Definitions

  • the invention relates to a transport and / or storage container with at least one recorded in a receiving space radioactive element with a container bottom, a container shell and adjacent to the receiving space container lid, wherein in the vertical Aufstellzusatz the container a space with an axial distance f between the radioactive Element and the container lid is present and wherein container inside the container bottom at least one spring element is provided, wherein the spring element in the vertical installation state of the container by the weight of the radioactive element under bias can be set.
  • Radioactive elements here means in particular spent or fresh fuel or HAW glass kokillen (HAW: high active waste).
  • Transport and / or storage containers of the type described above are available in various embodiments.
  • an axial distance or an axial clearance is usually realized between the recorded radioactive elements, for example between the recorded fuel assemblies and the container lid.
  • the accordingly set vertical height of the receiving space of the container initially takes into account the fact that in the container components or radioactive elements with different dimensions must be accommodated.
  • manufacturing tolerances must be taken into account with respect to the container components and with respect to the incorporated components.
  • the fact must be taken into account that a relative thermal expansion of recorded components and container components can take place and a change in length of the components received in the container due to radioactive irradiation.
  • a small, axial space between radioactive elements and container lid is required even if the container lid is functionally reliable, for example remotely operated, must be placed under water.
  • Most of these known containers have proven themselves in terms of strength or stability.
  • the mechanical resistance with regard to certain exceptional situations can be improved or in need of improvement.
  • Such an exceptional situation is in particular the free fall of a container which then impinges with the container lid-side front end or the container lid-side end face on a rigid base. In the free fall phase there is a gap between the recorded radioactive elements and the container lid. In this way, it comes as it were to a delayed impact of the elements and both the lid system and the recorded elements are relatively heavily loaded. It is understood that such a high load is undesirable for safety reasons.
  • DE 202 09 845 U discloses a container system for transporting and storing highly radioactive materials having an outer container in which an inner container is received enclosed by a central container.
  • the outer container has in its interior on the inner surface and on the lid and the bottom plate inwardly directed spring elements which are biased by a biasing means with the proviso that the central container is received in the outer container free-floating.
  • the mounting of this container system is very expensive especially under water and remote control.
  • the invention addresses the technical problem of specifying a transport and / or storage container of the type mentioned, in which the disadvantages described above are avoided and is characterized in free fall with lid-side impact by strength or stability and thus safety.
  • the invention teaches a transport and / or storage container, which is characterized in that the Vorspannweg V of the spring element is greater than the distance f of the radioactive element to the container lid in the vertical installation state of the container and that the radioactive element Container bottom side has a recess for receiving at least a portion of the spring element.
  • radioactive elements are accommodated in the receiving space of the container.
  • the radioactive elements are preferably spent or fresh fuel elements or HAW glass kokillen.
  • a basket for receiving the radioactive elements in the receiving space is available.
  • at least one spring element can also be arranged between the support basket and the container bottom.
  • the term radioactive element in the context of the invention in principle also means a carrying basket, a carrying element or a casing for a radioactive element or for a plurality of radioactive elements.
  • transport and / or storage container comprises a lid system with several lids, for example a primary lid and a secondary lid, then container lid means the inner lid immediately adjacent to the receiving space for the radioactive elements. - It is within the scope of the invention that between
  • Container bottom and radioactive element is provided at least one spring element.
  • the spring element When the spring element is set according to the invention under bias, its length is reduced. The spring element is so compressed as it were under the weight of the radioactive element or the radioactive elements. Vorspannweg the spring element means in the invention, the distance or the way by which the spring element is compressed under the weight of the radioactive element in comparison to the relaxed state of the spring element.
  • the spring element is in the vertical installation state of the container by a vertical installation state of the container in particular means that the container bottom of the container rests on a substrate and the container lid is oriented on the upper side of the container.
  • the spring element is a helical spring.
  • the coil spring is suitably made of steel.
  • Spring element in the context of the invention basically means any element which is compressible under the weight of a radioactive element or can be placed under bias, and which shows an elastic resilience when relieved.
  • a radioactive element on the container bottom side has a recess for receiving at least part of a spring element.
  • a transport and / or storage container according to the invention is usually a plurality of radioactive elements.
  • each radioactive element has a container bottom side recess for receiving a spring element. If the radioactive elements are fuel elements, then the container bottom-side recess is located in the base of a fuel assembly. Conveniently, this recess is cylindrical.
  • the container bottom side recess is preferably formed as a dome-shaped recess.
  • a spring element in the vertical installation state of the container is taken over its length completely in the container bottom side recess.
  • Length of the spring element here means the extension in the longitudinal direction of the container parallel to the container walls.
  • a complete recording of the prestressed spring element or the residual length of the prestressed spring element takes place in the container bottom side recess.
  • the invention is based on the finding that an inventively arranged transport and / or storage container a free fall from relatively large heights with impact of the lid-side end face on a rigid Underlay without significant damage or damage can survive.
  • the invention is based in particular on the finding that with the construction of the container according to the invention, stronger loads on the cover system during impact can be effectively and reliably avoided. It should be emphasized that the container according to the invention can be realized with relatively simple and inexpensive measures.
  • the figures show a transport and / or storage container according to the invention with a receiving space 1 for radioactive elements 2.
  • the container has a container bottom 3, a container casing 4 and a container lid 5 adjoining the receiving space 1 for the radioactive elements 2.
  • a Spring element 6 is provided, which is preferably designed and in the embodiment as a helical spring.
  • Fig. 1 shows the spring element 6 in the unloaded state.
  • the radioactive element 2 is here introduced straight into the receiving space 1 of the container. In the unloaded state, the spring element 6 has a length 1.
  • Fig. 2 shows the state in which the spring element 6 is biased by the weight of the radioactive element 2.
  • the spring element 6 has been compressed here in comparison to its original length 1 in the unloaded state by the Vorspannweg v.
  • the generated Vorspannweg v of the spring element 6 is greater than the distance f of the radioactive element 2 to the container lid 5 in the vertical installation state of the container.
  • the radioactive element 2 container bottom side has a recess 7 for receiving the spring element 6.
  • the recess 7 is provided here in the foot of the radioactive element 2.
  • the spring element 6 is preferably and in the embodiment in the vertical installation state of the container or in its prestressed state over its length completely received in the container bottom side recess 7 of the radioactive element 2.
  • Fig. 3 shows the container in reverse orientation during free fall with subsequent impact on the container lid 5.
  • the biased spring element 6 presses the radioactive element 2 against the container lid 5.
  • No distance between radioactive element 2 and container lid 5 build in the free fall phase, which would lead to a delayed impact and thus to a greater load on the container lid 5. Due to the measures according to the invention, the container lid 5 is effectively protected or protected during the impact.
