Objective To establishment a process of monitoring waste resin clearance in nuclear power plants,and to meet clearance requirements and simplify the monitoring work.Methods In accordance with the requirements specified in cur-rent laws,regulations,and standards in China,as well as the practice of slightly polluted waste resins generated during the operation of nuclear power plants,in-depth discussion was conducted on sampling methods,sample uniformity and repres-entativeness tests,radiation monitoring contents and methods,and simplified monitoring processes,in order to accurately monitor the radionuclide activity of waste resins to be cleared.Results A process was established to monitor waste resin clearance in nuclear power plants.A total of 55 barrels of waste resins were cleared and the radiation levels met the require-ments.Conclusion An effective clearance process can facilitate the sampling of representative resins,improve the accur-acy of monitoring data,differentiate radioactive waste from cleared waste,and simplify the monitoring process.Our results provide a basis and reference for future waste resin clearance.
