Definitions
- the invention relates to an arrangement for transporting in particular UF 6 comprising an inner container with outgoing from this and their faces superior skirts and the inner container receiving from a first and a second shell composite outer container, wherein the shells in enclosing the inner container preferably in a Level lie on one another, in or parallel to the longitudinal axis of the inner container, and wherein from one of the end faces of the inner container a valve emanates, which is surrounded by the outer container and spaced therefrom and the outside is covered by at least one shock-absorbing element.
- Uranium hexafluoride (UF 6 ) is transported in cylindrical steel containers. These containers are specified in ISO 7195 "Packaging of Uranium Hexafluoride (UF 6 ) for Transport” or in ANSI N14.1 "Uranium Hexafluoride - Packaging for Transport”. During transport, these containers must comply with the requirements of the IAEA's Regulations for the Safe Transport of Radioactive Material TS-RI and the requirements of the international and national regulations derived therefrom. "Steel containers for uranium hexafluoride with an enrichment of more than 1% by weight of uranium. 235 in uranium are surrounded during transport by a protective container forming an outer container, which should comply with the above requirements.
- uranium hexafluoride For containers containing uranium hexafluoride with an enrichment of more than 1% but not more than 5% by weight of uranium-235 in uranium, the following requirements shall apply, including the normal and accident conditions of carriage defined in TS-RI : The steel container, so the inner container, the protective container, so the outer container and the content consisting of uranium hexafluoride form the package within the meaning of the regulations.
- the required protective function can be provided by an outer container, which can also be designated as a protective packaging, which completely surrounds the steel container filled with uranium hexafluoride, ie the inner container, wherein the outer container, ie the first and second shells respectively forming a half shell, each have a z.
- B. made of sheet metal sheath having a shock absorption and thermal insulation z. B. enclose foam.
- a first embodiment is dispensed with a positive positioning of the particular valve to be protected. Due to the frontal arrangement of the valve thus a large-scale reinforcement of the end faces of the protective container is required because a faulty loading or rotation of the container during transport can not be safely excluded. If the reinforcement is made only locally, there is a risk that the valve is positioned outside the reinforced area and thus not sufficiently protected. In this embodiment, both end faces must be reinforced, since an assignment of the valve side of the steel container to a certain end face of the protective container is not given. If the end faces are insufficiently reinforced, there is a risk of physical contact between the valve and another component of the packaging, since the distance between the valve and the inner wall of the protective container is only a few mm.
- the steel container is positioned by a laterally mounted in the protective container bracket via a hole in the steel container welded to the apron.
- the protective container has an internal recess and external reinforcement.
- the steel container so inner container, based solely on the apron in the protective container, the outer container from.
- Calculations by means of the finite element method show that in the first embodiment, a buckling of the skirt with subsequent damage to the valve can not be excluded.
- the areas adjacent to the skirt are reinforced and support them, but the mass and cost of the second embodiment are substantially higher than in the first.
- DE-T-699 02 774 relates to an enclosure for receiving a cylinder containing uranium hexafluoride.
- the cylinder has a tendency in the forehead areas zen.
- a valve extends in the longitudinal direction of the cylinder from an end face, which is surrounded by one of the aprons.
- Subject of DE-A-28 54 358 is a transport container for radioactive materials, which can be closed by a lid, which is penetrated by a drainage channel. The channel goes into a valve, which is surrounded by a hood-like cover seal.
- a container for transporting uranium hexafluoride has in its end faces valves which are surrounded by dome-shaped caps which extend within aprons extending in extension of the peripheral wall of the container (WO-A-2004/072985).
- a transport arrangement according to EP-A-0 777 238 comprises an inner and an outer container.
- the inner container has circumferential aprons in its frontal areas. From one end face is a valve disposed within one of the skirts and spaced from the container.
- a receptacle for receiving uranium hexafluoride has circumferential skirts in its end areas in order to protect valves which extend from the end faces.
- the present invention is based on the object, an arrangement of the type mentioned in such a way that a defined positioning of the outgoing from the inner container valve and thus the inner container to the surrounding outer container, so protective container is ensured. Also, a sufficient protection of the valve should be ensured before the loads defined in the aforementioned regulations. Furthermore, in comparison with the known embodiments, a reduction in costs while at the same time saving weight should be provided without changes in the dimensions.
- the object is essentially achieved in that the shock-absorbing protective element extends from one of the shells as the first shell of the outer container or from the valve-side skirt of the inner container movable, pivotable and / or displaceable, that the protective element with proper positioning of the inner container to the Outer container covers the valve and that the protective element is covered on the outside of at least one of the shells when the outer container is closed.
- the invention provides that the movable and pivotable element or protective element has a valve-remote as articulation-side first portion and a valve covering the second portion and consists of this.
- the first section on the valve-side extending end face can be supported.
- the second portion can be supported on the annular surface surrounding the end face apron.
- at least one support element protruding from the second section exits on the valve-side end face.
- the movable as well as pivotable and / or displaceable shock-absorbing element - also called device - ensures that the inner container to the first shell of the outer container, from which the pivotable element basically goes out, must be properly aligned to pivot the element so to be able to ensure that the valve is covered to the required extent. Should the required positioning not be given, then the shock absorbing element is not movable in a scope such as pivoting, that the second shell is placed on the first shell for enclosing the container and connectable to this.
- the protective container ie outer container, equipped with a movable as folding protective device (element), which is filled with shock-absorbing materials and reinforced in the region of the valve, positioned by possibly positive locking the valve in this device and by large-scale support of the steel container the load on the skirt is reduced so much that buckling and thus damage to the valve can be ruled out.
- the protective device can be connected to the first shell via a hinge, i. H. be connected to the lower part of the protective container to be moved after loading of the lower part with the loaded with uranium hexafluoride or other material, especially radioactive material steel container in the required proper position as folded.
- the upper part can only be placed if the valve is properly positioned in the device.
- the device is fixed by the upper part of the protective container.
- the valve is loaded opposite of the element in the protective container, since in this positioning the element is not moved to the extent required as folded and the top of the protective container can be placed.
- the protective container which contains the element according to the invention as an integral part, can only be loaded in the intended orientation of the steel container and positioning of the valve.
- the existing in the movable element shock absorption relieves the skirt, which could buckle due to the loads, since the protective element protrudes either over the apron or on the outside extends at least in a plane which is spanned by the outer edge of the skirt. At present, this option does not offer any of the embodiments used.
- the use of lightweight shock-absorbing materials in the moveable element results in a substantial reduction in the mass of the protective container compared to the presently used embodiment.
- the shock absorbing element so the protection device is pivotable about an axis which is parallel or approximately parallel to the plane in which the shells lie on each other. In this plane preferably extends the longitudinal axis of the inner container.
- the shell covering the shock-absorbing element that is to say the second or upper shell, has a smaller frontal thickness than the first or lower shell.
- the invention also provides, in a further development, that the first section of the pivotable element has, on the articulation side, a particularly stepped cutout in which the first shell engages in a form-fitting manner when the outer container is closed.
- the protective element should have a jacket of steel such as stainless steel, which may have a wall thickness in the range between 10 mm and 20 mm. From the jacket then shock-absorbing material is added, which is at least one material from the group phenolic resin, polyurethane foam, wood such as balsa wood.
- shock-absorbing material is added, which is at least one material from the group phenolic resin, polyurethane foam, wood such as balsa wood.
- the shock absorbing element which is also referred to as a device, according to the invention is arranged to be movable to the inner containers.
- Movable includes a pivoting and / or moving a.
