Programme to Develop a Large Transport Container for Transportation of Large Pieces of Contaminated Equipment and of Medium Level Waste
A development programme, sponsored by the Commission of European Communities was carried out jointly by Transnubel SA Belgium and by CEA France, with the aim of developing a very large package that complies with IAEA regulations for the safe transport of radioactive materials. The packaging will be used for the transportation of contaminated equipment or waste from various types of nuclear installations. The main difficulty encountered in designing such packaging consists in ensuring the leaktightness of the containment system following a drop from a height of 1 m on to a rigid punch. Most severe damage undoubtedly occurs when a large surface hits the punch after the drop. Most of the drop energy is absorbed by the beam grid structure (245,000 Joules for 1 m drop).
As a first approach, structural deformation was studied in reduced-scale tests. This demonstrated the necessity of reinforcing the beam frame. Work is now in progress to demonstrate that a design incorporating suitable insulating material can also comply with other IAEA regulations, such as that governing a 9 m high drop on an edge followed by a fire at 800°C.
