The nuclear reactor is enclosed in a concrete chamber that has a thick wall so that it can absorb the nuclear radiations.Ī Nuclear power plant or Atomic power plant The nuclear rods can be raised inside or pulled outside the reactor as the demand is. In between the uranium-235 rods are placed boron rods as they help in absorbing excess neutrons and prevent nuclear fission reaction from out of control. Graphite is called the moderator as it helps in slowing down the speed of neutrons so that a proper fission reaction takes place. In a nuclear reactor, uranium-235 rods are inserted in a graphite core. In a nuclear power plant, a fission reaction is carried out in a steel pressure vessel, and inside is a nuclear reactor. Nuclear power plants use nuclear fission reactions to generate electricity and the fuel used for this purpose is uranium-235. Nuclear fission reactions are done to generate electricity at nuclear power plants. However, nuclear fission reaction can be controlled by using boron rods as boron can absorb neutrons. If all the neutrons produced during the fission of uranium-235 produce further fission, then so much energy will be produced that it will not be controlled and leads to an explosion called an atom bomb. ![]() ![]() The neutrons produced in the nuclear fission reaction leads to further fission of heavy nuclei and cause a chain reaction. Also, in a nuclear fission reaction neutrons are used up and produced as well.
