The reactions are controlled to regulate energy output.
In power reactors the fission chain reaction is maintained at a controlled (critical) level using control rods, moderators and coolant systems so heat is produced steadily and safely. Uncontrolled reactions are what nuclear weapons do; feeding all products back or immediately removing them would either be impractical or stop the reaction and so wouldn’t produce usable, sustained power.
