Diamante Energia, Núcleo Brasil Energia — NBepar (a company created in 2024 to structure the Diamante Group's nuclear sector) and Terminus attended the World Nuclear Exhibition (WNE 2025), the world's leading exhibition on civil nuclear energy, held in Paris, France, from September 4 to 6.
At the event, the nuclear microreactor project being developed by Terminus, a subsidiary of Núcleo Brasil Energia ParticiENT, was presented. The microreactor is a compact and modular nuclear reactor designed to generate energy more safely, flexibly and at a lower cost than traditional nuclear power plants.

For the first time, the Brazilian delegation occupied a booth, where it showed projects that are being developed in the country for the peaceful and sustainable use of nuclear energy. Diamante Energia, INB — Nuclear Industries of Brazil, Amazul — Amazônia Azul Defense Technologies S.A. and Atech Negócios em Tecnologia — a company from the Embraer group — were part of the stand -, under the coordination of ABDAN — Brazilian Association for the Development of Nuclear Activities.
The Brazilian delegation held meetings with institutions and visited the booths of companies from various countries.
The project, whose first units with a capacity of 5 MW contained in a sealed 40-foot container are expected to start operating in eight to ten years, will be carried out at the Nuclear Energy Institute (IEN), in Rio de Janeiro, and on the campus of the Federal University of Minas Gerais (UFMG), in Belo Horizonte.
The use of nuclear microreactors for distributed generation of electrical energy and/or for the stabilization of microgrids that have renewable sources of electricity generation, in and of itself, is a technological innovation.
For the first time, a Finep Project will bring together as many (9) scientific, technological and innovation institutions (ICTs) from 3 regions of Brazil (NE, SE and S), for the development of a cutting-edge technology project in the world. The project contemplates the manufacture of new alloys using strategic and abundant materials in Brazil, such as Uranium, Beryllium and Niobium, and the state of the art in additive manufacturing techniques.
In addition, the initiative foresees the development of the supply chain, which will allow the Brazilian MRN to be competitive, and which will promote a great multiplier effect of projects of this nature in universities and industries.
Currently, Brazil has scientific and technological competence, as well as industrial capacity to design, manufacture, and operate mRNs. In addition, the country has a very robust regulatory framework for nuclear licensing of nuclear facilities. To obtain a license from the Nuclear Authority, for new installations, of any size, there are important safety demonstrations, without which such a license cannot be obtained.
During the execution of the project, various experiments and technical reports will be produced, presented and discussed with the Nuclear Authority with the objective of demonstrating the technical viability and safety of mRNs. During the execution of the project, various experiments and technical reports will be produced, presented and discussed with the Nuclear Authority with the objective of demonstrating the technical viability and safety of mRNs.
The Finep Project will carry out studies on the use of mRNs in municipalities with less than 20,000 inhabitants in Brazil. This corresponds to 68% of Brazilian municipalities, totaling about 30 million inhabitants, in order to demonstrate that they are a safe, sustainable option with low socio-environmental impact for a just energy transition.
