Safety Assessment of Nuclear Power Programmes

Enhancing Member State capacity to evaluate reactor safety and conduct comprehensive and complete safety assessments to ensure that the IAEA fundamental safety objectives are met

The mission of the safety assessment team is to support regulators, operators, and technical support organisations of Member States in the development and application of advanced nuclear safety assessment capacity, training, tools and services through:

Specific topical areas and their applications include:

  • Design Basis Accident (DBA)
  • Beyond Design Basis Accident (BDBA)
  • Safety analysis
  • Engineering factors important to safety
  • Accident management
  • Safety performance indicators
  • Risk informed decision-making, and
  • Deterministic and probabilistic safety assessment methods/tools.

Safety assessment support functions include assistance in:

  • The conduct of safety assessments and safety enhancements at nuclear sites
  • Developing and applying advanced deterministic and probabilistic analytical methods/tools
  • Assessing the safety aspects of the design of nuclear sites
  • Integrating the risk informed decision-making process
  • Developing and implementing safety performance indicators to monitor and enhance safety
  • Developing and implementing configuration management and design basis maintenance and
  • Establishing and implementing effective safety assessment education and training programmes.

Design Safety for Nuclear Power Programmes

Improving safety assessment and the integrated decision making process

The IAEA helps Member States achieve the optimal level of design and engineering safety for its nuclear installations through:

  • Development of Safety Standards
    To assist Member States in achieving and maintaining a high level of safety in nuclear power plants through the development of safety standards in the design and engineering areas and long term operation, including ageing management, periodic safety review and configuration management
  • Safety Review Services
    To promote and assist Member States in the application of these safety standards through the Design and Safety Assessment Review Service (DSARS), including assistance to improve their ability to perform self-assessments
  • Capacity and Competency Building
    To exchange experience and information on developed methodologies, to build competency through the Safety Assessment Education and Training Programme (SAET), to disseminate good practices and to facilitate knowledge management and networking among the Member States in the technical areas of design and engineering safety, developing and maintaining the related global knowledge base.

The main fields of activity relate to the development and maintenance of Safety Standards for the design of nuclear power plants and for the safety assessment of nuclear installations. SAS also supports Member States in the application of the Safety Standards by providing training and by carrying out the Design and Safety Assessment Review Service (DSARS).

Integrated Risk Informed Decision Making (IRIDM)


Improving safety assessment and the integrated decision making process

Both deterministic and probabilistic analyses contribute to reactor safety by providing insights, perspective, comprehension and balance. Accordingly, the integration of deterministic and probabilistic analyses is increasing to support design, safety evaluation and operations.

Deterministic and probabilistic analyses yield outputs that are complementary to each other. There is a need to use a structured framework for consideration of deterministic and probabilistic techniques and findings. In this process, it is appropriate to create a balance between deterministic approaches, probabilistic analyses and other factors (e.g. engineering factors, good practices, operating experience, management procedures) in order to achieve an integrated decision making process that serves in an optimal fashion to ensure nuclear reactor safety.

IRIDM depends on the integration of a wide variety of information, insights and perspectives, as well as the commitment of designers, operators and regulatory authorities to use risk information in their decisions. The INSAG 25 report focuses on key IRIDM aspects, as well considerations in their application which should be taken into account in order to arrive at sound risk informed decisions.
