Name	Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials
Formation	1991
Headquarters	Rio de Janeiro; Buenos Aires
Region served	Brazil; Argentina
Membership	Argentina; Brazil
Leader title	President

Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) is a binational safeguards organization created to implement nuclear accounting and control between Argentina and Brazil. It was established to consolidate the bilateral confidence-building measures arising from the Brasília Declaration, the Argentina–Brazil Joint Declaration on Nuclear Policies, and the Tlatelolco Treaty regional context, integrating technical expertise from nuclear establishments in Buenos Aires and Rio de Janeiro. The agency operates alongside international frameworks including the International Atomic Energy Agency and shaped relations between the Comisión Nacional de Energía Atómica and the Comissão Nacional de Energia Nuclear.

History and Establishment

The agency traces origins to détente after the Falklands War era and initiatives such as the 1985 summit and the Declaration on Common Nuclear Policies (1990). Political leaders including Carlos Menem and Fernando Collor de Mello endorsed steps that culminated in a bilateral agreement signed in Brasília and Buenos Aires in 1991. The establishment followed precedents set by the Treaty of Tlatelolco and paralleled confidence-building measures seen in European cooperative models like the European Atomic Energy Community. Technical contributions came from institutions such as the Commissariat à l'énergie atomique-style laboratories and national research centers including Bariloche Atomic Centre and Centro Tecnológico da Marinha em São Paulo.

Organization and Governance

The agency is governed by a Joint Council composed of representatives from the Ministry of Foreign Affairs and the Itamaraty counterparts, with technical input from the Comisión Nacional de Energía Atómica and the Comissão Nacional de Energia Nuclear. Administrative organs mirror practices of the International Atomic Energy Agency and include a Presidency, an Executive Secretariat, and inspectorate units staffed by inspectors trained at national laboratories like Instituto de Engenharia Nuclear and the Instituto Balseiro. Governance mechanisms reference bilateral legal frameworks ratified by the Argentine National Congress and the National Congress of Brazil, and interact with domestic agencies such as the Ministry of Defense and the Ministry of Science, Technology and Innovation.

Functions and Activities

Core functions include nuclear material accountancy, physical inventory verification, and implementation of safeguards for facilities like research reactors at Bariloche and power reactors such as Atucha Nuclear Power Plant and Angra Nuclear Power Plant. The agency develops procedures for material control, reporting systems compatible with INFCIRC/153-style obligations, and collaborates on training programs with institutions such as the International Nuclear Safety Advisory Group-informed centers. Activities extend to joint inspections, data exchange with the International Atomic Energy Agency, and fostering transparency measures that influenced bilateral accords including the Quadripartite Agreement precedents in other regions.

Inspection and Verification Mechanisms

Inspection regimes combine routine and ad hoc verification, utilizing statistical sampling, item counting, and non-destructive assay technologies developed in cooperation with research centers like Centro Atómico Bariloche and Instituto de Engenharia Nuclear. Inspectors apply seals, surveillance, and remote monitoring protocols compatible with standards seen in INFCIRC/540 and coordinate complementarily with IAEA safeguards. Legal authority for access is framed by bilateral agreements approved by the Argentine judiciary and the Supreme Federal Court of Brazil when disputes arise. The agency reports inventory balances, measurement uncertainties, and reconciliation procedures to national authorities and to the International Atomic Energy Agency under cooperative arrangements.

International Cooperation and Agreements

The agency functions within a web of international instruments including the Treaty of Tlatelolco, the Non-Proliferation Treaty, and cooperative engagements with the International Atomic Energy Agency. It has been a model cited in dialogues with the Nuclear Suppliers Group, the Organization of American States, and during technical exchanges with nuclear authorities in South Africa, India, and Canada. Multilateral collaboration includes joint training with the Argentine-Brazilian Binational Commission formats and participation in international forums like the Nuclear Security Summit and meetings of the International Atomic Energy Agency General Conference.

Impact and Controversies

The agency is credited with reducing regional proliferation risks, advancing transparency between Argentina and Brazil, and enabling civilian nuclear cooperation that facilitated reactor operation at Atucha I, Atucha II, and Angra I/II. Critics have raised questions during periods of political tension involving leaders such as Cristina Fernández de Kirchner and Luiz Inácio Lula da Silva about sufficiency of oversight, while scholars referencing cases like the Iraq nuclear programme debate whether bilateral safeguards can fully substitute for multilateral inspections. Controversies have included disputes over access to military-adjacent sites, litigation in national courts, and technical disagreements over measurement standards influenced by international debates reflected at the IAEA Board of Governors.
