  • 1. TOPIC:- ENERGY RESOUCESSub Topic:- NUCLEAR POWER PLANTS
  • 2. A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. As in a conventional thermal power station the heat is used to generate steam which drives a steam turbine connected to a generator which produces electricity. As of February 2, 2012, there were 439 nuclear power plants in operation.
  • 3.  Nuclear reactors work in a similar way to other power plants, but instead of using coal or gas to generate heat, they use nuclear fission reactions. In most cases, heat from the nuclear reactions convert water into steam, which drives turbines that produce electricity.
  • 4.  Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.
  • 5.  Nuclear Plant is an efficient source of power. The energy released from the fission of an atom of uranium is 10 million times the energy produced from the combustion of a carbon atom in coal. As fission uses less ore than that used by coal plants, the environmental costs associated with its mining and transport, such as fuel for transportation and pollution from the transport trucks, are also reduced. There is no everyday pollution from nuclear power plants, and the nuclear generation of energy does not lead to global warming. In addition, this method of energy production does not deplete the supply of fossil fuel.
  • 6.  An accident in a nuclear fission plant can release radioactive elements that are toxic to life, both at the time of the accident and for many years after. The 1986 explosion at Chernobyl killed 31 people, and another 15,000 may die within the next 50 years due to the radioactive fallout. The waste from nuclear plants is radioactive and needs to be carefully transported and stored in a long-term facility, away from life. After 10 years, the waste products are 1,000 times less radioactive, and after 500 years, they are less radioactive than the original uranium ore. Each nuclear power plant in the United States generates about 10 cubic feet of waste annually, which is sent to Europe for reprocessing.
