Which outcome results from neutron moderation failure in uranium fission?

💡 Explanation

Neutron moderation slows neutrons to sustain fission; without it, neutrons are too fast. Chain reaction efficiency collapses and thermal runaway accelerates because the rapid increase in fast neutron flux causes uncontrolled, very high-energy fissions, therefore leading to exponential overheating, rather than a controlled process.
