Abstract
A container for transport and storage of highly radioactive material, the container being made of thick metal and comprising a tube having an internal wall and a base having a lateral wall, the base being non-removably sealed to one end of the tube, and the internal wall and lateral wall forming a right cylinder with circular cross-section in contact with each other. The base is fixed to the container by shrink fitting the lateral wall with a portion of the internal wall in contact with the lateral wall, the base being disposed such that the lateral wall is entirely inside the tube with a portion of the internal wall comprising an opposed shoulder which cooperates with the corresponding shoulder in the lateral wall. A first continuous seam weld is provided on an external surface of the base in contact with the tube and a second continuous weld seem is provided on an internal surface of the base in contact with the tube.
