Definitions

  • the invention relates to the field of packaging for the transport and / or storage of radioactive materials, preferably of the type of irradiated nuclear fuel assemblies.
  • storage devices also called “baskets” or “racks” storage. These storage devices, usually of cylindrical shape and of substantially circular or polygonal section, are able to receive the radioactive materials.
  • the storage device is intended to be housed in the cavity of a package to form together with it a container for the transport and / or storage of radioactive materials, in which they are perfectly confined.
  • the aforesaid cavity is generally defined by a lateral body extending along a longitudinal axis of the package, as well as a bottom and a package cover arranged at opposite ends of the body, in the direction of the longitudinal axis.
  • the lateral body comprises an inner wall and an outer wall, generally taking the form of two concentric metallic shells together forming an inter-wall annular space inside which thermal conductors are housed, as well as radiological protection means, in particular to form a barrier against neutrons emitted by the radioactive material housed in the cavity.
  • This neutron shielding is conventionally carried out using a material called "resin concrete".
  • the thermal conductors make it possible to conduct the heat released by the radioactive materials towards the outside of the container, in order to avoid any risk of overheating which may cause degradation of these materials, an alteration of the mechanical properties of the materials constituting the packaging, or else an abnormal rise in pressure in the cavity (see, for example, J2003240890).
  • Thermal conductors have been the subject of many developments, which have led to various achievements.
  • One of the most commonly used resides in the placement of fins in the inter-wall space, so that their opposite ends are respectively in contact with the two rings in order to create thermal bridges.
  • These fins which extend in length in the direction of the longitudinal axis of the package, and allow to conduct the heat of the inner shell to the outer shell.
  • radiological protection blocks between the fins in the inter-wall space of the lateral body.
  • each thermal conductor comprises at least one member for traversing the inter-wall space, and at one end of this passage member, a first support member and fitting on one of the walls. inner and outer side packing body. Generally, at the other end of the conductor, there is provided a second support member and connector on the other of the two walls.
  • Each support and coupling member also has a plurality of attachment points on its associated wall of the lateral packaging body, these attachment points usually taking the form of through holes for fixing screws on the walls of the body. lateral.
  • the thermal conductors and the walls of the lateral body are generally made of materials having different coefficients of thermal expansion.
  • the conductors are generally made of copper, aluminum or their alloys, and the inner and outer walls of steel. Consequently, the mounting made at the fixing points must be able to take into account the phenomena of differential thermal expansion between these elements, without generate mechanical stresses likely to alter their mechanical connection.
  • the assembly must avoid any deformation of the support member which could affect the good contact of this body with the wall on which it is attached, and thus compromise the heat transfer between the wall and the conductor.
  • the invention therefore aims to at least partially overcome the disadvantages mentioned above, relating to the achievements of the prior art.
  • the subject of the invention is a packaging for transporting and / or storing radioactive materials, comprising a lateral body equipped with an inner wall and an outer wall defining between them an inter-wall space in which is arranged at least one thermal conductor, the inner wall defining a housing cavity for the radioactive materials, said thermal conductor comprising at least one member for traversing the inter-wall space, and, at one end of this passage member a first support and coupling member on one of said inner and outer walls of the lateral packaging body, said first wall, said first support and coupling member having a plurality of first fixing points on the first wall of the lateral packaging body, said first fixing points being spaced from each other in a longitudinal direction of the thermal conductor.
  • said first support member and coupling member is segmented in said longitudinal direction, so as to define first segments spaced apart from each other by first slots arranged between said first attachment points, each first slot extending through said through member defining a closed end of said first slot.
  • the first segments can expand without constraint on either side of their attachment points, towards their ends, by consuming the width of the slots forming gaps between the segments.
  • the proposed solution no longer requires the presence of oblong holes as in the prior art, and above all allows a firm attachment of the attachment points on their respective walls, for obtaining a better heat transfer.
  • the invention is therefore no longer subject to the antagonistic effects resulting from the tightening of the screws at the attachment points, as was the case previously.
  • the ratio between the width of each first slot and the length, in the longitudinal direction, of any one of the first two segments arranged on either side of this slot is between 0.005 and 0.1.
  • each first slot extends through the passage member at a distance which represents 40 to 90% of the total width of the passage member in the direction of the slot.
  • each first slot extends substantially orthogonal to the longitudinal direction of the thermal conductor. These slots could nevertheless be inclined differently, without departing from the scope of the present invention.
  • said first support member and coupling member and said traversing member are each of substantially flat shape, parallel to the longitudinal direction. These two elements are preferably intersecting, for example forming a V with an internal angle of between 90 and 150 °.
  • a second support member Preferably, at the other end of said bushing member, there is provided a second support member, and possibly a coupling, on said other of said inner and outer walls of the lateral packaging body, said second wall.
  • the second support member is in the continuity of said traversing member, sandwiched between two sectors of the second wall, here in general the outer wall of the main body.
  • said second support member is segmented in said longitudinal direction, so as to define second segments spaced from each other by second slots each extending through said passage member defining a closed end of said second slot.
  • these second slots provide more flexibility to the support member clamped between the sectors of the second wall, and thus improve the overall flexibility of the thermal conductor.
  • the second support member is supported on a surface of said second wall defining the inter-wall space, and possibly connected thereto.
  • the conductor then preferably has a section in the overall shape of S or Z, with projecting angles between the traversing member and each of the two support members preferably between 90 and 150 °.

  • the second support member could be continuous, that is to say without slot, without departing from the scope of the invention.
  • the second slot solution is in particular retained when the second support member has a plurality of second attachment points on the second wall of the packaging side body, said second attachment points being arranged between the second slots separating the second segments. .
  • the benefit of these second slots is then comparable to that of the first slots, as described above.
  • This embodiment can therefore comprise either two first support members and a second support member, or two second support members and a first support member, these support members being in both cases connected by the two crossing bodies.
  • the second support members may or may not have second attachment points, depending on the desired needs.
  • each first support member can be attached to the inner wall or the outer wall of the packaging side body
  • shape of ⁇ (uppercase omega) is crossed by slots each running through a part of each of the two crossing members, through the support member which connects them. These slots thus take a general shape of U contributing to obtaining a great flexibility of the thermal conductor.
