压水堆核电厂蒸汽发生器传热管的降质问题

摘要

Degradation of tube of steam generator will affect the integrity of primary loop ,after analysis the degradation model of tube ,and introduction of nondestructive testing technology application for in -serv-ice tube and steam generator tube life estimates ,take the corresponding protective measures per the cause of degradation of the tube ,to ensure safe operation of the tube of the steam .%核电厂蒸汽发生器传热管的降质将影响到核电厂一回路边界的完整性。通过对蒸汽发生器传热管的降质模式进行分析，并对在役传热管无损检测技术应用以及寿命预测的介绍，从而针对产生的传热管降质的原因，采取相应的防护措施，确保蒸汽发生器传热管的安全运行。
