中放废液大体积浇注水泥固化工程屏障技术

Engineering Barriers Technology of ILLW Cement Bulk Grouting

为探讨中放废液大体积浇注各覆盖层的种类和作用,重点介绍了素混凝土浇注的工艺流程及其屏蔽效果。为了确保大体积浇注水泥固化体长期贮存的安全,待固化体温度降至30℃以下时,需对大体积浇注水泥固化体表面、搅拌槽及搅拌槽间、操作间进行素混凝土浇注,浇注结果表明,素混凝土层能较好地实现屏蔽效果,中放废液大体积浇注水泥固化浇注场址辐射防护水平可得到有效控制。

Classification and function of ILLW cement bulk grouting coverings were discussed, process flow of pain concrete grouting and shielding efficiency were mainly introduced. In order to ensure the ILLW cement bulk grouting coverings safety, while curing temperature fell to below 30 %, the pain concrete grouting result showed that pain concrete grouting can reach shielding efficiency in a better way, radioactivity protection of ILLW cement bulk grouting site was controlled effectively.
