摘要: 核电站主回路中腐蚀产物的氧化净化是核电站大修的源项控制中最重要的一环。本文综合分析氧化净化过程中pH值、H₂O₂和溶解氢浓度对主回路活化腐蚀产物迁移的影响,结合大亚湾核电站的实践经验,提出了低pH值、低H₂和集中引入适量氧的控制手段。

Abstract: The oxidation and purification of the primary coolant loop is of great importance in control-ling the dose rate during the outage.In this paper,the effects of pH value,H₂O₂ and H₂ concentration on the migration of activated corrosion products were discussed theoretically.A new method for the shutdown oxy-genation operation,characterized by low pH,low H₂ and introducing oxygen densely at suitable amount,was proposed based on the operation experience of Daya Bay nuclear power station.
