According to the method, the application of a subsequent reinforcement is provided, wherein at least partially steel shell elements are applied to the reinforced concrete shell as additional reinforcement, wherein at least some of the steel shell elements are welded to a liner and wherein at least some of the steel shell elements material and / or positive fit with the reinforced concrete shell be joined together a composite.
Description
Die Erfindung betrifft ein Verfahren zur nachträglichen Bewehrung eines Containments für Kernkraftwerke, welches eine monolithische Stahlbetonhülle umfasst. Beim Neubau von Kernkraftwerken wird das Reaktor-Containment von seiner Festigkeit so ausgelegt, dass es möglichen Flugzeugabstürzen standhält. Die in Stahlbetonbauweise erstellte Hülle kann hierzu mit innen- und außenliegenden Stahlblechstrukturen versehen werden. Hierbei wird dabei so vorgegangen, dass jeweils ein innerer und ein äußerer Stahlblechmantel aus stoßweise miteinander verschweißten Stahlblechpaneelen erstellt wird. Der Zwischenraum zwischen den Stahlblechmänteln/-linern wird mit einer Betonfüllung versehen, die Liner dienen dabei als verlorene Schalung für das Stahlbeton-Containment. Die Stahlblechelemente werden dabei üblicherweise mittels Kopfbolzen formschlüssig in dem Stahlbeton gesichert.The invention relates to a method for retrofitting a containment for nuclear power plants, which comprises a monolithic reinforced concrete shell. In the construction of new nuclear power plants, the reactor containment is designed so that it can withstand possible crashes. The shell constructed in reinforced concrete construction can be provided with internal and external sheet steel structures for this purpose. In this case, the procedure is such that in each case an inner and an outer sheet steel jacket is produced from intermittently welded steel sheet panels. The space between the steel sheet sheaths / liners is filled with concrete, the liners serve as permanent formwork for the reinforced concrete containment. The sheet steel elements are usually secured by means of a head bolt form fit in the reinforced concrete.
Eine Wandstruktur für ein Containment eines Kernkraftreaktors ist beispielsweise aus der
Bei nach dem Stand der Technik erstellten Neubauten von Kernkraftwerken ist grundsätzlich davon auszugehen, dass diese die Festigkeitsanforderungen insoweit erfüllen, dass diese hinreichend gegen Flugzeugabstürze gesichert sind.In new constructions of nuclear power plants constructed according to the state of the art, it is generally to be assumed that they meet the strength requirements to the extent that they are adequately secured against aircraft crashes.
Anders verhält es sich jedoch bei Anlagen, die bereits vor längerer Zeit geplant und errichtet wurden und einen potentiell geringeren Schutz gegen mögliche Flugzeugabstürze bieten.The situation is different, however, with installations that have been planned and built a long time ago and that offer potentially less protection against possible aircraft crashes.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren bereitzustellen, das die nachträgliche Ertüchtigung eines Containments für Kernkraftwerke ermöglicht, um auch bei Altanlagen einen wirksamen Schutz gegen mögliche Flugzeugabstürze zu erzielen.The invention is therefore based on the object to provide a method that allows the subsequent retrofitting of a containment for nuclear power plants to achieve effective protection against possible aircraft crashes even in old systems.
Erfindungsgemäß wird ein Verfahren zur nachträglichen Bewehrung eines Containments für Kernkraftwerke vorgeschlagen, wobei das Containment eine monolithische Stahlbetonhülle umfasst und das Verfahren vorsieht, dass auf die Stahlbetonhülle als zusätzliche Bewehrung zumindest bereichsweise Stahlmantelelemente aufgebracht werden, wobei zumindest einige der Stahlmantelelemente zu einem Liner verschweißt werden und wobei zumindest einige der Stahlmantelelemente stoff- und/oder formschlüssig mit der Stahlbetonhülle zu einem Verbund zusammengefügt werden.According to the invention, a method for retrofitting a containment for nuclear power plants is proposed, wherein the containment comprises a monolithic reinforced concrete casing and the method provides that at least partially steel shell elements are applied to the reinforced concrete shell as additional reinforcement, wherein at least some of the steel shell elements are welded into a liner and wherein at least some of the steel shell elements are material and / or form-fitting together with the reinforced concrete shell to form a composite.
Zweckmäßigerweise werden die Stahlmantelelemente und die Stahlbetonhülle so zusammengefügt, dass zwischen den einzelnen Lagen eine Verbundhaftung erzielt wird. Insbesondere bei einer aufprallbedingten Biegebeanspruchung eines solchen Sandwichverbundes wird der größte Anteil der auftretenden Zug- und Druckspannung im Bereich der Liner, d. h. bezogen auf die neutrale Faser außen vorliegen. In diesem Falle ist es zweckmäßig und wünschenswert, wenn eine Relativbewegung zwischen den Schichten der Sandwichstruktur, d. h. der Stahlbetonhülle und den Stahlmantelelementen parallel zur Grenzschichtlage/Trennebene nicht möglich ist.Conveniently, the steel shell elements and the reinforced concrete envelope are joined together so that a composite adhesion is achieved between the individual layers. In particular, in an impact-induced bending stress of such a sandwich composite, the largest proportion of the tensile and compressive stress occurring in the region of the liner, d. H. present externally relative to the neutral fiber. In this case, it is desirable and desirable if a relative movement between the layers of the sandwich structure, i. H. the reinforced concrete shell and the steel shell elements parallel to the boundary layer / separation plane is not possible.
Bei einer zweckmäßigen Variante des Verfahrens gemäß der Erfindung ist daher vorgesehen, die Stahlmantelelemente mit der Stahlbetonhülle zu verdübeln oder anderweitig zu einem Verbund zusammenzufügen.In an expedient variant of the method according to the invention is therefore intended to dowel the steel shell elements with the reinforced concrete envelope or otherwise put together to form a composite.
Besonders vorteilhaft ist es, wenn die Stahlmantelelemente mit einem Haftvermittler, vorzugsweise mit Vergussmörtel und/oder Faserzement hinterfüllt werden. Der Haftvermittler stellt zweckmäßigerweise eine stoffschlüssige Haftung zwischen dem Stahlmantelelementen und der Stahlbetonhülle her.It is particularly advantageous if the steel jacket elements are backfilled with an adhesion promoter, preferably with grout and / or fiber cement. The adhesion promoter expediently produces a cohesive adhesion between the steel shell elements and the reinforced concrete shell.
Die Stahlmantelelemente können sowohl innenseitig als auch außenseitig der Stahlbetonhülle vorgesehen werden.The steel shell elements can be provided both on the inside and on the outside of the reinforced concrete shell.
Bei einer zweckmäßigen Variante des Verfahrens gemäß der Erfindung ist vorgesehen, dass jeweils innenseitig und außenseitig gegenüberliegend angeordnete Stahlmantelelemente gegeneinander verankert werden.In an expedient variant of the method according to the invention it is provided that in each case inside and outside opposite arranged steel shell elements are anchored against each other.
Beispielsweise können jeweils innenseitig und außenseitig gegenüberliegend angeordnete Stahlmantelelemente gegeneinander verspannt werden, wobei bei einer Variante der Erfindung vorgesehen ist, dass die Stahlbetonhülle mit Ankerelementen, vorzugsweise mit Gewindestangen, vollständig durchsetzt wird und gegenüberliegend angeordnete Stahlmantelelemente mittels der Ankerelemente gesichert werden. Diese können beispielsweise mit Muttern gegen Unterlegplatten oder Unterlegscheiben oder auch durch Schweißverbindungen gesichert werden.For example, in each case inside and outside opposite arranged steel jacket elements are braced against each other, which is provided in a variant of the invention that the reinforced concrete envelope with anchor elements, preferably with threaded rods, is completely penetrated and oppositely disposed steel shell elements are secured by means of anchor elements. These can be secured, for example with nuts against shims or washers or welded joints.
Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels erläutert.The invention will be explained below with reference to an embodiment shown in the drawings.
