Which long-term consequence arises from reactor fission product accumulation?

💡 Explanation

Neutron ‘poisoning’ occurs because specific isotopes formed during fission exhibit high neutron absorption cross-sections; therefore, the reactor's ability to sustain nuclear fission decreases steadily, rather than improving moderator efficiency or preventing criticality under all start-up circumstances.
