Abstract

A system for the vibration-damping and tectonically safe underground storage of substances, esp. of a radioactive material, uses a container of high stiffness and rounded shape which embedded in a soil of lower stiffness. The stiffness differential of the two media causes any possible line of break to beflected. Dynamic shocks are absorbed by a thixotropic buoyancy mass, filled between the two shells of the container. Earthquakes and other tectonic disturbances can thus not jeopardise the safe underground storage of hazardous substances. Even in case of cracks of the outer shell, the thixotropic filling seals them and prevents any escape.

Description

Anordnung zur schwingungsdämpfenden und tektonischArrangement for vibration dampening and tectonic

sicheren unterirdischen Lagerung von Stoffen jeglicher Art, insbesondere auch radioaktivem Material Die Erfindung betrifft eine Anordnung zur schwingungsdämpfenden und tektonisch sicheren unterirdischen Lagerung von Stoffen jeglicher Art, insbesondere auch radioaktivem Material.safe underground storage of substances of any kind, in particular also radioactive material The invention relates to an arrangement for vibration-damping and tectonically safe underground storage of substances of any kind, especially radioactive material.

Die bisher bekanntgewordenen Lagerungsmethoden haben auf die Probleme der Tektonik und der relativen Blockverschiebungen im Boden kaum Bedacht genommen. Das Problem der unterirdischen, schwingungsgedämpften Lagerung wurde bisher im wesentlichen durch mechanische Vorrichtungen zu lösen versucht. The previously known storage methods have problems the tectonics and the relative block displacements in the soil were hardly taken into account. The problem of the subterranean, vibration-damped storage has hitherto essentially been tried to solve by mechanical devices.

Es bestand daher die Aufgabe, eine Anordnung zu schaffen, die eine tektonisch sichere unterirdische Lagerung von gefährlichen Stoffen, insbesondere auch radioaktivem Material ermöglicht. Erreicht wird dies durch die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale. It was therefore the task to create an arrangement that one tectonically safe underground storage of dangerous substances, in particular also allows radioactive material. This is achieved through the in the license plate of claim 1 specified features.

Die gekennzeichnete Lagerungsanordnung erfüllt auf neue Weise folgende Aufgaben: 1) Die runde Form der Außenschale und der gezielt ausgesuchte Gründungsboden mit einer niedrigen Steifeziffer von E = 2000 bis 2 etwa 30 000 kN/m2, also z.B. Tone und Schluffe bis halbfeste Konsistenz, bewirken, daß eine mögliche tektonische Bruchlinie, die durch die Lage des Behälters führen würde, auf die wesentlich härtere Schale des Behälters abgeleitet und somit die bauliche Substanz des Komplexes unbeschädigt bleibt. The marked storage arrangement fulfills the following in a new way Tasks: 1) The round shape of the outer shell and the carefully selected foundation soil with a low stiffness of E = 2000 to 2 about 30,000 kN / m2, e.g. Clays and silts to semi-solid consistency, cause a possible tectonic Break line, which would lead through the position of the container, to the much harder one The shell of the container is diverted and the structural substance of the complex is thus undamaged remain.

2) Die Stoßwirkung eines tektonischen Vorganges wird durch die Tixotropie der Zwischenmasse gedämpft, wobei sich auch das um den Auftrieb verminderte Gewicht des Behälters begünstigend auswirkt.2) The impact of a tectonic process is caused by the tixotropy the intermediate mass is damped, with the weight reduced by the buoyancy of the container has a beneficial effect.

3) Als zusätzliche Sicherheit für den Fall einer Zerstörung der äußeren Schale wiederholt sich der Ableitungseffekt der Bruchlinie an der Außenwand der inneren Schale, verstärkt durch die Tixotropie der Zwischenmasse.3) As additional security in the event that the exterior is destroyed The derivation effect of the fault line is repeated on the outer wall of the shell inner shell, reinforced by the tixotropy of the intermediate mass.

4) Die Filterkuchenbildung der tixotropen Zwischenmasse bewirkt eine zusätzliche Abdichtung etwaiger Risse der äußeren oder inneren Schale.4) The filter cake formation of the thixotropic intermediate mass causes a additional sealing of any cracks in the outer or inner shell.

Eine besonders sichere Lagerung wird erreicht, wenn die Steifigkeit des Behälters annähernd mindestens tausend mal größer als die Steifigkeit des umgebenden Bodens ist. A particularly safe storage is achieved if the rigidity of the container approximately at least a thousand times greater than the rigidity of the surrounding Bottom is.

Nachstehend ist die Erfindung an Hand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher beschrieben. Dabei zeigt die Fig. 1 einen Längsschnitt und die Fig. 2 einen Querschnitt durch eine erfindungsgemäße Anordnung. The invention is illustrated below with reference to one in the drawings Embodiment described in more detail. 1 shows a longitudinal section and FIG. 2 shows a cross section through an arrangement according to the invention.

Gemäß den Zeichnungen ist der Mantel der äußeren Schale 1 zylindrisch ausgebildet und besteht aus Schlitzwänden variierbarer Stärke. Der Boden 2 und die Decke 3 besteht jeweils aus einer Ortbetonplatte. Die innere Schale 4 kann aus Materialien verschiedener Art je nach Erfordernis des zu lagernden Gutes hergestellt werden. Ihre Form soll jedoch kugelähnlich gehalten sein. Der Raum zwischen den beiden Schalen wird mit einer tixotropen Masse 5, z.B. Bentonit, gefüllt. Seine Konsistenz hängt vom Gewicht der inneren Scha]e (Behälter) und ihres Inhalts ab. Das um den Auftrieb verminderte Gewicht des Behälters wird durch schwingungsdämpfende Lager 6 getragen. Der Behälter kann durch eine verschließbare Luke 7 von oben her zugänglich gemacht werden. Eingebettet ist der doppelschalige Behälter in einen Boden niederer Steifigkeit, insbesondere einem tonigen oder schluffigen Boden. According to the drawings, the shell of the outer shell 1 is cylindrical formed and consists of slotted walls of variable thickness. The floor 2 and the Ceiling 3 consists of an in-situ concrete slab. The inner shell 4 can be made of materials of various types depending on the requirements of the goods to be stored. However, their shape should be kept spherical. The space between the two shells is filled with a thixotropic mass 5, e.g. bentonite. Its consistency depends on the weight of the inner bowl (container) and its contents. That about the buoyancy Reduced weight of the container is supported by vibration damping bearings 6. The container can be made accessible from above through a closable hatch 7 will. The double-shelled container is embedded in a base of low rigidity, especially a clayey or silty soil.

Zusammenfassend kann gesagt werden, daß die beschriebene Lagerungsmethode ihren Vorteil aus dem mathematisch erfaßbaren Zusammenwirken der bodenphysikalischen Eigenschaften des Gründungsbodens, der Tixotropie der Zwischenmasse und dem bautechnischen Konzept von Form und Stärke der Schale zieht. In summary, it can be said that the storage method described their advantage from the mathematically detectable interaction of the soil physics Properties of the foundation soil, the tixotropy of the intermediate mass and the structural engineering Concept of the shape and strength of the peel draws.
