(WASHINGTON, D.C.)—Today, Administrator Frank Klotz of the U.S. Department of Energy’s National Nuclear Security Administration and Chairman Un Chul Lee of the Republic of Korea’s (ROK) Nuclear Safety and Security Commission reached agreement on the terms of the Administrative Arrangement to the U.S.-ROK Peaceful Nuclear Cooperation Agreement (U.S.-ROK 123 Agreement). Building on the momentum from the recent launch of the High Level Bilateral Commission, conclusion of the Administrative Arrangement constitutes an important milestone in the further deepening of U.S.-ROK civil nuclear cooperation. 

A key requirement of the U.S.-ROK 123 Agreement, the Administrative Arrangement establishes the day-to-day terms that the U.S. and ROK officials will employ in implementing the provisions of the 123 Agreement. Notably, the Administrative Arrangement clarifies the measures the Parties will take to track and account for nuclear material subject to the 123 Agreement.  

Upon signing the Administrative Arrangement, Administrator Frank Klotz said, “Mindful of this week’s Nuclear Security Summit, this Administrative Arrangement further demonstrates the shared commitments of United States and the Republic of Korea in the further development of civil nuclear energy according to the highest nonproliferation norms.”
