On April 28, 2004, the United Nations Security Council, acting under Chapter VII of the UN Charter, unanimously passed UNSC 1540. The resolution "decided that all States shall refrain from providing any form of support to non-state actors" attempting to obtain or use weapons of mass destruction, "adopt and enforce appropriate effective laws" to that effect, and "take and enforce effective measures to "prevent the proliferation of" WMD. To carry out its part of this mandate, the UNSC established and renewed a Committee, which has mainly and usefully assisted States in adopting "appropriate effective laws." This study, in collaboration with Committee members, has focused on implementation mechanisms and indicators of performance in border and exports controls, securing materiel and facilities, and adapting controls to State needs. We conclude that the most meaningful measures of implementation need to be more broadly adopted and that the 1540 Committee needs a more extensive staff in order to extend its role to disseminate States' experience with those measures. We also conclude that mechanisms need to be developed to facilitate information sharing between the Committee and the private sector.

After the DPRK's nuclear test on October 9, 2006, denuclearization of the DPRK became an urgent issue that must be achieved as soon as possible to restrain an arms race in Northeast Asia. For denuclearization of the DPRK, issues of verification of dismantlement of the DPRK nuclear weapons programs are the most critical elements if an agreement can be reached between the U.S. and the DPRK. Objectives of the verification and dismantlement of the DPRK nuclear weapons programs are disposition of currently existing nuclear material, nuclear weapons, relevant facilities, nuclear workers and documents, and discontinuation of future clandestine production of those things, i.e., terminating the nuclear production capability of the DPRK. Kang will speak about technical aspects of the DPRK nuclear weapons program, including an idea on the disablement of 5 MWe graphite reactors at Yongbyon and major issues in the verification and dismantlement of the DPRK nuclear weapons programs.

Jungmin Kang is a science fellow at CISAC. Kang brings to the study of nuclear policy issues considerable expertise in technical analyses of nuclear energy issues, based on his studies in South Korea, Japan, and the United States. Kang has co-authored articles on the proliferation-resistance of advanced fuel cycles, spent-fuel storage, plutonium disposition, and South Korea's undeclared uranium enrichment and plutonium experiments. He has contributed many popular articles to South Korea's newspapers and magazines and is frequently interviewed about spent-fuel issues and the negotiations over North Korea's nuclear-weapon program. Kang's recent research focuses on technical analysis of issues related to nuclear weapons and energy of North Korea as well as spent-fuel issues in Northeast Asia. Kang serves on South Korea's Presidential Commission on Sustainable Development where he advises on nuclear energy policy and spent fuel management.

Kang received a PhD in nuclear engineering from Tokyo University, Japan, and MS and BS degrees in nuclear engineering from Seoul National University, South Korea. Kang worked in Princeton University's Program on Science and Global Security for two years in 1998-2000.

Within the last 10 years several non-proliferation programs have been realized in Uzbekistan. Those programs include actions on upgrading physical protection systems of facilities possessing nuclear reactors and powerful radioactive sources, measures on improving nuclear security and radioactive safety, equipping the country's exit/entry points in order to prevent illicit trafficking of nuclear and radioactive materials, improving safeguards and radioactive monitoring of environment. Special attention was given to conversion of research reactors to low enrichment uranium and treatment of highly enriched fresh and spent reactor fuel. The programs have been performed in cooperation with U.S. energy and defense departments, the International Atomic Energy Agency and related institutions.

Bekhzod Yuldashev is a CISAC science fellow. He served as a consultant-advisor at the International Atomic Energy Agency in 2006-2007.
