DEPARTMENT OF ENERGY


Office of International Regimes and Agreements; Proposed 
Subsequent Arrangement

AGENCY: Department of Energy.

ACTION: Notice of proposed subsequent arrangement.

-----------------------------------------------------------------------

SUMMARY: This notice is being issued under the authority of Section 131 
of the Atomic Energy Act of 1954, as amended (42 U.S.C. 2160). The 
Department is providing notice of a proposed ``subsequent arrangement'' 
under the Agreement for Cooperation in the Peaceful Uses of Nuclear 
Energy between the United States and Argentina.
    This subsequent arrangement requests to downblend material subject 
to an earlier subsequent arrangement--published in the Federal Register 
July 9, 2004 (69 FR 41460)--to a different level than previously 
approved. Under the 2004 subsequent arrangement, Comision Nacional de 
Energia Atomica (CNEA) was approved to downblend material from 89.79% 
enriched into low-enriched uranium (LEU). Under a contract with DOE's 
Global Threat Reduction Initiative program, CNEA has submitted the 
attached request to downblend 304 g of that material to 58% weight of 
isotope U235 rather than to LEU as originally approved. The 
material will be fabricated into test plates in Argentina and sent to 
Idaho National Laboratory for testing and irradiation. The material 
will remain in the United States after irradiation.
    In accordance with Section 131 of the Atomic Energy Act of 1954, as 
amended, we have determined that this subsequent arrangement will not 
be inimical to the common defense and security.
    This subsequent arrangement will take effect no sooner than fifteen 
days after the date of publication of this notice.

    For the Department of Energy.
Richard S. Goorevich,
Director, Office of International Regimes and Agreements.
