摘要/Abstract

摘要： 在不同温度下对模拟浓缩液进行桶内干燥试验,以研究该干燥方法处理核电站产生的放射性浓缩液尾气中核素的活度浓度及分布。结果表明,107 ℃(沸腾状态)干燥,Sr、Cs、Co的载带率为5.14%、0.06,0.05%,且大部分在洗涤液中;90 ℃(非沸腾状态)干燥,Sr、Cs、Co的载带率分别为2.38%、0.03%、0.02%。

Abstract: In-drum drying treatment of simulatedconcentrates was conducted at variable temperatures to identify the activity concentrations and distribution of nuclides loaded in offgas during treatment of radioactive waste generated from a NPP. The result has shown that there exist detectable contents of Sr, Cs, and Co in concentrated liquid and washing liquid, with growing decreased activity concentrations with decreased drying temperatures.The loading ratios of Sr, Cs, and Co are respectively 5.14%, 0.06% and 0.05% under the boiling condition, mostly in washing liquid, whereas 2.38%, 0.03% and 0.02% respectively under non-boiling condition.

Key words: Nuclides loading, In-drum drying, Radioactive liquid concentrates
