The International Atomic Energy Agency (IAEA) General Safety Requirements (GSR) series represents the cornerstone of the international nuclear safety regime. These publications establish a globally harmonised set of fundamental safety principles, requirements, and guides for protecting people and the environment from harmful effects of ionising radiation. They are developed through an extensive consultation process involving Member States' experts, ensuring their applicability and acceptance worldwide.
The primary purpose of the IAEA Safety Standards, including the GSR series, is to provide a unified basis for national regulatory frameworks and operational practices in nuclear safety. They aim to foster a high level of safety globally by:
This standardisation helps in promoting a consistent approach to safety culture and practices across different countries, facilitating international co-operation and peer reviews.
The IAEA Safety Standards are organised into a hierarchical structure, with the GSR series forming the highest level of general requirements applicable across all facilities and activities. This structure comprises:
These publications set out the fundamental safety requirements that must be met in all circumstances for all facilities and activities, regardless of their nature or scale. Key examples include:
SSR publications provide more detailed, facility-specific requirements for particular types of installations, such as nuclear power plants (e.g., SSR-2/1 for power plants), research reactors, fuel cycle facilities, and radioactive waste management facilities. These elaborate on how the general requirements apply to specific complex systems.
Safety Guides offer recommendations and explanations on how to comply with the safety requirements. They provide practical guidance on how to apply the principles and requirements in specific situations, covering a wide range of topics from emergency preparedness and response to the safe transport of radioactive material.
The IAEA GSR series is widely used by national regulatory bodies as a basis for developing their own legislation and regulations. Operators of nuclear facilities, designers, and safety professionals also utilise these standards to ensure the safe design, construction, operation, and decommissioning of facilities. Adherence to these international standards is a critical component of demonstrating a commitment to nuclear safety and contributing to global efforts in preventing nuclear accidents and protecting public health and the environment.
