← ScienceWhich risk increases when emergency cooling fails within fission reactor?
A)Fuel assembly structural deformation occurs✓
B)Control rod ejection probability increases
C)Moderator neutron absorption significantly increases
D)Steam turbine blade fatigue accumulates rapidly
💡 Explanation
Fuel deformation increases severely due to excessive temperatures. Decay heat will cause fuel melting; this disruption is due to loss of cooling; therefore fuel structure fails rather than turbine or moderator issues because the cooling system solely addresses fuel rod integrity.
