Definitions

  • the invention relates to a device for storing radioactive material with an inner container receiving the material and an outer container surrounding the inner container made of a ceramic material.
  • the outer container has at least one insertion opening to be closed with a lid only after the inner container has been introduced.
  • shock loads are applied to the bottom or the lid by the inner container those that lead to stress peaks that promote the brittle fracture of the ceramic outer container. Even if the material is not destroyed by the sudden acceleration forces, the connection between the closure parts of the outer container and the base body of the outer container can be broken.
  • the acceleration forces are thus transmitted to the inner container on a large area of the outer container evenly or without a notch effect.
  • the engagement which is distributed over a large area, can be achieved, on the one hand, via one or a few larger engagement surfaces, or, on the other hand, via a large number of smaller individual engagement surfaces evenly distributed over the inner wall of the outer container, as long as the total engagement surface required for securely holding the inner container is present.
  • the individual smaller engagement surfaces must not be so small that notch effects occur can.
  • the engagement is a sole frictional engagement, a frictional engagement supported by adhesive bonding or a sole adhesive bonding.
  • the outer wall of the inner container is in direct engagement with the inner wall of the outer container or there is at least one engagement element with the inner container in a non-positive or positive connection, the outer wall of which engages with the inner wall of the outer container.
  • a large engagement surface in particular a friction engagement surface, is achieved from the outset. If only one or a small number of engagement elements are used, these bear larger engagement surfaces on the inner wall of the outer container in order to achieve a uniform introduction of the forces and a good heat transfer from the inner container to the outer container. If a plurality of engagement elements are used, these lie with their smaller individual engagement surfaces in a uniform distribution, forming a sufficient total engagement surface on a large area of the inner wall of the outer container.
  • a weld, soldering, gluing is understood in addition to a frictional connection.
  • the outer wall of the inner container or the outer wall or the engaging surfaces of the engaging element or the whole engaging element are preferably made of a metallic material which ensures good heat transfer from the inner container to the outer container.
  • the size of the frictional engagement is also determined by the choice of material.
  • the outer wall of the inner container or the frictional engagement element or the frictional engagement elements can be prestressed are.
  • a frictional engagement element as the engagement element, this preferably consists of a slotted sleeve part and an abutment connected to the inner container.
  • the sleeve part can be pretensioned in the circumferential direction, so that its outer surface lies against the outer container with a defined force.
  • the abutment can be formed by a separate component or by welding, soldering, gluing or the like.
  • the wall of the inner container is preferably provided with at least one bead or the like which extends in the longitudinal direction and opens towards the outer surface of the inner container.
  • the outer wall of the inner container then lies against the inner wall of the outer container and the pre-tension that is set can be predetermined by designing the bead.
  • the inner cross-section of the outer container and the outer cross-section of the inner container have a cylindrical cross-section, cylinder-like being understood to mean all bodies not delimited by a polygonal lateral surface.
  • This means that the application is in particular not limited to circular cylindrical cross sections.
  • deviations from the cylindrical shape can occur, which can be compensated for using separate frictional engagement elements.
  • the frictional engagement elements can be formed individually and can be connected individually to the inner containers or the friction closing elements are integrally formed with one another at least in groups. Furthermore, if a plurality of frictional engagement elements are used, these are preferably tongue-shaped.
  • a frictional engagement element assembly with at least two sleeves inserted into one another can be provided to increase the frictional forces, the slots of the two sleeve parts being offset in the circumferential direction.
  • the sleeve part and the abutment can be formed in one piece with one another or separately from one another.
  • the inner wall of the outer container like a truncated cone in the area of the frictional engagement form and adapt the outer wall of the inner container or the frictional engagement element to this configuration.
  • the frustoconical design of the surfaces in frictional engagement when the sleeve is moved in the event of a load in the axial direction, the normal forces and thus the frictional forces are progressively increased in that the prestressing force is increased in accordance with the truncated cone angle by compressing the sleeve or the inner container.
  • the large end surface of the truncated cone is adjacent to one end of the outer container or the center of the outer container.
  • a frictional engagement along conical surfaces is also possible if no separate frictional engagement elements are used, but instead the outer wall of the inner container together with the inner wall of the outer container are designed accordingly.
  • the inner container can be held in the inner container of the outer container solely by frictional engagement over a large area. be; but it is also possible that the frictional connection is supported by an adhesive that does not hinder the thermal behavior of the system. Ceramic adhesives are particularly suitable for this, as will be explained further below.
  • the outer container 1 made of a ceramic material consists of a cylindrical jacket 2, a bottom 3 and a lid 4, the bottom 3 and lid 4 being connected in a suitable manner to the free end faces of the jacket 2.
  • An inner container 5 which consists of a cylindrical jacket 6, a base 7 and a cover 8, is introduced into the outer container.
  • the inner container is made of metal, so that the base and lid are connected to one another along weld seams 9 (it is also possible for the cover 6 and base 7 to form a deep-drawn unit).
  • the inner container 5 is filled with heat-releasing radioactive material in a manner not shown.
  • a manipulation pin 10 is attached to the lid 8 for handling the inner container.
  • the inner container 5 is held in the outer container 1 by two frictional engagement elements 11 which are intended to derive the dynamic forces acting on the inner container 5 into the ceramic wall.
  • Each frictional engagement element 11 consists of a sleeve part 12 provided with a longitudinal slot 12a and a sleeve end ring 13 provided with a slot 13a, which can be connected to the sleeve part by means of a connection technique shown in broken lines in FIG. 1.
  • Suitable connection technology e.g. a bolt connection.
  • the sleeve parts 12 encompass the inner container when the device is assembled with a predetermined play S.
  • the bottom 9 of the inner container is supported by a spring ring 14 on the sleeve end ring of the lower friction element, while the cover 8 is supported by a spring ring 14 on the sleeve end ring 13 of the upper friction element, wherein the manipulation pin 1o engages in the free space of the sleeve end ring 13.
  • the sleeve part 12 can be reduced in diameter with the aid of a tool, not shown, by reducing the width of the slot 12a to such an extent that it can be inserted into the cylindrical jacket 12.
  • the dimensions are chosen so that after the tool has been removed from the sleeve part 12, it rests with a defined radial prestress on the inner wall of the outer container 1. Then the inner container 5 is inserted (it is assumed that the lower frictional engagement element has already been installed) until it rests on the lower spring ring 14. The upper spring ring 14 is then introduced and the sleeve end ring 13 is connected to the free end face of the sleeve part 12, the slots 12a and 13a being aligned.
  • the sleeve end rings 13 are held at a distance from the bottom 3 or at a distance from the cover 4 to be put on.
  • the inner container When the device is accelerated in the axial direction of the container, the inner container is held in such a way that the bottom 3 and lid 4 of the outer container are not exposed to shock loads, since the sleeve end rings 13 serving as abutments absorb the axial forces and introduce them into the sleeve (of course, the connection between Sleeve part 12 and sleeve end ring 13 must be designed so that this introduction takes place safely).
  • the forces are diverted into the ceramic material via the large-area frictional engagement between the outer surface of the sleeve parts 12 and the inner wall of the cylindrical jacket 2, without this being exposed to shock loads or notch effects.
  • the arrangement is designed such that, after the clamping tool has been removed, the sleeve parts apply the desired force to the cylindrical inner surface, but at the same time the radial slot 12a is not closed, but still has a predetermined slot width.
  • the sleeve part 12 is provided with an insertion truncated cone 12b.
  • the jacket has a straight cylindrical outer surface 16a, while the inner surface 17 consists of a central straight cylindrical section 17a and two frustoconical surface sections 17b adjoining the outside.
  • the bottom and lid of the outer container 15 have a hood character. The design of the base and lid is not essential for the present invention.

  • the inner surface 2ob of the sleeve part 2o is of straight cylindrical design, while the outer surface 2oc is also designed as a truncated cone, adapting to the frustum angle of the frustoconical surface section 17b. In the assembled state, the inner surface 2ob has play S from the outer surface of the inner container 5.
  • a locking opening 21a is provided in such a way that after the frictional engagement element 19 has been placed on the inner container and after a corresponding relative rotation of the frictional engagement element with respect to the inner container, an axial separation between the two components connected in such a positive manner is no longer possible. If one disregards the fact that the surface section 17a can be relatively long, the configuration of the two outer surfaces 2oc can be compared with the diabolo toy, in which a rotating body with a corresponding truncated cone configuration is used. In the case of an axial displacement forced by axial acceleration forces, for example from above in FIG.
  • the frictional engagement between the outer surface 2oc of the upper frictional engagement element 19 and the associated surface section 17b of the outer container 15 is progressively increased, since the normal force acting on the surface section 17b is compressed by the Sleeve part 2o is increased according to the cone angle of the frustoconical surfaces in engagement.
  • the extent of the compression of the sleeve part is preferably limited by or by the predetermined slot width of the slot 2oa previous installation of the inner surface 2ob with reduction of the game S on the outer surface of the inner container 5. Which measure is effective depends on the design of the slot width and its size in comparison to the game S.

  • the frusto-conical sleeve part 25b has a uniform wall thickness, so that the play S between the cylindrical outer surface of the inner container 22 and the frustoconical inner surface of the sleeve part 25b increases from the outside inwards.
  • the outer surface of the sleeve part 26b abuts the inner surface of the frustoconical outer sleeve 26, which is also of a substantially uniform wall thickness.
  • the frictional forces can be compared Use of only a single slotted sleeve can be increased. If the frictional forces between the two sleeves 25 and 26 are sufficient, the outer surface of the outer sleeve could also be fixed to the surface 27a by gluing or welding. In the sense of the present application, the outer sleeve 26 would then have to be regarded as the inner wall of the outer container with respect to the frictional engagement.
  • the inner container does not necessarily have to be a stepped one, but it is easier to construct from two cylindrical sections.
  • the truncated cone surface 27a widens from the outside inwards and then merges into an oppositely acting surface 27b, which in turn merges into a straight cylindrical surface (not shown).
