Aging Management Methods for Nuclear Power Plant Components

The component aging is unavoidable during the service of nuclear power plants and affects the safety, economic benefits and life of nuclear power equipments. The paper introduces the concept of the component aging and the aim of its management. In the meantime, the aging mechanism is analyzed and the management method is introduced in detail. It is very feasible in practice that the pro-maintenance control method is employed preferentially integrating with other maintenance strategies by combining investigation of aging mechanism and status supervision and fault diagnosis.
