The End of Cyber-Anarchy?

| January/February 2022

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Sovereign Wealth Funds in Small Open Economies

| Apr. 24, 2018

The small open economies of the Gulf and Southeast Asia are pioneers in the establishment of

Sovereign Wealth Funds (SWFs). The SWFs of countries like Qatar and Singapore are among the

world’s largest in terms of total asset size relative to Gross Domestic Product. This article looks

at the different compulsions behind the setting up of SWFs by small open economies.

New Ways to Detect Nuclear Misbehavior

| Jan. 08, 2018

If we had the technology to detect nuclear materials remotely it could help deter smuggling and make it easier to monitor international nuclear agreements. Several recent breakthroughs, if followed up with continued research and funding, could deliver on this promise. They include technological advances in x-ray and neutron radiography; a method that measures how plasma breaks down when exposed to a radioactive source; and developments in antineutrino detection. While all require more development and testing, they are important steps as the global need for ways to detect nuclear materials grows.

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.

Is There an Oil Weapon? Security Implications of Changes in the Structure of the International Oil Market

    Authors:

| Winter 2014/15

States have long worried that their dependence on oil gives producers a means of coercion. The oil market, however, is far larger and more integrated than it used to be. The potential for coercion differs across a series of distinct market segments. In this varied market, the United States remains the dominant force.

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..."
