Abstract

As the risk of the various external risk was increased, a study on the integrity assessment of the nuclear transport cask was needed. In this paper, an integrity assessment of the nuclear transport cask under the ballistic impact was studied. The projectile with L/D = 5 was used in simulation. The applied head shapes of the projectile were five types such as flat shape, conical shape, hemispherical shape, truncated conical and sliced flat shape, respectively. The range on the velocity of the projectile was 85 m/s to 680 m/s. The cask body of the nuclear transport cask was not penetrated by the projectile speed up to Vprojectile = 510 m/s. As the cask body was penetrated by the all types projectile with Vprojectile = 680 m/s and the cask lead in the nuclear transport cask was collided with the projectile. As the projectile moved to 31.3 mm in the cask lead, the cask lead was not penetrated by the projectile with Vprojectile = 680 m/s. The integrity assessment on the nuclear transport cask under ballistic impact up to Vprojectile = 680 m/s was obtained.
