PRIS is a comprehensive data source of nuclear power reactors in the world. It includes specification and performance history data of operating reactors as well as reactors under construction and those being decommissioned.
Since 1970, the monthly data on production and power losses have been recorded in PRIS. Recently the electricity production data were complemented by information on energy provided by nuclear power plants to non-electrical applications, such as district heating, process heat supply or desalination. Information about the decommissioning process of shutdown units has been also incorporated into PRIS.
Due to detailed classification of energy losses and comprehensive outage coding system, a set of internationally accepted performance indicators are calculated from the PRIS performance data. The indicators can be used for benchmarking, international comparison or analyses of nuclear power availability and reliability from reactor specific, national or worldwide perspectives. These analyses can be utilized in evaluating the competitive advantages of nuclear power compared with other power sources.
PRIS outputs are available in annual publications, on the public PRIS website, and to registered users through on-line applications.
Nuclear Power Reactors in the World, published since 1981, is one of the most popular annual publication of the IAEA. The publication Operating Experience with Nuclear Power Stations in Member States has been published since 1970; it includes comprehensive information about operational experience of each individual reactor unit.
Registered users have on-line access to PRIS through the web-based applications supporting data collection and performance indicator reporting.
