Abstract: Optimization of primary water chemistry is one of the most effective ways to minimize radiation field, mitigate material degradation and maintain fuel performance in pressurized water reactor (PWR) nuclear power plants. It improves characteristics of oxide scales formed on the materials of equipment due to interactions between water chemistry and materials. This article reviews the current status and related problems of the relationship between water chemistry of primary coolant and material degradation in PWR nuclear power plants. Fundamental research progress achieved in recent years on Zn-injected water
chemistry (ZWC) into primary coolants of PWR is introduced.

Key words: high temperature and high pressure water, pressurized water reactor (PWR) nuclear power plants, water chemistry, Zn injection
