Which mechanism limits energy release during nuclear fission within reactor fuel rods?

💡 Explanation

Fission product accumulation increases core binding energy, thereby reducing the energy released per fission event, because the resulting nuclei become more stable; therefore, higher energy is needed to overcome the binding, rather than accelerating the chain reaction.
