摘要: 探讨了国内不同堆型核电站放射性废气处理系统技术使用现状,不同影响因素对活性炭滞留惰性气体性能的影响以及活性炭性能试验验证可行性。结果表明,系统压力越高、温度及气流相对湿度越低,动态吸附系数越大;一定范围的气流比速、炭床长径比与惰性气体、CO2、氟利昂以及甲烷浓度对动态吸附系数的影响可以忽略;可采用活性炭样品动态吸附系数测定法进行系统性能评价。

关键词: 放射性废气处理系统, 惰性气体Kr、Xe, 动态吸附系数

Abstract: The gaseous radioactive waste processing systems in different types of reactor nuclear power plant were investigated. Influencing factors with the activated carbon absorption of noble gases and the feasibility of activated carbon performance test were then discussed. Dynamic absorption coefficient increases with the rise of system pressure and decreases with the rise of temperature and relative humidity. The influence of flow rate in a certain range, ratio of length and diameter, noble gas, CO2, Freon, methane concentration are neglectable. The sampling method may be used in performance test of carbon delay system.

Key words: gaseous radioactive waste processing, noble gases Xe, Kr, dynamic absorption coefficient
