Based on the corrosion issues of component cooling water system (CCWs) in nuclear power plant (NPP), the corrosion inhibition properties and protection mechanism on copper and stainless steel was studied by using tests such as electrochemical method, immersion test and dynamic water simulation. Results show that the optimum inhibitor is the compound of tolyltriazole (TTA) and phosphate, which has an excellent corrosion inhibition efficiency on copper in either pure water or abnormal water. The inhibitor also elevated the pitting potential of stainless steel and contributed to the corrosion resistance.
