The 2004 Indian Ocean tsunami damaged the Madras Atomic Power Station in India and led to a new understanding of the importance of flooding hazards caused by tsunamis at nuclear power plant sites. The Great East Japan Earthquake and subsequent tsunami in 2011, which heavily damaged the Fukushima Daiichi nuclear power plant, re-emphasized the importance of tsunami hazard assessments. Recognizing…
The response of a nuclear installation’s structure during an earthquake depends on the characteristics of the ground motion, the surrounding soil and the structure itself. Soil– structure interaction (SSI) analysis is used to evaluate the effects of seismic ground motion on an installation’s structure, system and components, to ensure it is designed to withstand the effects of earthquakes…
The global nuclear safety and security framework (GNSSF) provides a conceptual structure and guidelines for achieving and maintaining a high level of safety and security at nuclear facilities and in nuclear related activities around the world. Technical and scientific support organizations (TSOs) play an essential role in sustaining the GNSSF by providing assistance to regulatory bodies in esta…
This report contains the 52nd edition of the IAEA’s series of annual reports on operating experience with nuclear power plants in Member States. It is a direct output from the IAEA’s Power Reactor Information System (PRIS) and contains information on electricity production and overall performance of individual plants during 2020. In addition to annual information, the report contains a hist…
The use of simulators for the training and qualification of nuclear power plant (NPP) control room operating personnel has become a standard practice throughout the world to develop and reinforce knowledge of plant systems and their relationships. It is an approach to increase the ability to apply plant procedures, to advance practical skills in operating the plant in normal, abnormal and emerg…
As societies evolve and citizens have increasingly easy access to more information, stakeholder engagement has become recognized as a growing area of strategic value for the development of nuclear programmes. Nuclear science and technology often face unique challenges with regard to public understanding and acceptance. It is generally recognized that nuclear technologies contribute significantl…
This publication describes the practices and challenges related to risk aggregation for various hazards, various operational states, and considering all sources of potential radioactive releases at a nuclear installation site. It provides a methodology and technical basis for risk aggregation and describes the good practices and practical examples of risk aggregation developed by IAEA Member St…
The status of the IAEA safety standards derives from the IAEA’s Statute, which authorizes the IAEA to establish or adopt, in consultation and, where appropriate, in collaboration with the competent organs of the United Nations and with the specialized agencies concerned, standards of safety for protection of health and minimization of danger to life and property, and to provide for their appl…
This is the 41st edition of Reference Data Series No. 2, which presents the most recent reactor data available to the IAEA. It contains summarized information as of the end of 2020 on power reactors operating, under construction and shut down as well as performance data on reactors operating in the IAEA Member States. The information is collected through designated national correspondents in th…
This Safety Requirements publication was prepared under the IAEA programme on Safety Standards for Nuclear Installations. It establishes requirements and provides criteria for ensuring safety in site evaluation for nuclear installations. The Safety Guides on site evaluation listed in the references section provide recommendations on how to meet the requirements established in this Safety Requir…
