Which phenomenon limits the usable energy released during nuclear fission reactors?

💡 Explanation

Fission product poisoning limits energy release, because certain isotopes absorb neutrons strongly, halting the nuclear chain reaction; therefore reactor power must be reduced, rather than energy production rising past design thresholds from continuous fission.
