Nuclear power plants produce electricity with principles similar to conventional power plants, heat is used to heat energy to produce steam. Then steam to spin turbines and steam. electricity generator To generate electricity, but the difference is there. Origins of the thermal power, nuclear power plant caused by chemical decomposition of uranium-235. In nuclear fuel The heat from the power plant, the heat from the burning of conventional fuels such as coal or lignite. Natural gas or oil When comparing the amount of fuel used for electricity that you use natural uranium. (U-235 concentration of about 0.7 percent) of one ton can be produced more than 40 million kilowatt / hour. While the need for coal or oil to 16,000 tons to 80,000 barrels (about 13 million liters) to produce electricity as well.
