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.
