Which outcome results when neutron moderation fails in a reactor?

💡 Explanation

If neutron moderation fails, slow neutrons won't be available to sustain fission. The chain reaction occurs with fast neutrons but causes increased U-238 absorption and higher heat due to uncontrolled fission events; thus, the cladding will melt rather than the chain reaction stopping.
