Definitions
- Containers with a body with toxic and / or radioactive contamination and method for producing such a container are provided.
- the invention relates to a container with a body which has a surface with toxic and / or radioactive contamination, and with a container matrix which covers the surface with contamination and which consists of hardened organic foam.
- the object of the invention is to at least largely avoid dismantling the body, which has a surface with toxic and / or radioactive contamination.
- the container matrix of the container according to the invention which consists of hardened organic foam, fixes the toxic and / or radioactive substances on the contaminated surface, so that there are none
- the container matrix made of hardened organic foam also covers the uncontaminated surface of the body in the container. Furthermore, it is favorable if the container matrix adheres at least to the surface that has the contamination. It is too very cheap if the body in the container is completely encased in a hardened foam container matrix.
- a container with a body that has an interior, the wall of which forms the surface that contains the contamination and that is at least partially filled with a container matrix made of hardened organic foam.
- This cured organic foam not only fixes toxic and / or radioactive substances on the wall of the interior, but also objects that are located in this interior and that can also have toxic and / or radioactive contamination.
- the body in the container is a glove box or a tank and has an interior with a contaminated wall.
- Container matrix made of hardened organic foam in the container can be a rigid polyurethane foam.
- the invention further relates to a method for producing a container with a body, in particular a glove box or tank, with an interior, the wall of which has a surface with toxic and / or radioactive contamination and to which an opening leads which has a membrane, in particular a glove, is covered, through which an injection needle is inserted, by means of which reaction liquids for forming a container matrix consisting of hardened foam are injected into the interior.
- a body in particular a glove box or tank
- an interior the wall of which has a surface with toxic and / or radioactive contamination and to which an opening leads which has a membrane, in particular a glove, is covered, through which an injection needle is inserted, by means of which reaction liquids for forming a container matrix consisting of hardened foam are injected into the interior.
- reaction liquids for forming a container matrix consisting of hardened foam are injected into the interior.
- all cavities in the interior of the body can be filled with hardened organic foam.
- Fig. 1 shows a partially sectioned side view of a
- Fig. 2 shows partially cut one from a
- FIG. 3 shows a cross section through the packaging box according to FIG. 2.
- Fig. 4 shows a partially sectioned front view of a
- FIG. 5 shows a partially sectioned side view of the steel container according to FIG. 4.
- a glove box represents a body 2 with an interior.
- This glove box has an observation window 3, covered connecting pieces 4 and 5 for gloves and discharge bags, an air inlet 6 and an air outlet 7.
- the air inlet 6 is closed, while the air outlet 7 is open, so that exhaust air can be drawn off through it with an exhaust pipe 12 via a filter 7a for separating aerosols.
- a mixer 8 is located in the interior of the glove box. Both the mixer 8 and the walls of the interior of the glove box are contaminated with radioactivity.
- the connecting piece 5 forms an opening to the interior of the glove box and is covered on the outside with a membrane, for example a plastic film, through which an injection needle 9 is inserted.
- a supply hose 10 is connected, through which reaction liquids can be fed into the interior of the glove box via the injection needle 9.
- a reaction liquid consists, for example, of a mixture of a polyhydroxy compound with an aromatic isocyanate resin and an addition of activation and stabilizing substances and water. The amount of water determines the amount and compressive strength of the cured foam that forms from the mixture.
- the mixture is pumped into the interior of the glove box via the supply hose 10 and the injection needle 9. It is distributed as a liquid phase on the floor of the interior of the glove box.
- the mixture C0 2 begins to split off, which leads to the foaming of the organic part of the liquid mixture.
- the air displaced in the interior of the glove box leaves the interior of the glove box via the exhaust air connector 7 and the filter 7a, in which air-borne radioactive particles are retained.
- the foam-like inflated by the C0 2 mixture of the reactants eventually filled the entire interior of the glove box with all the cavities, and finally cures to a pressure-resistant container matrix 11 made of foam out of the interior of the glove box does not only adhere to the surfaces of the wall firmly and thereby radioactive Contamination firmly integrates, but also completely envelops the mixer 8 with its contamination, so that this mixer 8 is rigidly fixed in the interior of the glove box.
- the glove box according to FIG. 1 is then converted with an outer container 13, which is a box recognizable in FIG. 2.
- the glove box is completely surrounded by a container matrix 13a made of hardened foam, which was produced in exactly the same way as the hardened foam in the interior of this glove box.
- spacers 15 can be provided in the box 13, which fix the glove box until the foam of the container matrix 13a fills all cavities in the box 13 and has hardened.
- the box 13 according to Figures 2 and 3 is portable after the foam has cured. It represents the waste product with the glove box in it, which can be set in a steel repository container 16 that can be seen in FIGS. 4 and 5, in which the box 13 is completely encased in concrete 17, which has all the cavities between the box 13 and the steel container 16 fills.
