Update on Canadian Regulatory Oversight of Ageing Management for Nuclear Power Plants

摘要

This paper provides an update on Canadian Nuclear Safety Commission (CNSC) staff perspectives on managing the safety aspects of ageing of structures, systems, and components (SSC) of nuclear power plants (NPP). Managing the safety aspects of NPP ageing requires a proactive, systematic, and integrated ageing management approach for the coordination of all activities relating to the understanding, control, monitoring, and mitigation of ageing degradation of SSC through the lifecycle of a NPP. A CNSC regulatory document on ageing management based on modern international guidelines is described. In addition, the development of CNSC staff review guidelines for New Builds is included. Finally, CNSC participation in a number of ageing-management and structural integrity initiatives with industry and other national regulatory agencies both, within Canada and at international level are presented.
