Description

Vorrichtung mit einem Transportbehälter und einem diesen aufnehmenden SchutzbehälterDevice with a transport container and a receiving container Protective container

Die Erfindung betrifft eine Vorrichtung mit einem Transportbehälter und einem diesen aufnehmenden Schutzbehälter, wobei Anschlagzapfen am Transportbehälter durch Laschen eines Hebezeugs greifbar sind.The invention relates to a device with a transport container and a protective container receiving it, wherein Stop pin on the transport container by lashing a hoist are tangible.

Ein solcher Transportbehälter kann zum Transport von Brennelementen eines Kernreaktors dienen. Er wird direkt in einem Lagerbecken für Brennelemente unter Wasser gefüllt, das radioaktive Partikel enthalten kann. Damit solche Partikel auf der äußeren Oberfläche des Transportbehälters nicht dauerhaft anhaften können, befindet sich der Transportbehälter in einem Schutzbehälter. Nach dem Beladen des Transportbehälters wird der Raum zwischen Transportbehälter und Schutzbehälter mit sauberem Wasser gespült. Wenn dann der Transportbehälter außerhalb des Lagerbeckens aus dem Schutzbehälter herausgenommen wird, ist die äußere Oberfläche des Transportbehälters gereinigt.Such a transport container can be used to transport fuel elements serve a nuclear reactor. It will be in one Storage pool for fuel elements filled under water, the radioactive May contain particles. So that such particles on the outer surface of the transport container is not permanent can adhere, the transport container is in one Protective container. After loading the transport container the space between the transport container and protective container rinsed clean water. Then if the shipping container is outside of the storage tank removed from the protective container is the outer surface of the shipping container cleaned.

Ein derartiges Verfahren ist aus der US 3,917,953 bekannt. Dabei sind sowohl der Transportbehälter, als auch der Schutzbehälter als stabile tragbare Behälter ausgebildet, die beide Anschlagzapfen für ein Hebezeug aufweisen. Der Schutzbehälter muss sogar sehr stabil gebaut sein, da das Hebezeug an ihm angreift und er beim Herausheben aus dem Becken den gesamten beladenen Transportbehälter trägt.Such a method is known from US 3,917,953. Both the transport container and the protective container are included designed as a stable portable container, both Have stop pins for a hoist. The protective container must even be built very stable, because the hoist on it attacks and when he is lifted out of the pelvis the whole loaded transport container.

Es ist auch schon vorgeschlagen worden, als Schutzbehälter ein sogenanntes Kontaminationsschutzhemd vorzusehen, das jedoch den Transportbehälter nur mit Ausnahme der Anschlagzapfen umgibt, da diese für das Hebezeug zugänglich sein müssen. It has also been proposed as a protective container to provide a so-called contamination protection shirt, however the transport container only with the exception of the stop pin surrounds, since these must be accessible for the hoist.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, bei der einerseits auch die Anschlagzapfen des Transportbehälters vor Kontamination geschützt sind und andererseits kein aufwendiger und teurer Schutzbehälter erforderlich ist, an dem ein Hebezeug angreift.The invention has for its object a device specify, on the one hand, the stop pin of the Transport containers are protected from contamination and on the other hand no complex and expensive protective container required that is being attacked by a hoist.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, dass mit dem Schutzbehälter Anschlagteile verbunden sind, die mit dem Hebezeug oberhalb der Laschen mechanisch fest verbindbar sind, und dass zwischen dem Transportbehälter und dem Hebezeug, sowie zwischen dem Hebezeug und dem Schutzbehälter und, wo es möglich ist, direkt zwischen dem Transportbehälter und dem Schutzbehälter Abdichtelemente anordenbar sind.The object is achieved according to the invention in that the protective container stop parts are connected to the The lifting gear can be mechanically connected above the brackets and that between the transport container and the hoist, as well as between the hoist and the protective container and, where possible, directly between the transport container and the protective container can be arranged sealing elements.

Mit den Anschlagteilen wird der Vorteil erzielt, dass der Schutzbehälter an das gleiche Hebezeug angehängt werden kann, das schon den Transportbehälter anheben soll. Die Anschlagteile sind dabei nur so stabil auszuführen, dass sie das Gewicht des Schutzbehälters und der Flüssigkeit, die sich zwischen den beiden Behältern befindet, tragen. Das Hebezeug greift weiterhin direkt an dem schweren Transportbehälter an.The advantage of the stop parts is that the Protective container can be attached to the same hoist, that should already lift the transport container. The stop parts are only so stable that they carry the weight the protective container and the liquid that is between in the two containers. The hoist continues to attack directly on the heavy transport container.

Damit der Zwischenraum zwischen dem Transportbehälter und dem Schutzbehälter trotzdem abgedichtet werden kann, sind die genannten Abdichtelemente vorgesehen. Sie dichten den Spalt zwischen den beiden Behältern im oberen Bereich ab. Im Bereich des Hebezeuges sind Abdichtelemente vorgesehen, die einerseits einen Spalt zwischen Transportbehälter und Hebezeug und andererseits einen Spalt zwischen Hebezeug und Schutzbehälter überdecken.So that the space between the transport container and the Protective containers can still be sealed, are the mentioned Sealing elements provided. They seal the gap between the two containers in the upper area. In the area of the hoist sealing elements are provided, on the one hand a gap between the transport container and the hoist and on the other hand a gap between the hoist and the protective container cover up.

Mit der Vorrichtung nach der Erfindung wird der Vorteil erzielt, dass der Transportbehälter bis oberhalb der Anschlagzapfen für das Hebezeug durch den Schutzbehälter umschließbar ist, und dass trotzdem der Schutzbehälter nicht so ausgelegt sein muss, dass ein Hebezeug an ihn angreifen und ihn beladen mit dem Transportbehälter anheben kann. Man erzielt mit einfachen Mitteln einen weitgehenden Schutz des Transportbehälters vor einer Kontamination seiner äußeren Oberfläche.With the device according to the invention the advantage is achieved that the transport container is above the stop pin can be enclosed by the protective container for the hoist and that the protective container is not designed so must be that a hoist will attack it and load it can lift with the transport container. You can achieve with simple Means extensive protection of the transport container from contamination of its outer surface.

Die Abdichtelemente, die mit dem Schutzbehälter verbindbar sind, weisen beispielsweise Dichtlippen auf, zum Anlegen auf dem oberen Rand des Schutzbehälters. Solche Dichtlippen sind vorteilhafter Weise schnell und zuverlässig positionierbar.The sealing elements that can be connected to the protective container are, for example, have sealing lips for application the top of the protective container. Such sealing lips are can be positioned quickly and reliably in an advantageous manner.

Der Raum zwischen dem Schutzbehälter und dem Transportbehälter ist beispielsweise mit einem Anschluss für Deionat verbunden. Dadurch kann der Zwischenraum gespült und von radioaktiven Partikeln befreit werden, bevor die beiden Behälter gemeinsam aus einem Lagerbecken herausgehoben werden und anschließend der Transportbehälter aus dem Schutzbehälter gehoben wird. Der Transportbehälter ist dann frei von Kontaminationen.The space between the protective container and the transport container is connected, for example, to a connection for deionized water. This allows the space in between to be rinsed and radioactive Particles are freed before the two containers be lifted out of a pool together and then the transport container is lifted out of the protective container becomes. The transport container is then free of contamination.
