Abstract
Blocking of a subchannel is one possible scenario for accidents in an operating liquid metal fast breeding reactor. Herein, the understanding the flow behavior neat the locking sites is extremely important. This paper studies the effect of external impact from a sweeping jet on the flow structure in a slot channel behind the fluid lock. We demonstrated that the zone of influence of a sweeping jet on the flow pattern is limited. The spectral analysis method proved that the meandering frequency and frequency of vortex structures propagation in a slot channel corresponds to the Strouhal number equal 0.143. The research results in the case of zero external impact are in compliance with results from other authors.
