某核电站放射性碘废气处理系统活性炭吸附剂测试

Indigenization Research of Activated Carbon Adsorbent for Radioiodine Waste Gas Treatment System at a Nuclear Plant

为实现某核电站放射性碘废气处理系统活性炭吸附剂的国产化,选取国产圆柱状煤质活性炭与椰壳活性炭,以一定比例混合,浸渍烘干,装填到碘废气处理系统中,现场试验结果表明其阻力≤3 400 Pa、除碘效率≥98%,性能满足工程使用要求。

For the purpose of the indigenization of activated carbon adsorbent at a nuclear plant, two types of activated carbons were mixed at the optimum rate, through impregnating and drying. The onsite testing results show that the resistance of the mixed activated carbon is ≤ 3 400 Pa and the efficiency of cleaning radioactive methyl iodine is ≥ 98 %. The other performances meet the needs of engineering.
