Description

Die Erfindung bezieht sich auf eine aus einem zylindrischen Behälter bestehende Transport- und Lagervorrichtung für radioaktive Stoffe. Der Behälter ist mit einer geschlossenen Ummantelung aus Stahl, Beton oder Gußeisen hergestellt und weist stirnseitig eine durch einen Deckel verschließbare Öffnung auf. Eine Stirnfläche des Deckels ist gegen eine Stirnfläche der Ummantelung anpreßbar. Eine Randfläche des Deckels ist von einem aus der Ummantelung gebildeten Kragen abgedeckt. In gleich­mäßiger Verteilung über den Umfang des Kragens sind radiale Durchbrüche vorgesehen. Diesen liegen im Deckel angeordnete Aussparungen gegenüber.The invention relates to a transport and storage device for radioactive materials consisting of a cylindrical container. The container is made with a closed casing made of steel, concrete or cast iron and has an opening at the front that can be closed by a lid. An end face of the cover can be pressed against an end face of the casing. An edge surface of the cover is covered by a collar formed from the casing. Radial openings are provided in a uniform distribution over the circumference of the collar. These are opposite recesses arranged in the lid.

Eine derartige Transport- und Lagervorrichtung ist aus der DE-OS 33 31 892 bekannt und erfüllt trotz des verhältnismäßig kostengünstigen Aufbaues dennoch die an die Sicherheit von Transport- und Lagervorrichtungen für radioaktives Material zu stellenden hohen Anforderungen.Such a transport and storage device is known from DE-OS 33 31 892 and, despite the relatively inexpensive construction, nevertheless meets the high requirements to be placed on the safety of transport and storage devices for radioactive material.

Bei der bekannten Vorrichtung dienen zur sicheren Befestigung des Deckels auf der Behälteröffnung sowohl Schrauben, die den Deckel axial durchdringen und in in die Ummantelung des Behälters einge­bettete Gewindebuchsen eindrehbar sind, wie auch zylindrische Bolzen, welche den Kragen der Ummantelung des Behälters radial durchdringen und in entsprechende Aussparungen im Deckel eingreifen.In the known device serve for secure attachment of the lid on the container opening both screws that penetrate the lid axially and can be screwed into threaded jacks embedded in the casing of the container, as well as cylindrical bolts that penetrate the collar of the casing radially and into corresponding Engage recesses in the lid.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art hin­sichtlich ihrer Herstellung und Handhabung zu vereinfachen, ohne dadurch ihre hohe Funktions­sicherheit zu beeinträchtigen.The invention has for its object to simplify a device of the type described in terms of its manufacture and handling, without thereby affecting its high level of functional reliability.

Zur Lösung dieser Aufgabe wird von einer Vorrichtung der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, die erfindungsgemäß die im kennzeichnenden Teil des Patentanspruchs 1 genannten Merkmale aufweist.To achieve this object, a device of the generic type mentioned in the preamble of claim 1 is assumed, which according to the invention has the features mentioned in the characterizing part of patent claim 1.

Die erfindungsgemäß zum Deckelzentrum hin konisch verengten Aussparungen und die darin einpreßbaren, in den Durchbrüchen des Kragens geführten konischen Zapfen erfüllen sowohl die Funktion der Schrauben wie auch der zylindrischen Bolzen der bekannten Vorrichtung, so daß dazu anstelle zweier unter­schiedlich ausgebildeter Gruppen von Verbindungs­und Befestigungsmitteln lediglich eine erforderlich ist. Durch die erfindungsgemäße Konizität der Zapfen und der Aussparungen läßt sich der Deckel axial mit seiner Stirnfläche fest gegen eine Stirnfläche der Ummantelung pressen und gleichzeitig auch radial ausrichten und fixieren.The recesses which are conically narrowed towards the center of the cover and the pressable therein, which are guided in the openings of the collar, fulfill both the function of the screws and the cylindrical bolts of the known device, so that only one is required instead of two differently designed groups of connecting and fastening means is. Due to the conicity of the pins and the recesses according to the invention, the end face of the cover can be pressed axially firmly against an end face of the casing and at the same time also radially aligned and fixed.

Nach einer Ausgestaltung der Erfindung weist jeder Zapfen eine durchgehende konzentrische Bohrung für einen Gewindezapfen auf, der in eine Gewindebohrung im Boden der Aussparung eindrehbar ist.According to one embodiment of the invention, each pin has a continuous concentric bore for a threaded pin, which can be screwed into a threaded hole in the bottom of the recess.

Durch diese erfindungsgemäße Ausgestaltung ist eine dauerhafte Deckelverriegelung auch dann gewähr­leistet, wenn die Zapfen aufgrund einer verhältnis­mäßig starken Konizität dazu neigen sollten, sich selbsttätig radial nach außen aus den Aussparungen herauszubewegen.This configuration according to the invention ensures permanent cover locking even when the pins should tend to move radially outwards out of the recesses due to their relatively strong conicity.

Um eine außen weitgehend glattwandige Behälteraus­führungsform zu erhalten, sieht eine weitere Ausgestaltung der Erfindung vor, daß jeder Gewindebolzen aus einer mit ihrem Kopf im Zapfen versenkbaren Inbusschraube besteht.In order to obtain a largely smooth-walled container embodiment, a further embodiment of the invention provides that each threaded bolt consists of an Allen screw which can be countersunk in the pin with its head.

Jede Inbusschraube kann gegen ein unbeabsichtigtes Lösen nach einer weiteren Ausgestaltung der Erfindung mittels eines in der Bohrung des Zapfens einsetzbaren Seegeringes fixiert werden.Each Allen screw can be fixed against unintentional loosening according to a further embodiment of the invention by means of a circlip that can be inserted in the bore of the pin.

Schließlich können auch zur Sicherung des Deckelver­schlusses die Zapfen gemäß einer weiteren Ausge­staltung der Erfindung mit dem Kragen der Wandung verschweißt werden, was sich insbesondere dann empfiehlt, wenn der mit radioaktivem Material beladene Behälter als Zwischen- oder Endlager­vorrichtung dienen soll. In diesem Falle gewinnen die niedrigen Herstellungskosten der erfindungsge­mäßen Vorrichtung eine besonders hohe Bedeutung.Finally, according to a further embodiment of the invention, the pins can also be welded to the collar of the wall to secure the lid closure, which is particularly recommended if the container loaded with radioactive material is to serve as an intermediate or final storage device. In this case, the low manufacturing costs of the device according to the invention are particularly important.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung dargestellt. Es zeigen:

  • Fig. 1 einen abgebrochen dargestellten Teil des Behälters und des Deckels in einem vertikalen Schnitt;
  • Fig. 2 einen abgebrochen dargestellten Teil des Deckels in einem vertikalen Schnitt gemäß Fig. 1;
  • Fig. 3 einen der im Deckel eingelassenen, die Aussparungen bildenden Einsätze in gegenüber den Fig. 1 und 2 vergrößertem Maßstab.
In the drawing, an embodiment of the device according to the invention is shown. Show it:
  • Figure 1 shows a broken part of the container and the lid in a vertical section.
  • FIG. 2 shows a part of the cover shown broken off in a vertical section according to FIG. 1;
  • Fig. 3 one of the inserts in the lid, forming the recesses on an enlarged scale compared to Figs. 1 and 2.

Wie Fig. 1 erkennen läßt, besteht die Vorrichtung aus einem zylindrischen Behälter, dessen geschlossene Ummantelung 1 aus innen- und außenseitig mit Stahl­blechen 2 und 3 verkleidetem Stahl-Beton 4 hergestellt ist. Mit den Stahlblechen 2 und 3, die als verlorene Schalung für den Stahl-Beton 4 dienen, ist eine Abdeck­ringscheibe 5 verschweißt, die mit der oberen Stirn­fläche des die innenseitige Verkleidung bildenden Stahlblechs 2 bündig abschließt und vom die außen­seitige Verkleidung bildenden Stahlblech 3 so überragt wird, daß der überragende Teil des Stahlblechs 3 einen Kragen 6 bildet.As can be seen in FIG. 1, the device consists of a cylindrical container, the closed casing 1 of which is made of steel and concrete 4 clad with steel sheets 2 and 3 on the inside and outside. A cover washer 5 is welded to the steel sheets 2 and 3, which serve as lost formwork for the steel-concrete 4, which is flush with the upper end face of the steel sheet 2 forming the inside cladding and is thus towered over by the steel sheet 3 forming the outside cladding that the protruding part of the steel sheet 3 forms a collar 6.

Eine stirnseitige Öffnung des Behälters ist durch einen Deckel 7 verschließbar, der gleichfalls aus Stahl­Beton 8 hergestellt ist und auf seinen beiden Stirn­flächen mit Stahlblechscheiben 9 bzw. 10 sowie auf seiner Randfläche mit einem Stahlblechzylinder 11 ver­kleidet ist. Der Deckel 7 liegt mit einer Rand­fläche 12 der dem Behälterinnern zugewandten Stahlblechscheibe 9 auf der Abdeckringscheibe 5, während der Stahlblechzylinder 11 des Deckels 7 über seine volle Höhe von dem aus dem Stahlblech 3 gebildeten Kragen 6 seitlich abgedeckt wird. Auf der Unterseite der Stahlblechscheibe 9 ist eine Grund­platte 13 angeschweißt, die einen Durchmesser aufweist, der geringfügig größer ist als der Behälterinnendurch­messer und bis in eine Ausdrehung 14 im Randbereich des Stahlblechs 2 reicht. Auf der Oberseite der Stahlblech­scheibe 10 ist eine Abdeckplatte 15 angeschweißt, die einen Durchmesser aufweist, der geringfügig größer ist als der Innendurchmesser des Kragens 6 und mit dessen Stirnfläche verschweißbar ist.An end opening of the container can be closed by a lid 7, which is also made of steel-concrete 8 and is clad on both end faces with sheet steel disks 9 and 10 and on its edge face with a sheet steel cylinder 11. The cover 7 lies with an edge surface 12 of the sheet steel disc 9 facing the interior of the container on the cover ring disc 5, while the steel sheet cylinder 11 of the cover 7 is laterally covered over its full height by the collar 6 formed from the steel sheet 3. A base plate 13 is welded to the underside of the steel sheet disc 9, which has a diameter that is slightly larger than the inside diameter of the container and extends into a recess 14 in the edge region of the steel sheet 2. A cover plate 15 is welded onto the upper side of the sheet steel plate 10 and has a diameter which is slightly larger than the inside diameter of the collar 6 and can be welded to the end face thereof.

In gleichmäßiger Verteilung über den Umfang des Deckels 7 sind im Stahlblechzylinder 11 Öffnungen 16 vorgesehen. An jeder dieser Öffnungen 16 ist ein radial ausgerichteter, mit dem Stahlblechzylinder 11 verschweißter Einsatz 17 angeschlossen, der über einen radialen Steg 18 zusätzlich mit der Stahlblechscheibe 9 verschweißt und im Stahl-Beton 8 des Deckels 7 einge­gossen ist. Jeder Einsatz 17 weist eine zum Zentrum des Deckels 7 hin konisch verengte Aussparung 19 auf, deren Kegelwinkel im Ausführungsbeispiel etwa 11°, 25' beträgt. Koaxial zur Aussparung 19 ist im Boden 20 des Einsatzes 17 eine Gewindebohrung 21 vorgesehen.In a uniform distribution over the circumference of the cover 7 11 openings 16 are provided in the sheet steel cylinder. At each of these openings 16, a radially aligned insert 17 is welded to the sheet steel cylinder 11, which is additionally welded to the sheet steel disk 9 via a radial web 18 and is cast in the steel concrete 8 of the cover 7. Each insert 17 has a recess 19 which is conically narrowed towards the center of the cover 7, the cone angle of which in the exemplary embodiment is approximately 11 °, 25 '. A threaded bore 21 is provided in the bottom 20 of the insert 17 coaxially with the recess 19.

In einer der Anordnung der Einsätze 17 entsprechenden Anordnung sind mit den Öffnungen 16 im Stahlblech­zylinder 11 fluchtende Durchbrüche 22 im Kragen 6 vorgesehen. Durch jeden Durchbruch 22 läßt sich ein konischer Zapfen 23, dessen Kegelwinkel mit dem der Aussparungen 19 übereinstimmt, eintreiben, wobei eine entsprechende Wandstärke des Kragens 6 sicherstellt, daß der Zapfen 23 durch die Laibung der Durchbrüche 22 eine sichere Führung erhält.In an arrangement corresponding to the arrangement of the inserts 17, openings 22 in the collar 6 which are aligned with the openings 16 in the sheet steel cylinder 11 are provided. Through each opening 22, a conical pin 23, the cone angle of which coincides with that of the recesses 19, can be driven in, a corresponding wall thickness of the collar 6 ensuring that the pin 23 receives a reliable guidance through the reveal of the openings 22.

Beim Eintreiben der Zapfen 23 in die Aussparungen 19 wird der Deckel 7 mit der Randfläche 12 der Stahl­blechsscheibe 9 gegen die Abdeckringscheibe 5 der Ummantelung 1 gepreßt und fest darauf gehalten.When the pins 23 are driven into the recesses 19, the cover 7 with the edge surface 12 of the steel sheet disc 9 is pressed against the cover ring disc 5 of the casing 1 and held firmly thereon.

Um ein unbeabsichtigtes Herausgleiten der Zapfen 23 aus den Aussparungen 19 auszuschließen, ist jeder Zapfen 23 mit einer durchgehenden koaxialen Bohrung 24 versehen, worin ein Gewindebolzen 25 in Form einer Inbusschraube einführbar und in die Gewindebohrung 21 im Boden 20 des Einsatzes 17 eindrehbar ist. Zur Sicherung des mit seinem Kopf 26 versenkt in der Bohrung 24 eingelassenen Gewindebolzens 25 kann schließlich noch ein Seegerring in den erweiterten Teil der Bohrung 24 eingesetzt oder aber der Kopf 26 mit dem Kragen 6 verschweißt werden. Die gleiche Wirkung läßt sich mit einem die Öffnung der Bohrung 24 ganz oder teilweise abdeckenden, gleichfalls am Kragen 6 verschweißten Plättchen erzielen, wenn der Kopf 26 in der Endstellung des Zapfens 23 bündig mit der Außenseite des Kragens 6 abschließt.To prevent the pins 23 from inadvertently sliding out of the cutouts 19, each pin 23 is provided with a continuous coaxial bore 24, in which a threaded bolt 25 in the form of an Allen screw can be inserted and screwed into the threaded bore 21 in the base 20 of the insert 17. To secure the threaded bolt 25 sunk in the bore 24 with its head 26, a circlip can finally be inserted into the enlarged part of the bore 24 or the head 26 can be welded to the collar 6. The same effect can be achieved with a plate that completely or partially covers the opening of the bore 24 and is also welded to the collar 6 if the head 26 in the end position of the pin 23 is flush with the outside of the collar 6.
