WWER机组蒸汽发生器腐蚀损伤剩余寿命评价方法

摘要

Horizontal steam generator is one main equipment of WWER unit. In operation of Steam generator, the life steam generator will be affected because of corrosion. In this paper, one life assessment of WWER steam generator corrosion damage is introduced, based on European Union VERLIFE standard, referenced American ASME standard, British BS7910 standard, etc.%卧式蒸汽发生器是WWER机组一回路重要设备之一，蒸汽发生器(SG)在使用过程中会产生腐蚀，影响到设备使用寿命。在分析欧盟VERLIFE标准基础上，结合美国ASME、英国BS7910等标准，提出WWER机组SG腐蚀损伤寿命评价方法。
