Atomic energy:
In view of the fast depletion of our non-renewable resources like coal and petroleum, and because of pollution which power stations burning coal cause, there has been a move to use other means of obtaining energy. Since the energy of the atom had already been unleashed in the form of a bomb, efforts were made to release atomic energy in a controlled manner. The device used for this purpose is called an atomic reactor. Nuclear reactors produce heat, which is commonly used to raise steam, which rotates turbines and generators of electric power. It is estimated that 1 kg of natural uranium, written as U23, generates energy equal to that produced by 35,000 kg of coal. Thus production of energy from nucrear fuel like uranium is efficient, and since great loads of coal or diesel are not consumed daily, this energy is convenient. Nuclear reactors need to be situated at places far away from habitations. They have to be operated under strict safety control, so that there are no accidental leakages of radioactive material. The radioactive wastes have to be carefully disposed off. India is very short of energy and all of you may have heard or experienced power cuts or load-shedding. We have plans to set up several nuclear reactors to generate a good position of our total power requirement.
