Fission and fusion
Physics · Secondary 4 · Hard · Fission and fusion
Scientists are trying to produce energy by fusing deuterium and tritium nuclei. Why is sustaining nuclear fusion in a power station much more difficult than sustaining nuclear fission?
- The nuclei repel each other, so very high temperature and pressure are needed
- Fusion needs slow neutrons, which are difficult to produce
- Fusion produces no radiation, so it cannot release much energy
- Fusion only occurs at low temperatures, which power stations cannot reach
