The Team's role is to oversee prompt implementation of the IAEA Action Plan on Nuclear Safety (drawn up in the wake of the Fukushima Daiichi accident) and to ensure proper coordination among all stakeholders.

Division of Nuclear Security (NSNS)

The Division of Nuclear Security is responsible for coordinating and implementing the IAEA's nuclear security programme to protect against, detect and respond to criminal acts or acts of nuclear terrorism and threats thereof. NSNS comprises four Sections:


Nuclear Security of Materials Outside of Regulatory Control Section

The Nuclear Security of Materials outside of Regulatory Control Section is responsible for activities that assist States in establishing and maintaining nuclear security systems and measures for the prevention and detection of, and response to, nuclear and other radioactive material outside of regulatory control. These activities include developing nuclear security guidance that is consistent with the relevant binding and non-binding international legal instruments for dealing with nuclear and other radioactive material outside of regulatory control, as well as providing assistance, upon request, to States in implementing the nuclear security framework. In addition to the development of nuclear security guidance, the Section provides evaluation and assessment services and education and training activities, develops methodologies, and assists in security upgrades relating to nuclear and radioactive material detection and response capabilities. In so doing, the Section organizes a large number of evaluation missions, training courses and workshops and convenes technical meetings for methodology development.

Nuclear Security of Materials and Facilities Section

The Nuclear Security of Materials and Facilities Section is responsible for activities related to establishing and sustaining nuclear security systems for nuclear and other radioactive material in use, storage and during transport, and for associated facilities. These activities include developing nuclear security guidance consistent with relevant binding and non-binding international legal instruments in the area of regulation, assessment, protection, transport, accounting and control of nuclear and other radioactive material and security culture, as well as assisting Member States in implementing the nuclear security framework. The Section provides evaluation and assessment services, such as the International Physical Protection Advisory Service, and education and training, develops methodologies and assists security upgrades relating to nuclear and other radioactive material and associated facilities and transport. The Section also provides assistance to Member States in enhancing regulatory frameworks for nuclear security. In so doing, the Section organizes a large number of evaluation missions, training courses and workshops and convenes technical meetings for methodology development.

Information Management Section

The Information Management Section is responsible for the establishment and maintenance of the mechanisms required to collect, collate and analyse nuclear security related information required for the effective implementation of activities to strengthen the international nuclear security regime. The Section is responsible for maintaining the Incident and Trafficking Database and related information, as well as the system to develop Integrated Nuclear Security Support Plans, and for providing official reports on nuclear security to Member States and to the general public. For this purpose, it liaises with other international organizations and Member States to enhance cooperation in and increase the outreach of nuclear security information. The Section is also responsible for implementing arrangements to maintain the confidentiality of sensitive information.

Programme Development and International Cooperation Section

The Programme Development and International Cooperation Section interacts with donors and provides support to the overall planning and coordination of the work of the Division including the evaluation of results, financial matters, reporting to donors and the assessment of outcomes of programme activities. The Section is also responsible for coordinating the training programme implemented by the other three Sections, evaluating the programme and developing a collaborative network of Nuclear Security Support Centres which underpin the sustainability of nuclear security in Member States.

Division of Nuclear Installation Safety (NSNI)


The Division of Nuclear Installation Safety's objective is to achieve and maintain a high level of safety of nuclear installations worldwide that are under design or construction or in operation by establishing standards of safety for the protection of health, including standards for nuclear power plants and other nuclear installations and facilities, and by providing for the application of these standards through, inter alia, support for the IAEA's Technical Cooperation programme, the rendering of safety review services, the promotion of education and training, the fostering of information exchange and the coordination of research and development. In addition, the Division helps ensure safety at nuclear installations by promulgating international safety instruments such as the Convention on Nuclear Safety and the Code of Conduct on the Safety of Research Reactors. NSNI comprises five sections:


International Seismic Safety Centre (ISSC)

The International Seismic Safety Centre (ISSC) aims to strengthen Member States' capabilities to enhance the safety of nuclear installations through the proper selection of sites, assessment of site specific hazards and the utilization of site parameters in the design of the installation. The ISSC develops and implements safety standards and guides for design and safety assessment, methods and tools for deterministic and probabilistic safety analysis and safety performance evaluation for all external hazards considered in the design of a nuclear facility. The Section coordinates and supports Member States in establishing and implementing the engineering safety of installations and safety assessment and capacity building activities for embarking countries in the area of site and installation design safety, construction and operations.

Operational Safety Section

The Operational Safety Section's main aim is to enhance Member States' capabilities to improve the operational safety of nuclear power plants through operational safety review services, the use of IAEA safety standards and continuous self-assessment. Its activities include assessment of operational safety performance, long-term operation and operating experience; promotion of management for safety and safety culture; and maintaining the international reporting system database for nuclear power plants.

Safety Assessment Section

The Safety Assessment Section (SAS) helps to improve the capability of Member States in carrying out effective safety assessments and enhancing the safety of nuclear installations to achieve a high level of safety by developing safety standards and guides for design and safety assessment; by promoting the use of advanced safety assessment methods and tools with enhanced integration of deterministic and probabilistic approaches and the use of risk informed and performance based safety evaluation approaches.

Regulatory Activities Section

The Regulatory Activities Section's main objective is to help enhance effective regulatory infrastructures for nuclear safety in Member States based on IAEA safety standards and use of self-assessment. The Section's activities include safety review and advisory missions to Member States, the development and revision of safety standards, support for effective regulatory development for countries embarking on new nuclear power programmes, development of training programmes for regulators, and organizational aspects related to the Convention on Nuclear Safety.

Research Reactor Safety Section

The Research Reactor Safety Section (RRS) works with Member States to develop an international research reactor and fuel cycle facility safety enhancement plan and regime. Activities in this area include monitoring research reactors subject to project and supply agreements and assisting Member States possessing such reactors in fulfilling all the relevant safety obligations. The Section also covers a wide range of topics related to research reactor and fuel cycle facility safety, including siting, design, construction, commissioning, operation, utilization and decommissioning.
