==Key Stage 4==
===Meaning===
A '''thermal neutron''' is a [[neutron]] which is moving slow enough that it can be captured by a [[Atomic Nucleus|nucleus]].
===About Thermal Neutrons===
: '''Thermal neutrons''' are named as such because they have the same [[Kinetic Energy Store|kinetic energy]] as [[molecule]]s in the [[air]] at [[Room Temperature|room temperature]].
: [[Neutron]]s released during [[Nuclear Fission|nuclear fission]] are too fast moving to be captured by [[Atomic Nucleus|nuclei]] so they must be slowed by a [[moderator]] to become [[Thermal Neutron|thermal neutrons]].
