Nuclear power has a number of advantages as well as disadvantages. For one thing, nuclear energy is economical and the cost of electricity from a nuclear-power plant is less than that from a coal-fired plant. Be­sides, nuclear power plants do not bum organic fuels and save valuable raw materials such as coal, oil, gas for other uses. They do not pollute the atmosphere with combustion by-products, therefore nuclear plants are ecologically cleaner than the conventional ones.

Although the electricity produced by nuclear power plants is the most promising way of energy-generation, there are some problems as­sociated with nuclear power. First of all, the main problem is to ensure absolute reliability and safety of the plant. It means that all emergency and containment systems must be able to retain fission by-products and to withstand any natural disasters (earthquakes, hurricanes, floods) or even the impact of the crashing plane. The disposal of radioactive waste is still one of the most serious problems. The lack of permanent storage sites can also slow down the development of nuclear industry.

And the last but not the least - uranium resources are not unlimited either. So scientists have to look for other energy sources.
