Which outcome occurs when a reactor uses uranium isotopes enriched beyond criticality limits?

💡 Explanation

A supercritical mass initiates exponential fission because neutron production vastly exceeds absorption or leakage; therefore, a chain reaction escalates, leading to a power surge. A criticality excursion results, rather than a drop in coolant pressure due to other problems.
