  • IAEA - International Atomic Energy Agency

    The IAEA was founded in 1957 and is connected with the United Nations by various treaties. Its mandate is to promote the safe, secure and peaceful use of nuclear technologies. The use of atomic energy worldwide is not perceived to be critical. The IAEA is the monitoring organization for the compliance with the Non-Proliferation Treaty and is mandated to check on the ground whether the nuclear programmes pursued in all signatory countries are exclusively peaceful in nature. The annual Nuclear Safety Review publishes the global state-of-art of all nuclear power stations that are operating, pausing, shut down, planned or being decommissioned and their current status. The database PRIS (Power Reactor Information System) was used as a source for the number of reactors that supply electricity; the database RRDB (Research Reactor Data Base) has been used as a source for the number of research reactors. Both are databases set up by the IAEA.
