摘　　要：统计分析了田湾核电站1、2号VVER机组自运行以来气态氚和液态氚的排放情况,研究发现氚的排放量和归一化排放量满足国家标准要求;进入18个月燃料循环后,气态氚年排放量无明显变化,液态氚年排放量有所增加;液态途径是田湾核电站1、2号机组氚的主要排放途径,通过液态途径排放的氚占排放总量的90%以上;每个燃料循环周期内,液态氚月度排放量呈周期性的变化,气态氚月度排放量在燃料循环周期内变化并不明显。This article analyzes gaseous tritium discharge and liquid tritium discharge since the operation of TNPS Unit 1&2(VVER).It was found that the tritium discharge and normalized discharge meet the standard's requirements.After the 18-month fuel cycle,the annual emission of gaseous tritium did not change significantly,but the annual discharge of liquid tritium increased.Liquid tritium discharge is the main way at TNPS Unit 1&2,and the proportion of liquid tritium discharge is greater than 90%of total tritium discharge.In each fuel cycle,the monthly discharge of liquid tritium changes periodically,while the monthly emission of gaseous tritium does not change significantly.
