It is generally recognized that long term development of nuclear power as a part of the world's future energy mix will require fast reactor technology with closed fuel cycle. The fast neutron spectrum allows fast reactors to increase the energy yield from natural uranium by a factor of sixty to seventy compared to thermal reactors, granting therefore realization of nuclear power programmes for thousands of years, as well as a significant improvement of nuclear waste management. It is for these reasons that fast reactors have been under development for decades in several countries, primarily as breeders and, in recent years, also as High-Level Waste burners.

The necessary condition for successful deployment in the near and mid-term is the understanding and assessment of technological and design options, based on both past knowledge and experience, as well as on scientific and technological research efforts.

With regard to the first, the design and operation of several sodium-cooled fast reactors, such as the Fast Flux Test Facility (FFTF) in USA, the small size Prototype Fast Reactor in the United Kingdom, the prototype Phénix in France, the BN-350 in Kazakhstan, the demonstration plant BN-600 in Russia, Monju in Japan, the commercial size Superphénix in France, etc. have provided an operational experience base of about 400 reactor-years. In addition, there is a considerable base of experience with lead-bismuth (eutectic) cooled propulsion (submarine) reactors operated in Russia.

Examples of current sodium-cooled fast reactors are the China Experimental Fast Reactor (CEFR), which has been connected to the grid in July 2011, the Russian BN-800 and the Prototype Fast Breeder Reactor (PFBR) in India, both under construction.

Besides current fast reactors construction projects, several countries are engaged in intense research and development programmes for the development of fast reactors innovative (GENIV) concepts. In order to establish multilateral international cooperative frameworks to carry out R&D in support to the next generation nuclear reactors, the following initiatives have been launched:

  • the Generation IV International forum (GIF)
  • the IAEA - International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO)
  • European Sustainable Nuclear Industrial Initiative (ESNII)

Areas of interest for international collaboration are identified by Member States through participation in the IAEA Nuclear Energy Department's Technical Working Group on Fast Reactors (TWG-FR). The TWG-FR consists in a group of experts to provide advice and support programme implementation, reflecting a global network of excellence and expertise in the area of advanced technologies and R&D for fast reactors and sub-critical hybrid .
