9 m Side Drop Test of Scale Model

A type B(U) shipping cask had been developed in KAERI for trrutsporting PWR spent fuel. Since the cask is to transport spent PWR fuel, it must be designed to meet all of the structural requirements specified in domestic packaging regulations and IAEA safety series No.6. This paper describes the side drop testing of a one - third scale model cask. In order to evaluate the structural integrity of this cask under the 9 m free drop conditions, a 1/3 linear scale model of the cask was fabricated and tested. The side drop test was planned to assess the effects of the dynamic impact of the cask as part of the safety evaluation. The model was dropped onto a massive steel-faced concrete target from a height of 9m. The objective of the test was to obtain deceleration and displacement information for the cask and shock absorbing covers, verify the integrity of the cask, and examine the crush behavior of the shock absorbing covers. Finite element analysis was performed by using a three-dimensional element model to understand the dynamic behaviors of the cask during the 9 m side drop. The three- dimensional analysis was to evaluate the structural integrity of the model cask. This paper describes the test and analysis results on the simulated model.
