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。

Abstract: 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.

Key words: TNPS, VVER, tritium, discharge
