Question # 1

Why are heavy nuclei unstable?

Ans 1: Heavy nuclei are unstable because their binding energy per nucleon is less than lighter nuclei.So less energy is required to break heavy nuclei and they become unstable.

Question # 1

What are thermal reactors?

Ans 1: The thermal reactors are called thermal reactors because the neutrons must be slowed down to thermal energies to produce further fission,They use natural uranium or slightly enriched uranium as fuel.

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.
