[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a radioactive material for drying and pulverizing liquid radioactive waste such as spent ion exchange resin slurry and concentrated waste liquid generated from nuclear facilities such as nuclear power plants.

Nuclear facilities such as nuclear power plants (hereinafter referred to as nuclear facilities)
Liquid radioactive waste, such as slurry and concentrated waste liquid (used ion-exchange resin (hereinafter referred to as waste resin)), has conventionally been subjected to various treatments and management such as cement solidification, asphalt solidification, and tank storage.

ところが、原子力施設の増大、運転実績の長期化に伴い

However, with the increase in the number of nuclear facilities and the lengthening of their operating history, the amount of radioactive waste that accumulates has become a problem, and there is a strong demand for reducing the volume of waste.

In order to meet these demands, we are currently developing dry powdering and granulation that significantly reduces the volume of waste resin slurry and concentrated waste liquid by drying it into powder, and then granulating it to increase the volume reduction effect and stabilize it over the long term. Technology is becoming more practical. In some cases, as an alternative to granulation, a treatment method is being implemented in which powder is mixed and solidified with an assimilated material (such as plastic), which is considered to be sufficient to withstand final disposal.

Figure 3 shows the flow of conventional dry powder processing equipment. In the dry powder processing equipment, low-concentration waste resin slurry generated at the upstream generation source 1 is collected in a sedimentation separation tank 2, and after sedimentation and separation, the supernatant water is sent to a low conductivity liquid waste treatment system 4 by a decant pump 3. The waste resin is transferred as a waste resin slurry with a predetermined concentration to a waste resin receiving tank 6 by a transfer pump 5, and further transferred to a supply tank 8 by a waste resin receiving pump 7 in a predetermined amount at a predetermined concentration. In addition, the concentrated waste liquid generated in the concentrator 9 is
Similarly, a predetermined amount is transferred to the supply tank.

The waste resin slurry or concentrated waste liquid transferred to the supply tank 8 is supplied to the dryer 11 by the supply pump 10, and the moisture is removed to form a dry powder, which is then sent to the downstream equipment 12 where it undergoes granulation, solidification, etc. Processing is done. Dryer 11
The water removed within the tank becomes steam and is led to the condensate system 13, and after being condensed, is sent to the condensate tank 14. Also, dryer 11

This wash water, like the condensed water, is sent to the condensate tank 14. The condensed water and washing water in the condensed water tank 14 are transferred to the high conductivity liquid waste treatment system 17 by the condensed water transfer pump 16. Following the flow of liquid in the drying and pulverization treatment equipment, All of the water that has flowed into the supply tank 8 is transferred to the high conductivity liquid waste treatment system 17 and subjected to concentration treatment again. All the hot water supplied for cleaning will also be transferred to the high conductivity liquid waste treatment system 17 and concentrated again. This is from the perspective of equipment rationalization due to the increased throughput of the high conductivity liquid waste treatment system, that is, the concentrator, which is relatively expensive compared to the low conductivity liquid waste treatment system in terms of equipment costs and operating costs. However, in current dry pulverization equipment, the conductivity of the waste liquid in the condensate tank exceeds the inlet standard of the low conductivity liquid waste treatment system, so the low conductivity Cannot be treated in liquid waste treatment systems.

Moreover, if we pay attention to the solid content flowing into the condensed water tank 14, it is difficult to say that the solid content that flows into the condensed water tank 14 is further dried after passing through the concentrator 9.

The purpose of the present invention is to improve the dry pulverization processing equipment so that it can effectively utilize the generated waste liquid, and as a result, the load on the high conductivity liquid waste treatment system is reduced due to the reduction in the amount of generated waste liquid, and the amount of hot water used for cleaning is reduced. It is an object of the present invention to provide a method for treating radioactive waste that can reduce the load on a hot water system due to a reduction in the amount of water and reduce the amount of solid content circulating in the system.

〔発明の概要〕[Summary of the invention]

本発明は、乾燥粉体化処理の各所における液体状の廃棄

The present invention was achieved by paying attention to the properties and amount of liquid waste generated at various points during the dry pulverization process.

(2) Since the water in the waste resin slurry has low conductivity, it can be treated with a low conductivity liquid waste treatment system. Because the water has been diluted with condensate water generated from the condensate system, its conductivity and solids concentration exceed the acceptance criteria for low conductivity liquid waste treatment systems, but it is not suitable for cleaning water. It fully satisfies the water quality required for water, and even when mixed with separated waste resin and supplied to the dryer,
The amount of increase in solids concentration due to mixing does not significantly affect dryer performance.

(4) Since the waste liquid in the condensed water tank is a mixture of condensed water at about 100°C and washing water at about 60°C, it sufficiently satisfies the water temperature required for hot water for washing.

(5) The amount of waste liquid generated in the condensed water tank is the sum of the amount of water in the waste liquid supplied to the dryer and the amount of hot water supplied for cleaning. When the amount of water is sufficient and is used for both, there is almost no remaining amount and effective reuse can be achieved.
