Background Information

The revision to SSR-2/2 (Rev. 1) is to be undertaken within the context of the Medium-Term Plan for the safety standards - in accordance with the approach set out in SPESS A of reviewing the safety standards every five years.

Since 2011, there have been additional significant safety enhancements in the commissioning and operation of nuclear power plants – which go beyond the amendments made in response to the findings from the Fukushima Daiichi accident, and which are not currently captured within SSR-2/2 (Rev. 1).

The main justifications for the proposed revision are the following:

  • SSR-2/2 (Rev. 1) does not adequately cover areas such as: corporate governance and monitoring, independent oversight, risk management, knowledge management, defence in depth during operation, performance improvements, preparations for pandemic situations, control of core cooling and fuel storage cooling.
  • Several IAEA General Safety Requirements publications have been published since 2011 and it is necessary to harmonize SSR-2/2 (Rev. 1) with them, namely GSR Part 2 on Leadership and Management for Safety, GSR Part 3 on Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards, and GSR Part 7 on Preparedness and Response for a Nuclear or Radiological Emergency.
  • Additional insights and inputs have been gained through the development of international consensus on topics addressed in several recently issued Safety Guides, namely SSG-48 on Ageing Management and Development of a Programme for Long Term Operation for Nuclear Installations, SSG-50 on Operating Experience Feedback for Nuclear Installations, and SSG-54 on Accident Management Programmes for Nuclear Power Plants, as well as several closely related Safety Guides on operation of nuclear power plants which are expected to be published in 2022.
  • Organizations such as WANO have updated their Performance Objectives and Criteria in 2013 and 2019. Inputs from WANO and other like-minded organizations should also be taken into account to make sure that the Safety Requirements publication remains relevant to the nuclear industry.


Additional inputs to the revision of the SSR-2/2 (Rev. 1) are also expected from Technical Meetings planned to be held in 2022/2023 and from other Agency work such as the project on the assessment of applicability of the IAEA standards on small modular reactors.
