Paris, France – 11 January 2024newcleo and NAAREA are pleased to announce the creation of a strategic and industrial partnership dedicated to Generation IV (Gen-IV) nuclear energy.

This initiative is designed to meet the specific needs of the Gen-IV reactors currently under development. The aim is to support all players in their industrial, technological, scientific and regulatory development. It is part of a complementary approach to the essential industrial SMR alliance, soon to be launched by the European Commission.

newcleo and NAAREA, the first two winners of the France 2030 call for projects for innovative nuclear reactors, are joining forces to accelerate the development of their technologies – newcleo is developing a lead-cooled fast neutron mini-reactor (30MWe then 200MWe) and NAAREA a molten salt fast neutron micro-generator (40MWe, 80MWth). Whilst different technologies, both Gen-IVsolutions make it possible to use spent fuel from conventional reactors, ensuring complete closure of the fuel cycle. Both newcleo and NAAREA plan to bring their solutions to market by 2030.

This strategic and industrial partnership is intended to be open to all players involved in the industrial design and deployment of Gen-IVfast neutron reactors, in the following cooperation areas:

  1. The fuel cycle: access to spent nuclear fuel (in particular the separation of transuranic elements (plutonium and americium)), and the development and implementation of a supply chain for the reprocessing of spent fuel
  2. Financing fuel cycle infrastructure: through the development of public-private partnerships
  3. Research: the development of a joint research and development platform (heat exchangers, materials, etc.) and the facilitation of funding at European level
  4. Industrial development: by optimising and supporting procedures with the safety and security authorities, providing access to scientific computing tools particularly for safety demonstrations, making test centre sites available for future prototypes (including associated laboratories), and developing and implementing shared test facilities.

This integrated industrial, technological, scientific and regulatory collaboration will enable newcleo and NAAREA, and subsequently other players, to pool their efforts to accelerate innovation in the field of Gen-IVnuclear energy, and also gain in efficiency, while retaining their two technologies and their specific features.

Under this partnership, joint initiatives can be developed with the entire French nuclear ecosystem to facilitate the decision-making needed to successfully complete the energy transition through a mix that includes sustainable and innovative nuclear energy.

Stefano Buono, newcleo Chairman and CEO: “By joining forces, newcleo and NAAREA are further encouraging the development and deployment of Gen-IVnuclear technology in Europe. This collaboration reinforces our shared commitment to innovation and sustainability in the nuclear sector.”

Jean-Luc Alexandre, Chairman and founder of NAAREA: “Through this industrial partnership, NAAREA and newcleo are creating momentum to accelerate their development by providing a joint and coordinated response to the demands of public authorities for a unified voice to express common needs. Our two companies want to simplify the work of public authorities and ultimately promote the development and deployment of Gen-IV nuclear power in Europe, against a backdrop of strong global competition.


NAAREA (Nuclear Abundant Affordable Resourceful Energy for All) was founded in 2020 by Jean-Luc Alexandre and Ivan Gavriloff to help meet the objectives of energy sovereignty, decarbonization and improving the energy mix. NAAREA is developing a groundbreaking energy solution that will completely close the fuel cycle: the XAMR® (eXtrasmall Advanced Modular Reactor), a molten salt fast neutron microreactor capable of producing electricity (40 megawatts electric) and heat (80 megawatts thermal) that will burn plutonium and the most highly radiotoxic waste (with a lifetime of over 100,000 years) produced by nuclear power plants. The XAMR® is designed to be industrially mass-produced and installed in close proximity to consumers, namely in the mobility sector, electro-intensive industries and remote areas. NAAREA benefits from the support of the French Alternative Energies and Atomic Energy Commission (CEA) and French National Centre for Scientific Research (CNRS), as well as industry players such as Assystem, Dassault Systèmes, Orano and Framatome. A carbon-free and nonintermittent energy source planned to be on the market by 2030, the NAAREA XAMR® is opening the way for sustainable and innovative nuclear energy that supports energy independence, increased resilience and the circular economy. NAAREA is a winner of the “Innovative Nuclear Reactors” call for proposals under the France 2030 investment plan and a beneficiary of the French Tech 2030 support programme.
