Research Development of Zinc Water Chemistry in PWRs

Zinc addition in the primary side circuit of pressurized water reactor (PWR) nudear power plants as zinc water chemistry (ZWC) is one of the most effective methods to mitigate the corrosion of structural materials. The general situation of ZWC application to PWR nudear power plants overseas, the effects of ZWC on general corrosion, stress corrosion cracking and oxide films of structural materials, and the existing problems are summarized.
