  • DOE/NNSA and IRSN collaborated on a study of gamma-ray instruments and analysis methods used to perform isotopic measurements of special nuclear materials. The two agencies agreed to collaborate on the project in response to inconsistencies that were found in the various versions of software and hardware used to determine the isotopic abundances of uranium and plutonium. IRSN used software developed internally to test the MGA and FRAM isotopic analysis codes for criteria used to stop data acquisition. The stop-criterion test revealed several unusual behaviors in both the MGA and FRAM software codes.
  • In September 1995, the US Department of Energy (DOE) and the Brazilian Comissao Nacional de Energia Nuclear (CNEN) signed an agreement on methods and technologies for safeguards applications. This agreement provides for cooperation in the areas of nuclear material control, accountancy, verification, physical protection, and advanced containment and surveillance technologies for international safeguards applications. CNEN is responsible for managing nuclear facilities and institutions in Brazil and is responsible for coordinating international safeguards as applied by the International Atomic Energy Agency (IAEA) and the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC). Following the ratification of the Quadripartite Agreementmore » among Argentina, Brazil, ABACC, and IAEA in March 1994, all nuclear materials in all nuclear activities in Brazil became subject to comprehensive safeguards. Collaboration between CNEN and DOE in 1996 is focusing on: (1) the use of a GRAND FORK detector at the Angra Nuclear Power Station, (2) a remote monitoring field trial, (3) workshops on environmental monitoring and analysis as a safeguards application, (4) developing and studying methods and techniques for applying safeguards at enrichment plants, and (5) support of CNEN`s safeguards analytical laboratory. This paper will describe each of the aforementioned safeguards cooperation activities.« less
  • In 1994, the US Department of Energy (DOE) and the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) signed a safeguards cooperation agreement. The agreement provides for cooperation in the areas of nuclear material control, accountancy, verification, and advanced containment and surveillance technologies for international safeguards applications. ABACC is an international safeguards organization responsible for verifying the commitments of a 1991 bilateral agreement between Argentina and Brazil in which both countries agreed to submit all nuclear material in all nuclear activities to a Common System of Accounting and Control of Nuclear Materials (SCCC). DOE provides critical assistance (includingmore » equipment and training) through the Office of Nonproliferation and National Security to countries and international organizations to enhance their capabilities to control and verify nuclear material inventories. Specific activities initiated under the safeguards agreement include: (1) active US participation in ABACC`s safeguards training courses, (2) joint development of specialized measurement training workshops, (3) characterization of laboratory standards, and (4) development and application of an extensive analytical laboratory comparison program. The results realized from these initial activities have been mutually beneficial in regard to strengthening the application of international safeguards in Argentina and Brazil.« less
  • A selected set of nondestructive assay instruments for an international safeguards system at uranium enrichment plants is currently under development. These instruments are of three types: in-line enrichment meters for feed, product, and tails streams; area radiation monitors for direct detection of high-enriched uranium production, and an enrichment meter for spent alumina trap material. The current status of the development of each of these instruments is discussed, with supporting data, as well as the role each would play in a total international safeguards system. 5 figures.
