摘要
目的 建立一套核电站废树脂清洁解控监测流程,满足解控要求并简化监测工作.方法 依据我国现行的法律法规、标准相关要求和核电站运行过程中产生的轻微污染废树脂运行实践,为准确监测待解控废树脂的放射性核素活度水平,针对取样方法、样品均匀性和代表性检验、放射性监测内容与方法及监测简化流程等进行较深入的探讨.结果 建立一套流程完成核电站废树脂的清洁解控监测,解控了满足要求的55桶废树脂.结论 良好的清洁解控流程实现树脂取样的代表性,提高监测数据的准确性,既能区分放射性废物和解控废物,同时可简化监测流程,为今后的废树脂解控工作提供依据和参考.
Abstract
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.
