Question # 1

Describe the principle of operation of solid state detector?

  • Ans 1: A solid state detector is a specially designed p-n junction operating under a reversed bias in which electron-hole pairs are produced by the incident radiation to cause a current pulse to flow through the external circuit.

Question # 1

Discuss the advantages of fission power from point of view of safety,pollution and resources.

  • Ans 1: Advantage of nuclear power are given below
    1. Nuclear fission energy,release a highly reduced amount of the gases into the air,resulting in a slower rate of global warming and pollution.
    2. The energy is quick to create;meaning that they are able to make a large amount of some form of emergency required it.
    3. Much more energy is produced.

Question # 1

What is the function of control rods in nuclear reactor?

  • Ans 1: Controls rods made of Cadmium or Boron are used for the control of number of neutrons,so that of all the neutrons produced in fission ,only one neutrons produces further fission reaction.
    In case of emergency or for repair purpose control rods are used to stop the chain reaction and shut down the reactor.
