For many Member States with operating nuclear power plants, it has been some years since a nuclear power plants (NPP) has been commissioned, and most of the staff with experience in commissioning has since retired. Additionally, in a number of Member States, serious consideration is being given to initiating a new nuclear power programme. This publication is intended to provide useful information for both situations. It is expected that Member State organizations will use this information to improve their training programmes and other aspects of human resource management for commissioning of NPPs.
