Definitions

  • the hollow body of the container has, at least at one of its ends, an opening allowing to access the cavity, to introduce and extract the container containing the fissile material. Under normal conditions of transport, this opening is closed by a closure device such as a bolted cap.
  • Criticality risk prevention also requires containment of fissile material. This function is provided by all the elements of the container that delimit the closed volume that can be occupied by the fissile material. This set of elements forms what is called the "confinement enclosure" of the container.
  • the containment enclosure is constituted by the container which contains the fissile material in bulk, closed by its cap, a violent impact producing a large deformation of the container has no consequence on the confinement of said fissile material .
  • this material is high density polyethylene.
  • thermomechanical protective cellular material is phenolic foam.
  • the container 12 mainly comprises an outer casing 26 and an inner well 28 delimiting the cavity 14. These two components are separated by a space filled with a thermomechanical protective cellular material.
  • the outer casing 26 is constituted by a metal sheet, preferably made of stainless steel.
  • This sheet comprises a cylindrical portion of constant diameter and a generally flat bottom portion.
  • the upper end of the aforementioned cylindrical part is open and equipped on its inner face with the female part 32 of a bayonet mechanism.
  • the upper end of the inner well 28 is open, so as to allow the introduction of the container 10 into the cavity 14 and its extraction, when the organs which normally ensure the closure of the container 12 are removed.
  • the cap 40 of the container 12 has the outer shape of a disc. It comprises a perforated plate 56, placed between an upper thermomechanical protection layer 58 and a lower thermal protection layer 60. A metal jacket 62, preferably made of stainless steel, envelops the assembly thus formed.
  • the perforated plate 56 has the function of damping the shocks radially applied to the outer casing 26 of the container 12, at the access opening provided in the upper part thereof.
  • the damping is obtained by a controlled deformation of the plate 56 in the radial direction, made possible by the presence of the perforations. It results in a controlled ovalization of the upper part of the container 12, without breaking the confinement of the container 10.
  • the containment device makes it possible to ensure in a simple way the maintenance of the confinement of the uraniferous fissile materials in bulk which it contains, in all the circumstances provided for by the most stringent regulations. This result is achieved by the joint use of an inner container impervious to the finest powders, thus constituting a containment chamber for said materials, and a container whose design avoids a deformation of the container likely to to break said confinement.
