→About Nuclear Chain Reactions
===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]] which can go on to cause a second [[Nuclear Fission|fission]] event.
: 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.
