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 publication presents the results of the INPRO collaborative project: Proliferation Resistance and Safeguardability Assessment (PROSA) Tools. The PROSA assessment process has been developed to specifically address the needs of national self-assessors performing an INPRO Nuclear Energy System Assessment of sustainability. The main objective of this project is to explore approaches to make 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…
This Safety Guide presents the safety principles and the approach underlying the design of nuclear pow er plants and identifies the relationship between the Code of Practice on Design for Safety of Nuclear Power Plants (IAEA Safety Series 50-C-D, hereafter referred to as the Code) and other Guides in the design. area of the NUSS Programme. It should be read as an elaboration of the safety princ…
This publication contains the proceedings of an international conference, held in Vienna, 3–6 September 2001. The topical issues addressed by the conference were: risk informed decision making; influence of external factors on safety; safety of fuel cycle facilities; safety of research reactors; and safety performance indicators. These proceedings contain the topical issue papers, keynote add…
The Country Nuclear Power Profiles (CNPP) publication compiles background information on the status and development of nuclear power programmes across participating International Atomic Energy Agency (IAEA) Member States. The publication summarizes organizational and industrial aspects of nuclear power programmes and provides information about the relevant legislative, regulatory and internatio…
The requirement of deriving design extension conditions (DEC), which are understood to comprise both conditions in events without significant fuel degradation and conditions in events with core melting, were introduced in IAEA Safety Standards Series No. SSR-2/1 (Rev. 1), Safety of Nuclear Power Plants: Design [1]. In SSR-2/1 (Rev. 1) [1], DEC were introduced for the purpose of further improvin…
