Brazil operable reactors share of generation, under construction, CO2 mitigation

Brazil has two operating reactors with a combined capacity of 1884 MWe at Angra, 200 km west of Rio de Janeiro. Construction on a third unit was halted in April 2023. 

A lifetime extension for Angra 1 was authorized by the National Nuclear Energy Commission in November 2024, permitting operations until 2055. 

In January 2025 Eletronuclear and the Brazilian Society of Nuclear Medicine signed an agreement aimed at producing lutetium-177 at Angra 2. A study by Brazil's National Bank for Economic and
Social Development concluded that the cost of abandoning construction of the part-built Angra 3 nuclear power unit could be about BRL21 billion (USD3.7 billion). By contrast Eletronuclear  stimated the cost of completing the project at around BRL23 billion, of which BRL12 billion had been invested. 

In February 2025 the National Energy Policy Council (CNPE) postponed its decision on resuming construction of unit 3. Also in February, Eletronuclear announced a restructuring plan aimed at improving governance and the economic viability of its nuclear projects, and pushed back its target commissioning date for Angra 3 to 2031.
