The integrity of many SSEs of nuclear power plant has been maintained by various and continuous maintenance activities (replacement of components, preventive countermeasures for aging issues, etc.) so far. And the utilities have been implemented technical ageing evaluation for SSEs and established the long term maintenance policy for aging management. In this paper, the activities for long term operation and extension of operation period beyond 40 years that have been implemented by the utilities are described including some example of measures for ageing management in actual plants (Takahama unit 1/2, Mihama unit 3).
