The CNSC has recognized that the current level of ageing management effort may need to be further augmented in order to ensure plant safety as Canadian NPPs continue to age. This will require strengthening the role of proactive ageing management utilizing a systematic ageing management process.

As a result, the CNSC has undertaken the development of a regulatory standard on fundamental aspects of NPP maintenance programmes, which emphasizes the important role of proactive maintenance strategies. In addition, the CNSC has commenced the development of a regulatory document outlining the key components of ageing management programmes, recognizing that these are often integrated with economic factors into an overall PLiM strategy.
