Unresolved problems related to the performance of containment recirculation sumps

Creators

Description

Experiments are being conducted at full geometric scale to investigate the performance of containment sumps during the recirculation mode of the ECCS. Such sumps are prone to vortex formation and perform poorly if break-flow jets impinge nearby. If they do not function well, air and poor flow conditions can exist in the pump approach piping. Since these systems must function for long periods of time unattended, it is necessary to understand the effect of flow configurations, geometric configurations, and vortex suppression techniques
