Abstract
The development process and latest development of preventive corrosion protection management for nuclear power plant equipment are introduced. Due to the significant increase of corrective maintenance activities caused by corrosion failure, the equipment preventive anti-corrosion programme for in-service operating units was first started and implemented in Daya Bay and other nuclear power plants, and a corresponding anti-corrosion management system was established. In domestic new nuclear power plants, this methodology has been accepted and gradually extended to the construction stage of nuclear power engineering units. And in the process of implementation and optimization of preventive anti-corrosion programme, a management system covering the anti-corrosion classification of the whole plant materials with the preventive anti-corrosion programme as the center was established. A number of preventive corrosion management technical standards were formed. The problems that should be noticed in the establishment of preventive corrosion protection management system are analyzed from two aspects as follows, the correlation between corrosion protection programme and other programmes, and the application of corrosion inspection results of equipment to the implementation of anti-corrosion projects.
