| 摘 要： | 采用APEX放电型准分子激光器作为激光光源,用低放废液制备不锈钢放射性模拟样片,在激光去污装置上开展激光去污工艺参数的研究。通过考察不同的辐照强度、脉冲频率、辐照角度及扫描速率参数对不锈钢放射性模拟样片表面去污因子DF的影响,获得了激光去污工艺参数。在此参数下对模拟样片表面的去污因子大于200,剥离厚度小于20μm。

| Abstract: | The study on the laser decontamination parameters was carried on with the simulated radioactive specimens made by LLRW and using APEX laser.The efficiency of different laser parameters such as laser intensity,laser frequency,laser angle and laser scanning speed were investigated on the decontamination factor(DF),and then the optimized laser decontamination parameters were obtained.Using the optimized parameters,the laser decontamination was studied with the simulated stainless steel specimens by the laser decontamination equipment.The experimental results show that the DF is more than 200,and the peeling thickness on the stainless steel base is less than 20 μm. |
