Definitions

  • the present invention relates to the field of transport and / or storage of radioactive materials, such as nuclear fuel assemblies, fresh or irradiated.
  • the invention relates to a package comprising a radiological protection device arranged between two concentric rings, forming a barrier against gamma radiation.
  • storage devices are used, also called “basket” or “rack” storage.
  • These storage devices usually of cylindrical shape and of substantially circular section, have a plurality of adjacent housings each adapted to receive a nuclear fuel assembly.
  • 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 nuclear fuel assemblies, in which the nuclear material is confined.
  • the aforementioned cavity is generally defined by a lateral body extending in a longitudinal direction of the package, this lateral body comprising for example two concentric metal ferrules jointly forming an annular space inside which is housed a radiological protection device, in particular to form a barrier against gamma radiation emitted by the fuel assemblies housed in the cavity.
  • the radiological protection device is made using several prefabricated elements made of lead or in one of its alloys, distributed around the cavity, in the appropriate annular space defined by the two metal ferrules.
  • each of these elements is inserted between the two ferrules, in a longitudinal insertion direction.
  • a mounting clearance must be provided to allow such insertion, this game resulting in a discontinuity of material in the lateral body of the package, in the radial direction in which the inner ring is successively arranged, the protective elements radiological, and the outer shell.
  • the discontinuity of material observed has the effect of a considerable decrease in the thermal conductivity of the lateral body of the package, implying a low capacity of the latter to evacuate the heat produced by the fuel assemblies.
  • the gaps between the radiological protection elements and the ferrules may be reduced by decreasing manufacturing tolerances, but it is nevertheless very expensive, and does not by any means to eliminate discontinuities matter.
  • Another solution consists in separating the radiological protection function from the thermal conduction function, this being then fulfilled by means of additional elements of the fin type connecting the two ferrules, arranged alternately with the radiological protection elements in the radiator. annular space. Nevertheless, this further complicates the design of the package, and also requires the use of special techniques to ensure that the fins are in contact with each of the two side body ferrules.
  • 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 package for transporting and / or storing radioactive materials, said package comprising a lateral body extending around a longitudinal axis of said package, said lateral body forming a cavity of housing of radioactive materials and comprising an inner metal ferrule and an outer metal ferrule, the two ferrules being concentric and jointly forming an annular space within which a gamma radiation barrier radiation protection device is housed, said radiological protection device comprising at least first and second radiological protective metal elements adjacent in a circumferential direction of the packaging.
  • said first element bears against the outer shell and at a distance from said inner shell, while said second element bears against the inner shell and at a distance from said outer shell.
  • said first and second elements are in contact with each other in an interface taking, in section along any plane orthogonal to the longitudinal axis and passing through this interface, the shape of a line segment defining with a radial line crossing it in the middle an acute angle (A).
  • the invention thus offers a clever design allowing the radiological protection elements to conduct heat satisfactorily between the two ferrules. Indeed, the heat is conducted continuously first between the inner ferrule and the second radiological protection element, by the contact between these parts, then through the interface between the first and second elements, and finally between the first radiological protection element and the outer shell, still due to the expected contact between these parts.
  • the particular geometry and layout of the radiological protection elements allow to confer on the lateral body of the packaging a satisfactory thermal conductivity.
  • the presence of helium or thermal conduction fins is therefore no longer necessary, which makes it possible to present a packaging of simplified design and manufacture.
  • first and second radiological protection elements are no longer intended, as in the prior art, to approach closer to each of the two ferrules, but each being only in contact with one and remotely on the other of the two ferrules, the manufacturing tolerances of these elements can be increased. This advantageously results in a significant cost reduction.
  • one and / or the other radiological protection elements can be coated with a heat conductive layer at the contact interface, to further improve the thermal conduction between these elements.
  • This layer is preferably thin, and deformable, for example made of lead or in one of its alloys.
  • this heat conducting layer solution can also be adopted at the contacts between the radiological protection elements and the ferrules.
  • said angle (A) is between 30 and 60 °, and more preferably, is close to 45 °.
  • the interfaces thus inclined allow a satisfactory radial plating of the radiological protection elements, when these are circumferentially constrained.
  • said interface is plane.
  • the package comprises at least one first metal radiological protection element and two second metal radiological protection elements arranged on either side of said first element in the circumferential direction, said first element being in contact with each of the two elements.
  • second elements respectively according to two interfaces each taking, in section along any plane orthogonal to the longitudinal axis and passing through this interface, the shape of a line segment defining with a radial line passing through it in the middle an acute angle (A) , the two line segments being respectively supported by lines approximating one of the other going radially inward and intercepting between the two radial lines.
  • the first element is solicited by the two second elements, which therefore participate jointly in its plating against the outer shell.
  • this first element participates in the plating of the second two elements against the inner shell.
  • the package preferably comprises at least one second metal radiological protection element and two first metal radiological protection elements arranged on either side of said second element in the circumferential direction, said second element being in contact with each of the first two elements respectively according to two interfaces each taking, in section along any plane orthogonal to the longitudinal axis and passing through said interface, the shape of a line segment defining with a radial straight line crossing it in the middle an acute angle (A), the two line segments being respectively supported by lines approaching one another radially outwardly and interposed between the two radial lines.
  • A acute angle
  • first and second elements arranged alternately in the circumferential direction, and cooperating in the aforementioned manner, namely that each of them is solicited by its two adjacent elements, which jointly participate in its plating against its associated ferrule.
  • each first radiological protection element has a section, in any plane orthogonal to the longitudinal axis, in the overall shape of a trapezium whose large base bears against the outer shell and the small base at a distance from the inner shell
  • each second radiological protection element has a section, in any plane orthogonal to the longitudinal axis, of overall shape of trapezium whose large base bears against the inner ferrule and the small base remote from the outer ferrule, and the faces of the first and second elements defining the sides of the trapezoids are in contact two by two, so as to form said interfaces.
  • first elements could adopt a form different from that of the second elements, just as different forms could be adopted within the first / second elements.
  • other forms envisaged are for example the triangle, or the truncated trapezium at the two corners between the large base and the sides.
  • the large base is intercepted, locally in the middle, orthogonally by a radial line.
  • each trapezoid is isosceles.
  • each trapezium is preferably straight, and even more preferably in the form of a circular arc of diameter identical to that of the ferrule surface that it contacts, in order to increase the contact area between these two elements.
  • the ratio of lengths between the large base and the small base is between 3 and 8. The larger the ratio, the more effective the heat transfer.
  • each of said plurality of first and second elements is maintained only by contacts in the annular space. This implies, in particular, that no additional fastening means is reported between a protective element and its associated shell, or between two directly consecutive protection elements.
  • the design allows these elements to maintain each other by contact, also using ferrules. This possibility is also offered for protection elements with a shape different from that of the trapezoid.

  • each of said plurality of elements fixedly mounted on its associated shell has a decreasing section in a given direction of the longitudinal direction of the package, and each of the plurality of the other elements has a section increasing in said given direction of the longitudinal direction.
  • the intensity of the contacts is therefore dependent on the longitudinal relative position between the elements. Consequently, when one of the longitudinal sliding protection elements is inserted between its two associated fixed protection elements, the contacts between the elements, once established, have an intensity that increases as one continues insertion.
  • the subject of the invention is also a method for manufacturing a package as described above, in which each first and second radiological protection metal element is inserted into said annular space, and then a clamping is carried out. to constrain these elements in the circumferential direction.
