5 nuclear energy

  1. 1. Nuclear Energy
  2. 2. <ul><li>Nuclear Energy- when energy is released when the nucleus of an atom breaks apart (nuclear fission). This nuclear energy is converted to electrical energy. </li></ul><ul><li>Nuclear Reactor- uses the energy from controlled nuclear reactions to generate electricity. </li></ul>
  3. 3. <ul><li>Advantages of Nuclear Power </li></ul><ul><li>- Emits low amounts of carbon dioxide. There is little effect on global warming. </li></ul><ul><li>Generates large amount of electrical energy from 1 plant. </li></ul>
  4. 5. Bright green- countries building their first reactors Green- countries building new reactors Tan- countries planning/considering their first reactors Olive green-  countries planning/considering new reactors Blue- countries with reactors, but no plans for expansion or phase-out Light blue- countries with reactors considering phase-out Brown- countries which formerly had commercial reactors, but all have been phased out Gray- countries without commercial reactors Red- countries that have declared themselves free of nuclear power and weapons
  5. 8. <ul><li>Risk of Nuclear Power </li></ul><ul><li>-Uranium (Environmental damage) </li></ul><ul><li>-Water from reactor must be cooled before it’s released into streams. (harm fish, animals & plants) </li></ul><ul><li>- Nuclear waste- radioactive by-product that results when radioactive materials are used. </li></ul>
  6. 9. <ul><li>Radiation from Nuclear Power Plants </li></ul><ul><li>Ex: 1986 Chernobyl, Ukraine </li></ul><ul><li>Reactor core overheated and caught fire and caused a chemical explosion that blew a hole in the reactor. </li></ul><ul><li>-28 people died from acute radiation sickness </li></ul><ul><li>-260,000 people exposed to high levels of radiation. </li></ul>
  7. 10. Chernobyl, Ukraine- 9 miles away from plant
