蒸汽发生器二次侧系统腐蚀产物沉积促使蒸汽发生器本身进一步腐蚀。导致传热管损坏,热交换能力降低,从而降低功率。大约20—30%的腐蚀产物是长期停堆期间生成的,产生腐蚀产物的主要来源是氧的侵入。
Steam generator secondary side of the system corrosion product deposition prompted the steam generator itself to further corrosion. Resulting in damage to the heat transfer tube, heat exchange capacity is reduced, thereby reducing power. About 20-30% of the corrosion products are generated during long-term shutdown and the main source of corrosion products is oxygen intrusion.
