摘要: 对田湾核电站2号机组压力容器开盖期间气态流出物释放导致电站周边环境γ剂量率的变化从实测值和理论计算值进行比较分析。分析结果表明,实测值和理论计算值基本上是吻合的;同时验证了核电站正常运行期间排放的气态流出物对于环境γ剂量率的影响基本在天然本底波动范围之内。即使在低风速的情况下,气态流出物对于环境γ剂量率的影响也主要在下风向,随距离的增加迅速减小;对于上风向和侧风向的影响则小的多。

关键词: 田湾核电站, 环境, γ剂量率

Abstract: This article analyzes and compares the measured γ dose rate values and theoretical calculated γ dose rate values caused by airborne effluence during pressure vessel uncovered at Tianwan nuclear power station, and the results shows that the measured values and the calculated values are largely consistent.Meanwhile, it is verified that the influence to environmental γ dose rate due to airborne effluent is basically at the range of natural background during the normal operation of nuclear power station.The influence mainly locates in the direction of downwind,rapidly reducing with the distance increasing, and the influence of other directions is relativelyless.

Key words: Tianwan nuclear power station, environment, γ dose rate
