[en] The management of nuclear power plant projects with delays of several years with respect to the original scheduled commercial operation date presents particular issues and problem areas beyond the normal management tasks needed for projects implemented within originally planned schedules. During the years 1997-1998 the IAEA collected information and practical examples on necessary management actions to preserve the capability for resuming work and completing delayed nuclear power projects when conditions permit. The results were published in the IAEA-TECDOC-1110 entitled Management of Delayed Nuclear Power Plant Projects. As this publication was finalized, at the end of 1998, the available information at the IAEA PRIS (Power Reactor Information System) indicated that more than 40 nuclear power plant projects had delays of five or more years with respect to the originally scheduled operation dates. The PRIS data, collected at the end of 2007, illustrates a trend toward restarting and completing projects that were once delayed. The data indicates that the number of delayed nuclear power projects has reduced to about 25. Some practical methodologies and successful experience from the restarted projects were reviewed, summarized and included in the present publication. The purpose is to address the specific management issues pertaining to a delayed nuclear power project in the period after the decision for restarting is adopted. This publication covers those management issues not considered within the normal processes described in other IAEA publications. It is expected that the practical experience collected from delayed nuclear power projects that were successfully restarted, completed and brought to commercial operation, can provide useful assistance to the management of similar projects considering resumption of work in the future. This publication was produced within the IAEA programme directed to increase the capability of Member States for strengthening national and regional nuclear power infrastructures
