Abstract

Abstract

The characteristic of nuclear plant natural circulation flow instability under rolling motion condition was carried out experimentally. The results showed that the flow oscillation caused by rolling motion and the density wave oscillation made the system oscillate with overlapped effect, which made the system more instable. Based on the frequency chart analysis, the effect of overlapped was analyzed.
