  1. Nuclear Energy

  2. Radioactivity’s Beginning • Natural Radioactivity discovered by Antoine Henri Becquerel. • Set up experiment with photographic plates to prove fluorescent materials emitted x-rays • Was cloudy, so he could not develop photograph • When left in drawer with Uranium, photograph developed without sunlight • Phenomenon later named “radioactivity” by Marie Curie in 1898. Deal With It

  3. From Idea to Bomb to Energy • 1939 – Leo Szilard and Enrico Fermi study and measure neutron multiplication, develop idea that some sort of nuclear chain reaction can happen • Idea is originally used for creation of bomb • 1939 –President Roosevelt creates Advisory Committee on Uranium, begins bomb effort. • Fermi achieves the first nuclear chain reaction and sparks Manhattan Project • EBR-1 in Idaho becomes first nuclear reactor to produce electricity • 1957 – Shippingport reactor becomes first commercial reactor

  4. How Does it Work? • When an atom is bombarded with particles, different reactions can take place. They can be absorbed by the atom or bounce off. • Each split makes new nuclei which can be split themselves, creating a nuclear chain reaction. • 1938 - • Otto Hahn hit Uranium with neutrons and observed much lighter elements formed • Explanation: The nucleus had been split into two large fragments (nuclear fission) Otto Hahn says: “Do your homework, kids!’

  5. Or…. • Light nuclei are forced together by forces such as pressure • The fused nuclei will have a lighter mass than the two individual nuclie • According to Einstein, mass is lost in form of energy • E=mc2, or energy equals mass times the constant (speed of light) squared • This is how the sun produces energy • For elements heavier than iron, fission is ideal for producing energy. If lighter than iron, then fusion.

  6. Inside A Power Plant • Neutrons Fired at nuclear material used (generally Uranium -235) • Uranium nuclei split during process of fission • Neutrons from uranium are free to bounce, creating heat • Control Rods Absorb neutrons to contain reaction • Heat produced is transferred to pressurizer. Water is heated to over 600 degrees F, pressure keeps from boiling. • Water flows into steam generators • Steam flows through tube, moves turbine • Steam goes through condenser coolant, condenses into water • Water flows back into water source

  7. Warning: Does Not Actually Explode

  8. Dangers Of Fission For Energy • Chernobyl – 1986 nuclear meltdown in Ukraine • Killed more than 30 people, rendered Chernobyl uninhabitable • Accident attributed to inadequately trained personnel • Led to many changes in design and safety precautions • Biggest and best example of what can go wrong with nuclear power

  9. Advantages of nuclear power • Extraordinary amount of energy from little material • Currently most nuclear material is untapped • No to little pollution (excluding accidents) • Large opportunity for employment

  10. Cons of Nuclear Energy Other Cons to Nuclear Power • Cost – Setting up a nuclear plant can be costly, and so is maintaining it • Potentially contaminates water sources • Unstable nuclear waste must be kept in ideal temperature for centuries after use • Radiation is deadly – potential problems could easily cost lives • Not a renewable resource – just a very efficient one
