JP6145456B2 - Container for transporting and / or storing radioactive material - Google Patents

Description

  The present invention relates to the field of packages for transporting and / or storing radioactive material, preferably in the form of spent nuclear fuel assemblies.

  Traditionally, storage devices, also referred to as storage “baskets” or “rack”, are used to ensure the transport and / or storage of radioactive materials. Typically, these storage devices having a cylindrical shape and a substantially circular or polygonal cross-section can receive radioactive material. The storage device is intended to form a container for transporting and / or storing radioactive material contained in the package cavity and completely enclosed therein.

  The aforementioned cavities are generally defined by a side body extending along the longitudinal axis of the package, as well as a bottom surface and a package cover disposed at both ends of the body in the direction of the longitudinal axis. The side body has an inner wall and an outer wall, which generally have the shape of two concentric metal collars and form an annular space between the walls, in which a heat conductor as well as radiation protection means are housed. Forms a barrier against neutrons emitted by radioactive material contained in the cavity. This neutron shielding is conventionally made using so-called “resin concrete” material.

  Thermal conductors allow the heat released by the radioactive material to be conducted out of the container, causing degradation of these materials, alteration of the mechanical properties of the package components, or even abnormal pressure rise in the cavity. Avoid any risk of overheating you get.

  Thermal conductors have been intensively developed and have resulted in various results. One of the most commonly used outcomes is to fin the inter-wall space so that each end of the fin contacts the two collars to create a thermal bridge. These fins extending longitudinally in the direction of the longitudinal axis of the package thus allow heat to be transferred from the inner collar to the outer collar. On the other hand, in this result, radiation protection blocks are conventionally inserted between the fins in the inter-wall space of the side body.

  More specifically, each thermal conductor supports at least one penetrating member for penetrating the inter-wall space and one of the inner wall and the outer wall of the package side body at one of the ends of the penetrating member. And a first support connection member for connection. In general, the other end of the conductor is provided with a second support connection member for supporting and connecting the other of the two walls. Each support connection member, on the other hand, has a plurality of attachment points to its associated wall of the package side body, and these attachment points are usually the clearing hole of the mounting screw to the side wall. It has a form.

  The heat conductor and side wall are generally formed of materials having different coefficients of thermal expansion. Indeed, the conductor is generally made of copper, aluminum or their alloys, and the inner and outer walls are made of steel. Accordingly, fixtures provided at the attachment points must take into account the differential thermal expansion phenomenon between these elements without creating mechanical stresses that can alter their mechanical connection. In addition, the fixture must be able to avoid any deformation of the support member that could harm the normal contact of that member with the wall to which it is attached, and thus provide heat transfer between the wall and the conductor. . For this purpose, each attachment point is generally provided with an oval hole that passes through the support connection member, and a screw housed in the relevant wall of the side body passes through this hole. Thanks to this oval hole, a relative displacement is allowed between the support member and its associated wall that allows the differential expansion stress to be compensated by performing a loose tightening of the screw.

  However, loose screw tightening is a heat transfer limiting factor. Therefore, there is a need to optimize current solutions with the goal of improving the heat transfer function while allowing differential thermal expansion of existing elements.

  One object of the present invention is to at least partially overcome the above-mentioned drawbacks associated with prior art embodiments.

  To this end, one object of the present invention is to transport and / or store radioactive materials including side bodies with inner and outer walls defining an inter-wall space in which at least one heat conductor is disposed. The inner wall defines a containment cavity for radioactive material, the thermal conductor includes at least one penetrating member for penetrating the space between the walls, and the penetrating member. A first support connection member (referred to as a first wall) for supporting and connecting one of the inner wall and the outer wall of the package side body is provided at one end of the mold member, and the first support connection member Has a plurality of first attachment points on the first wall of the package side body, the first attachment points being spaced apart from each other in the longitudinal direction of the heat conductor.

  According to the present invention, the first support connection members are partitioned in the longitudinal direction to define first sections separated from each other by a first groove disposed between the first attachment points. Each first groove is cut into the penetrating member that defines the closed end of the first groove.

  With the proposed solution, the first sections can be expanded towards their ends without stress on either side of their attachment points by consuming the width of the grooves that form the clearance between the sections.

  Furthermore, the proposed solution no longer requires the presence of an oblong hole as in the prior art, and in particular a tight attachment of the attachment points to the respective walls to achieve better heat transfer. Enable.

  Advantageously, the present invention is thus less susceptible to reciprocal effects resulting from tightening the screws at the attachment points, as was the case before.

  Preferably, the ratio of the width of each first groove to the length in the longitudinal direction of either of the two first sections arranged on both sides of the groove is 0.005 to 0.1.

  Preferably, each first groove cuts into the penetrating member over a distance that is 40 to 90% of the full width of the penetrating member in the direction of the groove.

  Preferably, each first groove extends substantially perpendicular to the longitudinal direction of the heat conductor. However, these grooves can be tilted differently without departing from the scope of the present invention.

  Preferably, each of the first support connection member and the through-type member has a substantially flat shape parallel to the longitudinal direction. Both these elements preferentially intersect to form a V-shape with an internal angle of 90 to 150 °, for example.

  Preferably, a second support (optional connection) for supporting and optionally connecting the other of the inner wall and the outer wall of the package side body is called a second wall on the other end of the penetrating member. ) Members are provided.

  According to an envisaged embodiment, the second support member is arranged in succession with the penetrating member enclosed here between two sectors of the second wall, here generally the outer wall of the body.

  In this embodiment, the second support members are sectioned in the longitudinal direction and separated from each other by second grooves cut into the penetrating members that define the closed ends of the second grooves. Define the second section. Thereby, the behavior of the heat conductor can be improved with respect to the mechanical stresses generated during thermal expansion, especially when the first groove only has a small length at the trough.

  In other words, these second grooves provide greater flexibility to the support member secured between the sectors of the second wall, thus improving the overall flexibility of the heat conductor.

  According to another embodiment, the second support member is supported on and optionally connected to the surface of the second wall that defines the inter-wall space. In this case, the conductor has a preferentially substantially S or Z-shaped cross section, and the convex angle between the penetrating member and each of the two support members is preferably 90 to 150 °. is there.

  Here, the second support members are preferentially segmented in the longitudinal direction and are separated from each other by the second grooves cut into the through-type members that define the closed ends of the second grooves. The second section is defined. Alternatively, the second support member may be continuous, i.e., without a groove, without departing from the scope of the present invention.

  The solution by the second groove is such that the second support member has a plurality of second attachment points on the second wall of the package side body, and the second attachment points have a second section. Of particular interest when placed between the separating second grooves. In that case, the benefits obtained from these second grooves can be compared with those of the first groove as described above.

  In other cases where the second groove is considered to be created despite the absence of attachment points on the second support member, this also again causes the thermal conductor to behave in particular, with the first groove being a penetrating member. It can be improved with respect to the mechanical stresses that occur during thermal expansion if it only has a small length. In other words, these second grooves impart increased overall flexibility to the thermal conductor.

Regardless of the solution chosen, whether or not the second support member is provided with a second attachment point, the conductor may include the following elements.
The penetrating member (30);
-Said first support connection member;
-Said second support member;
Another through-type member integral with one of the first and second support members, wherein the first and second grooves of the first and second support members are cut into the first and second support members; And said other penetrating member in which each closed end of the second groove is defined;
-Other first or second support member integral with the other penetrating member;
Thereby, the above-mentioned element as a whole defines a generally Ω-shape, and the other first or second support member is sectioned in the longitudinal direction and separated from each other by the first or second segment. Each first or second groove is cut into the other penetrating member that defines the closed end of the first or second groove.

  Thus, this embodiment can include either two first support members and one second support member, or two second support members and one first support member, These support members are connected in both cases by both penetrating members. Furthermore, at least one second support member can be provided, or a second attachment point need not be provided, depending on the required needs.

  Furthermore, with this particular design in which each first support member can be attached to the inner wall or outer wall of the package side body, the grooves that carry the respective penetrating portions of both penetrating members each have a support member that connects them. It penetrates Ω shape (capital omega) by penetrating. Thus, these grooves are generally U-shaped and help to obtain great flexibility of the heat conductor.

Preferably, the conductor has a generally corrugated shape, with the radially outer peak and the radially inner peak following each other alternating, the generally corrugated shape is
An outer pattern oriented radially outwardly between two radially inner peaks, in addition to from the first or second support member, two penetrating members extending on both sides of the support member; Each outer pattern made using,
An inner pattern oriented radially inward between two radially outer peaks, in addition to from the first or second support member, two penetrating members extending on both sides of the support member; Each internal pattern made using,
Each groove penetrates not only the support member, but also a part of each of both penetrating members of its associated pattern.

  This configuration is related to the achievement as a single piece of several adjacent Ω-type heat conductors as described above. Thus, each conductor extends as a single piece in a large angular sector of the inner wall annular space, for example 45 ° to 180 °.

  In the above-described embodiment, the first groove and the second groove preferably follow each other alternately in the longitudinal direction. However, other configurations in the distribution of the first and second grooves may be envisaged without departing from the scope of the present invention.

  Preferably, the first support connection member is attached to the first wall at the first attachment point by a screw element or welding. The same applies to the second attachment point if they are provided on the second support connection member.

  Finally, the first wall of the package side body is preferentially an inner wall, but may alternatively be an outer wall.

  Further benefits and features of the present invention will become apparent upon reading the following detailed non-limiting description.

  This description is made with reference to the following accompanying drawings.

  Referring initially to FIG. 1, a container 1 is preferably presented for transporting and / or storing spent nuclear fuel assemblies.

  The container 1 generally comprises a package 2 for the purposes of the present invention, in which a storage device 4, also called a storage basket, is arranged. The device 4 is arranged to be placed in the receiving cavity 6 of the package 2, and as shown schematically in FIG. 1, the longitudinal axis 8 of this package can be seen, which is identical to the vertical axis of the receiving device and the receiving cavity. it can.

  Throughout the description, the term “longitudinal” should be understood as parallel to the longitudinal axis 8 and the longitudinal direction of the package.

  The container 1 forming the housing for receiving the nuclear fuel assembly and its device 4 are now shown in the horizontal / lateral position normally taken during transport of the assembly to load / unload the fuel assembly. Different from the vertical position.

  In general, the package 2 has a bottom surface (not shown) on which the device 4 is intended to be placed in a vertical position, a cover (not shown) disposed at the other longitudinal end of the package, and a longitudinal axis 8 about it. A side body 10 extending substantially along the longitudinal direction of the container 1 is provided.

  It is this side body 10 that defines the receiving cavity 6, and more particularly the inner wall 20 that uses a side inner surface 12 having a substantially cylindrical shape and circular cross-section and having the same axis as the axis 8. is there.

  With further reference to FIG. 1, the design of the side body 10 is presented in more detail, which primarily includes two concentric metal walls / collars that together form an inter-wall annular space 14 about the longitudinal axis 8 of the package. Have In fact, this is an inner wall / collar 20 about the axis 8 and an outer wall / collar 22 also about the axis 8.

  The inter-wall space 14 is filled with radiation protection means 18 that is essentially designed to form a barrier against neutrons emitted by the fuel assemblies contained in the containment device 4. Thus, these elements are accommodated between the inner wall 20 and the outer wall 22 whose inner surface corresponds to the side inner surface 12 of the cavity 6. The radiation protection means 18 is made of a material known per se, such as a polymer matrix composite, more precisely the matrix is for example a resin of the vinyl ester resin type, preferably a strongly hydrogenated resin. This neutron protective material is also known as “resin concrete”. On the other hand, additives intended to make the composite material self-extinguishing can be incorporated.

  The means 18 is preferably made as a prefabricated block distributed circumferentially in the annular space 14, separated by two by a heat conductor 16 in contact with the two walls 20, 22 respectively. These conductors 16 made of an alloy having good heat conduction properties in the form of aluminum or copper alloy are specific to the present invention and will now be described in detail with respect to FIGS.

  Initially referring to FIG. 2, a thermal conductor 16 according to a preferred embodiment is presented, which preferably extends over the entire length of the space 14 in the direction of the axis 8 or alternatively Divided into parts by direction.

  In cross section, the conductor has a generally stretched S or Z shape, the two convex angles that it defines are each 90 to 150 °.

  The conductor first has a penetrating member 30 for penetrating the space between the walls, which member 30 has a sufficiently large width to connect the walls 20 and 22 of the package side body. Presents a planar shape. In FIG. 2, the 1st support connection member 32 for supporting and connecting the wall is provided in the end located in the inner wall side which is a low end.

  Similarly, a second support connection member 34 for supporting and connecting the other wall (that is, the outer wall) of the side body is provided on the opposite side of the penetrating member 30.

  The three members 30, 32, 34 are each preferably in the form of three plane plates, all in parallel with the direction of the axis 8 and together define both convex angles as described above. Made as a piece.

  Each individual support member 32, 34 is intended to contact its associated wall, preferably by its entire surface. In this embodiment, only member 32 is intended to be screwed to the inner wall of the package body using a first mounting point 36, each taking the form of a clearing hole in the mounting screw. The hole 36 is here preferentially circular and has a diameter slightly larger than the diameter of the mounting screw. They are probably spaced apart from each other in the direction of the axis 8 even though several attachment points may cooperate by being laterally spaced, i.e. they are separated from each other in a direction perpendicular to the direction of the axis 8. Is done. Preferably, each of these groups contains only two attachment points.

  One of the features of the present invention is the segmentation of the first support member 32 in the longitudinal direction, and the first segments 32a separated from each other by a first groove 40 disposed between the first attachment points. Is defined. Indeed, each segment 32a preferably has a single attachment point 36, or may have a single group of points in the above sense and centered about segment 32a.

  Each groove 40 defines an independent segment 32a that penetrates the entire support connection member 32 and is connected by a material ligament (ligament part) two by two with a penetration type member in which each groove 40 extends. In fact, each groove 40 has a first open end at the edge of the member 32 as well as a second opposite closed end disposed in the penetrating member 30.

  Each groove 40 thus has an L-shape arranged in a plane perpendicular to the axis 8. The ratio of the width to the length in the vertical direction of any one of the two first segments 32a arranged on both sides of the groove 40 is 0.005 to 0.1. In this regard, it should be noted that the width of the groove 40 is, for example, approximately 2 mm with a step of approximately 100-150 mm in the longitudinal direction.

  Furthermore, each groove 40 cuts into the penetration member 30 over a distance that is 40-90% of the full width of the penetration member in the direction of the groove, so the length of the remaining material ligament (ligament) is this penetration. This corresponds to 10 to 60% of the entire width of the mold member 30.

  In FIG. 3, a similar conductor is shown, and the first support connection member 32 is intended to be attached to the outer wall of the package side body. Accordingly, the second support member 34 is intended here simply to contact the inner wall.

  The embodiment shown in FIGS. 4 and 5 is derived from that of FIG. 2 and comprises a second support member 34 shaped similarly to the first member 32. In other words, the second support member 34 is segmented in the longitudinal direction to define second segments 34 a that are separated from each other by the second groove 42.

  Each groove 42 penetrates the entire support connection member 34 and defines an independent segment 34a that is connected by a material ligament (ligament part) two by two in the penetrating member 30 in which each groove 42 extends. Indeed, each groove 42 has a second opposite closed end disposed in the penetrating member 30 in addition to a first open end at the edge of the member 34.

  Again, each groove 40 is shaped in an L shape arranged in a plane orthogonal to the axis 8 and has dimensions and proportions similar to those described for the first groove 40.

  In this regard, the first and second grooves 40, 42 are preferably located in separate planes by being arranged alternately, but several first grooves between two adjacent second grooves 42. Note that 40 can be placed or vice versa.

  In both aspects presented in FIGS. 4-5 a, the first and second grooves 40, 42 cut into the penetrating member 30 deep enough to have overlapping areas 46 when viewed in the direction of the axis 8. It is out. Thus, the penetration type member 30 takes the shape of a substantially rectangular sine wave by the regular alternating of the 1st and 2nd groove | channels, and the regular clearance gap between the same thing.

  In FIG. 4, the second sectioning member 34 is only intended to be supported on its associated wall of the package side body, whereas in the embodiment of FIGS. 5 and 5a, this connection to the wall 22 is first. Provided by a second attachment point 48 similar to the one point 36. In fact, each segment 34a preferably has a single second attachment point 48 or has a single group of points in the above sense centered about segment 34a in the longitudinal direction.

  In FIG. 5a, the heat conductors 16 are continuous in the circumferential direction of the inter-wall space 14, and these conductors are preferably all identical and are separated by the presence of a prefabricated neutron protection block (not shown). It has been shown.

  Furthermore, it should be noted that in order to minimize stress concentrations at the closed ends of the grooves 40, 42, these ends have a rounded shape with a diameter greater than the width of the grooves.

  In FIG. 5 a, as in FIG. 8, which will be described later, a part of the mounting screw penetrating the point 36 is also described, and these screws are referred to by reference numeral 37.

  Referring now to FIGS. 6-7, two other preferred embodiments are shown. These are embodiments in which the second support connection member 34 is different from that shown in FIGS. 2 to 5, in which case the second support connection member 34 is continuous with the penetrating member 30, i.e. the member 30. Are intended to be enclosed between two successive corner sectors 22a of the outer wall 22. This arrangement is shown in FIG. 6 a, presenting two welded corner sectors 22 a and surrounding the edge of the second member 34.

  In the embodiment of FIG. 6, the first groove 40 may be substantially identical to that of the previous embodiment, or may be cut to a level where the opposite support member 34 itself is not segmented. However, the support member 34 is segmented in another embodiment of FIG. 7 and defines second segments 34a spaced from each other by a substantially straight second groove 42. In fact, each groove 42 here penetrates the entire support connection member 34 and defines an independent segment 34a which is simply connected two by a material ligament (ligament part) at the penetration type member 30 in which each groove 42 is cut. To do. In fact, each groove 42 has a second opposite closed end disposed in the penetrating member 30 in addition to a first end open at the edge of the member 34. Again, the first and second grooves 40, 42 are preferably arranged in separate planes by being arranged in an alternating manner, but again there are several pieces between two adjacent second grooves 42. There is a possibility that the first groove 40 is arranged or vice versa.

  The first and second grooves 40, 42 cut into the penetrating member 30 sufficiently deep to have overlapping areas 46 when viewed in the direction of the axis 8.

  The preferred embodiment shown in FIG. 8 illustrates a heat conductor 16 that is generally Ω (capital omega). Here, they are two first support connection members 32 attached to the inner wall 20, a second support member 34 for contacting the outer wall of the package body, and two direct connections connecting the support members 32, 34. This is a penetrating member 30. Of course, the first member 32 could be attached to the outer wall and / or alternatively, two second members 34 and a single first member 32 could be provided.

  Each conductor 16 in FIG. 8 is then in the form of a conductor as presented in FIG. 4, and in addition to other through-type members 30, The other first member 32 at the end is added.

  Furthermore, the grooves 42 of the second member 34 are cut into the new penetrating member 30 so that each of these grooves 42 penetrates the second support member 34 connecting both penetrating members 30. By passing through each section of these members 30, it is generally U-shaped. The length of the groove 42 is preferably the same for each of both penetrating members 30.

  In addition, the added first member 32 is also segmented in the same manner as the other first members 32, again with segments separated by grooves 40 extending into the added penetrating member 30. Define. Here, the first grooves 40 of both members are such that they are located two by two on the same plane orthogonal to the axis 8. A longitudinal offset could alternatively be provided between these grooves 40 without departing from the scope of the present invention.

  Furthermore, even if a regular alternation between the grooves 40, 42 is possible, in this case two adjacent first grooves 40 in the direction of the axis 8 are two adjacent in the same direction. It is such that it is separated by the second groove 42.

  Finally, the last embodiment presented in FIG. 9 relates to the result as a single piece of several conductors 16 of the type shown in FIG. Although it comprises a first groove 40 of an adjacent conductor, it does not necessarily apply to this embodiment of FIG.

  In fact, in this last embodiment, where the conductor 16 has a generally wavy shape, there are alternating circumferential turns of the first and second support members 32, 34 that are connected two by two by the penetrating member 30. . Each conductor 16 extends as a single piece into the angular sector of the inter-wall annular space, for example 45 to 180 °. Furthermore, each support member 32, 34 is attached to its respective wall of the side body by means of attachment points 36, 48, even if the second member 34 is alternatively only in contact with the outer or inner wall of the side body. Attached.

  The corrugated shape defines a radially outer peak and a radially inner peak, which follow each other alternatingly and are formed by the second support member 34 and the first support member 32, respectively.

  In this way, it is possible to identify an outer pattern directed radially outward between the two radially inner peaks 32, 32, each outer pattern then being made from the second support member 34. In addition, the support member 34 is formed using two penetrating members 30 extending on both sides. These outer patterns are preferably generally inwardly U-shaped. In the same way, it is possible to identify the radially inwardly directed inner pattern between the two radially outer peaks 34, 34, each inner pattern being made from the first support member 32. In addition, it is made by using two penetration type members 30 extending on both sides of the support member 32. These outer patterns are preferably generally outwardly open U-shaped, meaning that adjacent outer and inner patterns share the same penetrating member 30 that forms a common branch of both U-shapes. .

  On the other hand, each first and second groove 40, 42 extends in the same manner as the groove 42 in the embodiment of FIG. That is, the groove penetrates a portion of each of both penetrating members 30 in their associated pattern, in addition to the support member connecting both these members 30.

  The grooves 40 and 42 are all shaped in a U shape in this way, and are alternately arranged in the longitudinal direction even if other distributions as shown by the respective heat conductors 16 in FIG. 8 are possible.

  Of course, various modifications may be made by those skilled in the art to the present invention described only as a non-limiting illustration.
