Early years (1930–60) In Brazil, theoretical research in the field of nuclear energy began at the
University of São Paulo (USP) in the late 1930s. The following decade, Brazil became a supplier of mineral resources (
monazite, thorium and uranium) to nuclear experimentation projects in the United States, such as the Manhattan Project. In 1947, Álvaro Alberto, a Navy official and a vocal supporter of nuclear power, wrote the first Brazilian nuclear policy plan to be approved by Brazil's national security council, the Conselho de Segurança Nacional (CSN). Implementation of the plan began in 1951, with the establishment of Brazil's national research council, the
Conselho Nacional de Pesquisas (CNPq), and the nomination of Alberto as its president. The institution's general purpose was to promote technological and scientific research in all areas of knowledge and CNPq had specific responsibilities related to the development of nuclear energy; such as promoting research on relevant mineral resources and undertaking the necessary measures to boost the industrialization of nuclear energy. The path toward developing a Brazilian nuclear sector included the nationalization of nuclear activities and specific compensations for exporting strategic raw materials. CNPq sought to acquire nuclear technology from the U.S. and other countries. Washington, however, rejected Alberto's request to purchase a cyclotron from General Electric, which would have allowed Brazil to conduct advanced nuclear physics experiments. Alberto also started negotiations for the acquisition of ultracentrifuges from West Germany. By the mid-1950s Brazil's nuclear program had purchased 3 West German centrifuges for US$80,000. Although the centrifuges arrived in Brazil in 1956, they only became operational in the 1970s. A Parliamentary Commission of Inquiry (Comissão Parlamentar de Inquérito – CPI) established in 1956 uncovered the illegal exports of atomic materials to the United States. It also revealed that Juarez Távora, chief of the military cabinet in the early stages of the
Café Filho administration in 1954, acted in accordance with U.S. requests and adopted a new nuclear policy plan whereby the U.S. was considered the privileged partner of Brazil in the nuclear field. After the investigation was completed, the CPI argued in favor of a more nationalist approach to nuclear policy, resuming the plans advocated by Alberto and the CNPq. It also cancelled all the contracts related to atomic minerals exports. In 1957 Brazil obtained its first research reactor from the U.S. under the "
Atoms for Peace" program. IEA-R1, as it became known when it reached the Institute of Atomic Energy (Instituto de Energia Atômica – IEA) in
São Paulo, was the first reactor ever to operate in the southern hemisphere. In the aftermath of the
1964 coup d’état that ousted the popularly elected government, the ruling military devised a nuclear policy based on the purchase of nuclear power plants in order to generate electricity but also create the conditions for an indigenous nuclear industrial complex inside Brazil. In the long term, stated the plan, Brazil would seek to acquire all the technologies necessary to master the nuclear fuel production cycle. With regard to international standards mandating a limit to
peaceful nuclear explosions (PNE), the military's nuclear policy affirmed that renouncing the right of independent fabrication of PNEs represented "a price too high to pay", since :"1. the draft of the global Treaty does not represent a commitment toward disarmament for nuclear weapon countries; :2.
France and
China do not participate in the negotiations; :3. there are great perspectives in the use of nuclear explosives in mining, opening of ports, canals, and earthmoving, as has been demonstrated by U.S. experiences of the Plowshare program; :4. the knowledge of the technique leading to the construction of nuclear explosives, since subject to the international account and limited to specific objectives of economic development, neither constitutes proliferation nor is necessarily stimulated." Accordingly, in a CSN meeting, President
Artur da Costa e Silva voiced arguments in favor of "doing research, mining and building devices that can explode" and added: "We will not call them bombs, we will call them devices that can explode. Two years later, the parliamentary commission completed its work and concluded that the Brazilian booming industrial growth meant a rising demand of electricity in the country, which confirmed the necessity of nuclear energy. Also in 1968, the government issued a secret "National Strategic Concept" arguing that the acquisition of nuclear science and technology was a means to overcome Brazil's peripheral position in world affairs. According to this perspective, Brazil could not accept the
Nuclear Non-Proliferation Treaty (NPT), an international accord perceived by Brazil as an instrument to curtail the national development of nuclear energy in non-nuclear weapon countries, which did not solve the problem of nuclear weapons. After a large economic growth, Brazil invited different companies and consortiums to present projects for the construction of its first nuclear power plant. After receiving five different proposals, Brazil chose the one made by U.S.-based Westinghouse Electric Company involving pressurized water reactors (PWR). Simultaneously, Brazil started conversations with West Germany and a nuclear cooperation agreement was established between Brasília and Bonn. While CNEN was finalizing the details of the contract with Westinghouse between May 1971 and April 1972, the
United States Atomic Energy Commission (USAEC) approved the supply of nuclear fuel for Brazil's first nuclear power plant, Angra 1. The contract between CNEN and Westinghouse was signed in April 1972 and the construction of Angra 1 began.
1973–78 The military continued to push for development in the nuclear sector. The government attempted to acquire all phases of the nuclear cycle through international cooperation. In 1974, the Brazilian Company for Nuclear Technology (Companhia Brasileira de Tecnologia Nuclear – CBTN) became the Brazilian Nuclear Enterprises (Nuclebrás). Headed by Paulo Nogueira Batista, a career diplomat, Nuclebrás was charged with implementing the nuclear program by promoting the creation of indigenous companies to build parts and offer services for the nuclear plants on the pipeline. While Nuclebrás dealt with implementation and funding, CNEN retained the responsibilities of nuclear planning, regulation and inspection. Additionally, CNEN continued to be the Ministry of Mines and Energy's advisory body for domestic and international nuclear policy. However, after India tested a nuclear device in 1974, the U.S. slowed down and eventually halted nuclear cooperation with Brazil. Also, in the aftermath of the 1973 energy crisis, USAEC made its provision of fuel to third countries subject to availability. This in turn pushed Brazil to accelerate talks with West Germany and France, eventually signing an agreement with the former on 27 June 1975, that established the transfer of operational know-how regarding reactors. The deal represented the largest
technology transfer agreement ever signed between an industrialized country and an industrializing one. Bonn committed to export four to eight reactors over a span of 15 years. Likewise, West German firms agreed to construct a complete nuclear fuel cycle in Brazil: uranium prospecting and mining; uranium enrichment (using the jet-nozzle process); manufacturing fuel rods; and reprocessing spent fuel rods. For West Germany's nuclear industry, this was the most significant contract ever to be established, at an anticipated value of 10 billion marks (roughly US$4 billion). Also, this was the largest single export order in German history. In the years that followed the announcement, Brazil and West Germany were under strong pressure coming from not just the U.S., but also the
United Kingdom,
Canada, France, and the
Soviet Union—countries which supported a restrictive position on nuclear sales and strongly opposed the export of advanced nuclear technology such as fuel reprocessing plants. Shortly after, President (General)
Ernesto Geisel announced the White Book of Brazilian Nuclear Policy (Livro Branco sobre a política nuclear brasileira). The document, intended to clarify aspects of Brazil's nuclear decisions to the public, affirmed the peaceful nature of the program and justified the nuclear option based on the country's growing energy demand. In cooperation with West Germany, the construction of the Angra 2 reactor began in 1976.
The "autonomous" / "parallel" nuclear program (1978–87) In 1978, amid the nuclear deal with West Germany, the growing restrictions to nuclear technology stipulated by the U.S., and the newly created Nuclear Suppliers Group (NSG), Brazil established a secret nuclear project under the coordination of CNEN and implemented by the Institute of Energy and Nuclear Research (Instituto de Pesquisas Energéticas e Nucleares – IPEN), which had replaced the IEA in São Paulo. The original objective of this project was to develop indigenous technology for the production of uranium hexafluoride (UF6). As this project evolved to comprise an actual program, it encompassed research on all phases of nuclear energy production, the construction of a miniature reactor for naval propulsion, and the development of nuclear explosives. Known as the "Autonomous" or "Parallel" Nuclear Program, it was conducted under tight military control, with each one of the armed forces having dedicated budgets to pursue different methods for uranium enrichment. This parallel military program was conducted concomitantly with the civilian one, the latter managed by Nuclebrás. Unlike the civilian program, the autonomous one was not under safeguards. Different branches of Brazil's armed forces had different tasks in the parallel nuclear program. The Navy, which had the most advanced nuclear center – Aramar, located in Iperó, São Paulo – coordinated two projects. Project Ciclone aimed at the development of uranium enrichment technology through the ultracentrifuge method, while Project Remo sought to create a nuclear reactor for a small naval vessel such as a submarine. The Army coordinated Project Atlântico, which tried to develop natural uranium reactors. The Air Force worked on Project Solimões, which researched laser technology for nuclear and conventional purposes as well as the development of "nuclear explosives for peaceful purposes". In the 1980s, evidence surfaced in the press pointing to the existence of two major shafts in the Air Force base of Serra do Cachimbo, in the northern state of
Pará. These raised suspicions over the Air Force's nuclear activities, as the shafts had been possibly designed as testing sites for nuclear explosives. Personnel in charge of the secret nuclear program tried to obtain access to technology and materials in the nuclear bazaar. In the late 1970s, amid a domestic shortage of oil in Brazil,
Iraq offered to supply oil at a discounted price in exchange for 80 tons of Brazilian uranium. Oral accounts indicate that Brazil accepted the offer and concluded a deal with Iraq. However, it interrupted the uranium export when the
Iran–Iraq War intensified, having provided Iraq with less than a quarter of the quantity agreed. Brazil also reportedly bought highly
enriched uranium from China in the 1980s. In December 1982, then-president of CNEN, Rex Nazaré, headed a mission to China with the objective of purchasing enriched uranium from his Chinese counterparts at the China National Nuclear Corporation. Sources have indicated that, a few years later, Brazilian cylinders of hexafluoride were transported to China containing natural uranium. They returned to Brazil in a container that, supposedly, carried porcelain purchased by the First Lady Dulce Figueiredo during the presidential trip. The material was later stored at the IPEN research facility in São Paulo, where the Brazilian Navy was developing technology for uranium enrichment and reactor construction with the ultimate objective of building a nuclear-propelled submarine. Civilian rule was re-established in the country in 1985, and the administration of President José Sarney publicly revealed two years later that Brazil had achieved uranium enrichment capacity through a secret nuclear program. While Sarney made this announcement, there is no indication that he tried to put an end to the nuclear military activities.
1988–2000 In 1988, Nuclebrás was folded into a newly created institution, the Brazilian Nuclear Industries (Indústrias Nucleares do Brasil – INB), which was linked to the structure of CNEN and responsible for uranium extraction, industrial treatment and processing. In that same year, the Experimental Center of Aramar (Centro Experimental Aramar – CEA), was inaugurated in Iperó, São Paulo. Angra 1, which had its first nuclear chain reaction in 1982 and went into commercial operation in 1985, faced numerous problems. Between 1982 and 1992, operations in Angra were halted 16 times for different reasons. The inefficiency of the plant led to a widespread feeling that the nuclear deal with Westinghouse had been a poor decision. Due to the constant interruptions, the power plant of Angra 1 became known in Brazil as the vagalume, or "firefly". Amid the unfolding political transition post-dictatorship, a new Constitution was drafted in 1987–1988, for which Brazil's nuclear development program became a focal point of debate. The article approved by the Constitutional Assembly declared: "All nuclear activity within the national territory shall only be admitted for peaceful purposes and subject to the approval of the National Congress." While current official discourse often presents this decree as a unilateral guarantee that Brazil will never build nuclear artifacts, at the time of the new Constitution Brazil was still arguing for the legality of peaceful nuclear explosions—and oral history evidence points to the notion that those drafting the constitution sought to incorporate language consistent with such technologies. That same year, a CPI was established to investigate the military's autonomous nuclear program. Among the main findings were details of illicit trade of nuclear material, as well as information about illegal financial operations that had served to keep the secret program going. In its final report, the inquiry commission recommended that the parallel program be dismantled with some of its activities to be integrated into the safeguarded civilian program. It also recommended the establishment of accountability mechanisms to increase the safety and security of the program. The economic crisis that had already affected the development of Brazilian nuclear project in the 1980s continued through the 1990s. Nuclear activities slowed down, the program for developing the nuclear submarine ground to a halt and plans to build two additional nuclear power plants were put on hold. Only in 1994 did the Brazilian government decide to resume construction of Angra 2.
2001–present In 2001 more than two decades after the beginning its construction, the nuclear power plant of Angra 2 started its commercial operations. Brazil was reluctant to grant IAEA inspectors full visual access to its centrifuges, which were hidden by 2-meter (6.6-foot) high panels, as Brazilian authorities argued that a superior centrifuge technology had been developed in the country and it was necessary to protect these industrial secrets. After months of impasse, Brazil agreed to allow increased – but not full – visual access to the centrifuges and other industrial equipment by reducing the size of the panels covering the machinery. As a member of the Ministry of Science and Technology reportedly said at that time, Brazil was lifting the skirt and lowering the top a little, but retaining its secrets. In 2006, the Minister of Science and Technology officially inaugurated the complex, located in
Resende, Rio de Janeiro. A first enrichment cascade started in May 2006 at the Resende facility. A second one was activated in November 2009 and, two years later, a third cascade was made operational. Currently, there are four cascades in operation, which allow INB to enrich approximately 14% of Angra 1's annual uranium needs. The other 85% continues to be enriched overseas, mainly in Canada and Europe. In 2007 Brazil launched the National Energy Plan 2030 (Plano Nacional de Energia 2030 – PNE 2030). This plan states the need to increase the energy production in Brazil and proposes that an additional nuclear energy capacity of 5,345 megawatts (MW) be installed by 2030. In order to make it feasible, the plan supports the completion of Angra 3 – whose construction started in 2010 and it is still underway – and recommends the construction of four nuclear power plants across the country. In 2011, the electricity generated by the nuclear power plants of Angra 1 and Angra 2 represented 2.7% of the national energy output, approximately 14 tWh. While Angra 3 remains under construction and is expected to become operational in 2018, This updated study was expected to come out in 2013, as a PNE2035. However, that did not happen. Presently, the website of EPE states that a PNE 2050 is currently in development. Currently, there is only one active uranium mine in the country, located in Lagoa Real, Caetité, Bahia. The annual production of uranium in the Caetité Complex, which is managed by INB, has varied, with the record being 400 tons of uranium concentrate in 2008. There have been plans of developing mine activities in
Santa Quitéria, Ceará, where the uranium presents itself associated with phosphate. Even though INB has undertaken some steps toward establishing this new mine, the license has not been issued yet. In the end of 2008, President Lula signed an agreement with his French counterpart, Nicolas Sarkozy, which established a partnership between the two countries regarding defense issues. In addition to selling 50
EC-725 Super Cougar helicopters France agreed to work with Brazil to build four conventional submarines and one nuclear propulsion submarine. The US$12 billion agreement, The construction of the nuclear submarine is expected to start in 2016, in the Navy's Manufacturing Unit for Metallic Structures (Unidade de Fabricação de Estruturas Metálicas – Ufem), located in Itaguaí, Rio de Janeiro. The likely date for completion is 2023 and the submarine should to start to operate in 2025. The Brazil-France deal is in accordance with the National Defense Strategy (Estratégia Nacional de Defesa – END) that Brazil also issued in 2008. The END states Brazil's ambition to develop and master nuclear technology and conclude the nuclear propulsion submarine. The most recent White Book of National Defense, issued in 2012, states that a nuclear propulsion submarine would contribute to the protection of commercial routes, keep navigation free, help protect natural resources, and promote technological development in the country. In February 2013, the Brazilian government announced the creation of a new state-owned company, the Blue Amazon Defense Technologies (Amazônia Azul Tecnologias de Defesa – Amazul), whose purpose is to promote, develop and maintain the technology necessary to keep the nuclear activities in Brazil going, including the nuclear reactor for the planned submarine. In May 2013, Redetec, a Brazilian administrative body responsible for managing resources for nuclear innovation, contracted the Argentine company
INVAP to build a multipurpose nuclear reactor in Brazil. The reactor is planned to enter operations in 2018, at the CEA. == Nuclear cooperation with Argentina ==
