Definitions

  • the invention relates to a packaging or container for transporting or storing nuclear fuel assemblies, said packaging comprising a forged metal body, generally made of forged steel, delimiting a cavity into which the assemblies are introduced.
  • the invention also relates to the means of achieving it.
  • Nuclear fuel assemblies are generally prismatic or cylindrical in shape, often with a square section (eg PWR, BWR, ...), sometimes a hexagonal section (VVER, %), sometimes a circular section (CANDU, RBMK ,. ..).
  • a problem for the packaging designer is to manage to accommodate the maximum number of assemblies in the cavity of the packaging while respecting the regulations in force; in particular the packaging must have:
  • the weight of the packaging and its size must be limited to be compatible with the equipment of the installations to serve (reactors, intermediate storage facilities, reprocessing plants, means of transport).
  • the Applicant has sought to develop packaging having a saving in weight and size compared to the quantity of fuel assemblies housed therein, while satisfying the conditions of shielding, thermal conductivity and mechanical strength. required. DESCRIPTION OF THE INVENTION
  • the invention is a package for nuclear fuel assemblies as described in the appended claims.
  • the packaging according to the invention therefore has a metallic cylindrical body whose cross section is not circular.
  • said cross section has the appearance of a crown, the interior and exterior perimeters of which do not have the shape of a circle but generally contain segments of straight lines; the perimeters can for example have the shape of squares, or other regular, concentric polygons whose angles can be rounded.
  • the thickness of the metallic cylindrical body with a non-circular cross section according to the invention is sufficient in all respects to ensure shielding in accordance with the specifications. It generally reaches several tens of centimeters.
  • the shape of the interior cavity can be adapted to the type of fuel assemblies to be housed there.
  • the assemblies have a square cross section
  • a cavity having a square or rectangular cross section with generally rounded corners is preferably chosen; this increases its filling coefficient (less dead space than in a circular section cavity).
  • the cavity located inside the metallic cylindrical body is generally closed at its two ends, one of them by a bottom fixed for example by welding with or without shrinking, the other by a removable cover.
  • the starting ferrule with circular section to be modified to end up with the cylindrical body according to the invention is generally based on forged steel.
  • cylindrical body of the packaging according to the invention is of the same nature.
  • Figure 1 illustrates a package according to the invention and shows the cross section.
  • FIG. 2 illustrates a detail of the method of fixing by screw of a lunula on the internal wall of the cylindrical body.
  • the dimensions of the flats and the lunules can vary and be adapted to the assemblies to be stored in the cavity 2, while ensuring that the thicknesses of the cylindrical body 1 meet the requirements for shielding and mechanical strength.
