==Key Stage 4==
===Meaning===
A '''nuclear chain reaction''' is when the [[neutron]]s released from one [[Nuclear Fission|nuclear fission]] event triggers one or more other [[Nuclear Fission|nuclear fission]] event.

===About Nuclear Chain Reactions===
: For a '''nuclear chain reaction''' to occur each [[Nuclear Fission|nuclear fission]] event must cause the release of at least 1 [[neutron]].
: In a [[Nuclear Reactor|nuclear reactor]] on [[Mean Average|average]] 1 [[Nuclear Fission|fission]] [[neutron]] from each [[Nuclear Fission|fission]] event goes on to cause one more [[Nuclear Fission|fission]] event. This results in a constant release of [[energy]].
: A '''nuclear chain reaction''' can only happen if enough [[Thermal Neutron|thermal neutron]]s are produced from the [[Nuclear Fission|fission]] events.

 : For a '''nuclear chain reaction''' to occur each [[Nuclear Fission|nuclear fission]] event must cause the release of at least 1 [[neutron]] which can go on to cause a second [[Nuclear Fission|fission]] event.
 : In a [[Nuclear Reactor|nuclear reactor]] on [[Mean Average|average]] 1 [[neutron]] from each [[Nuclear Fission|fission]] event goes on to cause one more [[Nuclear Fission|fission]] event. This results in a constant release of [[energy]].
-: The [[neutron]]s used to induce [[Nuclear Fission|fission]] must have a low [[energy]] to be captured by a [[Atomic Nucleus|nucleus]] otherwise the [[neutron]]s will just pass straight through without being captured. [[Neutron]]s with the right amount of [[energy]] to be captured are called [[Thermal Neutron|thermal neutron]]s because they have a similar [[energy]] to [[molecule]]s in the [[air]] at [[Room Temperature|room temperature]].
+: During [[Nuclear Fission|nuclear fission]] the [[neutron]]s produced usually have too much [[energy]] to be captured by the [[Atomic Nucleus|nucleus]] of another [[atom]], so they must be slowed down by a [[moderator]] to a lower [[energy]] in order for  a '''chain reaction''' to occur.
 : A '''nuclear chain reaction''' can only happen if enough [[Thermal Neutron|thermal neutron]]s are produced from the [[Nuclear Fission|fission]] events.
