Global Nuclear Safety Assessment Network (G-SAN)

The IAEA is establishing a Global Nuclear Safety Assessment Network (G-SAN) to link experts worldwide and to facilitate focused collaboration on safety assessment capacity building in support of global nuclear safety harmonization especially in the expanding and developing nuclear programmes worldwide.

The G-SAN framework and platforms will be used to:

  • Support Member States in safety assessment knowledge management and capacity building
  • Share among Member States safety assessment experience including analytical and experimental information
  • Collaborate on validation and improvement of safety assessment methods.

The G-SAN Network concept

IAEA Global Safety Assessment Network

The network will be based on the existing experience and products of the IAEA Centre for Advanced Safety Assessment Tools (CASAT). The G-SAN will maintain a central database that includes repository of references, experimental, and other databases, safety assessment tools and collaboration space for work on documents, reviews, etc. In general, access to the network will be reserved for organizations participating in specific projects. However, some elements of the network will be publicly available.

Access the G-SAN Electronic Platform

The G-SAN Advisory Group The G-SAN Advisory Group, consisting of representatives of participating Member States and organizations will review G-SAN programme annually and provide advice on its operation and activities. The operation of the network will rely on voluntary extra budgetary and in-kind contributions of participating Member States.

G-SAN Programme of activities

Capacity Building

G-SAN features and organized activities support development and maintenance of safety assessment capacity as follows:

  • Development of knowledge and skills requirements
    The IAEA Safety Standards at the level of requirements not only identify requirements for safe design, operations or assessment, but as such, define the knowledge needed to assure safety. Therefore, rigorous knowledge and skills requirements, in the form of curricula, developed by IAEA, will be available through G-SAN to all Member States as the Safety Assessment Education and Training Programme (SAET).
  • Training activities and e-Learning methods
    The SAET forms the basis for any IAEA safety assessment related training activities. Training materials (for self-study or instructor training) based on these curricula will be posted on G-SAN. The curricula shall be reviewed bi-annually by an advisory committee of experts representing regulators, the industry and academia to assure that state-of-the-art knowledge is identified and that adequate learning requirements are defined. The modern G-SAN training tools will include the use of analytical simulators and e-learning methods that reduce the burden on organizations seeking training programmes.
  • Safety assessment exercises and skills applications
    Conduct of safety assessment exercises (deterministic and probabilistic). These exercises would consist of methods assessment against experimental data and evaluation of uncertainties.

Collaboration, networking, knowledge management and sharing

  • Technical directories
    The safety assessment knowledge and information will be organized in convenient technical directories through which access to data bases on the G-SAN or links to other relevant networks and databases will be provided.
  • Data hub and technical referencing
    Databases supporting safety assessments such as component and system reliability, experimental data . This system will contain also results of exercises discussed above, and other technical references necessary for validation and conduct of safety analysis methods.
  • Nuclear facilities information
    In support of broader safety activities of the G-SAN, the knowledge management system will also store technical information on nuclear facilities (this information will be maintained at the individual nods of participating Member States) and provide links to other databases such as NE nuclear power plant database.
  • Analytical tools and safety issues
    The knowledge network will maintain information on safety issues, as well as analytical tools and approaches. Several analytical tools are currently available at IAEA to be used within the knowledge network in support of training and other IAEA activities and new collaborative agreements are in preparation with some Member States willing to support Agency’s efforts in raising safety assessment competency worldwide.

Support to G-SAN from Member States: Knowledge sharing

Certain IAEA Member State institutes, TSOs and Agencies possess the technical and didactic know how to facilitate the G-SAN initiative and will share their knowledge with a wider group of members. For example, advanced safety assessment tools have been contributed to the IAEA by the Republic of Korea and the USA for conduct of safety assessment exercises via the CASAT. Other IAEA Member States have offered to provide safety assessment tools, IT support and defined interfaces for construction of a global network. A series of collaborative international exercises are being developed for launch of G-SAN activities.
