摘要
某大型放射性废液贮罐内放射性水平较高,运行年限较长已经进入退役阶段。贮罐去污是必要的,可以显著减低人员集体剂量。通过分析比较确定喷淋循环去污最为适合本项目放射性废液贮罐去污,采用真实试样进行试验,研究喷淋去污的试剂配比、关键工艺参数以及去污效果。根据实际工况,从辐射防护最优化以及废物最小化的原则出发,对贮罐喷淋循环去污系统进行方案研究。
The operation life of a large radioactive waste liquid storage tank in a base is long,and had potential safety hazards for the environment,it was in the decommissioning phase.Tank decontamination is necessary,it can significantly reduce the collective radiation dose of personnel.Though analysis and comparison,it was determined that spray cycle decontamination was most suitable for the decontamination of the radioactive waste liquid storage tank of this project.Real samples were used for the experiment to study the reagent ratio,key process parameters and decontamination effect of spray decontamination.According to the actual working conditions,the scheme of the spray cycle decontamination system was studied based on the principles of radiation protection optimization and waste minimization.
