Nuclear power plants

  1. 1. Nuclear Power Plants<br />May 11, 2010<br />
  2. 2. Objectives<br />Define core, heat exchanger, turbines, and cooling system<br />Describe the process of making electricity<br />Determine limiting factors of nuclear energy<br />
  3. 3. Nuclear Core<br />Where the nuclear reactions (fission) take place, produces huge amounts of heat (energy), changes water to steam<br />
  4. 4. Heat Exchanger<br />The steam from the core heats the water in the heat exchanger into steam (like a boiler)<br />
  5. 5. Turbines<br />Steam from the heat exchanger is blown through the turbine making it spin creating electricity<br />
  6. 6. Cooling System<br />Steam is released into something that can cool it down, usually water or the air<br />
  7. 7. Diagram of a Nuclear Power Plant<br />
  8. 8.
  9. 9. Limiting Factor of Nuclear Power<br />Uranium and plutonium do not decay into stable atoms for a long period of time<br />Decay: particles that continue to give off different forms of energy<br />Can happen over a long or short period of time<br />
  10. 10. Nuclear Waste<br />Half-life: time that it takes for nuclear waste to become stable<br />Uranium: 713,000,000 years<br />Plutonium: 24,000 years<br />This is why the government wants to store nuclear waste underground at a place like Yucca Mountain<br />
  11. 11. How much radiation are you exposed to?<br />Add the numbers that apply to you…<br />Radiation from space 26<br />Elevation (636 ft.) 2<br />Radiation from the ground 46<br />If you live in a house made of stone, brick, or concrete add 7<br />Radiation from your body 240<br />Weapons testing 1<br />For every 1,000 miles traveled by air, add 1<br />
  12. 12. How much radiation are you exposed to?<br />If you have porcelain crowns for false teeth, add 0.07<br />If you use gas lanterns when camping, add 0.003<br />If you wear an LCD watch, add 0.006<br />If you use luggage inspection at airports, add 0.002<br />If you watch TV, add 1<br />If you use a video display terminal, add 1<br />If you have a smoke detector, add 0.008<br />If you have a pacemaker, add 100<br />If you have had x-rays, add 40<br />Add together all the numbers that apply to you<br />
