Description

The The invention relates to a device for processing a bearing and / or transport container for the Picking up and / or transporting radioactive materials, in particular in a closed chamber, in particular a vacuum chamber.

In Reprocessing plants for radioactively contaminated materials become storage and / or transport containers for the Absorption and / or transport of radioactive materials regularly by means of complicated wet process using water or other liquids cleaned. However, because of the containers in particular at a Glazing plant by filling the be called vitrified radioactive waste in the containers of very high temperatures are exposed, for example, arise on surfaces of the containers strongly adhering and partly diffused into the material layers for example, from Metallalloxiden, which by means of the usual Cleaning not always complete or only under very large Have the effort removed.

adversely is also that big Amounts of liquid waste arise, which in turn contains radioactive substances, so that additional Waste arises and this in turn in a complex reprocessing process must be disposed of.

task The present invention is therefore, in the processing of a Storage and / or transport container for the Recording and / or transport of radioactive materials to proceed, that a flexible processing with small amounts of waste possible becomes.

When solution is a device for processing a storage and / or transport container for recording and / or the transport of radioactive materials, in particular in a closed chamber, in particular a vacuum chamber, the device being a robot and / or a manipulator has, in particular a multi-axis robot, for processing the container with one or more types of processing, the robot and / or the manipulator one or more particular interchangeable laser beam processing devices which are operable in combination or alternatively, and with respectively predetermined working values, in particular laser power and / or laser wavelength, adapted to the respective processing.

By this device is it possible a nearly contactless and fast processing of the containers to ensure, where no waste liquids attack. Due to the contactless work passes substantially no radioactive load on the robot or the manipulator and the editing tools, so that any repair is simplified.

Furthermore The chamber in which the processing of the containers due to the radioactive Strain must be made smaller, which also causes the areas to be decontaminated and the environmental impact is reduced in a chamber cleaning or a chamber remodeling.

Advantageous is in particular the use of the device in a glazing system in a reprocessing plant, since there for example by the high glass transition temperatures when filling into the containers a tarnishing of the surface and a diffusion of radioactive substances happen quickly can and a low-waste and thorough Cleaning and editing is very important.

• – Schweißen mit einer vorbestimmten Laserleistung, insbesondere Verschweißen eines Behältnisdeckels mit einem Behältniskörper, und/oder
• – Reinigung bzw. Dekontamination einer Oberfläche des Behältnisses und/oder
• – Markierung der Oberfläche des Behältnisses.

This is especially true when the container is a mold, in particular made of stainless steel, in the first glazing in the glazing plant hot glazed material, in particular comprising highly radioactive cleavage products to fill. On the stainless steel body, an oxide layer forms on the outer surface, which can be eliminated by the proposed device quickly, safely and low waste. In addition, the types of processing by the laser processing devices, which are set up in particular on the robot hand, are exemplary:

• - Welding with a predetermined laser power, in particular welding a container lid with a container body, and / or
• - Cleaning or decontamination of a surface of the container and / or
• - Marking the surface of the container.

At the welding By means of the laser, a high operating speed is achieved and the energy is strongly concentrated, leaving adjacent area thermally only slightly be charged.

The Marking can be carried out without contact by means of the laser, is durable, abrasion resistant and temperature resistant, without any further radioactively activatable substances aufgerbachtr be. In addition is to use the process on a wide variety of surfaces.

The cleaning by means of the laser has the great advantage that it produces no contaminated wastewater compared to conventional wet methods using brushing / ultrasound or rinsing. In addition, this secondary waste creates high energy consumption and high material usage. The laser cleaning removes the radioactive dirt and the oxide layer or the tarnishing colors. The sudden evaporation causes the surface layer to burst off.

Advantageous it is, if blasted off by the laser processing material over a Suction device, in particular in connection with the laser processing device, is to be sucked off and in particular is to be fed to a filter, the distance to the container surface in particular advantageously about 500 mm.

Advantageous it is when the robot with a changer to change the laser processing devices is equipped and the exchanged Laserbear processing devices advantageously on a particular be kept separate storage.

Advantageous It is when the robot is with a hose package for particular equipped with laser light guides, protective gas conductors and / or compressed air conductors is, in particular, the laser lines on a boom with held a balancer.

Advantageous it is when the laser beam sources outside the chamber, preferably in an intervention room, are set up and the laser light guides from there by means preferably against a predetermined air pressure difference sealed wall penetrations to lead into the chamber are and the control devices, switching devices and / or power supply devices outside the chamber, preferably in the intervention room, set up are and the electrical cables over preferably sealed against a predetermined air pressure difference wall bushings to lead into the chamber are. This makes a simple repair possible and the big devices become not contaminated.

Advantageous it is when the robot is movable on rails on a chassis is lockable and in particular in the respective working position and in particular in an adjacent intervention room along the rails is convertible.

Advantageous it is when a turntable for rotating the container to be processed, which are in particular cylindrical, for processing by the robot is provided, in particular, several containers to be positioned on it are that they turn one after another by turning the turntable to the machining position to bring.

Advantageous is it when the container by means of a container gripper to position on it and to remove it.

Advantageous It is when a magazine for shutdown and cooling of the processed containers in the chamber is provided.

Advantageous it is when a lid magazine for providing the applied to the container body Cover is provided.

The Task is also solved by a method for processing a storage and / or transport container for the Inclusion and / or transport of radioactive materials, in particular in a closed chamber, in particular a vacuum chamber, wherein provided for processing a robot and / or a manipulator is, in particular a multi-axis robot, with one or more Laser processing modes that are used in combination or alternatively and each with predetermined working values, in particular laser power and / or laser wavelength, work on the respective processing, in particular with a Device according to one of the preceding claims 1 to 14.

The Task is also solved by using a robot, especially a multi-axis one Robot, and / or a manipulator for processing a storage and / or transport container for the Picking up and / or transporting radioactive materials, in particular in a closed chamber, in particular one Vacuum chamber, in a glazing plant of a reprocessing plant, by means of a laser beam processing device, in particular for contactless decontamination, labeling and welding of the container, in particular according to a method according to claim 15 and in particular using a device according to one of claims 1 to 14th
