Angra 1 was bought from the American company Westinghouse as a \"turn key\" package, a closed contract that did not provide for technology transfer to Brazilian suppliers.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx) In 1975, Brazil and Germany signed a cooperation agreement to develop a complete nuclear fuel cycle in Brazil, including a protocol for purchasing eight PWR-type plants; the first two 1,300 MW-class units, which became Angra 2 and Angra 3, were ordered that year from Siemens/KWU.[5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf)\n\nThe program was then slowed by Brazil's economic conditions. From 1984 onward, slow economic growth had a serious effect on the nuclear program and on the construction of Angra 2 and Angra 3; the utility continued work on Angra 2 and rock excavation for Angra 3 on annual government budgets until the whole project was stopped in 1986.[5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf)\n\n## Angra 1\n\nAngra 1 is a two-loop Westinghouse pressurized water reactor with 640 MW of gross capacity, 609 MW net, and a nominal thermal power of 1,882 MWt.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx) • [4](https://www.eletronuclear.gov.br/Nossas-Atividades/Paginas/Informacoes-de-Angra-1.aspx) It entered commercial operation in 1985 as Brazil's first nuclear power plant.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx) In its early years the plant had equipment problems that impaired operation; these were resolved in the mid-1990s, after which the unit performed at levels comparable with international practice.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx)\n\n**Life extension.** [Eletronuclear](https://www.edgepedia.org/eletronuclear) submitted a request to renew Angra 1's operating license to the national regulator, the [Comissão Nacional de Energia Nuclear](https://www.edgepedia.org/comissao-nacional-de-energia-nuclear) (CNEN), in 2019, and delivered the third periodic safety review report in December 2023.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx) Preparatory work has included replacing the steam generators, applying a weld overlay to pressurizer nozzles, replacing the reactor pressure vessel head and the main transformers, and programs for obsolescence management and concrete structure inspection.[1](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-1.aspx) In November 2024, CNEN granted the Authorization for Long-Term Operation, permitting Angra 1 to operate until 2044, subject to conditions including a new periodic safety review in 2033.[8](https://www.gov.br/cnen/pt-br/assunto/ultimas-noticias/cnen-autoriza-extensao-da-operacao-de-angra-1-por-mais-20-anos/) The World Nuclear Performance Report states a different end date of 2055 for the same authorization.[10](https://world-nuclear.org/images/articles/World_Nuclear_Performance_Report_2025_ec7e189b.pdf) The Tribunal de Contas da União, Brazil's federal audit court, which reviewed the extension program in 2026, describes the authorization as running to 2044 under Resolução-Cnen 331/2024.[11](https://portal.tcu.gov.br/imprensa/noticias/extensao-da-vida-util-de-angra-1-e-analisada-pelo-tribunal-de-contas-da-uniao)\n\nThe extension program (LTO Angra 1) is scheduled through 2028 at an estimated cost above R$3.5 billion; a TCU audit found a risk that insufficient financing could halt the works, noting that planned long-term funding through R$2.4 billion in convertible debentures had not yet been issued and that bridge loans had already cost more than R$185 million by February 2026.[11](https://portal.tcu.gov.br/imprensa/noticias/extensao-da-vida-util-de-angra-1-e-analisada-pelo-tribunal-de-contas-da-uniao)\n\n## Angra 2\n\nAngra 2 is a four-loop pressurized water reactor of German Siemens/KWU design, with 1,350 MW gross, 1,280 MW net, and 3,771 MWt of thermal power.[3](https://www.eletronuclear.gov.br/Nossas-Atividades/Paginas/Informacoes-de-Angra-2.aspx) • [5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf) Reactor building base-plate concrete was poured on 14 September 1981, and a foundation recalculation during 1976 construction analysis had already caused a severe delay, with foundations completed only in 1982.[3](https://www.eletronuclear.gov.br/Nossas-Atividades/Paginas/Informacoes-de-Angra-2.aspx) • [5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf) After the 1986 stoppage, mechanical, electrical, and instrumentation erection restarted in March 1996; systems needed for core loading were ready in March 2000, and Angra 2 was declared operational in December 2000, with commercial operation from 2001.[5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf)\n\nUnlike the Angra 1 turnkey purchase, the Angra 2 and 3 contract was accompanied by technology transfer to Brazil, which the operator credits with giving the country command of practically all stages of nuclear fuel fabrication.[12](https://www.eletronuclear.gov.br/Seguranca/Paginas/Tecnologia.aspx) In 2025 Angra 2 set its own generation record, and in March 2026 it was reconnected to the national grid after a scheduled outage that began on 16 January.[13](https://www.eletronuclear.gov.br/Imprensa-e-Midias/Paginas/Relat%C3%B3rio-Anual-2025-destaca-contribui%C3%A7%C3%A3o-da-Eletronuclear-para-a-seguran%C3%A7a-energ%C3%A9tica-do-Brasil.aspx) • [14](https://economia.uol.com.br/noticias/reuters/2026/03/13/usina-nuclear-angra-2-volta-a-operar-apos-parada-em-janeiro-diz-eletronuclear.htm)\n\n## Angra 3\n\nAngra 3 is a PRE-KONVOI pressurized water reactor, a sister design to Angra 2, with 1,405 MW gross and 1,340 MW net capacity, and a thermal capacity of 3,900 MWt.[6](https://world-nuclear.org/nuclear-reactor-database/details/Angra-3) Its construction license was issued in June 2010 and first concrete for the reactor building was poured on 1 June 2010, with commercial operation then scheduled for December 2015.[5](https://nucleus.iaea.org/sites/connect/MSNpublic/Pages/nct/downloads/Pub1537_web.pdf) The World Nuclear Association lists the construction start as 30 May 2010.[6](https://world-nuclear.org/nuclear-reactor-database/details/Angra-3)\n\nThe project has been interrupted repeatedly. Work was suspended in 2015 over a financing review and a corruption probe, a 2022 attempt to revive it faltered, and construction was halted again in April 2023.[7](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-3.aspx) • [15](https://www.investing.com/news/economy-news/brazils-government-split-over-multibillion-dollar-nuclear-plant-completion-3873731) • [16](https://www.sfen.org/app/uploads/2025/10/Review-report-Sfen-2026.pdf) Eletronuclear reports about 65 percent physical completion, with roughly R$7.8 billion invested and about R$20 billion then estimated to finish.[7](https://www3.eletronuclear.gov.br/Nossas-Atividades/Paginas/Angra-3.aspx) Its 2025 annual report put progress at 68.84 percent against a planned 78.77 percent and rated the project \"at risk\" after the National Energy Policy Council (CNPE) again failed to decide the plant's fate in December 2025.[17](https://www.eletronuclear.gov.br/Quem-Somos/Governanca/Documents/Relatorios-Anuais/Eletronuclear_RA_2025_Port_Final.pdf)\n\n**The completion decision.** Under Law 14,120/2021, the sale price of Angra 3's energy is to result from a study by the Brazilian development bank BNDES, approved by the CNPE.[18](https://www.sec.gov/Archives/edgar/data/1439124/000129281425002105/ebr20250514_6k1.htm) BNDES modeling delivered in September 2024 put the proposed tariff at R$653.31/MWh (October 2023 basis) and found the costs of finishing and abandoning the project nearly equal, at R$23 billion and R$21 billion respectively.[19](https://www.eletronuclear.gov.br/Imprensa-e-Midias/Paginas/Angra-3%2C-atualiza%C3%A7%C3%B5es-sobre-o-futuro-da-energia-nuclear-no-Brasil.aspx) An updated November 2025 study raised the tariff range to R$778.86 to R$817.27/MWh, pushed completion to 2033, and estimated R$23.9 billion to complete versus R$21.9 to 25.97 billion to abandon.[9](https://economia.uol.com.br/noticias/reuters/2025/11/05/estudo-do-bndes-sobre-angra-3-aponta-custo-maior-da-energia-e-mais-r239-bi-para-conclusao.htm) While the CNPE deliberates, Eletronuclear spends about R$1 billion per year maintaining the project, including R$800 million in debt service to BNDES and [Caixa Econômica Federal](https://www.edgepedia.org/caixa-economica-federal).[9](https://economia.uol.com.br/noticias/reuters/2025/11/05/estudo-do-bndes-sobre-angra-3-aponta-custo-maior-da-energia-e-mais-r239-bi-para-conclusao.htm)\n\nThe Brazilian government itself is divided: Reuters reported in February 2025 that the economic team favored abandoning the project while the Mines and Energy Ministry supported completion, and in February 2026 Minister Esther Dweck said a decision was expected within the semester, noting that the cost of not continuing was very close to the cost of continuing.[15](https://www.investing.com/news/economy-news/brazils-government-split-over-multibillion-dollar-nuclear-plant-completion-3873731) • [20](https://economia.uol.com.br/noticias/reuters/2026/02/12/ministra-dweck-preve-decisao-sobre-angra-3-neste-semestre-e-indica-vantagem-em-concluir-obra.htm) In July 2026 the CNPE recognized the public interest in Eletronuclear's request to BNDES and Caixa for a temporary suspension of Angra 3 debt payments, while stating that the act did not alter financing contracts or determine any suspension.[21](https://www.gov.br/mme/pt-br/assuntos/conselhos-e-comites/cnpe/comunicacoes/cnpe-reconhece-interesse-publico-da-suspensao-do-pagamento-das-dividas-de-angra-3)\n\n## Role in the Brazilian electricity system\n\nThe two operating units together generate about 15 million MWh per year, enough for roughly 6 million inhabitants, and account for about 3% of the electricity generated in Brazil and about 40% of consumption in Rio de Janeiro state; with Angra 3 completed, the complex would supply the equivalent of about 70% of the state's consumption.[2](https://www.eletronuclear.gov.br/Imprensa-e-Midias/Paginas/Eletronuclear-completa-27-anos.aspx) The IEA's 2025 review of Brazil puts the two plants' share of generation at 2% in 2024 and their combined installed capacity at 1,990 MW.[22](https://www.gov.br/mme/pt-br/assuntos/secretarias/sntep/dte/cgate/acoplare/brazil2025-energypolicyreview-iea.pdf) Because the plants run independently of weather, they serve as a stable complement to Brazil's hydro-dominated system, particularly during droughts.[22](https://www.gov.br/mme/pt-br/assuntos/secretarias/sntep/dte/cgate/acoplare/brazil2025-energypolicyreview-iea.pdf) • [2](https://www.eletronuclear.gov.br/Imprensa-e-Midias/Paginas/Eletronuclear-completa-27-anos.aspx)\n\nThe site also hosts research infrastructure: the Neutrinos Angra experiment, a detector for electron antineutrinos, was commissioned at the Angra dos Reis power plant to monitor the reactor's antineutrino emission.[23](https://arxiv.org/abs/1812.11604)\n\n## Safety oversight\n\nCNEN regulates the site and publishes annual operational status reports (RESOU) for the CNAAA units, and CNEN resident inspectors work at the plant around the clock.[24](https://www.gov.br/cnen/pt-br/assunto/radioprotecao-e-seguranca-nuclear/area-nuclear/2024/2024) • [25](https://www.gov.br/cnen/pt-br/assunto/ultimas-noticias/nota-de-esclarecimento-com-monitoramento-rigoroso-e-total-transparencia-cnen-garante-a-seguranca-operacional-da-usina-de-angra-2) The plant has been reviewed repeatedly by international missions: an IAEA Operational Safety Review Team visited Angra 1 from 30 June to 17 July 2003, the 119th mission of the OSART program, and found managers committed to improving operational safety while recommending better long-term staffing and reduced reliance on contractors.[26](https://www.iaea.org/sites/default/files/documents/review-missions/mission_to_angra1_jun_2003_119_.pdf) In December 2024, CNEN publicly addressed an internal leak in the first seal of the Angra 2 reactor vessel head, stating that the leak had remained stable, did not compromise the plant's safety criteria, and that a similar occurrence had been recorded and managed in 2010.[25](https://www.gov.br/cnen/pt-br/assunto/ultimas-noticias/nota-de-esclarecimento-com-monitoramento-rigoroso-e-total-transparencia-cnen-garante-a-seguranca-operacional-da-usina-de-angra-2)\n\n## References\n\n1.
