Which outcome arises after repeated nuclear fuel cycles?

💡 Explanation

Neutron absorption increases because of the accumulation of neutron-absorbing fission products during fuel burnup. Therefore, the surplus parasitic capture reduces efficiency rather than optimizing conductivity because fission products are not efficient fuel materials, and criticality is harder because the chain reaction gets more difficult to sustain.
