This edition is the thirty-seventh report in the IAEA’s series of annual reports on operating experience with nuclear power stations in Member States. The first publication was issued in 1970. It is a direct output from the IAEA’s Power Reactor Information System (PRIS). It contains information on electricity production and overall performance of individual plants during 2005. In addition to annual information, the report contains a historical summary of performance during the lifetime of individual plants and figures illustrating worldwide performance of the nuclear industry. This is the first such report issued in an electronic version on CD-ROM which provides enhanced features for data search and analysis.
