Nuclear Power Pros and Cons

  1. 1. Nuclear Power: Pros & Cons By: Shokoofeh Akhavan Professor: Emily Brett August 2012
  2. 2. Overview• Origins• Fission• Pros Economic Portability and Productivity Environmental• Cons Waste Storage Accidents National Security
  3. 3. Origins• First Controlled Chain Reaction under University Chicago Football field• First reactor at Oak Ridge National Laboratory 1942• Originally designed production of weapons grade plutonium• First Civilian Reactor in Obinsk, Russia 1952
  4. 4. Nuclear Power CycleFunctions Similarly to any fossil fuel power plant
  5. 5. Pros• Economic• Environmental• Portability & Productivity
  6. 6. Economic• Net external Costs are much cheaper then other forms of production• As of 2005 Nuclear power was : – 3/4 the cost of coal – 1/5 the cost of gas• Nuclear energy is, in many places, competitive with fossil fuels for electricity generation, despite relatively high capital costs and the need to internalize all waste disposal and decommissioning costs.
  7. 7. Environmental• Lowest impact on the environment• No combustion thus Zero emissions of greenhouse gases – Only external product is Steam• Water used for cooling can be interchanged with the environment
  8. 8. Portability and Productivity• Because nuclear power produces an enormous amount of energy using a very small amount of fuel, its average production cost is just 1.87 cents per kilowatt hour.• A good wind project produces electricity only about 30 percent of the time. The sun shines only part of the time in much of the world, but nuclear energy is beneficial for various military and civilian applications.• It leads to relative large amount of energy that produced per land area.
  9. 9. Cons• Waste storage• Accidents• National Security• Ease of peaceful usage to weapons program
  10. 10. Waste Storage• One of the biggest disadvantages of nuclear energy is the waste:• Store in cool dry place• Radioactive indefinitely• Difficult to store• Has deadly Radiation
  11. 11. Disasters• One of the biggest disadvantages of nuclear energy is the occurrence of accidents due to core meltdown.• Chernobyl – Worst nuclear accident• Three Mile island – Worst US Nuclear accident• Most recent Dimitrovgrad in 1996• Most deadly recently Japan in 1994
  12. 12. National Security• Waste storage sites, Plants, various aspects of transporting fissile material are “targets” to hostiles• Not enough is being done to protect these sites
  13. 13. Power vs. Weapons• Peaceful energy production can be very easily turned around into a weapons program• Turn around time depending on reactor is approx 6 months
  14. 14.
