摘要

乏燃料贮存格架是用于贮存换料后的乏燃料组件的重要设备

其自由放置在核电厂乏燃料水池中

在地震载荷下的响应属于非线性响应

包含了各种复杂的运动:滑移、碰撞、扭转、倾覆等。为了准确描述上述非线性响应

本文建立了乏燃料贮存格架整池有限元模型并进行非线性时程分析

考虑了滑移、碰撞、摩擦等影响因素

同时还考虑了乏燃料贮存格架在水池中的流固耦合效应。通过时程分析得到了乏燃料贮存格架在地震载荷下的位移、载荷等计算结果。该方法可用于乏燃料贮存格架的抗震分析。

Abstract

Background: Spent fuel racks are important facilities to store the spent fuel which are freestanding in the spent fuel pool.The response of racks to seismic load is highly nonlinear and involves a complex combination of motions: sliding

impact

twisting and turning.Purpose: An analysis method should be built to accurately replicate these nonlinear responses.Methods: The whole pool multi-rack FEA model was developed and time history analysis was performed which contains the consideration of effect of sliding

impact and friction and the fluid structure interaction effect.Results: The analysis results such as displacement and force under seismic loads were obtained.Conclusions: The method can be used to the seismic analysis for spent fuel racks.
