放射性焚烧灰水泥固化工艺探究

随着我国放射性废物焚烧技术的不断成熟和广泛应用,焚烧灰的处理问题日益凸显。焚烧灰物理状态为细小颗粒物或粉末,具有弥散性,无法直接处置,因缺乏妥善的处理手段,目前多处于暂存状态,积存量逐年增加。焚烧灰在收集、运输、接收及暂存过程中一旦发生泄漏,极易弥散导致严重污染,存在明显的安全隐患。因此,焚烧灰稳定化处理问题急需解决。基于此现状,该文对焚烧灰理化性质进行试验,并对放射性焚烧灰水泥固化技术进行初步探究。

With the continuous maturation and extensive application of radioactive waste incineration technology,the problem of incineration ash becomes more and more obvious.The physical state of incineration ash is fine particulate matter or powder,which has dispersion and cannot be directly disposed.Due to the lack of proper treatment means,most of the ash is in temporary state at present,and the stock is increasing year by year.Once the incineration ash leaks in the process of collection,transportation,reception and temporary storage,it is easy to disperse and cause serious pollution,and there are obvious hidden dangers.Therefore,the problem of incineration ash stabilization treatment urgently needs to be solved.Based on this situation,this paper tests the physical and chemical properties of incineration ash and makes a preliminary study on the cement curing technology of radioactive incineration ash.
