National Nuclear Energy Commission (CNEN)
Brazil’s public nuclear institution connects a fusion research network with planned LFN facilities and a superconducting tokamak concept. Its relationship with INPE remains transitional.

This is a general development-stage reference. This company's or project's precise stage is unconfirmed, so no position is assigned. Development pathways vary by technology and business.
Fusion within a broader nuclear institution
The Comissão Nacional de Energia Nuclear (CNEN) is a public organization associated with Brazil’s Ministry of Science, Technology and Innovation. Created in 1956, it became a federal autonomous agency in 1962. Its responsibilities span research, education and societal applications of nuclear technology; it is neither a fusion-only laboratory nor a reactor startup.[1]
Its June 2026 institutional account also describes the separation associated with creation of the independent nuclear-safety authority ANSN. An outdated organization chart should not be used to assign all present-day nuclear research and regulation to CNEN. This profile focuses on its fusion collaboration and capacity-building role.
A research network and a new tokamak concept
CNEN describes reactivation of a Brazilian fusion network connecting universities, research centers and industry. Training and international cooperation include researchers studying at China’s Southwestern Institute of Physics. National capability requires people able to design, diagnose and interpret experiments—not simply the acquisition of a machine.[2]
The same announcement outlines international collaboration on a conceptual design for a new Brazilian tokamak using high-temperature-superconducting coils and advanced systems. This is a plan, not an operating superconducting reactor or electricity achievement. Selecting superconductors does not resolve magnet stress, cooling, joints, protection or plasma-operation challenges. Domestic industrial participation is a stated direction, not evidence of particular contracts already delivered.
LFN and RMB are different facilities
The planned Laboratório de Fusão Nuclear (LFN) is research infrastructure, not an independent power company. CNEN’s October 2025 account describes design work and a planned location on the RMB site at Iperó. RMB is a multipurpose fission research reactor associated with applications including radioisotopes; sharing a site does not make it the same fusion facility.[3]
The document signed with CNNC Overseas on October 22 was described as a confidentiality agreement concerning RMB, CENTENA and LFN. It should not be recast as a fusion power-plant construction contract. Cooperation frameworks, detailed design, procurement, completion and operation are separate evidentiary stages.
Understanding the transition with INPE
INPE’s cooperation extension covers October 10, 2026 through October 10, 2027. It provides for provisional LFN activities at INPE’s ETE location until permanent Iperó facilities become available. This establishes an institutional connection, not completed relocation. INPE’s spherical-tokamak experience and CNEN’s future research framework should not be double-counted as unrelated companies.[4]
Proposed upgrades and superconducting development indicate an effort to expand domestic capabilities from plasma science to engineering. Progress should be tracked through funding, training, facilities, design-to-test milestones and actual industrial contributions. International policy statements matter, but they do not fix a demonstrated commercial-fusion date.[2]
