Which risk increases in a nuclear reactor core during supercriticality?

💡 Explanation

Fuel cladding failure risk increases significantly because uncontrolled nuclear fission generates extensive heat; this thermal runaway stresses the cladding, initiating creep and cracking. Therefore cladding failure will occur rather than the other events, which involve distinct nuclear mechanisms influencing reactor control.
