1. Nuclear Fusion

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

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

4. 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

5. Nuclear Fission

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

7. Fission Reactions

8. Nuclear Reactors
Steam moving generator for energy
Nuclear Reactor

9. 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?

10. 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
