Definitions
- the present invention relates to a container for the storage / transport of non-irradiated radioactive materials such as fresh nuclear fuel assemblies, intended to constitute the energy source of nuclear power plants.
- the containers for non-irradiated radioactive materials are of substantially cylindrical or parallelepiped shape.
- These containers usually include an outer packaging, consisting of one or more side faces, a fixed bottom, a cover, and one or more removable protective covers.
- Each of the elements constituting the packaging, and more particularly the side face (s) of the latter, is composed of a single layer or of a stack of layers made of various materials.
- the side (s) of the packaging are • in the form of a stack of layers, this . last one has a layer from the inner end, generally taking the form of a metal plate.
- the metal plate (s) form an internal lateral wall of the packaging, the latter defining a cavity inside which the radioactive materials are able to be housed.
- the cavity defined by the lateral internal wall is substantially cylindrical with a circular section. It is also specified that the cavity is completely closed by means of the fixed bottom and the cover of the packaging, situated respectively at the ends of the lateral internal wall.
- Non-irradiated radioactive materials such as fresh nuclear fuel assemblies composed for example of a mixture of uranium and plutonium oxides, extend longitudinally and have a square section.
- the latter In order to precisely position these assemblies in the container cavity, the latter also has a main structure of usually substantially cylindrical shape of circular section, this structure defining a plurality of housings each capable of receiving at least one fuel assembly.
- the main structure also called “basket” or “rack” for storage, is then designed so that it can be introduced into the cavity of the packaging, so as to be held there in relation to the packaging, once inserted .
- the main structure generally has .a diameter substantially identical to inside diameter of the lateral internal wall of the package, to the clearance.
- the main structure can then be in the form of discs spaced or stacked on each other, along a longitudinal main axis of the container.
- the discs generally each comprise a plurality of orifices.
- each orifice can be traversed by a tube designed to receive one or more assemblies of nuclear fuel.
- the main structure is positioned in the cavity of the packaging so that the clearance between the main structure and the lateral internal wall is low or zero, in order to ensure satisfactory heat exchanges between these two components of the container.
- the stacks of layers making up the container packaging have been the subject of numerous studies, in particular to meet the needs specific to the tests concerning the fall on a punch and the fall from 9 meters, these tests must be passed in an order such that it provides the maximum damage.
- the punching test consists in raising the container one meter above a cylindrical punch fifteen centimeters in diameter, then dropping it by gravity on the punch. To pass this test as well as that of falling from nine meters, it is necessary to demonstrate that the main structure of the container, that is to say the basket in which the nuclear fuel assemblies rest, does not undergo any deformation.
- multi-layer packaging there are first known stacks with anti-punch armor comprising three elements superimposed on each other. To achieve such stacks, the elements are positioned so that an external plate and an internal steel plate sandwich a fire-resistant layer, the latter being made of a material with low crushing stress making it possible to absorb the falling energy .
- the object of the invention is therefore to propose a container for the storage / transport of non-irradiated radioactive materials such as nuclear fuel assemblies, the container comprising a main structure and a package comprising a lateral internal wall defining a cavity inside. which is able to accommodate the main structure, the container at least partially overcoming the drawbacks mentioned above relating to the embodiments of the prior art.
- the object of the invention is to present a container whose design makes it possible to meet regulatory safety requirements relating to the transport / storage of nuclear materials, while having a total mass which is greatly weakened compared to the containers of the prior art, in order to comply with ever greater operating constraints.
- the subject of the invention is a container for the storage / transport of non-irradiated radioactive materials such as nuclear fuel assemblies, the container comprising a main structure and a package comprising a lateral internal wall defining a cavity at the inside of which the main structure is capable of being housed, the latter defining a plurality of housings each capable of receiving at least one fuel assembly.
- the container further comprises spacer means of the main structure with respect to 'packaging, spacing means being able to avoid any direct contact between the lateral internal wall and the main structure, so as to allow a punctual deformation of this lateral internal wall of the packaging during a punching test.
- the specific design of the container according to the invention results from an approach completely different from the conventional approach previously practiced for designing such containers.
- the main condition for satisfying the regulatory safety requirements relating to the transport / storage of nuclear materials being to demonstrate that the main structure containing the fuel assemblies is not damaged following the various drop tests of the container, this technical constraint has always been interpreted as a need to preserve the lateral internal wall of the packaging intact, following the implementation of these various tests.
- the invention has been made by departing from this conventional practice, by providing a package whose lateral internal wall is capable of deforming in a punctual manner following mechanical stresses exerted on the packaging externally, such as those exerted by a punch during the punching test. So that a deformation of the lateral internal wall does not damage the main structure of the container, unlike all the containers of the prior art, no direct contact has been provided between this lateral internal wall and the main structure, so that the deformation cannot be transmitted.
- the main structure of the container containing the fuel assemblies is able to remain intact following the completion of the various drop tests, despite the deformation of the lateral internal wall of the packaging caused. Consequently, the design of this package can then be considerably simplified. Indeed, the specific design retained for the container according to the invention allowing the lateral internal wall of the packaging to be deformed during the drop test on punch, this packaging no longer needs to be produced using 'complex stacks of oversized layers, and can therefore undergo large simplifications as well as a significant reduction in mass and thickness compared to previously offered packaging.
- the means for spacing the main structure relative to the packaging are provided between the main structure and the lateral internal wall of the packaging, the spacing means having '' a fuse function mechanical in order to deform during a punctual deformation of the lateral internal wall of the packaging, occurring following the punching test.
- the spacing means are also designed to resist, and therefore not to deform, following the mechanical stresses encountered during falls from 9 meters.
- the space provided between the lateral internal wall of the packaging and the main structure is at least partially filled by the spacing means, so as to provide an additional function of heat transfer between these elements. Note that this function is made possible due to the small or zero clearance existing between on the one hand the spacing means and the main structure, and on the other hand the lateral internal wall of the packaging and these same means of spacing.
- the spacing means are advantageously designed to fulfill the role of a mechanical fuse during a fall on a punch, the latter generally causing a punctual deformation of the lateral internal wall of the packaging.
- the spacing means are directly damaged under the effect of the deformation of the lateral internal wall, without transmitting this deformation to the main structure of the container, which remains completely intact.
- the spacing means are also designed not to deform during the 9 meter drop tests, more particularly during horizontal falls, under the inertia of the main structure responsible for fuel assemblies.
- the spacing means are designed so as to be able to fully fulfill the functions of a mechanical fuse, even when the falls on a punch are made after the falls from 9 meters.
- the spacing means are composed of a plurality of deformable sectors distributed around the main structure of the container, these sectors extending over the entire length or only over part of the length of the main structure of the packaging. , or being stacked on top of each other in a direction parallel to a longitudinal main axis of the container.
- the deformable sectors are arranged next to each other so as to form strips encircling the main structure.
- the deformable sectors are made of a material with low crushing stress such as wood, plastic foam or honeycomb confined between two metal sheets, or still metallic elements taking the form of two concentric sheets separated by reinforcements.
- the metal elements are preferably made of aluminum or one of its alloys.
- the deformable sectors are fixed to the main structure of the packaging, and completely or only partially cover the main structure of the container.
- the means for spacing the main structure relative to the packaging are provided on a cover and / or a fixed bottom of the packaging, the lateral internal wall of the packaging and the main structure being separated by an empty space.
- This solution remains very advantageous insofar as it makes it possible to obtain a relatively light container, due to the absence of material between the lateral internal wall of the packaging and the main structure.
- the main structure of the container has a substantially cylindrical shape of circular section, and the inner side wall of the package and the main structure are separated by a form space. substantially annular.

- FIG. 1 we see a container 1 for the storage / transport of non-irradiated radioactive material such as fresh nuclear fuel assemblies (not shown) ' , according to a first preferred embodiment of the present invention.
- the container 1 comprises a packaging 2 as well as a main structure 4 of the basket type, capable of being housed inside the packaging 2 of the container 1.
- the package 2 consists of a side face 6 of substantially annular shape, a fixed bottom 8, a cover 10, and two removable protective covers 12 and 14 arranged at the ends of the package 2.
- the side face 6 of the package 2 is unique, but could of course be composed of several elements attached to each other, without departing from the scope of the invention.
- This lateral face 6 is composed of an internal ferrule 16 and an external ferrule 18 centered on a main longitudinal axis 19 of the container 1, these ferrules 16 and 18 being spaced and held relative to one another by the 'through stiffeners 20, which also have the function of conducting heat through a neutron protection 22, also located between the two ferrules 16 and 18.
- the internal ferrule 16 of the lateral face 6 of the package 2 has a lateral internal wall 24, defining a cavity inside which is able to be housed the main structure 4 of the container 1. As can be seen in Figures 1 and
- the main structure 4 resting in the cylindrical cavity defined by the lateral internal wall 24 comprises a plurality of housings 26, each capable of receiving an assembly of fresh nuclear fuel.
- the main structure 4 of the container 1 preferably has a substantially cylindrical shape of circular section, and can be produced according to known conventional techniques.
- the structure 4 is obtained by a stack of discs 28 along the longitudinal main axis 19 of the container 1. A plurality of orifices made on each of the discs 28 allows thus defining the housings 26, into which the nuclear fuel assemblies may be introduced.
- the container 1 also comprises means for spacing the main structure 4 relative to the packaging 2, the spacing means being able to avoid any direct contact between the lateral internal wall 24 and the main structure 4, so as to allow a specific deformation of this lateral internal wall 24 of the package 2 during a punching test.
- the spacing means 30 are provided between the main structure 4 and the lateral internal wall 24 of the package 2, in order to ensure in particular a heat transfer function between the elements 2 and 4.
- the main structure 4 indeed has an outside diameter smaller than the diameter of the lateral internal wall 24, this specific design of the container 1 resulting in the formation of a space of substantially annular shape. , inside which the spacing means 30 can be accommodated.
- the particular arrangement of the spacing means 30 can then allow these means to fulfill a mechanical fuse function allowing punctual deformations of the internal lateral wall 24 of the packaging 2. This function will be more fully explained below.
- the spacing means 30 consist of a plurality of deformable sectors 32, distributed around the main structure 4, on which they are preferably assembled by screwing.
- the deformable sectors 32 can first of all extend over substantially the entire length of the main structure 4, as shown by the strip 34. Furthermore, the deformable sectors 32 can also be stacked on top of each other in a direction parallel to the main longitudinal axis 19 of the container 1, as shown by the strip 36.
- deformable sectors 32 can also be arranged one beside the other so as to form annular bands (not shown) encircling the main structure 4 and distributed over the entire length of this structure 4 or only at the two ends thereof.
- the diversity of arrangements of the deformable sectors 32 on the main structure 4 is very large, and can lead to total or partial covering of the main structure 4 of the container 1.
- the location of the sectors 32 on the structure 4 can therefore be judiciously chosen, in order to best respond to the mass constraints and the mechanical constraints to be met by the container 1.
- each deformable sector 32 consists of a metallic element preferably made of aluminum or one of its alloys, this element taking the form of two concentric sheets 40 and 42 of identical axis to the main longitudinal axis 19 of the container 1, the sheets 40 and 42 being separated by reinforcements 44 ( Figure 3).
- the metal elements constituting the deformable sectors 32 are extruded, but could also be produced by mechanical welding or any other conventional technique, without departing from the scope of the invention.
- the sheet-like parts 40 and 42 are respectively in contact with the main structure 4, and the lateral internal wall 24.
- the elements 40, 42 and 44 each have a lower thickness. about half the thickness of the inner shell 16.
- the reinforcements 44 each extend over the entire length of the sheet-shaped parts 40 and 42, and are inclined with respect to a radius of circle concentric with the sheet-shaped parts 40 and 42.
- the reinforcements 44 are arranged so that two successive reinforcements 44 are inclined in an opposite direction, so as to be in phase opposition.
- the angle of inclination of the reinforcements can be around ⁇ 20 °.
- the deformable sectors 32 can take any other form and be formed using other materials, insofar as these are capable of spacing the main structure 4 from packaging 2,. and likely to fulfill the role of mechanical fuse described below. Still by way of nonlimiting example, the deformable sectors 32 can then be made of a material with low crushing stress such as plastic foam, honeycomb, or wood such as balsa, confined or not between two metal sheets.
- the packaging 2 of the container 1 comes into contact with a punch 46 of approximately 150 mm in diameter, this punch 46 causes significant local mechanical stresses on the packaging 2, so that the lateral face 6 is deformed over its whole thickness in an area located opposite the punch 46.
- the packaging 2 is preferably designed so that following such a punching test, the internal shell 16 of this packaging 2 is deformed but not perforated. In this way, the internal shroud 16 of the packaging 2 is deformed by penetrating into the annular space of axis 19 initially provided between the internal lateral wall 24 and the main structure 4 of the container 1, this annular space being occupied by the spacing means 30.
- the deformable sector or sectors 32 of the spacing means 30 located opposite the deformation of the lateral internal wall 24 then play their role of mechanical fuse by degrading directly following the impact of the lateral internal wall 24, without transmitting the deformation to the main structure 4 of the container 1. It is also indicated that the deformation of the lateral internal wall 24 takes place as if no element existed between the structure 4 and this lateral internal wall 24.
- the sectors 32 are designed so that their deformation energy is negligible compared to the energy involved when falling on the punch 46, largely absorbed by the point deformation of the side face 6 of the package 2.
- the sheet metal part 42 is deformed under the effect of the deformation of the lateral internal wall 24.
- the reinforcement 44 located near this deformation are also deteriorated, always so that the deformation of the lateral internal wall 24 is not transmitted to the main structure 4 of the container 1.
- the deformable sectors 32 do not necessarily follow the entire surface of the internal wall lateral 24, it is therefore possible to encounter cases in which the deformation of this lateral internal wall 24 is located in an area devoid of spacing means 30, and therefore of deformable sectors 32.
- the lateral internal wall 24 then deforms quite simply in the vacuum of the annular space formed between the elements 2 and 4, according to substantially the same amplitude as that which would have been obtained in the presence of deformable sectors 32, still due to the main function of mechanical fuse of these sectors.
- the spacing means 30 of the container 1 allow a punctual deformation of the lateral internal wall 24, the amplitude of this deformation being limited by the initial thickness of the space present between the lateral internal wall 24 and the main structure. 4, so that this wall 24 does not directly strike the structure 4 of the container 1.
- the thickness of the annular space may for example be fixed so that the maximum deformation of the lateral internal wall 24, caused by a punch 46 under stress conditions similar to those encountered during regulatory tests, is compatible with this thickness.
- the spacing means 30 are also advantageously designed so as to generally resist mechanical stresses due to the significant inertia of the main structure 4 generated during falls of 9 meters, more particularly during horizontal falls, usually not causing deformation of the side face 6 of the package 2.
- FIGS. 6 and 7 there is shown partially a container 100 for the storage / transport of non-irradiated radioactive material such as fresh nuclear fuel assemblies (not shown), according to a second preferred embodiment of the present invention.
- the annular space provided between the main structure 4 and the lateral internal wall 24 is no longer partially or completely filled by the deformable sectors 32 of the first embodiment, but remains an empty space 150 avoiding any direct contact between the lateral internal wall 24 and the main structure 4, so as to allow a punctual deformation of this lateral internal wall 24 of the package 2 during a punching test.
- the spacing means 130 are provided on the fixed bottom 8 or on the cover 10 of the package 2, or preferably on both. These spacing means 130 thus make it possible to center the main structure 4 on the main longitudinal axis 19 of the container 100, so as to obtain an empty annular space 150 of substantially constant thickness.
- the spacing means 130 comprise for example a plurality of centering means 152, provided on the fixed bottom 8 and on the cover 10 and directed towards the interior of the container 100 (only the means centering 152 integral with the cover 10 being shown).
- Each centering means 152 is arranged along an axis identical to that of a housing 26 of the main structure 4, so as to be able to penetrate this same housing 26.
- the centering means 152 placed on the cover 10 and the bottom 8 of the packaging 2 are able to laterally support the main structure 4, in order to maintain it with respect to the lateral internal wall 24 of the container 100.
- any other spacing means 130 can be envisaged between a share the main structure 4 and secondly the fixed bottom 8 and / or the cover 10 of the package 2, without departing from the scope of the invention.
- the lateral internal wall 24 of the container 100 then simply deforms in the void of the annular space 150 formed between the elements 2 and 4, according to substantially the same amplitude as that which would have been obtained in the presence of spacing means acting as a mechanical fuse, interposed between the internal lateral wall 24 and the main structure 4.
- spacing means acting as a mechanical fuse interposed between the internal lateral wall 24 and the main structure 4.
