    • Abstract
  • Tianwan NPP condenser water chambers made of authentic stainless steel and titanium, some iron anodes which used to protect condenser falling off. Metallography, electron microscopy and X-ray diffraction were used to analyze the reasons of individual anode falling off failure. The results indicated that the sensitization of the SS304 core is the main reason, which lead to serious stress corrosion. Some improvement means are made.
