Abstract

The efficiency of separate trapping of cesium oxide and molecular iodine formed during oxidative thermolysis of cesium iodide in the process of chemisorption on ceramic highly porous block-cellular contact elements is investigated. The dynamic sorption capacity of contact elements with an applied aluminosilicate sorption-active layer and with an active layer of silver nitrate for cesium and iodine, respectively, is determined. The developed contact elements are recommended for use in systems of local gas purification of high-temperature processing stages of recycling of spent nuclear fuel.

氧化环境中陶瓷块状细胞接触元件上碘化铯蒸汽的定位

摘要研究了碘化铯氧化热解过程中形成的氧化铯和碘分子在陶瓷高多孔块状细胞接触元件上的化学吸附过程中的分离捕获效率。测定了分别带有硅酸铝吸附活性层和硝酸银活性层的接触元件对铯和碘的动态吸附能力。建议将所开发的接触元件用于乏核燃料再循环高温处理阶段的局部气体净化系统。
