Definition of fissions per second
Check what you remember
Read the wording for your board, then hide it and explain fissions per second in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The power output depends on the number of fissions per second, so controlling how many neutrons go on to cause further fissions is exactly how the output of a reactor is controlled.
