摘　　要：探讨了国内外不同碘吸附器取样技术及使用现状,分析了碘吸附器取样代表性影响因素并进行了验证试验。结果表明:当取样装置中的炭床厚度和经过取样装置的压力降与通过吸附器排架的炭床厚度和压力降相同时,才能保证取出的样品具有代表性。应用本研究结果对本文所设计的两种外部取样装置进行了可行性分析。Sampling technologies of iodine adsorbers in different types of nuclear power plants are investigated and their different influence factors on sample representativeness of the entire adsorbers are analyzed.Results of performance tests under different conditions and adsorbent bed-depths showed that the bed depth and pressure drop through a sampler section are the same as through the main adsorber bank for the sample to be representative,which may be helpful to the feasibility analysis of the external sampling device of iodine adsorbers.
