Holtec Nuclear Waste Cask Survives Direct Hit By Missile in Test

When the Swiss government asked for proof that a Holtec International storage container for spent nuclear fuel could survive a plane crash, the company obliged – by shooting a missile at it.

During a recent test at the Army's Aberdeen Proving Ground in Maryland, a scaled model of the HI-STAR 180 transport cask withstood a direct hit from a missile set up specifically to inflict maximum stress on its containment boundary. Moving more than 600 miles per hour, the missile satisfied Swiss regulators' requirements to simulate an aircraft impact but failed to breach the container.

The successful test is good news for the company's Pittsburgh manufacturing plant, which will build 14 of the casks for the Swiss market once granted formal approval. The HI-STAR 180 was licensed in the U.S. in 2009 to transport high-burn-up pressurized water reactor fuel and MOX. According to Holtec, its design also meets the International Atomic Energy Agency's requirements for a type B(U)F cask.

    What type of warhead was used on the missile? If it was just an empty nosecone, what does that show? Let's try this again with a depleted uranium round.

    It is not meant to show what happens if shot with a missle, it's meant to show what happens if a plane hits it. What airplane has a depleted uranium nose cone?

    A missle dose not have a deplated urnaium nose cone anyway...its filled with high explosives. Generally tank rounds are depleted uranium rods and I don't see that as being the request of the test. The missle would have had a much greater impact pressure than a plane as ouside of the engines its just tires and aluminum...could have just used an air compressor and a few pop cans to do the same thing.

    The word "missile" does not mean an explosive device in this case. "Missile testings" is commonly used in many industries for testing large object thrown at a structure. This is done to see how an object holds up in things like hurricanes and tornadoes. For this test, it is to see how a small fighter jet would hold up. They shoot a "missile" of the same material or hardness as a jet (aircraft Aluminum) at the cast at the same speed as a jet would fly.
