Complete the text Nuclear power plantsAbout 10% of the world's electric power is produced by пустоnuclear power plants. Nuclear power requires little пустоfuel and causes much less air pollution than other power plants, but it can cause severe health and пустоenvironmental problems when accidents occur, with a consequent release of radioactive material. This type of energy is produced by the splitting of atoms of uranium, which releases пустоheat . This process - called fission - produces large amounts of steam, which is used to turn the blades of пустоturbines thus creating energy. The main problems with пустоnuclear power are linked to the location of the power plants, as people are not willing to have these plants near their homes, and the disposal of пустоwaste material, which stays radioactive for centuries.
