Definitions

  • the invention relates to a device for storing radioactive material with an inner container holding the material and an outer container surrounding the inner container, in which the inner container is fixed therein by indirect engagement with the inner wall of the outer container.
  • a device for the storage of radioactive material in which the inner container is fixed axially with the help of holding-down devices in an outer container serving only for transport so that the inner container lid does not touch the lid of the outer container and in which the radial position of the inner container in the outer container is determined by a cross-sectional tapering of the interior of the outer container that runs toward the arc of the outer container.
  • the cross-sectional tapering of the interior of the outer container is brought about by correspondingly wedge-shaped profiles on the outer wall of the inner container and the inner wall of the outer container.
  • the wedge-shaped profiles preferably extend over the entire length of the inner container and fit into corresponding wedge-shaped profiles of the outer container, so that there is always metallic contact and thus metallic heat conduction between the inner and outer containers.
  • the hold-down devices engage in recesses in the inner wall of the outer container.
  • a device for storing radioactive material with a plurality of inner containers holding the material and an outer container surrounding the inner container made of ceramic material is known, in one embodiment of which the inner container designed as a glass cylinder in the outer container in a powder or granular material are embedded, which has a heat-insulating effect, while in the other embodiment, the inner containers are set in closed storage spaces.
  • the outer container is subjected to heat as a result of the heat of decay released in the inner container.
  • the outer container made of ceramic material has at least one insertion opening to be closed with a lid only after the inner container has been inserted.
  • shock-like loads are applied to the bottom or the lid by the inner container, which lead to a brittle fracture of the ceramic outer container, which promotes voltage peaks. 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.
  • This object is achieved in that when using ceramic material for the outer container with the inner container is at least one frictional engagement element in a non-positive and / or positive connection, the outer wall of which rests in large-area frictional engagement with the inner wall of the outer container.
  • Accelerating forces acting on the inner container are thus transmitted uniformly and without a notch effect over a large area of the outer container.
  • the large-area frictional engagement can be achieved on the one hand over one or a few larger engagement surfaces or on the other hand over 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 a secure holding of the inner container is given.
  • the individual smaller engagement surfaces must not be so small that notch effects can occur.
  • the frictional engagement is preferably a frictional engagement supported by adhesive.
  • the outer wall or the engagement surfaces of the frictional engagement element or the entire frictional engagement element are preferably made of a metallic material which ensures good heat transfer from the inner container to the outer container.
  • the choice of material also determines the size of the frictional connection.
  • the frictional engagement element or the frictional engagement elements can be prestressed.
  • the frictional engagement element 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.
  • Other preloadable frictional engagement elements are described in the description below.
  • the abutment can be formed by a separate component or by welding, soldering, gluing or the like.
  • 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 invention is in particular not limited to circular cylindrical cross sections.
  • the frictional engagement elements can be formed individually and can be formed individually with the inner containers and can be connected individually with the inner containers, or the frictional engagement elements are at least in one piece with one another.
  • these are preferably tongue-shaped.
  • a frictional engagement element assembly with at least two sleeves inserted into one another can be provided in their place to increase the frictional forces, the slots of the two sleeve parts being offset with respect to one another 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 and to adapt the outer wall of the frictional engagement element to this configuration.
  • the normal forces and thus the frictional forces are progressively increased when the sleeve is displaced in the event of a load in the axial direction in that the prestressing force is increased by compressing the sleeve in accordance with the truncated cone angle.
  • the large end surface of the truncated cone is adjacent to one end of the outer container or the center of the outer container.
  • the inner container can be be held in this frictional engagement of the frictional engagement element with the inner wall of the outer container; 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.
  • connection technology is suitable for.
  • 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 frictional engagement element, while the cover 8 is supported by a spring ring 14 on the sleeve end ring 13 of the upper frictional engagement element, the manipulation pin 10 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 2.
  • the dimensions are chosen such 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 frictional engagement elements 19 are formed in one piece and consist of a sleeve part 20 provided with a slot 20a and abutment sectors 21 which overlap the bottom or the cover 8 in the manner shown in FIGS. 3 and 4.
  • the inner surface 20b of the sleeve part 20 is of straight cylindrical design, while the outer surface 20c is also frustoconical, adapting to the frustum angle of the frustoconical surface section 17b. In the assembled state, the inner surface 20b has play S from the outer surface of the inner container 5.
  • a locking opening 21 is provided such 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 20c can be compared to the diabolo toy, in which a rotating body with a corresponding double-cone configuration is used. With an axial displacement forced by axial acceleration forces, e.g. B. from above in Fig.
  • the frictional engagement between the outer surface 20c of the upper frictional engagement element 19 and the associated surface section 17b of the outer container 15 is increased progressively, since the normal force acting on the surface section 17b by compressing the sleeve part 20 in accordance with the cone angle of the engaged located truncated cone surfaces is enlarged.
  • the degree of compression of the The sleeve part is preferably limited by the predetermined slot width of the slot 20a or by prior contact of the inner surface 20b with the clearance of the play 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 compared to the game S. .

  • the inner sleeve consists of a frusto-conical sleeve part 25b and a frustoconical abutment collar 25c formed integrally therewith, the inner surface of which rests on a corresponding bevel of the stepped portion 22a of the stepped inner container.
  • 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 25b bears on the inner surface of the frustoconical outer sleeve 26, which is also of substantially uniform wall thickness.
  • the frictional forces can be increased compared to the use of only a single slotted sleeve. 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).
