Key Stage 4
Meaning
A nuclear chain reaction is when the neutrons released from one nuclear fission event triggers one or more other nuclear fission event.
About Nuclear Chain Reactions
- For a nuclear chain reaction to occur each nuclear fission event must cause the release of at least 1 neutron.
- In a nuclear reactor on average 1 fission neutron from each fission event goes on to cause one more fission event. This results in a constant release of energy.
- A nuclear chain reaction can only happen if enough thermal neutrons are produced from the fission events.
