Description

Die Erfindung betrifft einen für den Transport und die Lagerung radioaktiver Stoffe geeigneten zylindrischen Behälter aus einer Stahlbetonwandung mit einer stirnseitigen, durch einen Stahlbeton­deckel verschließbaren Öffnung. Die Stahlbeton­wandung und der Stahlbetondeckel des Behälters sind jeweils innen- und außenseitig mit Stahlblechen verkleidet.The invention relates to a cylindrical container made of a reinforced concrete wall, suitable for the transport and storage of radioactive materials, with an opening on the front side which can be closed by a reinforced concrete cover. The reinforced concrete wall and the reinforced concrete cover of the container are clad on the inside and outside with steel sheets.

Ein derartiger Behälter ist aus der DE-OS 33 31 892 bekannt und hat die Vorzüge, daß durch den Stahlbeton die erforderliche Abschirmung der Strahlung gewährleistet ist, die von radioaktivem Material ausgeht, und daß durch die den Beton verkleidenden Stahlbleche die Stoßfestigkeit des Behälters erhöht ist. Weiterhin ist der bekannte Behälter aufgrund seiner verhältnismäßig niedrigen Herstellungskosten auch aus wirtschaftlicher Sicht geeignet, als Lagerbehälter für eine Zwischen- oder Endlagerung des in den Behälter eingebrachten radioaktiven Materials verwendet zu werden.Such a container is known from DE-OS 33 31 892 and has the advantages that the required shielding of the radiation is guaranteed by the reinforced concrete, which emanates from radioactive material, and that the steel sheet covering the concrete increases the impact resistance of the container . Furthermore, due to its relatively low manufacturing costs, the known container is also economically suitable to be used as a storage container for intermediate or final storage of the radioactive material introduced into the container.

Der Erfindung liegt die Aufgabe zugrunde, den bekannten Behälter zu verbessern und zu einem solchen zu gelangen, der sich bei gleichem Aufnahmevermögen durch kleinere Abmessungen und ein geringeres Gewicht gegenüber dem bekannten Behälter auszeichnet und bei dem insbesondere auch die Handhabung des Deckels vereinfacht ist.The invention has for its object to improve the known container and to achieve one that is characterized by smaller dimensions and a lower weight compared to the known container with the same capacity and in particular the handling of the lid is simplified.

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

Dadurch, daß die innenseitige Verkleidung der Stahl­betonwandung erfindungsgemäß aus einem Stahlblech besteht, das eine größere Wandstärke aufweist als das die außenseitige Verkleidung bildende Stahl­blech der Stahlbetonwandung, ergibt sich eine erhebliche Gewichtseinsparung gegenüber der bei dem bekannten Behälter gewählten Stahlblechanordnung, wobei die außenseitige Verkleidung der Stahlbeton­wandung aus einem Stahlblech besteht, das eine größere Wandstärke aufweist als das die innenseitige Verkleidung bildende Stahlblech der Stahlbetonwandung. Aufgrund der verhältnismäßig dicken Stahlbetonwandung ist die Fläche der außenseitigen Verkleidung wesentlich größer als die der innenseitigen Verkleidung, woraus sich in einfacher Weise die erhebliche Gewichtsverringerung bei der erfindungsgemäßen Anordnung erklärt.Characterized in that the inner lining of the reinforced concrete wall according to the invention consists of a steel sheet that has a greater wall thickness than the steel sheet forming the outer lining of the reinforced concrete wall, there is a considerable weight saving compared to the steel plate arrangement chosen in the known container, the outer lining of the reinforced concrete wall consists of a steel sheet which has a greater wall thickness than the steel sheet of the reinforced concrete wall forming the inside cladding. Due to the relatively thick reinforced concrete wall, the area of the outside cladding is considerably larger than that of the inside cladding, which explains the considerable weight reduction in the arrangement according to the invention in a simple manner.

Die gegenüber der außenseitigen Stahlblechver­kleidung in der Wandstärke größere innenseitige Stahlblechverkleidung schafft die Voraussetzung dafür, an dem die innenseitige Verkleidung bildenden Stahlblech Gewindeanker zu befestigen, die erfindungsgemäß auf der dem Stahlbeton zugewandten Seite der Verkleidung in gleichmäßiger Verteilung über den Umfang der Öffnung angeordnet sind.The wall sheet steel cladding, which is larger than the steel sheet cladding on the outside, creates the prerequisite for attaching threaded anchors to the steel sheet forming the inside cladding, which according to the invention are arranged on the side of the cladding facing the reinforced concrete in a uniform distribution over the circumference of the opening.

Die gemäß den weiteren erfindungsgemäßen Merkmalen in die Gewindeanker eindrehbaren und durch Bohrungen in eine Abdeckung einführbaren Schraubenbolzen erleichtern die Handhabung des Stahlbetondeckels insbesondere dadurch, daß die Abdeckung die außen­seitige Verkleidung des Stahlbetondeckels bildet und ringsum über diesen radial nach außen vorsteht, so daß der Betonkern des Stahlbetondeckels im Durch­messer wesentlich kleiner gehalten werden kann als seine die außenseitige Verkleidung bildende Abdeckung. Auch hierdurch ergibt sich eine Gewichtseinsparung, welche sich sowohl auf die erleichterte Handhabung des Deckels als auch auf die des Behälters insgesamt auswirkt.The screw bolts which can be screwed into the threaded anchors and inserted through holes in a cover according to the further features of the invention facilitate the handling of the reinforced concrete cover, in particular in that the cover forms the outside cladding of the reinforced concrete cover and protrudes radially outwards about it, so that the concrete core of the reinforced concrete cover can be kept much smaller in diameter than its cover forming the outside cladding. This also results in a weight saving, which affects both the easier handling of the lid and that of the container as a whole.

Nach einer Ausgestaltung der Erfindung ist der Außendurchmesser einer den Betonkern des Stahlbeton­deckels umgebenden verlorenen Schalung mindestens um den Außendurchmesser einer Hülse, die zur Führung der Schraubenbolzen dient und zwischen der innenseitigen Verkleidung und der außenseitigen Abdeckung des Deckels jeweils koaxial zu den Gewindeankern angeordnet ist, kleiner als der Teilkreis, auf dem die durch die Hülsen geführten Schraubenbolzen angeordnet sind.According to one embodiment of the invention, the outer diameter of a lost formwork surrounding the concrete core of the reinforced concrete cover is at least smaller than the outer diameter of a sleeve, which is used to guide the screw bolts and is arranged coaxially to the threaded anchors between the inner lining and the outer cover of the cover the pitch circle on which the bolts passed through the sleeves are arranged.

Durch diese erfindungsgemäße Ausgestaltung lassen sich die zur Führung der Schraubenbolzen dienenden Hülsen unbehindert durch den Stahlbetondeckel um den Außenumfang des Betonkerns koaxial zu den Bohrungen in den Gewindeankern plazieren, so daß die Schraubenbolzen über die Bohrungen der entsprechend winkelmäßig ausgerichteten Abdeckung des Stahlbetondeckels ordnungsgemäß eingedreht werden können, ohne daß es einer besonderen Ausrichtung des Stahlbetondeckels bedarf.With this configuration according to the invention, the sleeves used to guide the screw bolts can be placed unhindered by the reinforced concrete cover around the outer circumference of the concrete core coaxially with the bores in the threaded anchors, so that the screw bolts can be properly screwed in via the bores of the correspondingly angularly oriented cover of the reinforced concrete cover, without requiring a special alignment of the reinforced concrete cover.

Die zum sicheren Verschluß des Behälters erforderliche konzentrische Anordnung des Stahl­betondeckels läßt sich in einfacher Weise dadurch gewährleisten, daß nach einer weiteren Ausgestaltung der Erfindung eine die innenseitige Verkleidung des Deckels bildende Grundplatte des Stahlbetondeckels einen abgestuften Rand aufweist, der mit einer Rand­fläche auf einer Stirnseite des die innenseitige Verkleidung der Wandung bildenden Stahlblechs aufliegt.The necessary for the secure closure of the container concentric arrangement of the reinforced concrete cover can be ensured in a simple manner that, according to a further embodiment of the invention, a base plate of the reinforced concrete cover forming the inside lining of the cover has a stepped edge, which has an edge surface on an end face of the lining of the steel sheet forming the wall rests.

Liegt der Stahlbetondeckel in der vorbeschriebenen Weise auf der Stirnseite des die innenseitige Verkleidung der Wandung bildenden Stahlblechs auf, erübrigt sich eine weitere Justierung des Stahl­betondeckels, insbesondere auch eine Verdrehung in Relation zum Behälter, wenn nach einer weiteren Ausgestaltung der Erfindung die außenseitige Abdeckung des Deckels durch die in die Gewindeanker eindrehbaren Schraubenbolzen lösbar mit dem Stahlbetondeckel verbunden ist.If the reinforced concrete cover lies in the manner described above on the end face of the steel sheet forming the inside cladding of the wall, further adjustment of the reinforced concrete cover is unnecessary, in particular also twisting in relation to the container, if, according to a further embodiment of the invention, the outside cover of the cover is through the screw bolt which can be screwed into the threaded anchor is detachably connected to the reinforced concrete cover.

Durch diese erfindungsgemäße Ausgestaltung bedarf es zur ordnungsgemäßen Verbindung des Stahlbetondeckels mit dem Stahlbetonbehälter keiner winkelmäßigen Justierung des Deckels insgesamt, sondern lediglich einer solchen hinsichtlich der wesentlich leichter zu handhabenden äußeren Abdeckung des Stahlbetondeckels.This configuration according to the invention does not require an angular adjustment of the cover as a whole for the proper connection of the reinforced concrete cover to the reinforced concrete container, but only such an adjustment with regard to the outer cover of the reinforced concrete cover, which is much easier to handle.

Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß die Wandstärke des die äußere Verkleidung der Wandung bildenden Stahlblechs zur Wandstärke des die innere Verkleidung der Wandung bildenden Stahlblechs im Verhältnis von 1:3 bis 1:5 und vorzugsweise im Verhältnis von 1:4 steht.Finally, an embodiment of the invention provides that the wall thickness of the steel sheet forming the outer cladding of the wall to the wall thickness of the steel sheet forming the inner cladding of the wall is in a ratio of 1: 3 to 1: 5 and preferably in a ratio of 1: 4.

Mit dem erfindungsgemäßen Wandstärkenverhältnis der die Verkleidung bildenden Stahlbleche läßt sich unter Einhaltung aller sicherheitstechnischen Anforderungen, insbesondere auch hinsichtlich etwaiger Stoßbeanspruchungen beim Transport, das Gesamtgewicht des Behälters in Relation zu seinem Fassungsvermögen optimieren.With the wall thickness ratio of the steel sheets forming the cladding according to the invention, the total weight of the container can be optimized in relation to its capacity, while complying with all safety requirements, in particular also with regard to possible shock loads during transport.

Der für den Transport und die Lagerung radioaktiver Stoffe geeignete zylindrische Behälter besteht aus einer Stahlbetonwandung 1, für deren Herstellung Beton beispielsweise der Güteklasse B 25 K₃ mit einer Dichte 2,5 g/cm³ nach DIN 1045 verwendet wird.The cylindrical container suitable for the transport and storage of radioactive materials consists of a reinforced concrete wall 1, for the production of which concrete, for example, grade B 25 K₃ with a density of 2.5 g / cm³ according to DIN 1045 is used.

Die Stahlbetonwandung 1 ist in an sich bekannter Weise mit einer nicht dargestellten Stahlbewehrung armiert und außenseitig mit einem Stahlblech 2 und innenseitig mit einem Stahlblech 3 verkleidet.The reinforced concrete wall 1 is reinforced in a manner known per se with a steel reinforcement (not shown) and clad on the outside with a steel sheet 2 and on the inside with a steel sheet 3.

Bei einem zylindrischen Behälter, beispielsweise mit einem Außendurchmesser von 1.500 mm, einem Innen­durchmesser von 600 mm und einer Höhe von 2.900 mm, weist das die außenseitige Verkleidung bildende Stahlblech 2 eine Wandstärke von vorzugsweise 15 mm auf, wogegen die Wandstärke des die innenseitige Verkleidung bildenden Stahlblechs vorzugsweise 60 mm beträgt.In the case of a cylindrical container, for example with an outer diameter of 1,500 mm, an inner diameter of 600 mm and a height of 2,900 mm, the steel sheet 2 forming the outer lining has a wall thickness of preferably 15 mm, whereas the wall thickness of the steel sheet forming the inner lining is preferably 60 mm.

Auf der der Stahlbetonwandung 1 zugewandten Seite sind an dem die innenseitige Verkleidung der Stahl­betonwandung 1 bildenden Stahlblech 3 in gleich­mäßiger Verteilung über den Umfang einer stirn­seitigen Behälteröffnung 4 acht Gewindeanker 5 angeschweißt, die so angeordnet sind, daß ihre Gewindebohrungen 6 auf einem gemeinsamen Teilkreis liegen und parallel zur Behälterachse ausgerichtet sind.On the side facing the reinforced concrete wall 1, eight threaded anchors 5 are welded to the steel sheet 3 forming the inside cladding of the reinforced concrete wall 1 in a uniform distribution over the circumference of an end-side container opening 4, which are arranged so that their threaded holes 6 lie on a common pitch circle and parallel are aligned with the container axis.

Die Behälteröffnung 4 ist durch einen Stahlbeton­deckel 7 verschließbar, der aus einem Betonkern 8 be­steht, welcher von einer innenseitigen Verkleidung 9 und einer außenseitigen Abdeckung 10 aus Stahlblech­scheiben sowie von einer verlorenen Schalung 11 aus einem Stahlblechzylinder umschlossen ist.The container opening 4 can be closed by a reinforced concrete cover 7, which consists of a concrete core 8, which is enclosed by an inside cladding 9 and an outside cover 10 made of sheet steel disks and by a lost formwork 11 made of a sheet steel cylinder.

Die innenseitige Verkleidung 9 des Betonkerns 8 besteht aus einer Stahlblechscheibe, deren Außen­durchmesser größer ist als der Innendurchmesser des Behälters, wobei die Stahlblechscheibe einen so abgestuften Rand aufweist, daß sie nur mit einer Randfläche 12 auf der Stirnseite des die innenseitige Verkleidung bildenden Stahlblechs 2 aufliegt und im übrigen mit einem zylindrischen Teil nach Art eines Stopfens in die Behälteröffnung 4 eindringt.The inside cladding 9 of the concrete core 8 consists of a steel sheet disc, the outer diameter of which is larger than the inside diameter of the container, the steel sheet disc having a stepped edge such that it rests only with an edge surface 12 on the end face of the steel sheet 2 forming the inside cladding and otherwise penetrates into the container opening 4 with a cylindrical part in the manner of a stopper.

Die Abdeckung 10 des Betonkerns 8 besteht aus einer Stahlblechsscheibe, deren Außendurchmesser größer ist als der Außendurchmesser des die verlorene Schalung 11 bildenden Stahlblechzylinders. In dem somit über diesen vorstehenden Rand der Abdeckung 10 sind auf einem Teilkreis, der mit dem der Gewinde­bohrungen 5 übereinstimmt, in gleichmäßiger Verteilung über den Umfang der Abdeckung 10 acht Bohrungen 13 vorgesehen, durch die Schraubenbolzen 14 einführbar sind, die, in Hülsen 15 geführt, in die Gewindebohrungen 6 der Gewindeanker 5 eindrehbar sind.The cover 10 of the concrete core 8 consists of a sheet steel plate, the outside diameter of which is greater than the outside diameter of the sheet steel cylinder forming the lost formwork 11. In the thus over this projecting edge of the cover 10 eight holes 13 are provided on a pitch circle, which corresponds to that of the threaded holes 5, in a uniform distribution over the circumference of the cover 10, through which bolts 14 can be inserted, which are guided in sleeves 15 , can be screwed into the threaded holes 6 of the threaded anchor 5.

Um eine ebene Behälterstirnseite zu erhalten, sind nicht nur Köpfe 16 der Schraubenbolzen 14 in Aus­drehungen 17 der Bohrungen 13 vollständig versenkt, sondern ist auch der Stahlbetondeckel 7 in seiner Gesamtstärke, also einschließlich der Stärke der Abdeckung 10, so bemessen, daß die Oberseite der Abdeckung 10 bündig mit der Stirnseite der Stahlbetonwandung 1 abschließt.In order to obtain a flat front side of the container, not only heads 16 of the bolts 14 are completely sunk in bores 17 of the bores 13, but also the reinforced concrete cover 7 in its total thickness, that is to say including the thickness of the cover 10, such that the top of the cover 10 is flush with the end face of the reinforced concrete wall 1.
