Nuclear Fusion vs. Nuclear Fission

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

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

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)

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

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

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
