en.Wedoany.com Reported - The Brazilian National Nuclear Safety Regulatory Agency (ANSN) officially released new regulations for nuclear power plant site selection on March 30, 2026.

The new regulations introduce a "site pre-licensing" system aligned with international practices and, for the first time, explicitly include small modular reactors and microreactors within the scope of site selection regulation. This provides a clear regulatory framework for the siting of future nuclear power projects, especially the next generation of small and medium-sized reactors.

This revision is a significant update to Brazil's nuclear regulatory system, designed to adapt to global trends in nuclear power technology development, particularly the rise of SMR technology. The new regulations aim to improve the efficiency and predictability of early-stage project work while ensuring safety through standardized site assessment and licensing processes. This regulation is part of a series of recent adjustments to Brazil's nuclear energy policies, reflecting its intent to improve the nuclear regulatory framework and promote the development of nuclear power.

The release of the new regulations provides formal legal basis and operational guidelines for the site selection of Brazil's future new nuclear power projects, including traditional large-scale units and SMRs. By establishing the clear step of "site pre-licensing," it helps investors assess and secure potential sites earlier, reducing uncertainty in the early stages of projects. This creates a more favorable institutional environment for attracting investment and advancing nuclear power plant construction, including the expansion of the existing Angra Nuclear Power Plant and the development of new projects.
