Embodiment Construction

[0025] The diagram graphically illustrates the method according to the invention for depressurizing and inerting waste containers 1 for radioactive waste, in particular for weakly and moderately radioactive waste. According to the invention, the adapter 2 with the adapter inner volume 3 is connected to the container 1 and, more precisely, the adapter 2 is preferably fixed in this exemplary embodiment on the container lid 4 of the container 1 . The adapter 2 is a component of an adapter device 6 , which will be explained in more detail below, which additionally has a pump or vacuum pump 7 as well as an inert gas source 8 , a vacuum line 10 and an inert gas line 11 . Furthermore, a component part of the adapter device 6 is also the mixing nozzle 9 explained further below.

[0026] The adapter 2 has an adapter head 12 and a surrounding adapter wall 13 adjoining it. Preferably and in this exemplary embodiment, the underside 14 of the adapter 2 facing the container 1 is designed t...

Abstract

The invention relates to a method for pressure relief and inerting of refuse container for radioactive waste. An adapter with an adapter inner volume (3) is connected to a container (1), in particular to the container cover (4). Subsequently, the adapter (2) is filled with an inert gas under an overpressure and subsequently a connection between the container interior (5) and the adapter inner volume (3) is established, and then the pressure difference between the pressure in the container interior (5) and the overpressure in the adapter inner volume (3) forms a mixed pressure difference. The mixed pressure in the container interior (5) is relieved, and then a vacuum is generated in the container interior (5), and gas removed from the container interior (5) is replaced by inert gas.

Description

technical field [0001] The invention relates to a method for depressurizing and inerting waste containers for radioactive waste, in particular for weakly and moderately active radioactive waste. Furthermore, the invention relates to an adapter device for depressurizing and inerting waste containers for radioactive waste. Waste containers for radioactive waste are usually made of metallic materials. The waste container has a container base, a container casing connected thereto and at least one container cover. Such a waste container must meet certain safety requirements and, in addition to ensuring adequate shielding, must also be designed to be sufficiently pressure-resistant. Then instead of the term waste container the term container is also briefly used. Background technique [0002] It is known in practice to package various types of radioactive waste in waste containers. The waste container is designed as a transport and / or storage container. The invention is based...
