The European Sustainable Nuclear Industrial Initiative (ESNII) addresses the need for demonstration of Generation IV Fast Neutron Reactor technologies, together with supporting research infrastructures, fuel facilities and R&D work.

ESNII’s main goal is to design, license, construct, commission and put into operation before 2025 the Sodium Fast Reactor Prototype reactor called ASTRID and the flexible fast spectrum irradiation facility MYRRHA. The ALFRED demonstrator for Lead-cooled Fast Reactor, and ALLEGRO for Gas-cooled Fast Reactor technologies are also part of the roadmap.


ESNII has a two-level governance:

  • The Coordination Board, which is a restricted executive body representating the four ESNII technologies (sodium-cooled, lead-cooled, lead-bismuth, gas-cooled) taking decisions on the ESNII Strategy, on labels to be provided, etc.

The Task Force brings together technology developers, utilities, engineering companies and research institutions, and represents all members.
