CORROSION AND PROTECTION DESIGN OF SEA WATER COOLING SYSTEM IN NPP

The function,equipment and typical corrosion events in seawater cooling system of nuclear power plant (NPP) are introduced.Based on typical marine corrosion events,the basic aspects of corrosion preventing design including the design base,material selection,typical corrosion preventing measure,corrosion preventing plan of specific equipment and correlative experience feedback are discussed.The aging,lifetime and corrosion risk of special corrosion preventing system,structure and components are analyzed.The main point of corrosion preventing design of sea water cooling system is summarized,and the importance of the corrosion preventing design in the newly built nuclear power plant project and the applicable and promotional value of the existing outstanding corrosion preventing design proposal are presented when nuclear power enterprise develops fast in our country.
