1. Nuclear Fusion vs. Nuclear Fission

2. Fission
Process = nucleus __________________ into 2 or more fragments and releases energy
One split causes ________________________________________
Used by nuclear power plants

4. Fission Disadvantages
Fission Advantages
No ______________________________________________________________________ (i.e. greenhouse gases)
Lots more energy than coal or oil
We ________________________________ fission
Fission Disadvantages
Produces lots of ___________________________________
Expensive and dangerous to operate (3 Mile Island, Chernobyl, Fukushima)
Requires ___________________________________ _____________________________as fuel

5. Recent Technological Advances for Fission
Experimenting with ______________________________ instead of uranium
____________________________________ and more abundant
____________________________________________________
Superior nuclear properties
Not as easily turned into a ______________________________
Present infrastructure doesn’t support it (this is a problem)

6. Fusion
Process = ___________________ atoms (i.e. hydrogen) ___________________ to form ___________________ atoms (i.e. helium, carbon, etc.)
Energy process of the sun and stars

7. Fusion Advantages Fusion Disadvantages
Produces __________________________________________________________________________
Creates huge amounts of energy
Huge amounts of _______________________ fuel available (Hydrogen-2 available from sea water)
Fusion Disadvantages
_____________________________________
Potentially dangerous to perform (needs tons of safety monitoring)
Could require more energy than it produces

8. Recent Technological Advances for Fusion
Have been trying to make fusion possible since the 1950s, many countries working together
Jet: 1990s in UK, show that it is possible to fuse hydrogen and then release energy but takes more energy as input than output
ITER: World’s largest nuclear fusion reactor currently being build in France, predicted to begin fusing by 2030.
Trying to make self-sustaining that would create “star-like” environment to cause controlled nuclear fusion
Will use and remote handling
