摘要: 基于目前国内外核电厂对液态流出物处理的技术,流出物中的除氚和14C外的其他核素经一定的工艺净化后可达到近零排放,但是氚不能被有效处理,因此氚浓度的高低是决定液态流出物能否复用的决定性因素。本文借鉴国内已运行核电厂的实践经验,从液态流出物中氚浓度的高低研究AP1000核电机组液态流出物复用和排放的原则:含氚高的废液处理后排放;含氚低的废液处理后尽可能复用,不平衡的部分进行排放。源项计算结果表明,放射性废液经处理后废水的活度(除氚和14C外)不超过50 Bq/L,可满足排放或复用要求。

Abstract: With respect to current waste treatment technology for NPPs at home and abroad, liquid effluents can be managed by certain processes to reach the state of Near-Zero Emission for nuclides, excludingTritium and 14C, in them. As the processes do not treat Tritium effectively, its concentration is a decisive factor to determine whether or not to reuse liquid effluents. With practical experiences learned from running NPPs in China, the principle of liquid effluent's reuse and release for AP1000 nuclear power units is studied. That is, after treatment, release of liquid effluent with high Tritium content, reuse of liquid effluent with low Tritium content as much as possible, and discharge of the unbalanced parts. Calculations with realistic source terms show that, with a low concentration of Tritium in liquid effluent, the demand for discharge or reuse can be met while the activity of it after treatment does not exceed 50 Bq/L, with exception of Tritium and 14C.
