Abstract：

The steam generator (SG), serving as the critical junction between the primary and secondary circuits in pressurized water reactor (PWR) nuclear power plants, is subjected to long-term exposure to high-temperature, high-pressure, and multiphase flow corrosive environments. Surface corrosion issues in SGs pose a direct threat to the safety and economic viability of nuclear power stations. This paper reviews the latest research progress on the corrosion mechanisms and protection technologies for SG surfaces. It discusses the environmental factors affecting SGs during storage, transportation, and operation, analyzes the causes of surface corrosion, and points out the specialized protection requirements for SG surfaces. The paper also provides a comprehensive overview of the current development status of coating protection technologies, aiming to serve as a reference for addressing corrosion and protection challenges on steam generator surfaces.

Key words： nuclear power steam generator coating protection technology
