# SUPPLEMENTARY INFORMATION:

This subsequent arrangement concerns the retransfer of 9.2 kilograms of U.S.-origin atomized low-enriched uranium-8wt. % molybdenum powder, 19.734 percent enrichment, from Korea Atomic Energy Research Institute (KAERI) in Daejeon, South Korea to Comisión Nacional de Energía Atómica (CNEA) in Buenos Aires, Argentina. The material, which is currently located at and prepared by KAERI, will be used for qualification testing of plate-type nuclear fuel as part of a Reduced Enrichment for Research and Test Reactors (RERTR) program by CNEA. The material was originally obtained by KAERI from U.S. Department of Energy's National Nuclear Security Administration Y-12 National Security Complex pursuant to export license XSNM3613.

In accordance with section 131a. of the Atomic Energy Act of 1954, as amended, it has been determined that this subsequent arrangement concerning the retransfer of nuclear material of United States origin will not be inimical to the common defense and security.
