摘要/Abstract

摘要： 核电厂正常运行工况下,气态流出物中惰性气体监测结果一般均低于探测限。如按标准以探测限的1/2统计,可能会过高统计年排放量。本文通过确定气态流出物中⁸⁵Kr与¹³³Xe活度浓度的关系,当惰性气体源项中半衰期最大的⁸⁵Kr低于探测限时,间接估算其活度浓度,以便能准确地对⁸⁵Kr进行年排放量统计。

关键词: 运行工况, 惰性气体, 排放量, ⁸⁵Kr, ¹³³Xe

Abstract: The inert gas monitoring results are generally lower than the detection limit onnormal operating conditions, if relevant monitoring results lower than the detection limit, half of its emissions by statistical detection limit may overestimated the annual emissions. By determining activity proportional relationship of⁸⁵Kr and ¹³³Xe, when the ⁸⁵Kr of maximumhalf-lifein the inert gas source term was less than the detection limit, its activity concentration can estimate indirectly. Thus the annual emissions statistics of ⁸⁵Kr can obtained more objectively.

Key words: Emissions statistics, Proportional relationship, ⁸⁵Kr, ¹³³Xe
