Flashcards in Nuclear Fusion Deck (5):
What is nuclear fusion?
The joining of small atomic nuclei to create a larger nucleus
Fusion release a lot of energy (more/less than fission for given mass) - all the energy released in [ ] comes from fusion. So people are trying to develop [ ] to generate electricity.
What are the advantages of fusion?
Doesn't leave behind radioactive waste like fission and there's plenty of hydrogen available to use as fuel.
What is a problem with fusion?
The big problem is that fusion can only only happen at really high temperatures - about 10,000,000°C
You can't hold the hydrogen at the high temperatures and pressures required for fusion in an ordinary container - you need an extremely strong magnetic field.
