According to the available information at the IAEA Power Reactor Information System (PRIS) at the end of 1998 there were more than 40 nuclear power plant projects with delays of five or more years with respect to the originally scheduled commercial operation. The degree of conformance with original construction schedules showed large variations due to several issues, including financial, economic and public opinion factors. The PRIS data collected at the end of 2007 illustrated a trend toward restarting and completing projects that were once delayed. The data indicates that number of DNPPs has reduced to about 25.

Taking into account the number of NPP projects with several years delay in their original schedules (DNPPs), the IAEA has being collecting information for development of guidance on necessary management actions to preserve the capability for resuming work and completing DNPPs when conditions permit.
The results have been published in the recent NE Series NP-T-3.4 Restarting delayed nuclear power plant projects (2008). In addition, management Workshops, directed to identify the subject areas where exchange of experience among Member States can be mutually beneficial in identification of problems and successful management of the completion of DNPPs, were organized approximately every two years.
The 5th Workshop on Managing the Completion of Delayed Nuclear Power Plant Projects was held 17–20 March 2008 in Buenos Aires and Atucha II NPP site, organized by IAEA in cooperation with Nucleoeléctrica Argentina S.A. (NA-SA), Argentina. The Workshop was designed for senior managers or representatives, directly responsible for DNPP activities in nuclear utilities, design, technical support and regulatory organizations. A total of 22 participants from 8 countries took part in the Workshop. The main topics regarding DNPPs included: human resources issues, driving factors to resume construction, managerial challenges, experiences and lessons learned. The funds for this activity under Technical Co-operation Project ARG/4/090 were provided by the host country organization NA-SA.
