Abstract

Abstract

The transient CHF calculation code was used to analyze the CHF characteristics under inlet flow oscillation conditions. The calculation results show that: Inlet flow oscillation would have significant effects on critical heat flux. Especially the CHF characteristics would be deteriorated when the oscillation magnitude and period are increased, the heated length is decreased or the outlet quality is decreased. The effect of inlet flow oscillation on CHF would have detrimental impact on the safety of the reactor system.
