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.

Key words: nuclear power plant, 85Kr, analysis, dose assessment
