Discussion on Corrosion and Protection Measures Under Insulation Layer of Chilled Water System in Nuclear Power Plants
The chilled water system of the nuclear power plant is equipped with insulation layers,Corrosion under insulation layer(CUI)is prone to occur during the system operation.The occurrence of CUI is influenced by factors such as insulation structure,operating conditions,insulation materials,and coatings.This article discussed the technical and management measures that can be taken to alleviate the occurrence of CUI.This article introduces the selectable detection methods for different stages of CUI and compares the advantages and disadvantages of different detection methods.
