GIF Parties and Implementing Agents

DISCLAIMER: The entry into force of the 2025 GIF Framework Agreement on 1st March 2025 brings changes to the GIF membership. The website will be updated in due course to reflect these changes.

The 2025 GIF Framework Agreement (FA) is the international treaty that established the GIF under its current form and that dictates its main principles of governance and goals. Each signatory of the this agreement, or FA Party, can designate one or several Implementing Agents. Those are organisations mandated by the FA Party to ensure the fulfilment of its obligations under the GIF FA and the success of the international R&D cooperation on Gen-IV Nuclear Energy Systems that is the raison d'être of the Generation IV International Forum.

How does a country become part of the Generation IV International Forum?

The Forum is an organization that has a specific goal: the development of concepts for one or more Generation IV systems that can be licensed, constructed, and operated in a manner that will provide a competitively priced and reliable supply of energy to the country or countries where such systems may be deployed, while satisfactorily addressing nuclear safety, waste, proliferation and public perception concerns. Membership of a country to the Forum is decided by its present members (unanimous approval required) on the basis of the prospective country's nuclear program, as well as its capacity to contribute to the development of Gen-IV systems. Members are expected to maintain an appropriate level of active participation in collaborative projects, such as the participation in at least one significant collaborative project.
 

The 2025 GIF Framework Agreement has limited the list of countries invited to sign this Agreement to the list presented above for the first three years following its entry into force (March 2028). After this date new countries might be invited to join GIF upon consensus of the signatories of the 2025 GIF FA.
