£s war daher Aufgabe der vorliegenden Neuerung ,eine Vor· richtung zu schaffen, mit der es ttögliah ist, radioaktiv kontaminierte metallische Reaktorteile, wie Brennelementkästen^ Vergiftungsbleche und Incorelanzen, zu zerkleinern mit gleichzeitiger Volumenreduzierung voluminöser Abfallprodukte. Diese Vorrichtung muss insbesondere auch in Wasser becken unter Wasser verwendbar sein. It was therefore the task of the present innovation to create a device with which it is possible to comminute radioactively contaminated metallic reactor parts, such as fuel element casings, poisoning plates and Incorelances, while at the same time reducing the volume of voluminous waste products. In particular, this device must also be usable in water basins under water.

mass vor der Schere eine Presse anordnet und davor einen Führungstrichter anbringt.measured a press in front of the scissors and one in front of it Attaches guide funnel.

Anhand der schematischen Abbildung wird im folgenden eine beispielhafte Aus führungsform der Neuerung näher erläutert:The following is an example based on the schematic illustration Embodiment of the innovation explained in more detail:

Auf einem einheitlichen Gestell (l) befindet sich eine Presse (2) ] und eine Schere (3) - Die Presse (2) besteht aus zwei Batiken (4.5) mit einer Druckfläche von beispielsweise 36O mm Breite und 200 mn Höhe, wobei die Backenöffnung rund 210 mm beträgt. Einer der Pressebacken (4) ist mobil, der andere fest (5). Der mobile Backen (4) wird mittels seitlich angebrachter Führungsstangen wasserhydraulisch über Kolben und Zylinder bewegt. Nach Einstellung der entsprechenden Steuerventile kann er geöffnet und geschlossen werden. Der Pressdruck bei I30 bar beträgt rund 16 t. Die Presse hat die Aufgabe, die voluminösen Brennelementkästen zusammenzudrücken, um das Endlagervolumen zu reduzieren.A press (2) is located on a uniform frame (l)] and a pair of scissors (3) - The press (2) consists of two batiks (4.5) with a printing area of, for example, 360 mm wide and 200 mm high, the jaw opening being around 210 mm. One of The press jaw (4) is mobile, the other fixed (5). The mobile jaw (4) is operated by means of guide rods attached to the side Moved hydraulically via piston and cylinder. After setting the corresponding control valves, it can be opened and getting closed. The pressing pressure at 130 bar is around 16 t. The press has the task of compressing the voluminous fuel assembly boxes in order to reduce the volume of the final storage facility.

Die Schere (3) besteht aus einer festen (6) und einer mobilen Halterung (7) mit je einem Messer. Die Fchneidbreite beträgt z.B. 340 mm, die Messeröffnung 110 mm. Die Führung und Beweglichkeit der mobilen Halterung mit Messer beruht auf dem gleichen Prinzip wie die Presse. Der Schneiddruck bei I30 bar beträgt ebenfalls l6 ts Die mobilen und festen Messer sind austauschbar. Schneiden und Schneidenwinkel sind den zu zerkleinernden Reaktorteilen angepasst. The scissors (3) consist of a fixed (6) and a mobile holder (7), each with a knife. The cutting width is, for example, 340 mm, the knife opening 110 mm. The guidance and mobility of the mobile holder with knife is based on the same principle as the press. The cutting pressure at 130 bar is also l6 t s. The mobile and fixed knives are interchangeable. Cutting edges and cutting edge angles are adapted to the reactor parts to be shredded.

Die Schere hat die Aufgabe, die Brennelementkästen, Vergiftungsbleche und Inecrelanzen zu sehneiden und zu zerkleinern. The task of the scissors is to cut and shred the fuel assembly boxes, poisoning plates and increlances.

Über die Presse (2) und Schere (3) ist ein Führungstrichter (8) angeordnet, der die Einführung der zu zerkleinernden Abfallteile in die Presse (2) erleichtert.A guide funnel (8) is located above the press (2) and scissors (3) arranged, which facilitates the introduction of the waste parts to be shredded into the press (2).

In dem Gestell (l) befindet sich weiterhin ein Schienenwagen (9) mit einem Transferbehälter (lO). der die zerkleinerten, konta—In the frame (l) there is also a rail car (9) with a transfer container (10). the crushed, conta—

■inierten Abschnitte aufnimmt. Mit einem Antrieb kann der Schienenwagen (9) seitlich aus dem Gestell (l) herausgefahren und der Transferbehälter (lO) herausgenommen werden, um ihn in eine Umladewanne zu entleeren. Ein leerer Transferbehälter kann dann zurück in den Schienenwagen (9) gesetzt und unter die Schere (3) gefahren werden.■ Recorded sections. With a drive, the Rail carriage (9) moved out of the frame (l) to the side and the transfer container (10) can be removed, to empty it into a transfer bath. An empty transfer container can then be placed back in the rail car (9) and driven under the scissors (3).

Die Umladewanne dient z**r Aufnahme der zerkleinerten Abschnitte, die anschliessend in einen Endlagerungsbehälter umgeladen werden. The transfer tray is used to accommodate the shredded sections, which are then transferred to a disposal container.

Alle Bauteile dieser Vorrichtung sind aus nichtrostendem Material, da sie für längere Zeit Ablagerungsbecken der Kernkraftwerke abgestellt werden müssen.All components of this device are made of rustproof material, as they are storage basins of nuclear power plants for long periods of time must be turned off.

Die neuerungsgemässe Vorrichtung ist über Hochdruckschläuche uit den Steuerventilen und einem Hochdruckaggregat verbunden, die" sich ausserhalb des Wasserbeckens befinden und mit denen die entsprechenden Manipulationen, wie Pressen, Schneiden und Transport der Abfälle im Wasserbecken durchgeführt werden können.The device according to the innovation is via high-pressure hoses uit connected to the control valves and a high pressure unit, which "are outside the water basin and with which the corresponding manipulations, such as pressing, cutting and transport the waste can be carried out in the water basin.
