Abstract

In the past decade, multiple accidents related to spent fuel pools have occurred consecutively, a large part of which are related to the large sloshing of the liquid inside the spent fuel pool under earthquake action. In order to study the influence of liquid sloshing on the dynamic characteristics of spent fuel pools in nuclear power plants, the modal, liquid sloshing height, and response spectrum of spent fuel pools with different liquid to liquid ratios were analyzed under seismic action using the Coupled Eulerian-Lagrangian analysis method. The analysis results showed that as the liquid content increases, the stiffness of the liquid structure coupling system tends to decrease. When the planar shape of the pool was fixed, under the same seismic excitation, regardless of the liquid content in the pool, the maximum height of liquid sloshing was basically the same. When the liquid content in the spent fuel pool is 4/5, the seismic performance and functional utilization of the pool are good. The liquid exerts a damping effect on the wall of the spent fuel pool. As the liquid to water ratio increases, thinner pool walls are more affected by water sloshing effects compared to thicker pool walls.
