    [0001] The present invention relates to the field of transport and storage. radioactive material. It relates more particularly to the transport / storage in horizontal position of a packaging intended to contain radioactive materials. STATE OF THE PRIOR ART A transport / storage package for radioactive materials usually has a lateral body, a bottom and a lid. These parts of the package define a housing cavity for radioactive materials, for example fresh or irradiated nuclear fuel assemblies, or waste cases. In addition, a basket can be arranged within the housing cavity to define compartments in which are placed the different cases / assemblies.
    [0002] For the storage of the packaging at different sites and / or its transport between these sites, the packaging is placed on a support device, on which it rests in a horizontal position. The support device forms an entity in itself, or is integrated with a transport system, road or rail. In any case, this support device is designed to fulfill the mechanical support function of the packaging in a horizontal position, while the cooling function is provided by the outer surface of the packaging forming the exchange surface. In the case of a high power, this exchange surface may also be increased by means of fins arranged at the periphery of the lateral body of this package. With or without fins, there can be encountered a strong spatial heterogeneity of the temperatures, due both to an increase of the thermal load downwards because of the contact of the basket on the inner surface of the cavity, but also to a less efficiency of natural convection at the bottom of the packaging, where the air is still insufficiently accelerated. Thus, even in the presence of the cooling fins, the lower part of the package constitutes a particularly hot zone when the latter rests horizontally on the support device, the distribution of the temperatures being not homogeneous all around the lateral body of the container. packaging. The heat dissipation may not be sufficiently efficient in this hot zone, because the ambient air encounters difficulties to come closer to this zone. This problem is also encountered when the side body is not covered with cooling fins. To limit the extent of this hot zone of the package and its temperature, it may be envisaged to add cooling fins or improve their efficiency. Nevertheless, this requires high development and development costs. Another solution is to lower the authorized thermal power within the package, so that the generated hot zone meets the qualification criteria of sensitive materials constituting packaging, such as neutron resin. Nevertheless, the reduction in the authorized thermal power inevitably leads to a reduction in the amount of radioactive material transportable by the packaging, which has a negative impact on operating constraints. DISCLOSURE OF THE INVENTION The object of the invention is therefore to remedy at least partially the disadvantages mentioned above, relating to the embodiments of the prior art. To do this, the subject of the invention is a device for supporting a transport / storage package of radioactive materials in a horizontal position, the support device comprising a structural base as well as means for supporting the package carried by said structural base from which they protrude upward. According to the invention, the support device further comprises, located at least partly above the structural base, a cooling air guiding fairing 3034246 3 of the packaging by natural convection, said fairing defining a cavity open at the top and in which a part of the packaging is intended to be housed when this packaging is supported in a horizontal position on the device, said fairing comprising, in the lower part thereof, at least one intake opening d cooling air in said cavity. Advantageously, the fairing specific to the invention makes it possible to improve the cooling of the packaging in a horizontal position, at its lower part, thanks to a natural convection effect. The invention is therefore a solution for reducing or even eliminating the hot zone in the lower part of the package, and at a lower cost and without lowering the authorized thermal power. The invention preferably has at least one of the following optional features, taken alone or in combination. Said support means comprise first support means for receiving a head portion of the package, as well as second support means for receiving a bottom portion of the package, said first and second support means being spaced axially from an axial spacing distance (Dea), and the air guiding fairing preferably has an axial length (La) substantially identical to the axial spacing distance (Dea). Said fairing has a first axial end fixed to said first support means, as well as a second axial end fixed to said second support means. Alternatively, or simultaneously with the fixing solution on the support means which has just been mentioned, said fairing is fixed to said structural base of the support device.
    [0003] The axial spacing distance (Dea) is between 1.5 and 4 m. Said fairing has a generally semi-cylindrical shape, pierced with said at least one cooling air intake opening. For example, the cross section of said fairing has a generally semicircular shape.
    [0004] In another example, the cross section of said fairing has a generally semi-octagonal shape, the side closest to the structural base is arranged parallel to the horizontal direction. Preferably, the axial and vertical median plane of the support device, orthogonal to the cross section plane of the fairing, constitutes a plane of symmetry for the fairing. Advantageously, thanks to the inclined side of the semi-octagonal section, the fairing can suck up a larger amount of air and facilitate the gradual descent of the cold air downwards. In addition, the structure of semi-octagonal shape has the advantage of moving closer to a cylindrical shape and thus makes it possible to obtain a cooling air channel of approximately constant thickness, while at the same time being less at cost. In the case of the semi-octagonal section, said side closest to the structural base is pierced with said at least one cooling air intake opening. In this regard, it is preferably provided that said at least one cooling air inlet opening is arranged at a low point of the fairing. This advantageously contributes to the improvement of the cooling, because the air flow can flow on or close to the hot low point of the package. Alternatively, the cooling air intake opening can be arranged near a low point of the fairing, and not precisely on the same low point.
    [0005] Said at least one cooling air intake opening extends over the entire axial length (La) of the shroud, and more generally preferably over at least 90% of this axial length of the shroud. Said at least one cooling air inlet opening has a transverse width of between 100 and 500 mm, and is preferably of the order of 300 mm. There is a free space under said fairing, said free space having, at a low point of the fairing, a height under fairing between 50 and 400 mm, and preferably of the order of 200 mm. In this regard, it is noted that in some cases the structural base has spars connecting the support means, as in the case of a conventional chassis. In this case, the low point of the fairing can be below a high point of the side members, that is to say that the fairing is partly arranged in the space defined between the side members, but always with a minimum height under fairing as defined above.
    [0006] Preferably, said undercarriage height is greater than or equal to half the transverse width of the cooling air inlet opening. As an indication, said fairing has a thickness of between 1 and 5 mm, preferably made using a folded sheet, particularly in the case of the generally semi-octagonal section.
    [0007] According to a first application, the support device forms a transport / storage frame of the package, possibly intended to be handled with the package when the latter is supported by the device. In this case, the frame can for example be placed on the platform of a radioactive material transport system, for example the platform of a wagon belonging to a rail transport system 15, or the platform of a trailer belonging to to a road transport system. According to a second application, the structural base forms all or part of a platform of a wagon belonging to a rail transport system, or forms all or part of a platform of a trailer belonging to a road transport system. In this application, the support device according to the invention is directly integrated into the structure of the transport system, so that it is not designed to be handled, but intended to remain permanently on the vehicle of which it is a part integral. The invention also relates to an assembly comprising a transport / storage package of radioactive materials, and a support device as described above, said package being supported in a horizontal position on said device, with a part of a lateral body of the package housed in said cavity defined by the cooling air guiding fairing.
    [0008] Preferably, said package comprises handling journals, and said support means of the device comprise housings each receiving one of said journals. According to another possibility, said support means of the device 5 comprise at least two cradles on which the lateral body of the package rests. Whatever the design adopted, the lateral body of the package preferably has an outer diameter of between 1 and 2.5 m. To improve the draft, the cooling air guiding fairing preferably has two opposite transverse ends, each located on or near a central axial and horizontal plane of the package. Preferably, the inner surface of the fairing and the outer surface of the lateral body of the package define between them a cooling air circulation channel, of average thickness between 50 and 200 mm. In this respect, it is noted that the fairing serves two functions. The first function, which is essential, is to bring fresh air to the bottom of the package. The second function is to circulate the best air around the package, once it entered the fairing. By nature of natural convection, the circulating air is stuck to the side wall of the package. However, the draw is effectively more efficient with a fairing substantially parallel to the side surface of the side body of the package. Also, preferably, it is provided that the inner surface of the fairing and the outer surface of the lateral body of the package define between them a cooling air circulation channel of substantially constant thickness. In other words, these two surfaces are substantially parallel, so as to maximize the suction flow rate, and thereby improve the draft. Finally, the subject of the invention is a system for transporting radioactive materials, road or rail, comprising a support device as described above, said structural base of the support device being attached to a platform of the transport system, or forming all or part of this platform.
    [0009] Other advantages and features of the invention will become apparent in the detailed nonlimiting description below.

DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS Referring firstly to FIGS. 1 to 3, there is shown an assembly 100 according to a first preferred embodiment of the invention, this assembly 100 comprising a package 1 for transport / storage radioactive materials, and a support device 3 supporting the package. In this embodiment, the device 3 takes the form of a transport / storage frame resting for example on the surface of the ground 5. Conventionally, the package 1 is provided with a lateral body 2, which is a bottom and a lid closing an opening of the package opposite the bottom. The bottom and the cover may be covered respectively by two shock-absorbing covers 6 mounted at the ends of the packaging body, as can be seen in FIGS. 2 and 3. The package 1 has a longitudinal axis 8 centered with respect to the body side 2, and through the lid and the bottom of the same packaging. The axis 8 10 is arranged substantially parallel to the frame 3. Thus, when the package 1 rests in a horizontal position on the frame 3, its longitudinal axis 8 is also oriented horizontally. Also conventionally, the package forms an outer envelope of a package and defines a cavity 7 for housing radioactive materials, and possibly a storage basket 9. The radioactive materials may for example be waste cases or the nuclear fuel assemblies 11. The particularity of the invention resides in the design of the transport / storage frame 3, which will now be detailed always with reference to FIGS. 1 to 3. Overall, the chassis 3 comprises a structural base 10, as well as support means 12 of the package carried by the base 10. In this first preferred embodiment, the structural base is made from main longitudinal members 14 extending horizontally in the longitudinal direction of the assembly, as well as from connecting spars 16 connecting the main spars 14 and extending horizontally according to the direct transverse ion of the assembly 100. All the longitudinal members 14, 16 are preferably inscribed in the same plane, corresponding to the plane of the structural base 10. The support means 12 are in turn distributed as first 30 associated support means a head portion 2a of the package, and second support means associated with a bottom portion 2b of the package. More specifically, the first support means comprise two uprights 18a protruding vertically upwards from the structural base, while the second support means comprise two uprights 18b similarly projecting projecting.
    [0010] The first and second uprights 18a, 18b each comprise, at the upper end, a housing 20 receiving a handling pin 22 fitted to the lateral body 2 of the package. Each pin 22 is arranged conventionally projecting transversely from this lateral body 2, whose outer diameter is between 1 and 2.5 m. When this lateral body is equipped with cooling fins 10 at its periphery, this diameter value incorporates the presence of these fins. The axial spacing distance Dea between the first and second uprights 18a, 18b is between 1.5 and 4 m, while the total length Lt of the lateral body 2 is between 2 and 6 m, these values being considered according to the direction of the axis 8, corresponding to the axial / longitudinal direction of the assembly 100.
    [0011] In this embodiment, the space between the first and second uprights 18a, 18b is functionalized, since it incorporates a cooling air guiding fairing 30 of the package by natural convection. This fairing 30 is located at least partly above the structural base 10, and defines a cavity 32 open upwards and in which a portion of the package is intended to be housed when the latter is supported in a horizontal position. on the first and second uprights 18a, 18b. To allow the draft, the fairing 30 comprises, in the lower part thereof, at least one opening 34 for cooling air intake into the cavity 32. This opening 34 is arranged at a low point of the fairing and preferably extends over an axial length 25 identical to the axial length La of the shroud, substantially identical to the axial spacing distance Dea between the first and second uprights 18a, 18b. Indeed, a first axial end 36a of the fairing is fixed on the first uprights 18a, while a second axial end 36b opposite the first is fixed on the second uprights 18b.
    [0012] In this preferred embodiment, the fairing 30 is of generally semi-cylindrical shape, with a cross section of generally semicircular shape, the center of which is on or close to the axis 8. In the case preferred where the opening 34 extends over the entire axial length of the fairing 30, the latter then takes the form of two quarters of a cylinder separated by the opening 34, the transverse width Ltr is between 100 and 500 mm and preferably about 300 mm. In addition, there is provided a free space 38 under the fairing, the low limit of this free space being constituted by the surface of the ground 5 between the main longitudinal members 14. At the low point of the fairing 30, the height under fairing Hsc of this free space 38 is between 50 and 400 mm, and preferably of the order of 200 mm. More generally, for increased efficiency, it is ensured that the height under fairing Hsc is greater than or equal to half the transverse width Ltr of the opening 34 for cooling air intake. The axial and vertical median plane 40 of the assembly 100 passes through the opening 34 longitudinally and symmetrically. On either side of this plane 40, the shroud 30 has two opposite transverse ends 42a, 42b, each located on or near a horizontal and axial median plane 44 of the package 1. The journals 22 equipping the lateral body 2 are also traversed symmetrically by this median plane 44.
    [0013] Referring more specifically to FIG. 3, it is noted that the inner surface of the fairing and the outer surface of the lateral body of the package define between them a cooling air circulation channel 50 of average thickness between 50 and 200 mm. By providing this thickness substantially constant and relatively low, that is to say by applying a parallelism between the two aforementioned surfaces 25 defining the channel 50, the cooling air can indeed circulate at best around the packaging, by natural convection. More specifically, the fairing 30 specific to the invention makes it possible to improve the cooling of the packaging in the horizontal position, at its lower part, by means of a natural convection effect of the air, which penetrates first through the opening 34, before traveling in the channel 50, and then escaping upwards at the transverse ends 42a, 42b of this fairing. The conventionally hot zone in the lower part of the package is thus advantageously reduced in terms of range and maximum temperature, and at a lower cost and without lowering the thermal power allowed within the package. According to another embodiment shown in FIG. 3a, the shroud 30 has a generally semi-octagonal cross-section whose side 54 closest to the structural base 10 is arranged parallel to the horizontal direction, thus parallel to In this embodiment, the axial and vertical median plane 40 of the support device constitutes a plane of symmetry for the fairing 30, while the other median plane 44 delimits upwards the octagonal half-section. The two inclined lateral sides 56 make it possible to suck up a larger quantity of air and facilitate the gradual descent of the cold air downwards. In this embodiment, the thickness of the channel 50 between the shroud 30 and the outer surface of the lateral body 2 is slightly variable because of the difference in geometry between the two elements opposite. Its average thickness nevertheless remains within the range of values mentioned above. The horizontal side 54 closest to the structural base 10 is pierced by the opening 34 of cooling air intake, centered on the same side 54. The fairing 30 is for example made using a sheet metal 1 to 5 mm thick, folded at the angles of the octagonal half-section.
    [0014] According to yet another embodiment mounted in FIG. 3b, the fairing 30 has a first portion 30a similar to the fairing 30 of FIG. 3, in that it has a cross section of generally semicircular shape. Nevertheless, this first portion 30a secured to the uprights 18, 18b has a thickness that increases in a downward direction, to form two longitudinal lower edges 60, each facing another edge 62 formed by a second portion 30a of the fairing, fixed on the structural base 10 at an upper portion thereof. By way of example, the second portion 30b is in the form of a longitudinal structure parallel to the axis 8, and of triangular cross-section so that two of its sides respectively form the two edges 62.
    [0015] 3034246 12 Each pair of songs 60, 62 facing each other forms an opening 34 for cooling air intake, whose orientation can be controlled. Preferably, the opening 34 located vertically close to the low point of the package 1, but on the left side of the median plane 40, is oriented to deliver air to the right 5 in the channel 50, while the opening 34 located on the right side of the median plane 40 is oriented to deliver air to the left in the channel 50. This allows to approach the cooling air closer to the critical low point of the package 1, for a better cooling. According to a second preferred embodiment of the invention shown in FIG. 4, the first and second support means here take the form of two cradles 18a ', 18b' on which the lateral body 2 of the package 1 rests. Cribs can be closed on the top by frames 64 to completely surround the side body of the package, to improve the maintenance of the latter. In this second embodiment, the structural base 10 may be identical or analogous to that of the previous embodiment, or may be in a more solid form, as shown schematically in FIG. 4. The fairing 30 is extends along the same axial length La, also corresponding to the axial spacing distance Dea between the two cradles 18a ', 18b'.
    [0016] Whatever the envisaged design, it is noted that according to a first application mentioned above, the support device 3 forms a transport / storage frame of the packaging, possibly intended to be handled with the packaging when the latter is supported by the device. In this case, the frame may for example be placed on the platform of a radioactive material transport system, for example the platform of a wagon belonging to a railway transport system, or the platform 70 of a trailer 72 as belonging to a road transport system 74, as has been schematized in FIG. 5. Alternatively, as shown schematically in FIG. 6, it is provided that the structural base 10 forms all or part of a platform of a wagon 80 30 belonging to a rail transport system 82, or forms all or part of a platform of a trailer belonging to a road transport system. In this application, the support device according to the invention is directly integrated into the structure of the transport system, so that it is not designed to be handled, but intended to remain permanently on the vehicle of which it is a part 5 integral. In FIG. 6, the wagon 80 is conventionally equipped with an element 86 called "canopy", mounted on the platform 10 of this wagon and intended to cover the assembly 100. This element 86 may be provided in several sliding parts on the platform, and equipped with grids 88 for the introduction and evacuation of air, in particular for the circulation of the cooling air intended to pass through the fairing 30 specific to the invention. Of course, various modifications may be made by those skilled in the art to the invention which has just been described, solely by way of non-limiting examples. 15 20
