As of 31 December 2022

Brazil has one nuclear power plant at Angra, 200 km west of Rio de Janeiro. The plant has two operating reactors with a combined capacity of 1884 MWe and a third unit under construction.

Following many years of delay, construction of Angra 3 began in 2010 but has been suspended several times. Construction recommenced in November 2022 but was once again stopped in April 2023 following orders from the municipal government of Angra dos Reis.

In December 2022 Indústrias Nucleares do Brasil (INB) signed a contract with Rosatom for the supply of 330 tonnes of uranium in the form of natural uranium hexafluoride to the Angra plant from 2023 to 2027. In May 2023, three contracts were signed with Westinghouse to cover the supply of advanced 16x16 fuel assemblies for Angra 1 reloads and to develop a project for the protective grid component of the fuel assembly, as well as INB supplying staff to move fuel in the USA.
