Which risk increases when reactor fuel rods exceed temperature limits?

💡 Explanation

An uncontrolled chain reaction can start due to Doppler broadening, with increased neutron capture likelihood because higher temperatures induce more energetic neutrons, therefore raising fission rate; rather than direct efficiency loss, blade failures and coolant problems depend on slower responses.
