VERIFICATION OF COMPUTATIONAL MODELS BY COMPARISON OF FINITE-ELEMENT CALCULATIONS AND EXPERIMENTS FOR THE MODEL CASK CASTOR® HAW/TB2

The mechanical analyses in the context of the transport licensing of the type B(U)F package CASTOR® HAW28M Cask for Transport and Storage of Radioactive Material are based upon drop tests with a 1:2 scale model. These tests were accompanied by calculations using Finite Element (FE) analyses. The purpose of the drop tests was to verify the computational models by comparing numerical and experimental results and to comprehensively study the loading situation of the package under accident conditions with respect to stresses, strains, deformations as well as the kinematical behavior. For the drop tests under consideration, a 1m pin drop and a 9m slapdown, we observe excellent agreement between experimental and numerical results.
