The statute of the IAEA authorizes the IAEA to "
establish or adopt (...)
standards of safety for the protection of health and the minimization of danger to life and
property". However, it provides no basis for the IAEA to impose legally binding standards to
its member-states, except where the IAEA itself provides materials, facilities or services. The
primary responsibility for regulating the uses of nuclear power has traditionally rested with
national authorities.
The IAEA has developed voluntary Codes of Practice for nuclear power plants relating to, among
others, safety in design, safety in siting and safety in operation. After the accident in
Chernobyl, the codes were revised and a new set was approved by the IAEA in June 1988. They,
however, remain voluntary and address only the safety of nuclear power plants and not other types
of nuclear installations.
In 1991 the German government proposed to turn the voluntary codes into binding international
safety requirements. After several negotiations it was agreed upon in 1994 that the Nuclear Safety
Convention would be a single instrument with its text based on rather general undertakings. The
convention entered into force in October 1996 and still applies only to land-based civil nuclear
power plants.
The convention does not set out mandatory safety standards for reactors nor does it contain
provisions for sanctions in the event of a party failing to meet its obligations. It aims to commit
participating states to achieve and maintain a high level of nuclear safety by setting
international "benchmarks" to which states should subscribe.
