Computational Analysis and Evaluation of the Aftereffects of Fuel Assembly Drops Using Verified Deformation Models of Structural Materials

  • Published:
Atomic Energy Aims and scope

The key results of fuel-assembly drop analysis in the event of the breakage of clamping or sling elements and an assessment of the aftereffects in transport-technological operations are presented. The computational analysis was performed using the LS-DYNA dynamic calculation module of the ANSYS software package. Full-scale 3D mathematical modeling allowed a detailed analysis of dynamic processes, cutting the design time, and lowering the cost of the structure being developed. The results obtained made it possible to analyze the impingement process, determine the plastic deformations arising in the elements of fuel assemblies, and make recommendations for strengthening the structure.
