Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solidification treatment facility for various radioactive wastes generated from a nuclear power plant or the like, and more particularly to a solidification treatment facility for solidifying multiple types of wastes in the same facility.

[0002]

2. Description of the Related Art Radioactive waste generated during the operation of a nuclear power plant is classified into liquid waste, slurry waste, miscellaneous solid waste, and the like. Currently, some of these wastes are solidified, and some of them are stored in tanks or drums.

Generally, a large amount of liquid waste is generated,
Since it is difficult to store in a tank for a long time due to the capacity of the tank equipment, the drum can is mixed with cement and solidified. However, if the mixture is kneaded with cement in a liquid state, the number of drums generated is large, so the waste liquid is dried and only the waste is taken out as powder, and this is compression molded into pellets to reduce the volume of the waste. Technology (volume reduction technology) is adopted. However, the pelletized waste is not solidified because the final disposal method has not been determined, and is stored and stored in the form of pellets.

Further, as the slurry-like waste, used ion-exchange resin (granular or powdery) is generated, but most of it is stored and stored in the tank because the final disposal has not been finalized.

On the other hand, of the miscellaneous solid waste, combustible waste generated from the power plant is incinerated in an incinerator. The incinerated ash generated by this incineration process is not solidified for the same reason as the above-mentioned waste, but is filled and stored in a drum can. Non-combustible miscellaneous solid waste, such as replacement parts at the time of periodic inspections of equipment in power plants and waste materials when equipment is remodeled, is currently stored in storage bins filled in drums.

By the way, radioactive waste will be received at the storage center in Shimokita, which started operation in 1992, and the waste that had been stored without solidification until now has been solidified and stored. The need has arisen for the solidified body to meet the acceptance criteria at the center.

At present, a kneading solidification method and an injection solidification method are considered as solidification methods for radioactive waste. The kneading and solidifying method is a method of kneading and solidifying a waste and a solidifying material as described in, for example, JP-A-58-169000, and the waste to which this solidifying method is applicable is not kneaded. Possible particles and powders of used ion-exchange resin. The injection and solidification method is as described in JP-A-56-151400, JP-A-60-3597, JP-A-3-128698, JP-A-4-128698, and the like.
This is a method of filling waste in a drum in advance and then injecting a solidifying material from above to solidify. In the case of this method, a device for preliminarily filling the drum with waste is required. Further, the waste to which the injection solidification can be applied is a pellet waste or a non-combustible miscellaneous solid waste such as a pipe in which the solidifying material can flow down the waste gap.

[0008]

As described above, with the start of acceptance at storage centers in Shimokita, it becomes necessary to subject the waste that has been stored without solidification treatment to solidification treatment. Came. However, there are many kinds of wastes that are not solidified at present and are stored and stored, and it is a great cost burden to install a dedicated solidification processing facility for each waste as in the above-mentioned conventional technique.

[0009] Further, if a dedicated solidification treatment facility is used, the amount of waste filling per drum can can be improved, while a large amount of waste is already solidified like concentrated waste liquid, The amount of waste remaining in the power plant at present is not so large, but it has the characteristic that there are many types of waste. However, since the measures for final disposal of radioactive waste have become concrete and the receiving facility has started operation, the need for a large volume reduction of waste is no longer essential, and a more stable solidification treatment and stable The need for solidified products is higher.

Therefore, since radioactive wastes, which are generated in small quantities and are of many types, are stored and stored without being solidified, it is desired to develop equipment for efficiently solidifying and processing these many kinds of wastes.

An object of the present invention is to provide a solidification treatment facility for radioactive waste, which has a function of injection solidification and a function of kneading and solidification, which makes it possible to treat many kinds of waste in the same facility. That is.

[0012]

In order to achieve the above object, the present invention provides a solid waste treatment facility for radioactive waste,
A waste filling device that fills a drum with a predetermined amount of waste, and a kneading and solidifying device installed in the latter stage of the waste filling device, wherein the kneading and solidifying device is a waste weighing device, a solidifying material weighing device, Additive water measuring device, kneader into which waste, solidifying material and added water measured by these devices are added,
It has a discharge valve provided at the exit of this kneading machine, has a function of injection and solidification in which a drum can filled with waste by the waste filling device is kneaded and filled with a solidifying material, and a predetermined amount of waste and solidifying material. In addition to having the function of kneading and solidifying for kneading and filling in a drum can, the discharge valve can be adjusted so that the opening is small during the injection solidification and the opening is large during the kneading solidification.

In the above solidification treatment facility, preferably,
The kneading and solidifying device stores a first solidifying material silo containing a solidifying material for injection solidification and a second solidifying material containing a solidifying material for kneading and solidification.
And a solidifying material silo for supplying solidification material to the solidifying material metering device from the first solidifying material silo during injection solidification, and kneading and solidifying from the second solidifying material silo during kneading and solidification. The solidifying material for use is supplied to the solidifying material measuring device.

Further, preferably, the kneading machine has a kneading tank, a stirring blade installed in the kneading tank, and a driving device for rotating the stirring blade, and the driving device performs the stirring at the time of pouring and solidifying. It is possible to control so that the rotation speed of the blade is increased and the rotation speed of the stirring blade is decreased during kneading and solidification.

In the solidification treatment facility, the waste filling device is a device for filling pellets, for example, as waste into drums. Further, the waste filling device may be a device that fills a drum can with a compact solid waste compacted body as waste, or a device that fills a drum can with a miscellaneous solid waste ingot.

[0016]

As described above, conventionally, the application of a treatment method that is efficient and has a high volume reduction efficiency has been promoted for radioactive waste that is generated in a large amount. On the other hand, the radioactive wastes that are currently stored without being solidified are characterized in that there are many types and the amount thereof is not large. Therefore, it is not realistic to install a dedicated solidification treatment facility for the solidification treatment of these wastes.

It is desired that these waste materials are collectively solidified in the same equipment to form a stable solidified body. The method for solidifying radioactive waste is divided into a kneading and solidifying method and an injection and solidifying method. Further, the kneading and solidifying method includes an in-drum method and an out-drum method. Among the in-drum method and the out-drum method, the out-drum method is superior in kneading property between the waste and the solidified material. Therefore, the out-drum method is used for kneading the waste. This is because when the waste and the solidifying material are kneaded, the filling amount of the waste is increased as much as possible, the viscosity of the kneaded product is increased and the kneading property is deteriorated, so that strong kneading property is required. The kneading in a kneading tank dedicated to kneading is more suitable than the in-drum method of kneading in a drum can.

The injection and solidification method is a method in which the drum can is filled with the waste material in advance and then the solidification material is injected from above to solidify. In the case of this method, a device for preliminarily filling the drum with waste is required. Further, the waste to which the injection solidification can be applied is a pellet waste or a non-combustible miscellaneous solid waste such as a pipe in which the solidifying material can flow down the waste gap.

Various wastes can be solidified by a solidification method (equipment), either injection solidification or kneading solidification. Both the injection solidification and the kneading solidification require kneading with the solidifying material alone or kneading with the solidifying material and the waste, and a kneading machine is required in terms of equipment. However, the kneading machine can have a simple structure because the fluidity of the solidifying material is good when kneading only the solidifying material for injection solidification.
In the case of kneading and solidification, the viscosity of the kneaded product for kneading the solidifying material and the waste is high, and it is necessary to have a structure in which kneading properties and discharge properties of the kneaded product after kneading are improved.

Conventionally, it has been considered that the kneaders for injection solidification and kneading and solidification are designed and used for individual purposes.
Due to the equipment configuration, the kneading machine is shared by the kneading machine for solidifying material for injection and solidification, and the kneading machine for waste and solidifying material for kneading and solidification. By performing the solidification process according to the method that suits the product, it is possible to rationalize the operation of the equipment and the equipment investment.

In the present invention, a kneading and solidifying device is installed in the latter stage of a waste filling device for filling a drum with a predetermined amount of waste, and the kneading and solidifying device has a waste weighing device, a solidifying material weighing device, and an added water weighing device. , A kneading machine into which the waste measured by these devices, the solidifying material and the added water are provided, and the function of the injection solidification to knead and fill the drum can filled with the waste by the waste filling device, With a structure having a function of kneading and solidifying a predetermined amount of waste and a solidifying material and filling the drum in a drum can, various wastes can be solidified by the same equipment.

At this time, it is necessary to change the opening of the discharge valve of the kneading machine for injection solidification and kneading solidification. This is because in the case of injection solidification, the viscosity of the solidification material is low, and since the injection speed must be adjusted according to the inflow speed of the solidification material into the waste gap, the opening of the kneader discharge valve is Because it is necessary to squeeze. That is, in injection solidification, if the opening of the discharge valve is opened too much, the solidified material paste is filled into the drum tube at one time to cover the waste on the upper part of the drum can, and the solidified material is replaced to prevent the discharge of the exhausted air. , The solidifying material is not filled sufficiently. On the other hand, in the case of kneading and solidification,
The viscosity of the kneaded material increases because the filling amount of the waste is increased, and the opening degree of the discharge valve of the kneader needs to be larger than that of the injection solidification.

In the present invention, the discharge valve of the kneading machine can be adjusted so that the opening degree is small at the time of pouring and solidifying and the opening degree is large at the time of kneading and solidifying. The solidifying material paste or the kneaded material is injected at an injection speed. In the case of the injection solidification, the solidifying material paste can be sufficiently filled in every corner of the waste, and in the case of the kneading and solidification, the kneaded material can be quickly filled.

As described above, it is possible to flexibly solidify a large number of kinds of radioactive waste in the same equipment, which reduces the equipment cost and the efficiency of the installation space as compared with the case where a treatment equipment is provided for each waste. Operation becomes possible.

The drum can 1 is filled with a predetermined amount of waste from 10. Next, the drum can 1 is moved to below the kneader 25 by the roller conveyor 5. At this time, the on-off valves 30, 32, 33 are sequentially opened by the control device 4, the solidified material is supplied to the solidified material silo 22 in the solidified material supply line 23, and the added water is added in the added water supply line 24.

Be thrown into.

The solidifying material and the added water charged into the kneading machine 25 are kneaded under predetermined conditions and injected into the drum can 1, and the waste in the drum can is solidified. At this time, the rotation speed of the motor 42 and the opening degree of the discharge valve 34 are controlled by the control device 4 so as to be suitable for the kneading for pouring and solidifying, the rotation speed of the stirring blade 41 is large, and the opening degree of the discharge valve 34 is small.
