  • Nuclear Power
    • Nuclear Fission
      • Produces lots of Energy
      • Can create an uncontrollable chain reaction when the new neutrons move on to divide other nuclei.
      • When a single large Nucleus divides into two smaller Nuclei.
        • Achieved by firing a slow moving Neutron at the Nucleus.
          • Produces three new Neutrons
            • When a single large Nucleus divides into two smaller Nuclei.
              • Achieved by firing a slow moving Neutron at the Nucleus.
                • Produces three new Neutrons
                  • Can create an uncontrollable chain reaction when the new neutrons move on to divide other nuclei.
      • A Nuclear Reactor
        • The Energy released is the result of a controlled chain reaction
          • Boron rods that absorb the nuclei are can be lowered into the containment vessel to slow or stop the chain reaction
        • Uranium-238 rods enriched with Uranium-235 are used as a fuel for the reaction.
        • The daughter nuclei are usually radioactive
    • Nuclear Fusion
      • When two light nuclei; Deuterium and Tritium (isotopes of Hydrogen), join together to produce a heavier and lager nucleus.
        • The larger nucleus is more stable and energy is released.
      • The product is an isotope of Helium.
      • No radioactive waste is produced
      • Produces far more energy than fission
      • Uses readily available materials
      • It is still an experimental process
      • Currently, it requires very high temperatures (Millions of Degrees)
        • Very Expensive
          • It is still an experimental process
          • Needs Very high pressures to make the nuclei fuse together
          • Containment requires very strong magnetic fields for the nuclei (plasma)
      • Needs Very high pressures to make the nuclei fuse together
      • Containment requires very strong magnetic fields for the nuclei (plasma)
