Reactor Components as Mechanism

The idea
A controlled reactor relies on a moderator to slow neutrons for fission, control rods to regulate reaction rate, and a coolant to carry heat away.
In practice
Inserting control rods further into the core absorbs more neutrons, slowing fission and reducing power output.
Where people slip
Each component performs one distinct role — treating them as interchangeable, or one alone as controlling, misreads the system's balance.
