IAS Previous Year Science & Tech Questions | Lecture 5| Nuclear Energy & Sub Atomic Particles_Part-1

Q.1) The difference between a nuclear reactor and an atomic bomb is that 

(a) no chain reaction takes place in nuclear reactor while in the atomic bomb there is a chain reaction

(b) the chain reaction in nuclear reactor is controlled

(c) the chain reaction in nuclear reactor is not controlled

(d) no-chain reaction takes place in atomic bomb while it takes place in nuclear reactor

Q.2) Consider the following statements: In a nuclear reactor, self-sustained chain reaction is possible, because: 

  1. more neutrons are released in each of the fission reactions.
  2. the neutrons immediately take part in the fission process.
  3. the fast neutrons are slowed down by graphite.
  4. every neutron released in the fission reaction initiates further fission.

Which of these statements are correct?

(a) 1, 2 and 3

(b) 1 and 3

(c) 2 and 4

(d) 2, 3 and 4

Q.3) The function of heavy water in a nuclear reactor is to:

(a) slow down the speed of neutrons

(b) increase the speed of neutrons

(c) cool down the reactor

(d) stop the nuclear reaction

Q.4) To meet its rapidly growing energy demand, some opine that India should pursue research and development on thorium as the future fuel of nuclear energy. In this context, what advantage does thorium hold over uranium? 

  1. Thorium is far more abundant in nature than uranium.
  2. On the basis of per unit mass of mined mineral, thorium can generate more energy compared to natural uranium.
  3. Thorium produces less harmful waste compared to uranium.
