DEPARTMENT OF ENERGY


Proposed Subsequent Arrangement

AGENCY: Office of Nonproliferation and International Security, National 
Nuclear Security Administration, Department of Energy.

ACTION: Proposed subsequent arrangement.

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

SUMMARY: This notice is being issued under the authority of section 
131a. of the Atomic Energy Act of 1954, as amended. The Department is 
providing notice of a proposed subsequent arrangement under paragraph 2 
of Article 5 of the Agreement for Cooperation Between the Government of 
the United States of America and the Government of Japan Concerning 
Peaceful Uses of Nuclear Energy.

DATES: This subsequent arrangement will take effect no sooner than June 
9, 2011.

FOR FURTHER INFORMATION CONTACT: Mr. Sean Oehlbert, Office of 
Nonproliferation and International Security, National Nuclear Security 
Administration, Department of Energy. Telephone: 202-586-3806 or e-
mail: [email protected].

SUPPLEMENTARY INFORMATION: This subsequent arrangement concerns the 
alteration in form or content of 28.276 kg (24.541 ekg) of U.S.-origin 
highly enriched uranium (HEU) (26.342 kg U-235) and 0.0048 g of 
plutonium contained in three HEU driver fuels that have been irradiated 
in the YAYOI nuclear research reactor at the University of Tokyo in 
Tokai-mura, Japan. The University of Tokyo will off-load three HEU 
driver fuels from the core of YAYOI to be cut and de-cladded in the 
reactor room into approximately 140 pieces, each cut piece weighing 
approximately 200 g. The HEU will be converted to uranium oxide and 
downblended to approximately 18% at the Japan Atomic Energy Agency 
(JAEA) Plutonium Fuel Fabrication Facility, and then will be 
temporarily stored at the JAEA Tokai Plutonium Fuel Production 
Facility. The downblended HEU is planned for use as fuel for the JAEA 
experimental fast reactor JOYO. The alteration in form of the HEU will 
start in Japanese fiscal year 2012 and will continue for approximately 
one year.
    In accordance with section 131a. of the Atomic Energy Act of 1954, 
as amended, it has been determined that this subsequent arrangement 
concerning the storage or disposition of irradiated fuel elements will 
not be inimical to the common defense and security.

    Dated: May 11, 2011.

    For the Department of Energy.
Anne M. Harrington,
Deputy Administrator, Defense Nuclear Nonproliferation.
