===Fuel cycle domain===

The beginning of the project for the domain of the [[nuclear fuel cycle]] and nuclear reactors took place in 1979, in that year, the military joined the Institute of Energy and Nuclear Research of Sao Paulo where it started to work in the most ambitious military program of Brazil to date.<ref name=”Characteristics 3″/> In 1982, the scientists won its first major victory after adopting the ultracentrifugation technique for enrichment and learning about [[uranium hexafluoride]] technology in the city of [[Poços de Caldas]], [[Minas Gerais]]. In the same year, the project researchers achieved [[Isotopes of uranium|isotopic uranium]] enrichment with centrifuges built entirely in Brazil.<ref name=”naval.com.br”/><ref name=”Characteristics 3″/>

The beginning of the project for the domain of the [[nuclear fuel cycle]] and nuclear reactors took place in 1979, in that year, under the [[Military dictatorship in Brazil|military regime]] with leadrship of the Army general [[Ernesto Geisel]] and lather general [[João Figueiredo]], two enthusiasts of the nuclear technology and nuclear weapons,<ref>{{cite news|title=Documentos apontam corrida nuclear na América Latina durante a ditadura |url=hhttps://oglobo.globo.com/politica/documentos-apontam-corrida-nuclear-na-america-latina-durante-ditadura-11956778|website=O Globo |date=23 March 2014}}</ref> the government joined the Institute of Energy and Nuclear Research of Sao Paulo (IPEN) where it started to work in the most ambitious military program in Brazil‘s history.<ref name=”Characteristics 3″/> In 1982, the scientists won its first major victory after adopting the ultracentrifugation technique for enrichment and learning about [[uranium hexafluoride]] technology in the city of [[Poços de Caldas]], [[Minas Gerais]].

To support the experimental activities of the research and development program of the fuel cycle and nuclear reactors, the Aramar Experimental Center (CEA) was built in the state of [[São Paulo (state)|Sao Paulo]].<ref name=”Characteristics 3″/> The center is home to testing facilities, experimental validation laboratories and some special workshops. It is also responsible for uranium enrichment on a small industrial scale, but sufficient to power existing nuclear research reactors in the country. Over a period of approximately 20 years, the country acquired the full nuclear fuel cycle and was able to begin the construction of the naval nuclear reactor.<ref name=”naval.com.br”/><ref name=”Characteristics 3″/>
