Der Erfindung liegt die Aufgabe zugrunde, ein Schleussystem zu schaffen, das bei einem wirtschaftlichen Einsatz den Durchlaß von Gegenständen verschiedener Form und/oder Größe gestattet.The invention has for its object to provide a lock system that allows the passage of objects of different shapes and / or sizes when used economically.

Die Aufgabe wird erfindungsgemäß durch einen verstellbaren Einsatz einer Lüftungstrennwand gelöst, der aus einer um ihren Mittelpunkt bewegbaren runden Scheibe besteht, die auf einer zu ihrem Mittelpunkt konzentrischen Kreislinie mit mehreren in ihrem Querschnitt unterschiedlichen Schleusöffnungen versehen ist.The object is achieved according to the invention by an adjustable use of a ventilation partition, which consists of a round disk which can be moved around its center and which is provided on a circular line concentric with its center with a plurality of lock openings with different cross sections.

Durch die Erfindung ist ein Schleussystem vorhanden, mit dem bei nur einer Ausschleusstraße Gegenstände unterschiedlicher Form und/oder Größe geschleust werden können, und das keinerlei Abdichtungsschwierigkeiten aufweist.The invention provides a lock system with which objects of different shapes and / or sizes can be passed with only one discharge line and which has no sealing difficulties whatsoever.

Vorteilhafte und zweckmäßige Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous and expedient developments of the invention result from the subclaims.

Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung nachstehend näher erläutert. Der besseren Übersicht halber wurde auf die Darstellung von Teilen verzichtet, die nicht zum Verständnis der Erfindung erforderlich sind.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. For the sake of clarity, parts that are not necessary for understanding the invention have not been shown.

Es zeigtIt shows

  • Fig. 1 ein Schleussystem in teilweise geschnittener Seitenansicht,1 is a lock system in a partially sectioned side view,
  • Fig. 2 das Schleussystem nach Fig. 1, in teilweise schematisch dargestellter Rückansicht.Fig. 2 shows the lock system of FIG. 1, in a partially schematic rear view.

Mit 1 ist eine senkrechte Lüftungstrennwand bezeichnet, die einen Arbeitsbereich in zwei separate, voneinander lüftungstechnisch getrennte Räume 2 und 3 unterteilt. Der Raum 2 ist mit einer offenen radioaktiven Belastung beaufschlagt, also kontaminiert, da sich in ihm zerlegte abgebrannte Brennelemente befinden, die z. B. als Brennstabbündel oder als gepreßte quadratische Brennelement-Strukturteile, sogenannte Preßlinge, ausgeschleust werden. Der Raum 3 ist kontaminationsfrei; er dient dem Beladen von endzulagernden Behältnissen 4 mit den auszuschleusenden radioaktiven Gegenständen 5. Die Lüftungstrennwand 1 weist eine Öffnung auf, vor der sich ein Einsatz 6 befindet, der mit zwei in ihrem Querschnitt unterschiedlichen Schleusöffnungen 7 und 8 versehen ist. Die Öffnung 7 weist einen quadratischen Querschnitt auf und dient zum Durchlaß von Preßlingen. Die Öffnung 8 weist einen Querschnitt in der Fornm eines an einer Seite gewölbten Trapezes auf und dient zum Durchlaß von Brennstabbündeln. Die Schleusöffnungen 7 und 8 sind in ihrem Querschnitt genau entsprechend den Maßen der endzulagernden Behältnisse 4 ausgearbeitet. Die Schleusöffnungen 7 und 8 erweitern sich zu einem Bereich, der zur Aufnahme eines aufblasbaren Dichtringes 9 dient. Der Einsatz 6 besteht aus einer runden Scheibe, bei der sich die Schleusöffnungen 7 und 8 auf einer zum Mittelpunkt der Scheibe konzentrischen Kreislinie befinden. Der scheibenförmige Einsatz 6 trägt auf seinem Umfang einen Zahnkranz 10, der mit einem Zahnrad 11 im Eingriff steht, das durch einen an der Lüftungstrennwand 1 befestigten Antrieb 12 drehbar ist. Der Einsatz 6 ist über einen Kugeldrehkranz 13 an der Lüftungstrennwand 1 befestigt. Der Kugeldrehkranz 13 ist zum Raum 3 hin durch einen Dichtring 14 abgedichtet. Der Dichtring 14 ist fernhantiert austauschbar und mit einem Ansatz 15 durch Schraubglieder 16 an der Lüftungstrennwand 1 befestigt. Die Schleusöffnungen 7 und 8 sind bei Nichtgebrauch durch abdichtende Schwenkhauben 17 verschlossen.1 designates a vertical ventilation partition which divides a work area into two separate rooms 2 and 3 which are separated from one another in terms of ventilation technology. The room 2 is exposed to an open radioactive load, ie contaminated, since there are broken down spent fuel elements, which, for. B. as fuel bundles or as pressed square fuel assembly structural parts, so-called compacts, can be discharged. Room 3 is free of contamination; it serves for loading containers 4 to be disposed of with the radioactive objects 5 to be discharged. The ventilation partition 1 has an opening in front of which there is an insert 6 which is provided with two lock openings 7 and 8 with different cross sections. The opening 7 has a square cross section and serves for the passage of compacts. The opening 8 has a cross section in the shape of a trapezoid arched on one side and serves for the passage of fuel bundles. The cross-section of the lock openings 7 and 8 are worked out exactly according to the dimensions of the containers 4 to be disposed of. The lock openings 7 and 8 widen to an area which serves to receive an inflatable sealing ring 9. The insert 6 consists of a round disk in which the lock openings 7 and 8 are located on a circular line concentric with the center of the disk. The disk-shaped insert 6 carries on its circumference a ring gear 10 which is in engagement with a gear wheel 11 which can be rotated by a drive 12 fastened to the ventilation partition 1. The insert 6 is on the turnstile 13 on the ventilation partition 1 attached. The ball slewing ring 13 is sealed off from the space 3 by a sealing ring 14. The sealing ring 14 can be exchanged remotely and is fastened to the ventilation partition wall 1 with a projection 15 by screw members 16. The lock openings 7 and 8 are closed by sealing swiveling hoods 17 when not in use.

Je nach dem, welche der Schleusöffnungen benutzt werden soll, und diese wird dann durch den drehbaren Einsatz 6 in Position gebracht, wird zur Benutzung dieser Schleusöffnung deren Haubendeckel fernbedienbar geöffnet und dann auch der Verschluß des Behältnisses 4, nachdem dieses an den Einsatz 6 über die Dichtung 9 angedockt wurde.Depending on which of the lock openings is to be used, and this is then brought into position by the rotatable insert 6, the hood cover is opened remotely to use this lock opening and then also the closure of the container 4, after this to the insert 6 via the Seal 9 was docked.
