Upon request from a Member State, SEED provides an independent peer review, an advisory service or capacity building support on safety aspects of the installation siting, design and safety assessment; its counterpart is the Regulatory Body, but participation of the licensee, the Technical and Scientific Support Organisations (TSOs) and independent consultants is often encouraged.
The SEED service is typically arranged in three phases: Pre, Main and Follow up-SEED. It is conducted by a team of international experts led by senior IAEA experts.
The service outcome is a review report, an advisory report, or training material, issued to the requesting Member State with recommendations and suggestions on the compliance with the IAEA Safety Requirements and Guides.
A periodic publication collects the lessons learnt from the implemented SEED services and makes them available to the community at large.
The SEED service can be integrated with other IAEA services addressing specific types of installations, phases of their life or safety programs, such as the Technical Safety Review (TSR), the Operational Safety Services (OSART) and the Integrated Safety Assessment of Research Reactors (INSARR).
According to the Guidelines for the Preparation and Conduct of SEED Missions, the service consists of the following six modules, among which the requesting Member State can select one or more, depending on its needs.
