==Key Stage 4==
===Meaning===
A '''Nuclear fission reactor''' is a device used to [[Energy Transfer|transfer]] [[energy]] from the [[Nuclear Potential Energy Store|nuclear potential energy store]] to the [[Thermal Energy Store|thermal energy store]] of an [[object]] with a [[Nuclear Fission|nuclear fission]] [[Nuclear Reaction|reaction]].

===About Nuclear Fission Reactors===
: 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]].
: 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.
: [[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]].

[[Moderator]] - The [[Fuel Rod|fuel rods]] are surrounded by a [[moderator]] which slows down the [[neutron]]s released in [[Nuclear Fission|nuclear fission]] events so they can be be captured by a second [[Atomic Nucleus|nucleus]] to cause a second [[Nuclear Fission|nuclear fission]] event.

[[Control Rod]]s - Large rods of [[Boron]] can be moved in and out of the '''reactor''' to slow down or stop the [[Nuclear Fission|nuclear fission]] [[Nuclear Reaction|reaction]] by absorbing the [[neutron]]s and preventing them from moving from one [[Fuel Rod|fuel rod]] to the other.

: The [[Fuel Rod|fuel rods]] in a '''nuclear reactor''' are slim to allow [[neutron]]s to escape the [[Fuel Rod|fuel rods]] easily. This prevents a single [[Fuel Rod|fuel rod]] from sustaining a [[Nuclear Chain Reaction|chain reaction]]. The [[Fuel Rod|fuel rods]] are placed next to each other so that the [[neutron]]s released by one [[Fuel Rod|fuel rod]] are absorbed by another [[Fuel Rod|fuel rod]]. This also allows them to have [[Control Rod|control rods]] placed between them to stop the [[Nuclear Reaction|reaction]].
