NNSA participated in the ninth meeting of the United States-Japan Nuclear Security Working Group (NSWG) in Tokyo on Aug. 30. The group was established in 2010 to demonstrate leadership in strengthening nuclear security worldwide. The NSWG is co-chaired by the National Security Council and Japan’s Ministry of Foreign Affairs. 

“The annual NSWG meeting provides a valuable opportunity for us to discuss our mutual nuclear security objectives with our Japanese colleagues,” said Brent Park, NNSA Deputy Administrator for Defense Nuclear Nonproliferation. “I appreciate the opportunity for frank and open dialogue that allows us to further efforts to keep nuclear materials out of the hands of terrorists.”

During the meeting, working group participants discussed strategies and activities pertaining to nuclear forensics, Japan’s Integrated Support Center for Nuclear Nonproliferation and Nuclear Security, implementing safeguards, transporting nuclear materials, minimizing highly enriched uranium, enhancing the physical protection of nuclear materials, reducing material attractiveness, and developing an integrated national response to potential incidents of materials found out of regulatory control.

The NSWG is one of five working groups under the U.S.-Japan Bilateral Commission on Civil Nuclear Cooperation. The commission enables comprehensive, strategic, and open dialogue on the safe and secure use of civil nuclear energy, global nuclear nonproliferation, emergency preparedness, and nuclear security.

In Tokyo, NSWG participants discussed recent commitments on minimizing the use of highly enriched uranium in civilian applications, participating in upcoming workshops on transportation security and nuclear forensics, and moving forward with the implementation of several International Atomic Energy Agency Joint Statements.

Participants also toured the Japan Atomic Energy Agency’s Virtual Reality System, the International Support Center for Nuclear Nonproliferation and Nuclear Security, and the Fast Critical Assembly.

Both nations reaffirmed their commitment to cooperation on these shared nuclear nonproliferation and security objectives and participants were encouraged to continue their efforts and report their outcomes during the next working group meeting, which will be held in the United States in 2019.

The U.S. delegation also included participants from the Department of State and the Nuclear Regulatory Commission.
