Construction and Optimization of Nuclear Power Plant's Material Anticorrosion Program Based on Classification Management

The equipment anticorrosion program technology system covering the whole plant based on the theory of classification management was built. Classification management includes the classification of environment and corrosion, the materials classification and corrosion resistance evaluation, the development degree of corrosion and protection work, the organization of equipment anticorrosion program, etc. Practice has proved that the classification management effect is good, in the case of limited resources it is conducive to highlighting the focus of anticorrosion work, it provides reference experience for other nuclear power plants.
