核电厂排放的85Kr的分析方法及剂量评估

摘要/Abstract

摘要： 分析了⁸⁵ Kr的性质及其在环境中的迁移行为,对气态流出物和环境介质中⁸⁵Kr的测量方法进行了总结。研究表明,对核电厂气态流出物和空气、水样品中的⁸⁵Kr,需要经分离纯化进行样品制备,并在液闪谱仪上测量,以获得足够低的探测限。对⁸⁵Kr的剂量评估方法进行了研究,采用目前我国主流机型CPR1000、AP1000和华龙一号的排放源项进行估算,表明核电厂释放的⁸⁵Kr对公众造成的辐射剂量极小。

Abstract: In this paper, the characteristics and environmental behavior of ⁸⁵Kr released from NPP are presented. The analytical methods for ⁸⁵Kr in gaseous effluents from NPP and in environmental samples (including air and water) are also investigated and summarized. Our research indicated that the most effective analytical method for ⁸⁵Kr in effluents and in low-level air and water is Liquid Scintillation Spectrometer (LSC) with a series of separation and purification procedures. Meanwhile, the atmospheric dispersion factors of ⁸⁵Kr were studied using typical release source terms for the CPR1000, AP1000, and Hualong One reactor types. The results indicated that the exposure dose to the public would be extremely small.
