Description
Background: Spent fuel racks are important facilities to store the spent fuel which are free standing 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. Conclusion: The method can be used to the seismic analysis for spent fuel racks. (authors)
