China's Uranium Enrichment Complex

| October 23, 2015

New public information allows a fresh estimate of China's current and under-construction uranium enrichment capacity. This paper uses open source information and commercial satellite imagery to identify and offer estimates of the capacity of China's 10 operating enrichment facilities, located at 4 sites, using centrifuge technology most likely based on adapting Russian technology. The total currently operating civilian centrifuge enrichment capacity is estimated to be about 4.5 million separative work units/year (SWU/year), with additional capacity estimated to be about 2 million SWU/year under construction. Also China could have an enrichment capacity of around 0.6 million SWU/year for non-weapon military uses (i.e., naval fuel) or dual use. These estimates are much larger than previous public estimates of China's total enrichment capacity. Further expansion of enrichment capacity may be likely since China will require about 9 million SWU/year by 2020 to meet the enriched uranium fuel needs for its planned nuclear power reactor capacity of 58 gigawatts-electric (GWe) by 2020 under its policy of self-sufficiency in the supply of enrichment services.

Crucial Questions Remain as Iran Nuclear Talks Approach Deadline

| June 28, 2015

Iran’s top nuclear negotiator was heading back to Tehran on Sunday to consult with his nation’s leadership, as negotiators remained divided over how to limit and monitor Tehran’s nuclear program and even on how to interpret the preliminary agreement they reached two months ago.

Uranium Supplies: A Hitch to China’s Nuclear Energy Plans? Or not?

| May 6, 2015

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.

The Key to the North Korean Targeted Sanctions Puzzle

| November 1, 2014

"At no point in the history of U.S. nonproliferation and counterproliferation policy have financial sanctions been so central to U.S. efforts to prevent or rollback the acquisition of nuclear weapons in countries such as North Korea and Iran. Despite this crucial role, financial sanctions have been examined almost solely from the sender’s perspective, that is, the country imposing the sanctions. Few focused policy analyses have measured the effects of these instruments from the target’s perspective..."

The Nonproliferation Emperor Has No Clothes: The Gas Centrifuge, Supply-Side Controls, and the Future of Nuclear Proliferation

| Spring 2014

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

Securing China’s Weapon-Usable Nuclear Materials

| Feb 18, 2014

This article describes the status of China’s military and civilian nuclear programs, fissile material production and associated nuclear facilities, and the Chinese nuclear experts and officials’ perspectives on the nuclear terrorism threat. It gives details of China’s nuclear security practices, attitudes, and regulations, as well as identifying areas of concern. The article recommends ways to strengthen China’s nuclear material protection, control, and accounting systems and suggests opportunities for increased international cooperation.

A Multinational Fuel Consortium: Obstacles, Options, and Ways Forward

| July 1, 2011

The World Nuclear Association estimates that by 2030, 600 nuclear reactors will be in operation around the world; 60 countries are considering nuclear power, out of which 10 to 25 are expected to bring nuclear power plants on line by 2030. This could lead, writes Olli Heinonen, to the construction of additional uranium enrichment plants, which, with adjustments, can produce material for nuclear weapons.

Nuclear Power Without Nuclear Proliferation?

| Fall 2009

Will the growth of nuclear power lead to increased risks of nuclear weapons proliferation and nuclear terrorism? Will the nonproliferation regime be adequate to ensure safety and security in a world more widely and heavily invested in nuclear power? The authors in this two-volume (Fall 2009 and Winter 2010) special issue of Dædalus have one simple and clear answer to these questions: It depends.

Enabling a Nuclear Revival—and Managing Its Risks

| Fall 2009

Matthew Bunn and Martin B. Malin examine the conditions needed for nuclear energy to grow on a scale large enough for it to be a significant part of the world’s response to climate change. They consider the safety, security, nonproliferation, and waste management risks associated with such growth and recommend approaches to managing these risks. Bunn and Malin argue that although technological solutions may contribute to nuclear expansion in the coming decades, in the near term, creating the conditions for large-scale nuclear energy growth will require major international institutional innovation.

Spreading Temptation: Proliferation and Peaceful Nuclear Cooperation Agreements

| Summer 2009

Matthew Fuhrmann's article "Spreading Temptation: Proliferation and Peaceful Nuclear Cooperation Agreements," was published by in the Summer 2009 issue of International Security. In his article, Dr. Fuhrmann argues "Peaceful nuclear cooperation—the transfer of nuclear technology, materials, or know-how from one state to another for peaceful purposes—leads to the spread of nuclear weapons. With a renaissance in nuclear power on the horizon, major suppliers, including the United States, should reconsider their willingness to assist other countries in developing peaceful nuclear programs."
