Abstract: This paper introduces the background for the ongoing research on accelerated ageing management (AAM) technology for important and susceptible components in Daya Bay nuclear power plant (NPP) and Lingao NPP. The technical procedure, the work architecture and the interfaces with existing operation and maintenance system in NPPs are also detailed. Finally, some representative examples of the use of AAM to solve practical operational issues are presented, before concluding on propositions for the future development of this technology.

Keywords: accelerated ageing; accelerated ageing management; important and susceptible components; maintenance strategies
