HI-STAR 180 ‘Aircraft Crash Test’

On August 28, 2013 Holtec International performed an ‘Aircraft Crash Test’ on a scaled model of a HI-STAR 180 transport/storage cask at the United States Army facility, Aberdeen Proving Ground, located in Aberdeen, Maryland.  The purpose of the test was to demonstrate the integrity of the containment boundary after an aircraft crash into a HI-STAR 180 in storage as required by the Swiss Nuclear Regulatory Guidelines.

The U.S. Army’s missile launcher delivers a picture perfect strike to a scaled model of the HI-STAR 180 transport cask, forcing it into a catch box just as intended by Holtec test engineers.

The missile traveled at a velocity exceeding 600 miles per hour, over 17% greater than the target value.  The location of impact was precisely that as determined to impart the maximum stress levels on the containment boundary.

The test was a huge success; all of the body bolts in the containment boundary of the cask remained elastic and there was no breach of the containment boundary.
