ALLEGRO is an experimental fast reactor cooled with Helium being developed by the European V4G4 Consortium “V4G4 Centre of Excellence” of the nuclear research organizations of the Czech Republic, Hungary, Poland and Slovakia associated with CEA, France. Development of ALLEGRO is an important step on the way to the Gas-cooled Fast Reactor, one of the six concepts selected by the Generation IV International Forum and one of the three fast reactors supported by the European Sustainable Nuclear Energy Technology Platform.

The main purposes of ALLEGRO is the development of:

  • GFR refractory fuels (UPuC SiC-SifC cladding)
  • Helium related technologies (components, instrumentation, purification,…)
  • Safety technical issues and corresponding safety approach framework.
