Which consequence occurs during uncontrolled nuclear reactor fission?

💡 Explanation

Uncontrolled fission leads to excessive heat generation; therefore, surpassing the coolant's critical heat flux causes rapid vaporization via nucleate boiling collapse, rather than increased neutron moderation which normally stabilizes the chain reaction because fuel elements will melt.
