Nuclear fission
and fusion
- Nuclear fission - the splitting up of big atomic nuclei
- Nuclear fusion - the joining
of small atomic nuclei.
- 2 light nuclei (e.g hydrogen) can join to create a
larger nucleus - this is called nuclear fusion.
- Nuclear fusion releases a lot of energy (all the energy
released in stars comes from nuclear fusion).
- Fusion doesn't leave behind a lot of radioactive waste
like nuclear fission, instead it uses hydrogen as its fuel.
- The big problem is that nuclear fusion can only hppen
at very high temperatures (about 10 000 000oC).
- 2 light nuclei (e.g hydrogen) can join to create a
larger nucleus - this is called nuclear fusion.
