
  4.  Same as fusion

Ans: (1)

Explanation: The word fission means to split up or breaking up into parts. ‘Fusion’ means the process of joining two or more things together to form a new element.
