Presentation transcript:

Nuclear Fusion

Fusion Reaction Deuterium Tritium n n n + + FUSION! Very Unstable!!

Fusion Reaction ENERGY!! Very Unstable!! + + Therefore, bonds need to reform to stable atoms and release energy n n + n + ENERGY!! neutron Helium atom (alpha)

Fusion Occurs at very high temperatures 40,000,000 K That’s why that darn sun is so hot!! Cold fusion could still be possible energy source in the future

Nuclear Fission

Fission Video Neutron accelerates into an atom (Uranium) Produces more reactions (chain reaction) Continues until no more Uranium

Fission Reactions

Nuclear Reactors Steam moving generator for energy Nuclear Reactor

Control Fission Control Rods - Absorb unwanted neutrons to help control chain reaction Why have there been nuclear accidents? Control rods are located at bottom (instead of top) of reactor. Why important?

Why Nuclear so Bad? Radioactive waste is being stored in sea beds and land (Nevada/Utah) Half-life of most waste are over 100,000 years Uranium is NOT renewable
