THREE-DIMENSIONAL FINITE ELEMENT IMPACT ANALYSIS OF A NUCLEAR WASTE TRUCK CASK
A three-dimensional finite element impact analysis of a hypothetical accident event for the preliminary design of a shipping cask to be used to transport radioactive waste by standard tractor-semitrailer truck is presented. The dynamic structural analysis code DYNA3D, run on Sandia's Cray-1 computer, was used to calculate the effects of the closure-end of the cask impacting a rigid, frictionless surface on an edge of its external impact limiter after a 30-foot fall. The center of gravity of the 304 stainless steel and depleted uranium cask was assumed to be directly above the impact point. An elastic-plastic material constitutive model was used to calculate the nonlinear response of the cask components to the transient loading. Results from the calculations show the cask sustained large localized deformations. However, these were almost entirely confined to the impact limiters built into the cask. The closure sections were determined to remain intact and leakage would not be expected after the event. Interactive color computer graphics were used throughout the analysis, proving to be extremely helpful for generation and verification of the geometry and boundary conditions of the finite element model and for interpretaton of the analysis results.
