Which consequence results when fuel enrichment errors in a nuclear submarine core allows prompt criticality?

💡 Explanation

An errors causing prompt criticality leads to an uncontrolled power excursion, due to the increased fission rate with only prompt neutrons. The mechanism initiating this phenomenon is neutron multiplication. because power rises rapidly, it causes fuel overheating/damage, therefore answer A, rather than being controlled, as would occur with delayed neutrons or moderator control.
