    Notice No. 135/79 from the General Secretariat of the Brazilian National Security Council

    In 1978 the National Security Council identified the most important shortcoming of nuclear cooperation with Germany: the non-transfer of technology for the production of uranium hexafluoride (UF6). The lack of this crucial phase for the production of nuclear fuel led Brazil to decide to develop this method by national means, in view of the unwillingness of France and Great Britain to export said technology without a full scope of safeguards. The document reports how the government decided to create an autonomous nuclear project with regard to cooperation with Germany and free from the international safeguards regime. Coordinated by CNEN and implemented by the Institute of Energy and Nuclear Research (IPEN), this project represented the first phase of the “parallel” nuclear program whose objective was the autonomous mastery of the nuclear cycle.

    Memorandum, Minister Saraiva Guerreiro, Information for the President of Brazil, 'Brazil-PRC. Nuclear Energy'

    Memo from Foreign Minister Saraiva Guerreiro to President João Batista Figueiredo on the current state of, and potential for the future of nuclear cooperation with China, in the follow-up to the presidential visit to Beijing. Guerreiro recalls that, since China was also not a party to the NPT, nuclear cooperation and purchase of material, like the uranium acquired in 1982, would not be subjected to full-scope safeguards, preserving the “sovereignty of Brazil’s nuclear program.” Guerreiro mentions a study by the National Security Council, the Nuclear Commission, Nuclebrás and the Foreign Ministry on the commercial and technological potential for an agreement with China, similar to the ones that Brazil had already signed with “other developing countries, namely those that are not members of the NPT.” One such agreement, Guerreiro suggests, could be signed during President Figueiredo’s upcoming visit to Beijing.
