Abstract

Large areas of radioactively contaminated soil can result from releases during nuclear power plant accidents or decommissioning, requiring rapid decontamination. This study evaluated a management option for secondary waste generated after soil washing using a flocculant (J-AF). Fine soil was used to prepare simulated Cs-contaminated soil, followed by roll-compaction pelletization and polymer solidification. Long-term leaching behavior was evaluated for disposal suitability. The leachability indices for Co, Cs, and Sr were 17.76, 17.38, and 14.04, respectively, satisfying the Korean waste acceptance criteria. The results demonstrate the disposal applicability of pelletized polymer waste forms for fine contaminated soil.

聚合物固化洗土后碳污染土壤淋滤特性研究

核电站事故或退役期间释放的放射性物质可能导致大面积的放射性污染土壤，需要快速清除污染。本研究评估了使用絮凝剂（J-AF）洗涤土壤后产生的二次废物的管理方案。采用细土制备模拟cs污染土壤，然后进行滚压造粒和聚合物固化。对长期浸出行为进行了处置适宜性评价。Co、Cs、Sr的浸出度指数分别为17.76、17.38、14.04，符合韩国废弃物验收标准。结果表明，颗粒化聚合物废弃物处理细粒污染土壤具有一定的适用性。
