| Abstract: | Dry ice decontamination technology has attracted more and more attendion in the decontamination practice of nuclear facilities due to its high decontamination efficiency,less damage to the substrate and less secondary waste.Because of more decontamination times of reactor refueling system in nuclear power plant,through the analysis of decontamination requirements of reactor cavity and spent fuel shipping shielded cask,a set of dry ice decontamination device is designed to achieve effective decontamination of nuclear facilities,and meet the requirements of personnel operation and transportation.The decontamination process and final secondary waste production also follow the principle of waste minimization which is an important development direction of radioactive decontamination in the future due to its environmental protection and high efficiency. |
