Which risk increases when neutron moderation fails during fission?

💡 Explanation

Prompt criticality accelerates when reactivity increases unboundedly because neutron moderation failure disables absorbing neutrons, triggering uncontrolled exponential fission known as prompt criticality; therefore, a rapid increase is likely, rather than managed control through rods.
