Global performance comparison between the different types of cores.

  Standard oxide fuel cores as SPX, EFR types CADOR oxide fuel Core
Transient over power    
Large gas bubble through the core Prompt reactivity excursion/fuel melting No fuel melting
Full core compacting Prompt reactivity excursion/fuel melting No fuel melting
All control rods withdrawal due to core support structure breaking Prompt reactivity excursion/fuel melting No fuel melting
Unprotected loss of coolants    
Loss of primary pumps Na boiling No Na boiling
Loss of heat sink Equilibrium temperature = 800 °C Equilibrium temperature = 650 °C
Loss of primary and secondary pumps Na boiling Na boiling
