Cement solidification body, solidification method and solidification system for nuclear power plant radioactive waste treatment
The invention discloses a cement solidification body for nuclear power plant radioactive waste treatment, a solidification method and a solidification system. The cement solidification body is prepared from the following raw materials in parts by weight: 10-20 parts of radioactive waste, 59-73 parts of a dry material, 1-3 parts of a water reducing agent and 15-25 parts of demineralized water. The dry materials comprise 3-5 parts of bentonite, 55-65 parts of cement and 1-3 parts of lime; the curing method comprises the following steps: weighing raw materials, mixing to obtain cement paste, and curing to obtain a cement cured body; the cement solidification system comprises a solidification container, a first filling part, a second filling part, a stirring device and a conveying device used for conveying the solidification container, the first filling part and the second filling part are both arranged above the solidification container and are sequentially arranged in the movement direction of the solidification container, and the stirring device is arranged above the second filling part. The problem that radioactive waste is not uniformly distributed in the cement solidified body is solved, and the wrapping performance of the cement solidified body on radionuclide is enhanced.
本发明公开一种用于核电厂放射性废物处理的水泥固化体、固化方法及固化系统,该水泥固化体由以下重量份数的原料制成:放射性废物10‑20份、干料59‑73份、减水剂1‑3份、除盐水15‑25份;干料包括膨润土3‑5份、水泥55‑65份和石灰1‑3份;固化方法:称取原料并混合得到水泥浆,固化后得到水泥固化体;水泥固化系统包括固化容器、第一填充部、第二填充部、搅拌装置以及用于运输固化容器的输送装置,第一填充部和第二填充部都设置在固化容器的上方,并沿着固化容器的运动方向依次排列,搅拌装置设置在第二填充部的上方。本发明减少放射性废物在水泥固化体中分布不均匀的问题,强化水泥固化体对放射性核素的包裹性。
