  • Nuclear power

    1. 1. Nuclear Power: Pros & Cons Group Members: Darrel Anderson Nicholas Azadian Richard Klimas Jr.
    2. 2. Origins Nuclear Power <ul><li>First Controlled Chain Reaction under University Chicago Football field </li></ul><ul><li>First reactor at Oak Ridge National Laboratory 1942 </li></ul><ul><li>Originally designed production of weapons grade plutonium </li></ul><ul><li>First Civilian Reactor in Obinsk, Russia 1952 </li></ul>
    3. 3. Fission <ul><li>Typical element used is Uranium 235 </li></ul><ul><li>Uranium 235 unstable </li></ul><ul><li>Forms Uranium 236 with neutron </li></ul><ul><li>Breaks down to Krypton 92, Barium 141 </li></ul><ul><li>High energy release and neutrons </li></ul><ul><li>http://static.howstuffworks.com/flash/nuclear-uranium.swf </li></ul>
    4. 4. Nuclear Power Cycle (Simplified) <ul><li>Functions Similarly to any fossil fuel power plant </li></ul><ul><li>http://static.howstuffworks.com/flash/nuclear-power-reactor.swf </li></ul>
    5. 5. Pros <ul><li>Economic </li></ul><ul><li>Environmental </li></ul><ul><li>Portability & Productivity </li></ul>
    6. 6. Economic <ul><li>Net external Costs are much cheaper then other forms of production </li></ul><ul><li>As of 2005 Nuclear power was : </li></ul><ul><ul><li>3/4 the cost of coal </li></ul></ul><ul><ul><li>1/5 the cost of gas </li></ul></ul>
    7. 8. Cost Comparison
    8. 9. Efficiency <ul><li>Average thermal efficiency 35% </li></ul><ul><ul><li>Comparable to Coal, Natural Gas </li></ul></ul><ul><li>1 Uranium Pellet can produce: </li></ul><ul><li>Equivalent to: </li></ul><ul><li>1780 lbs of coal </li></ul><ul><li>17,000 cubic feet of natural gas </li></ul><ul><li>149 gallons of oil </li></ul>
    9. 10. Portability and Productivity <ul><li>Wide range of uses </li></ul><ul><li>Various military and civilian applications </li></ul><ul><li>Relative large amount of energy produced per land area </li></ul>
    10. 11. Environmental <ul><li>Lowest impact on the environment </li></ul><ul><li>No combustion thus Zero emissions of greenhouse gases </li></ul><ul><ul><li>Only external product is Steam </li></ul></ul><ul><li>Water used for cooling can be interchanged with the environment </li></ul>
    11. 12. Cons <ul><li>Waste storage </li></ul><ul><li>Accidents </li></ul><ul><li>National Security </li></ul><ul><li>Ease of peaceful usage to weapons program </li></ul>
    12. 13. Waste Storage <ul><li>U 235 and Pu 239 half lives are: </li></ul>
    13. 14. Waste Storage <ul><li>Store in cool dry place </li></ul><ul><li>Radioactive indefinitely </li></ul><ul><li>Difficult to store </li></ul><ul><li>Has deadly </li></ul><ul><li>Radiation </li></ul>
    14. 15. Safety <ul><li>Always potential for meltdown </li></ul><ul><ul><li>Human error, Mechanical Failure </li></ul></ul><ul><li>Materials are still fissile after thousands of years </li></ul><ul><li>In the past there have been many accidents but few that caused environmental contamination </li></ul>
    15. 16. Radiation and You
    16. 17. Meltdown <ul><li>The various mechanical/ structural failures include: </li></ul><ul><li>Pumps breakage </li></ul><ul><li>Turbine/Tank rupture </li></ul><ul><li>http://www.ida.liu.se/~her/npp/demo.html </li></ul>
    17. 18. Disasters <ul><li>Chernobyl </li></ul><ul><ul><li>Worst nuclear accident </li></ul></ul><ul><li>Three Mile island </li></ul><ul><ul><li>Worst US Nuclear accident </li></ul></ul><ul><li>Most recent Dimitrovgrod in 1996 </li></ul><ul><li>Most deadly recently Japan in 1994 </li></ul>
    18. 19. National Security <ul><li>Waste storage sites, Plants, various aspects of transporting fissile material are “targets” to hostiles </li></ul><ul><li>Not enough is being done to protect these sites </li></ul>
    19. 20. Summary <ul><li>History Synopsis </li></ul><ul><li>Economic Potential </li></ul><ul><li>Safety </li></ul><ul><li>Questions? </li></ul>
