Obsolete cask program: oblique and center-of-gravity drop tests

The Heavy-Water Component Test Reactor cask was subjected to two impact tests that involved 9-m drops onto a solid, essentially unyielding surface. The cask, weighing about 21,000 kg, was dropped at an oblique angle to the pad (the longitudinal axis at an angle of 300 from the horizontal). The cask was later dropped at an angle (110 from the vertical) so that the center of gravity was directly over the point of impact. The hoisting equipment at the Tower Shielding Facility (TSF) was used to make the drops. Deformation of the cask and accelerations at several points were predicted, and values were compared with test results obtained from an extensive instrumentation system. Predicted cask deformations agreed reasonably well with the measured values
