摘要
压水堆核电站在未发生燃料包壳破损的情况下,85%的堆芯外辐射场是由活化腐蚀产物造成的。本论文分析讨论了一回路冷却剂中主要的活化腐蚀产物及其产生的原理,提出了通过水化学控制来降低活化腐蚀产物的几种主要措施,包括pH控制、氧化运行以及注锌技术等。核电站相关分析数据表明,这些水化学控制措施对于控制活化腐蚀产物均取得了良好的效果。
In the case of PWR fuel cladding without damage,85% of the radiation field outside the core is caused by the activated corrosion products.This paper analyzes and discusses the activated corrosion products in the primary coolant and their causes,and proposes several measures to reduce activated corrosion products through water chemistry control,including pH control,oxidation operation and injection zinc technology.Relevant data analysis shows that the plant,the water chemistry control measures to control the activated corrosion products have achieved good results.
