Effects and Consequences of Interactions Between Containment Components and Content of Type B Packages During 9 ill Drop Tests

Abstract

Tests with different Type B casks confirm the existence of effects with stress peaks in cask components due to interactions between the cask and its contents. These effects can be caused by a delayed strike of the content onto surrounding cask components which cannot be excluded if the content is movable. Some results of the drop tests with two different Type B casks and with a model designed for the study of this problem are presented in the paper. Results of calculations performed with the ABAQUS computer code and by use of analytical methods to simulate the measured effects are discussed.
