ministry was thinking about what Argentina's reaction should be in case Brazil backed out of ABACC or developed a nuclear weapon. According to the document, one of the responses Argentina was envisaging could be the development and deployment of advanced peaceful nuclear technology, such as a nuclear-powered icebreaker, to demonstrate capacity. ABACC did not comment, but one of its Brazilian officials stated that the information expressed in the leaked cable was contrary to the Brazilian-Argentine experience, which was characterized by mutual trust. In 2011, ABACC turned 20 years old and hosted an anniversary seminar, in Rio de Janeiro. On 6 May 2013, as part of the 2008 agreements, Redetec, a Brazilian administrative body responsible for managing resources for nuclear innovation, contracted Argentine company INVAP to build a multipurpose nuclear reactor in Brazil. It is expected that the Brazilian reactor will follow the Open-pool Australian lightwater reactor (OPAL) model, developed by INVAP for Australia. OPAL is used for research and for the production radioisotopes employed in nuclear medicine, industry, agriculture and environment. The agreed period for completion is 12 months and the amount paid by CNEN is R$24.7 million (US$12.02 million). The Multipurpose reactor will be stationed at the Marine Technology Center in São Paulo (Centro Tecnológico da Marinha em São Paulo – CTMSP), where the proper infrastructure will be built by the Brazilian company Intertechne. Taking into consideration the complexity of the construction project and all its necessary safety and security requirements, the reactor is expected to become operational in 2018. The total cost of this project is estimated to be US$500 million. Brazil and the nuclear non-proliferation regime Opposition to the NPT While Brazil participated actively in the international negotiations that led to the establishment of the NPT, it abstained from voting on the resolution that formally created the treaty. Brazilian government believed the NPT would inhibit technological and scientific progress of developing nations and consolidate the countries with nuclear weapons as a privileged minority in the international system. Brazil refused to sign the NPT for decades, conducting nuclear activities that were either under ad hoc safeguards agreements (e.g., the 1975 trilateral agreement between Brazil, West Germany, and the IAEA) or under no safeguards at all, such as the "autonomous" / "parallel" program. During the final months of Gerald Ford's U.S. presidency, there were negotiations between then-U.S. Under Secretary of State Charles W. Robinson and President Geisel, in which
