Method for solidifying cement by mixing radioactive incineration ash and radioactive concentrated solution
The invention belongs to the technical field of radioactive waste treatment, and particularly relates to a radioactive incineration ash and radioactive concentrated solution mixed cement solidification method which comprises the following steps that S1, quantitative radioactive incineration ash is weighed and added into a solidification container, and the solidification container containing the incineration ash is transferred to a cement solidification system; s2, weighing a certain amount of the radioactive concentrated solution, adding the radioactive concentrated solution into a curing container, starting a stirring paddle of the cement curing system, gradually extending the stirring paddle into the curing container, and continuously stirring until the first time after the stirring paddle is in place; s3, weighing a certain amount of an additive, adding the additive into the curing container, and continuously stirring for a second time; and S4, weighing a certain amount of cement dry powder, adding the cement dry powder into the curing container, and continuously stirring for a third time to complete curing. The performance of the solidified body produced by the solidification process and formula meets the requirements of low and medium level radioactive waste solidified body performance requirements-cement solidified body (GB14569.1-2011), and the solidified body can be used for disposal.
本发明属于放射性废物处理技术领域，具体涉及一种放射性焚烧灰和放射性浓缩液混合水泥固化方法，包括如下步骤：步骤S1，称取定量的放射性的焚烧灰加入固化容器中，将装有焚烧灰的固化容器转运至水泥固化系统；步骤S2，称取定量的放射性的浓缩液加入固化容器中，同时启动水泥固化系统的搅拌桨并逐渐将搅拌桨伸入固化容器内，待搅拌桨到位后继续搅拌至第一时间；步骤S3，称取定量的添加剂加入固化容器中，并持续搅拌至第二时间；步骤S4，称取定量的水泥干粉加入固化容器中，并持续搅拌至第三时间，固化完成。本发明固化工艺和配方产生的固化体性能满足《低、中水平放射性废物固化体性能要求‑水泥固化体》(GB14569.1‑2011)的要求，可以用于处置。
