Which risk dominates when uranium fuel rods generate excessive heat?

💡 Explanation

Cladding failure risk dramatically increases when fuel rods overheat due to excessive fission, specifically by thermal creep, because the material softens substantially at intense temperatures; therefore this outcome is the primary threat, rather than reactivity changes.
