  • 摘要: 1993-2014年采集了大亚湾核电基地周围水蒸气、雨水、海水、监测井水、饮用水样品,分析其氚的浓度和大亚湾核电氚的排放情况.结果表明,液态流出物受纳水体(西大亚湾)中能监测到高于本底水平的氚,最大值为70.7 Bq·L-1,年均值范围为0.8-4.4 Bq·L-1,较文献报道的本底值约高一个数量级;核反应堆周围监测井水中能监测到氚,主要来源于气态流出物的排放和水汽交换,随雨水进入监测井,浓度范围-1,均无累积效应.此外核电附近空气水蒸气中氚浓度较环境本底略高,核电周围动植物体内的有机氚及饮用水中3H含量未发现异常.
    Abstract: Tritium discharged by Daya Bay nuclear power plant (NPP) and the concentration in the environment medium nearby such as vapor, rain, sea water, monitoring well water, drinking water since 1993-2014 are reported in this paper. The results showed that the concentration of Tritium in sea water from west Daya Bay is higher than background. The max value is 70.7 Bq·L-1 and the average annual value is in the range of 0.8-4.4 Bq·L-1.The range of Tritium in the monitoring well is -1, which originated from gaseous and liquid effluents of the NPPs, and entered well water together with rainfall, without accumulation effect. And 3H in vapor near NPPs is slightly higher than background. There is no abnormal tritium level in drink water and OBT in propagation near NPPs.
