Which consequence arises when reactor-grade enriched uranium contains excessive U-236?

💡 Explanation

Neutron absorption by U-236 increases parasitic absorption of neutrons, because neutron absorption by U-236 represents neutron poison feedback. Reduced neutron multiplication follows; therefore operation becomes unstable rather than more efficient configurations since more core material is needed.
