Abstract

Ein Behälter zum Lagern von radioaktiven Stoffen mit einem durch eine umlaufende Schweißnaht (6) am Behälteraußenmantel (3) dicht befestigten Verschlußdeckel (5) besitzt einen am Behältereraußenmantel (3) befestigten, die Schweißnaht (6) mit einem inneren Flansch (8) mit Abstand (9) überdeckenden Ringkörper (7). Führungsnuten (11) am Ringkörper (7) für das Einrasten von Transportelementen lassen ihn gleichzeitig als Transportring dienen.A container for storing radioactive substances with a sealing cover (5) which is tightly attached to the outer casing (3) by a circumferential weld (6) has a welded seam (6) with an inner flange (8) at a distance to the outer casing (3) (9) covering ring body (7).

Description

Die Erfindung betrifft einen Behälter zum Lagern von radioaktiven Stoffen nach dem Oberbegriff des Patentanspxuches 1, wie er beispielsweise der DE-OS 31 50 663 zu entnehmen ist.The invention relates to a container for storing radioactive substances according to the preamble of patent claim 1, as can be seen, for example, from DE-OS 31 50 663.

Behälter dieser Art müssen mechanisch stabil, korrosionsfest und dicht verschlossen sein. Das dichte Verschließen erfolgt durch einen in die stirnseitige Aufnahmeöffnung eingefügten mit der Behälterwand verschweißten Verschlußdeckel. Diese Abdichtung in Form einer umlaufenden Schweißnaht muß den Abschluß von der Biosphäre über einen praktisch unbegrenzten Zeitraum gewährleisten. An sie werden deshalb äußerst hohe Anforderungen gestellt. Dabei geht es nicht nur um die Qualität der Verschweißung, sondern auch um deren Beständigkeit gegen unbeabsichtigte Gewalteinwirkungen.Containers of this type must be mechanically stable, corrosion-resistant and tightly sealed. The tight closure is achieved by a closure lid which is inserted into the front receiving opening and welded to the container wall. This seal in the form of a circumferential weld seam must ensure the closure of the biosphere over a practically unlimited period. Therefore, extremely high demands are placed on them. It is not just about the quality of the welding, but also about its resistance to unintended violence.

Die Abdichtung, d.h. die umlaufende Schweißnaht zwischen dem Verschlußdeckel und dem Behältermantel, soll gegen mechanische Beschädigungen gesichert werden.The seal, i.e. the all-round weld seam between the sealing lid and the container jacket should be secured against mechanical damage.

Gemäß der Erfindung besitzt der Behälter das im Kennzeichen des Patentanspruches 1 genannte Merkmal.According to the invention, the container has the feature mentioned in the characterizing part of claim 1.

Der Ringkörper greift nur am Behälteraußenmantel an. Er überdeckt die Schweißnaht und sichert sie so gegen Gewalteinwirkungen, wie sie beispielsweise beim Transport auftreten können.The ring body only engages the outer shell of the container. It covers the weld seam and secures it against the effects of violence, such as can occur during transport.

Um auf jeden Fall ein Übertragen von Stößen durch ein Umkippen oder gar Abstürzen des Behälters auf die Schweißnaht zu vermeiden, empfiehlt es sich, den Ringkörper nur unterhalb der Schweißnaht am Behälteraußenmantel zu befestigen und ihn mit Abstand den stirnseitigen Bereich des Behälteraußenmantels, die Schweißnaht sowie einen Teil des Verschlußdeckels überdecken zu lassen. Starke Stößel die speziell-auf die Kanten auftreffen können, werden somit von dem etwas verformbaren Ringkörper aufgefangen und direkt auf den Behälteraußenmantel übertragen. Der Abstand garantiert ein berührungsloses Abschirmen der Schweißnaht gegen äußere Gewalteinwirkungen.In order to avoid the transmission of impacts due to the container tipping over or even falling onto the weld seam, it is advisable to attach the ring body only below the weld seam to the outer shell of the container and to place it at a distance from the front area of the outer shell of the container, the weld seam and one Cover part of the cover. Strong plungers that can hit the edges are caught by the somewhat deformable ring body and transferred directly to the outer shell of the container. The distance guarantees contactless shielding of the weld seam against external violence.

Die Wirkung des Ringkörpers als Stoßdämpfer kann noch zusätzlich durch Vorsprünge oder eine umlaufende Erhöhung an dessen Oberseite verbessert werden. Evtl. auftretende Stöße werden von diesen Vorsprüngen über den etwas verformbaren Bereich des Ringkörpers auf den Behälteraußenmantel übertragen. Ein besonderer Vorzug des Ringkörpers besteht darin, daß er als Transportring verwandt werden kann. Zu diesem Zweck besitzt er Führungen zum Einrasten von Transportelementen. Somit werden nicht nur StöBe, sondern auch Zugkräfte während des Transportes von der Schweißnaht fern gehalten und nur vom Behälteraußenmantel übernommen.The effect of the ring body as a shock absorber can be further improved by protrusions or a circumferential increase on its top. Possibly. Shocks that occur are transmitted from these projections to the outer shell of the container via the somewhat deformable area of the ring body. A particular advantage of the ring body is that it can be used as a transport ring. For this purpose, it has guides for snapping transport elements into place. This means that not only shocks, but also tensile forces are kept away from the weld seam during transport and only taken over by the outer shell of the container.

Die beigefügte Zeichnung zeigt in einer einzigen Figur einen Längs-schnitt durch einen schematisch dargestellten Transportbehälter.The attached drawing shows in a single figure a longitudinal section through a schematically represented transport container.

'Der Behälter besteht aus einem dickwandigen Grundkörper 1 , der unter Zwischenfügung einer Zwischenschicht 2 in einen Außenmantel 3 aus geeignetem, hochwertigem Gußwerkstoff eingebettet ist. Ein Deckel 4 des Grundkörpers 1 ist durch einen weiteren Verschlußdeckel 5 abgedeckt, wobei der Verschlußdeckel 5 mit dem Außenmantel 3 durch eine umlaufende Schweißnaht 6 absolut dicht verbunden ist.'The container consists of a thick-walled base body 1, which is embedded with an intermediate layer 2 in an outer jacket 3 made of a suitable, high-quality cast material. A cover 4 of the base body 1 is covered by a further cover 5, wherein the closure cap 5 is absolutely tightly connected to the outer jacket 3 by a circumferential weld 6.

Am Außenmantel 3 ist ein Ringkörper 7 mit einem nach innen weisenden Flansch 8 befestigt, und zwar im dargestellten Fall durch eine Schraubverbindung. Dieser Ringkörper 7 bzw. dessen Flansch 8 überdeckt den stirnseitigen Bereich 3' des Außenmantels 3 die Schweißnaht 6 sowie einen Teil des Verschlußdeckels 5 mit Abstand 9. Hierdurch wird eine Wirkung des Ringkörpers 7 als Stoßdämpfer erzielt, welche durch Vorsprünge 10 am Flansch 8 des Ringkörpers 7 noch verstärkt wird.,On the outer casing 3, an annular body 7 is fastened with an inwardly facing flange 8, in the case shown by a screw connection. This ring body 7 or its flange 8 covers the front area 3 'of the outer casing 3, the weld 6 and part of the sealing cap 5 at a distance 9. This has the effect of the ring body 7 as a shock absorber, which is provided by projections 10 on the flange 8 of the ring body 7 is reinforced.,

Führungen 11 am Flansch 8 des Ringkörpers 7 dienen zum Einrasten von Transportbolzen einer Transportmaschine. Der Ringkörper 7 besitzt somit die Funktion eines Schutz-und Transportringes.Guides 11 on the flange 8 of the ring body 7 are used for locking transport bolts of a transport machine. The ring body 7 thus has the function of a protective and transport ring.

Im dargestellten Fall ist nur an einem stirnseitigen Ende des Behälters ein Ringkörper angeordnet. Es ist selbstverständlich möglich, an beiden Stirnseiten Ringkörper anzubringen, um die dämpfende Wirkung derselben allseitig zu nutzen.In the case shown, an annular body is arranged only at one end of the container. It is of course possible to attach ring bodies to both end faces in order to utilize the damping effect thereof on all sides.
