Which risk increases in a nuclear reactor after uncontrolled chain fission?

💡 Explanation

Fuel weakening results from overheating by fission. Because energy dissipation lags runaway fission, high temperatures weaken materials via creep, therefore reducing the cladding strength occurs rather than changes to Xe-135 concentration or moderator behavior within safe operating conditions.
