为使化学泡沫去污工艺达到后处理厂工程应用水平 ,进行了酸性泡沫对后处理厂模拟样品的去污实验研究。结果表明 ,在室温条件下 ,酸性草酸泡沫对模拟污染样品的去污效果较好 ,不锈钢去污系数为 8. 87～ 14 . 34,漆钢为 6 . 5 7～ 8. 40 ;酸性硫酸高铈泡沫对模拟污染样品有很好的去污效果 ,不锈钢去污系数为 12 . 39～ 2 4. 0 8,漆钢为 3. 6 2～ 5 . 14。这两种酸性泡沫适合对后处理厂大体积、复杂形状和多锈的放射性污染设备、设施去污 ,为进一步的中试扩大实验提供了数据支持
In order to make the chemical foam decontamination process reach the post-treatment plant engineering application level, the decontamination experiment of the acid foam on the simulated sample of the post-treatment plant was carried out. The results showed that the acidic oxalic acid foam had better decontamination effect on simulated contaminated samples at room temperature, the decontamination coefficient of stainless steel was 8.77 ~ 14.34, the lacquered steel was 6.57 ~ 8.40, the acidity of sulfuric acid was high The CE foam has a good decontamination effect on simulated contaminated samples. The decontamination coefficient of stainless steel is 12.39-2.480, and the lacquered steel is 3.62-5.5. These two acidic foams are suitable for the decontamination of large-scale, complex-shaped and multi-rust radioactive contamination facilities and facilities in the reprocessing plant, which provide data support for further pilot scale expansion experiments
