century, as the growth in electricity demand, people began to propose the idea of
establishing electricity production centers. With the expansion of power application, the
production of electricity needed to form long power generation. Now there are many kinds of power plants: the coal or oil power ones, the hydroelectric ones, the solar power plants, the wind and tidal power ones which are for small power plants and the nuclear ones.
Nuclear power plants satisfy the need of energy in many countries and they play an increasingly important role in the world.
