Definitions

the invention relates to a method for processing radioactive waste stored in a container.
the invention also relates to an arrangement for processing radioactive waste stored in a container.
inorganic and organic radioactively contaminated waste is generated and has to be disposed of.
radioactive materials include e.g. Ion exchangers, evaporator concentrates, sludge, metallic components, rubber, plastic or even clothing.
a container in which the radioactive waste is surrounded by a matrix, that is, embedded in a container.
the containers are for their part inserted into, for example, concrete or cast in concrete.
a container can also comprise a barrel with an inliner made of concrete, in which the radioactive material is embedded with the matrix.
Bitumen is also used when the waste is not in drums, but e.g. be stored in containers or chambers, so-called compartments.
the container is first severed in order to ensure that pyrolysis of the radioactive waste can be carried out without any problems, even if the radioactive waste is in a container that e.g. has a concrete shell on the outside and / or a liner on the inside, i.e. a lining made of concrete, the radioactive waste itself preferably being stored in a matrix which in turn e.g. is received by a container which is surrounded by a concrete wall, without this being a mandatory feature.
a container is, for example, an envelope such as a barrel, which is optionally surrounded by a jacket made of concrete or other shielding material or has such a lining inside and in which the radioactive material is embedded in a matrix.
a container can also be a receptacle made of concrete or other shielding material in which the matrix with the radioactive material is stored. Even a barrel without a concrete shield is a container in which the matrix with the radioactive waste is placed.
the container is cut through in an anteroom upstream of the reaction chamber, such as the loading room, e.g. with a cutting rope.
a severing can be carried out in the axial and / or radial direction, preferably in the axial direction.
the package parts thus available are then positioned with their cut surface on a receptacle which has openings.
This can be a grate or a grid that in turn covers a tub.
a receptacle formed in this way is then conveyed into the reaction space.
one or more additional measures are provided during pyrohydrolysis in order to gasify volatilizing radioactive waste and organic embedding material. It is provided in particular that oxygen and / or CO 2 is introduced into the reaction space during the pyrolysis, the proportion of oxygen preferably being less than stoichiometric, optionally up to a maximum of stoichiometric.
a corresponding regulation can also take place for the oxygen and / or CO 2 proportion to be introduced.
the pyrolysis is switched off depending on the oxidizable substance present in the exhaust gas.
the superheated steam or superheated steam with O 2 and / or CO 2 is specifically directed to the area or areas in the reaction chamber, i.e. inside the furnace, in which the radioactive waste is located.
the water vapor can be circulated in a targeted manner within the reaction chamber, whereby a volume flow is generated which corresponds to a multiple of the feed.
the invention is also characterized in that the atmosphere in the reaction space is swirled by means of one or more fans.
the fan or fans can be set in rotation in the reaction space by means of the introduced gaseous fluid, such as water vapor and / or O 2 and / or CO 2 .
radioactive waste is processed that is embedded in an organic matrix, such as bitumen, epoxy resin, urea resin.
the invention is of course not restricted by the fact that the radioactive waste was homogeneously mixed with bitumen.
a heterogeneous storage in a matrix can also have taken place. This applies in particular to metals, building materials, animal bodies or glass that are coated with a matrix material such as bitumen.

a container such as a standard barrel, such as 2001 barrel
gaseous fluid such as water vapor and / or O 2 and / or CO 2
a lance having a nozzle or a spray head can be used, via which the fluid is discharged in the direction of the bottom of the receptacle so that the fluid is then deflected from the bottom in the direction of the cut surface.
Receivers for the container part (s) should have a tub geometry that is designed in terms of volume such that the entire contents of the container part or parts received, such as the container or barrel halves, which can be surrounded by concrete on the circumference, can be accommodated.
a temperature in the range between 200 ° C. and preferably up to 800 ° C. is set within the reaction space. Superheated steam is then supplied to the room.
oxygen and / or CO 2 can additionally be fed into the reaction space.
the oxygen content is in particular sub-stoichiometric, optionally up to a maximum of stoichiometric.
a proprietary inventive proposal provides that the gaseous fluid, such as water vapor and / or O 2 and / or CO 2 , be directed in the reaction space.
so-called steam jets can be used, which are designed as nozzles through which the gaseous fluid, such as at least the water vapor, is introduced into the reaction space.
the nozzles suck in atmosphere from the reaction chamber, so that an internal circuit is created and thus a volume flow that is a multiple of the feed.
the nozzles can work like venturi nozzles.
An exhaust gas pipe leads from the reaction chamber and leads to afterburning.
the proportion of oxidizable substances is determined. The higher the proportion, the higher the proportion of organic substances that have not yet been pyrolyzed. This can be determined, for example, by determining the heat development during the oxidation of the exhaust gas.
the water vapor supply or the temperature in the reaction space or the oxygen or CO 2 supply can then be regulated.
the exhaust gas is mixed with air and burned.
the oxygen is measured after the post-combustion has exited. This should be kept at a constant value, for example 5% by volume to 7% by volume, in particular 6% by volume.
the air supplied to the afterburning is regulated accordingly. According to the invention it is then provided that, depending on the air supplied, the temperature and / or the amount of water vapor and / or the supply of oxygen or CO 2 into the reaction chamber, i.e. inside the furnace, is regulated or even a shutdown takes place, for example to avoid the risk of a Rule out an explosion.
the amount of air supplied to the post-combustion is a measure of the combustible fraction present in the pyrolysis gas, such as organic matter, H 2 , CO.

the invention is also characterized by a method for regulating the water vapor and / or O 2 and / or CO 2 and / or temperature in the reaction chamber to be supplied to the reaction chamber by determining the combustible substance contained in the pyrolysis gas.
the invention is inventively characterized in that the regulation of the gaseous fluid to be fed to the reaction chamber is carried out redundantly and diversely, i.e. on the one hand depending on the air to be fed to the post-combustion and on the other hand on the oxygen content in the pyrolysis gas.
Gaseous fluid contains water vapor and / or O 2 and / or CO 2 , it being possible to use CO 2 instead of water vapor.
gaseous fluid such as at least water vapor
a nozzle such as a Venturi nozzle
gaseous fluid such as at least water vapor
gaseous fluid is conducted within the reaction space in such a way that targeted radioactive waste or the matrix is acted upon with water vapor.
the invention is also characterized in that the exhaust gas is fed to an afterburning process, with its oxidizable portion being determined before the afterburning of the exhaust gas and, depending on the oxidizable portion, supply of gaseous fluid such as water vapor and / or oxygen and / or CO 2 Supply to the reaction space and / or the temperature in the reaction space is regulated, the regulation also including switching off the pyrolysis.

the atmosphere is, in particular, a water vapor atmosphere to which oxygen and / or carbon dioxide is optionally supplied in a targeted manner.
water vapor is used below, although - as explained above - other gaseous fluids can also form the atmosphere.
the device can be a nozzle, via which water vapor can be supplied from the outside to the reaction space with simultaneous suction of water vapor atmosphere from the reaction space.
the Venturi principle is used.
the receptacle has a grid or a grate with the perforations, which runs at a distance from a tub-shaped base or support, and that the device is a rod body, such as a lance, with a nozzle and / or spray head which or which the gaseous fluid can be directed in the direction of the base or support.
the invention is also characterized in that the reaction space has a connection for the oxygen and / or carbon dioxide to be supplied to the reaction space in a preferably sub-stoichiometric, optionally up to a maximum of stoichiometric amount.

Measuring device of the post-combustion chamber to be fed air amount is regulated, which in turn is a control variable for the reaction chamber to be fed gaseous fluid and / or temperature to be set in the reaction chamber.
the invention relates to a method and an arrangement for processing radioactive waste that is present in a container and stored in a matrix by means of pyrolysis.
the invention is described on the basis of hydropyrolysis, that is to say pyrolysis with water vapor.
water vapor instead of water vapor, however, CO 2 can also be used.
water vapor is used below, even if water vapor is also to be understood as a synonym for CO 2 .
the arrangement comprises an oven 12 which provides a reaction space 40 and in which the hydropyrolysis is carried out.
the oven 12 is heated to a temperature between preferably 400.degree. C. and 800.degree.
Superheated steam is then introduced into the furnace 12 via feed lines, the steam being introduced at a temperature which should correspond to that in the furnace interior, that is to say in the reaction chamber 40.
a loading space 14 is arranged upstream of the pyrolysis furnace 12 and a sorting space is arranged downstream, both of which are shielded.
the radioactive waste to be processed is embedded in a matrix that is located in a barrel 18 that forms a container, without this restricting the teaching according to the invention.
a matrix that is located in a barrel 18 that forms a container.
Other organic matrix materials or even inorganic matrix materials are also possible.
Compartments or containers made of concrete can also be used as the container or parts thereof, to name only exemplary containers.
the barrels can be standard barrels. Independently of this, the barrels can be surrounded by a concrete jacket.
the container - hereinafter referred to simply as barrel 18 - is severed before it is introduced into the furnace 12. This takes place in particular in the pre-loading or loading space 14, as shown in principle in FIG Fig. 1 is shown.
the barrel 18 is fed to a separating device 20, which is a cutting rope 22 or another one Cutting through the barrel 18 enabling separating device acts.
the barrel 18 is cut through in an upright position in the axial direction, so that two barrel halves 24, 26 are then present.
the separated sections are spread or pulled away from one another.
the barrel halves are then placed with their cut surface on a grate or grid 30 which covers a trough-shaped receptacle 32.
the receptacle 32 is then conveyed into the furnace 12 in order to carry out the pyrolysis.
the receptacle 32 can be transported from the loading space 14 into the furnace 12 by means of a transport means such as a carriage 35.
the Fig. 3 shows, purely by way of example, that the barrel 18 is cut through in an upright position in the axial direction by means of the cutting cable 22.
the cutting rope 22 is guided as an endless rope over pulleys and cutting drives or devices 23, 25 in such a way that the barrel 18 can be cut through in the axial direction.
the inorganic inert materials include solids e.g. from evaporator concentrates, phosphates, sulfates or borates of sodium, calcium etc.
Fig. 2 In order for the water vapor to get sufficiently close to the waste to be gasified, according to Fig. 2 provided that the water vapor hits the cut surface 28 via so-called lances 34, 36 through the grid 30, that is, through its openings.
the lances 34, 36 which can have nozzles or spray heads at their ends, are directed in the direction of the bottom surface of the tub 32, so that the water vapor is thereby deflected in the direction of the cut surface 28.
Steam can also be introduced into the reaction space 40 via openings, usually in the form of openings. Fans can be provided for support.
the proportion of oxygen is preferably substoichiometric in order to avoid the risk of burning or an explosion.
the furnace 12 is shown purely in principle, which is connected via the exhaust gas line 42 to an afterburning chamber 74, to which air is supplied via a line 76.
the oxygen content of the gas (line 78) leaving the post-combustion chamber 74 is determined via a first measuring device 80, the amount of air to be supplied via the line 76 being adjusted such that the oxygen content of the gas flowing out is constant or almost constant.
the oxygen content should be around 6% by volume.
the amount of gaseous fluid, that is to say water vapor, fed to the furnace 12 is in turn regulated as a function of the amount of air fed to the post-combustion chamber 74, it also being possible to regulate the proportion of O 2 and CO 2 . This is illustrated by the connection 84.
a further measuring device 86 can be present in the pyrolysis gas line 52 leading to the post-combustion chamber 74 ( Fig. 7 ), in order to determine the proportion of oxidizable constituents in the pyrolysis gas, for example by means of a sensor 86 which measures the heat development during oxidation.
This portion can also be used as a manipulated variable (connection 88) for the steam and / or oxygen and / or CO 2 to be supplied to the furnace 12 and / or the setting of the temperature in the furnace 12.
both the amount of air to be fed to the post-combustion chamber 74 and the proportion of the oxidizable components contained in the pyrolysis gas are used as manipulated variables, so that redundant, diverse control is possible.
a related setting or regulation can also take place as a function of the air supplied to the afterburning.
the furnace 12 is cooled so that the barrel halves are then fed to the sorting room, in which the remaining inorganic constituents are sorted and the barrels are further cut up by means of manipulators.
the components are transferred to containers according to the determined radioactivity, which are then disposed of in accordance with the relevant regulations.
the trough-shaped supports 32 are returned to the loading space 14 via a conveying device for receiving new barrel halves 18.
the invention also covers when CO 2 is used for pyrolysis instead of water vapor.
