摘　　要：三门核电1号机组作为全球首台AP1000核电机组,其凝结水精处理系统混床出口钠控制指标为小于0.06μg/L,常规的原子吸收光谱法和离子色谱法无法满足其检测要求。因此,改进了原子吸收光谱法和离子色谱法,以提高其检测限,探索合适的凝结水精处理系统混床出口超痕量钠检测方法。Sanmen Nuclear Power Unit 1 is the world’s first AP1000 nuclear power unit. The sodium control index of the mixed bed outlet of the condensate polishing system is <0.06μg/L, and conventional atomic absorption spectrometry and ion chromatography cannot meet its detection requirements. In this paper, atomic absorption spectrometry and ion chromatography were improved to increase their detection limits, and a suitable method for ultra-trace sodium detection at the mixed bed outlet of the condensate polishing system was explored.
