Systems and methods for processing radioactive resins

Abstract

The invention discloses a radioactive resin treatment system. The radioactive resin treatment system comprises two temporary resin storage boxes, a conveying device, a stirring device, a waste resin package container and a filling and dewatering device; the two temporary resin storage boxes are used for respectively temporarily storing low-radioactivity resin and medium-radioactivity resin which are flushed into the two temporary resin storage boxes; the conveying device is used for mixing the low-radioactivity resin and the medium-radioactivity resin which are finished storing temporarily, and is also used for conveying the low-radioactivity resin and the medium-radioactivity resin to the waste resin package container; the stirring device is used for stirring the low-radioactivity resin and the medium-radioactivity resin which are temporarily stored in the two temporary resin storage boxes; the waste resin package container is used for accommodating the stirred low-radioactivity resin and medium-radioactivity resin; the filling and dewatering device is used for filling the waste resin package container with a stirred resin mixture, and dewatering the resin mixture in the waste resin package container. Compared with the prior art, the radioactive resin treatment system disclosed by the invention realizes reliable treatment of resin, can effectively package the radioactive resin, meet the requirement on waste package, reduce the size of a waste package, and reduce the waste treatment cost. The invention also discloses a radioactive resin treatment method.

Description

technical field [0001] The invention belongs to the technical field of processing low and medium radioactive waste, and more specifically, the invention relates to a radioactive resin processing system and method. Background technique [0002] Nuclear power plants need to replace the ion exchange bed resin regularly, because it is radioactive, it is a solid waste with medium and low radioactive levels. Such waste requires effective treatment and conditioning to meet waste handling and disposal reception requirements. [0003] At present, there are several methods for treating low- and medium-level resins: one is to send waste resin to an incinerator for pyrolysis and incineration. However, the secondary solid waste produced by pyrolysis and incineration has a high radioactive level and produces more acid gases, which requires high corrosion resistance for subsequent treatment and equipment; the second method is to use cement solidification to receive waste resin in steel dr...

AI Technical Summary

Problems solved by technology

However, the secondary solid waste generated by pyrolysis and incineration has a high radioactivity level and produces more acid gases, which requires high corrosion resistance for subsequent treatment and equipment; the second method is to use cement solidification to receive waste resin in steel drums And pour in cement slurry, and seal and temporarily store the mixed waste after it solidifies

The disadvantage of this method is that the waste package is large in size, which is not conducive to the minimization of radioactive waste; the resin cement solidified body is easy to absorb water and swell, and the external packaging container has high airtightness and disposal environment requirements.
