The IAEA Power Reactor Information System (PRIS), developed and maintained by the IAEA for over four decades, is a comprehensive database focusing on nuclear power plants worldwide. PRIS contains information on power reactors in operation, under construction, or those being decommissioned. The database covers:
Monthly production and power loss data have been recorded in PRIS since 1970 and are complemented by information on nuclear-power generated energy provided to non-electrical applications such as district heating, process heat supply or desalination. Information relating to the decommissioning process of shutdown units is also available from PRIS.
A set of internationally accepted performance indicators has been developed for calculations with PRIS data. The indicators can be used for benchmarking, international comparison or for analyses of nuclear power availability and reliability according to reactor type, country or worldwide. The analyses can, in turn, be applied to evaluations of nuclear power competitiveness compared to other power sources.
Two official Agency publications are produced each year using PRIS data:
