Company

Mitsubishi FBR Systems was established in 2007 as an engineering company focusing on the development and design of Fast Breeder Reactors (FBRs). Operations began in July 2007, and since then we have been leading the development of FBRs in Japan based on the Mitsubishi Group's accumulated experience in nuclear-related business.

Nuclear power, with the increase of renewable energy, can support the stable energy supply as a large scale energy source independent of the weather, as well as contribute to improvement of energy security by reducing dependence on fossil fuel. It is essential for Japan, where energy resources are scarce, to make continuous efforts to secure energy diversity and improve self-sufficiency. In particular, in order to enhance Japan's energy self-sufficiency rate, it is important to be independent both in terms of resources and technology.

If FBR technology is put into practical use, it will be possible to recycle spent fuel from nuclear power plants and use it effectively as an energy resource of the country again, and thereby increasing the energy self-sufficiency with our own technological capabilities.

FBRs can also reduce the volume and toxicity of radioactive waste contained in spent fuel, helping elimination of environmental burden resulting from nuclear power generation.

With the aim of commercializing FBRs, we will continue to promote the development of FBRs in collaboration with Japanese and international partners, thereby contributing to society through stable energy supply and decarbonization and playing a role in achieving the SDGs.

The Five-party Council on Smooth Transition to a Fast Breeder Reactor Cycle Demonstration Process (Ministry of Education, Culture, Sports, Science and Technology, Ministry of Economy, Trade and Industry, Japan Atomic Energy Agency, The Federation of Electric Power Companies of Japan, The Japan Electrical Manufacturers' Association) established a policy (Note) on the research and development framework for sodium-cooled fast breeder reactors (FBRs).

• Responsibilities, authorities and engineering functions will be given to a single core manufacturer so that FBR development activities can be efficiently carried out with a clear chain of responsibility.
• The core manufacturer will establish a FBR development company that collectively implements engineering activities and executes procurement from manufacturers.

• Contribute to social development and a prosperous future for humanity through FBR development.
• Strive for technical development with a global perspective and contribute to securing energy for the next generation and preserving the environment.
• Establish a relationship with society based on trust by ensuring management transparency and proactive information sharing.
