3. Science behind Nuclear Energy  Basis is nuclear fission When a neutron(s) is bombarded to a radioactive substance (i.e Uranium) the substance splits into smaller pieces and emits energy ○ Chain reaction occurs ○ The amount of energy emitted is calculated through E =mc 2 ○ The key is to control the chain reaction

4. Diagram of nuclear fission

5. Efficiency  The fuel (radioactive materials) is inexpensive  Scientifically well developed  Easy to transport power  No greenhouse or acid rain effects  5 cents per kilowatt-hour (way cheaper compared to fossil fuel)

6. Environmental friendly power

7. Korea’s Example  First plant built in 1978 (Gori Plant)  In total there are 20 nuclear power plants  Supplies 45% of total electric consumption  Reason of usage: scarce natural resources

8. South Korea’s electricity production source

9. France’s Example  75% of electricity produced is from nuclear power plants Electricity cost is the lowest among Europe  Largest net exporter of electricity Gains over 3 billion € per year  Manages 59 plants  Has plans for new generation of Nuclear power plants

10. Nuclear power plants in France

11. France’s electricity production source

12. Pros and Cons for nuclear energy ProsCons  Does not produce gaseous emissions  Technology readily available compared to other alternatives (i.e solar energy)  Generates high amount of electricity from single plant  Chances of radioactive contamination  Safety issues (Chernobyl, Three Mile Island)  Nuclear waste causes long range problems  Preferred targets for terrorists
