Check what you remember
Read the wording for your board, then hide it and explain Neutron moderation and chain reactions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Fission neutrons are released fast and must be slowed to sustain further fission, since moderating them increases the probability of further induced fission.
