AI Technical Summary

Problems solved by technology

With the development of the atomic energy industry and the widespread use of radioactive isotopes, radioactive waste is increasing day by day. If it is discharged without treatment or improper treatment, the environment will be polluted by radioactivity, which will not only affect the growth of animals and plants, deteriorate water bodies, and endanger human health. even have adverse effects on future generations

[0003] Under the circumstance that the treatment and disposal of radioactive waste is becoming more and more prominent, the traditional waste resin cement solidification process technology will greatly increase the final waste price and increase the capacity, which does not meet the minimization principle of nuclear power waste treatment. At present, Germany, France, the United States and other countries have already A radioactive waste drying device has been developed and has been applied in some nuclear power plants. In addition, according to the retrieval, Chinese patent CN 103453739B discloses a waste resin drying device and drying method, but the device does not have the ability to continuously process waste resin
