High energy shock absorbing wall structure and container using same

摘要

The shock-absorbing wall structure can be used to equip transport containers which may suffer major falls, generating very high energy on impact. It is chiefly made up of several layers of a cellular bearing structure (7, 7N, 7N+1 . . . ) in which some metal blocks are regularly placed. These blocks are positioned in staggered manner from one layer to another, so as to leave regular spaces in which they can expand in the event of impact. Particular application to transport containers such as fuel rods from nuclear plants or so-called type C containers (Transport Regulations for Hazardous Materials-Edition 96-IAEA Document, Vienna).
