Seismic sloshing of reactor tank with internals

A large commercial size breeder reactor tank contains a huge amount of liquid sodium. Due to the presence of large free-surface areas, the liquid sodium will participate in sloshing motion under seismic disturbances. Of interest in the reactor design is the magnitude of the hydrodynamic pressure acting on the internal components and the maximum wave height of the free-surface when coolant sloshes. This paper presents a new seismic analysis methodology which calculates the sloshing loads on submerged components. Results of a study performed on the sloshing of a reactor tank with many in-tank components are also discussed. Objective is to investigate the effects of the internal components on the sloshing response and to calculate the maximum sloshing loads on internal components that can be used for design purposes.
