  1. Nuclear Reactors Heather Haycock Tech 1030

  2. Fission vs. Fusion • Fusion

  3. Fission vs. Fusion • Fission

  4. Using Nuclear Power • Provides 11% of World’s electricity • Little to no greenhouse gas pollution • 1 pellet is equivalent to 149 gallons of oil or 1 ton of coal • Nuclear power plants can run nonstop for months

  5. Boiling Water Reactor

  6. Pressurized Water Reactor

  7. Fuel Assembly • Fuel Rods placed in Fuel assemblies with control rods • Uranium 235 Pellets placed end to end to make Fuel Rods

  8. Reactor Vessel • Fuel Assemblies Placed inside reactor vessel • Control Rods Removed, Fission Takes Place • Fission Reaction Heats up water, which travels through pipes in a closed system

  9. Reactor Vessel • Hydraulic like system • Uses spargers, a type of spray nozzle to push water into the reactor • Uses a hydraulic reactor coolant pump to cool down the water

  10. Turbine and Generator • A second closed system of water is heated by first • Turns to steam and rotates a turbine • Attached to rotating shaft to turn electromagnet generator • Magnet creates electricity

  11. Lake or Cooling Towers • Steam passes through a third closed water system, called condenser coolant • Some plants discharge water into a lake next to the plant • Others Use Cooling towers so water can be recycled.

  12. Efficiency Pros Cons Creates radioactive waste Uses 672 gallons of water per 1 megawatt-hour of energy produced Second most expensive method for producing electricity • A lot of energy stored in a very small amount of space • Little greenhouse gases • Water can be reused countless times

  13. Fission Reactors • Would produce much more energy than fission reactors • Limitless fuel available • Zero greenhouse gases • Core radioactive for only 100 years
