Which consequence results when prompt criticality occurs in nuclear fuel?

💡 Explanation

An uncontrolled chain-reaction power excursion occurs because the prompt criticality mechanism initiates instant and rapid nuclear fission; therefore, dangerous overheating happens rather than controlled power increase via delayed neutrons.
