The IAEA's Advanced Reactors Information System (ARIS) is a web-accessible database that provides Members States with balanced, comprehensive and up-to-date information about advanced nuclear plant designs and concepts.

Member States, both those considering their first nuclear power plant and those with an existing nuclear power programme, are interested in having ready access to the most up-to-date information about all available nuclear power plant designs, as well as important development trends. ARIS was developed to meet this need. It includes reactors of all sizes and all reactor types, from evolutionary nuclear plant designs for near term deployment, to innovative reactor concepts still under development.

Resource Information

Quality Level	Authoritative: the content is provided by reactor vendors and designers and is reviewed by the IAEA to address technical inquiries and remove any overly promotional material. Each design description is uploaded to ARIS only after the design organization has clarified technical queries and approved the IAEA's revisions
Completeness	Selective: Information is provided voluntarily by reactor vendors and designers and may not cover all designs
Update Frequency	Occasionally
Last Resource Update	September 2024
Subject	Nuclear Power; Nuclear Power Technology; Nuclear Power Infrastructure; Reactor Technology Assessment
