The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

The Global Economy Confronts Four Geopolitical Risks

| December 28, 2015

The end of the year is a good time to consider the risks that lie ahead of us. There are of course important economic risks, including the mispricing of assets caused by a decade of ultra-low interest rates, the shifts in demand caused by the Chinese economy’s changing structure, and European economies’ persistent weakness. But the main longer-term risks are geopolitical, stemming from four sources: Russia, China, the Middle East, and cyberspace.

Although the Soviet Union no longer exists, Russia remains a formidable nuclear power, with the ability to project force anywhere in the world. Russia is also economically weak because of its dependence on oil revenue at a time when prices are down dramatically. President Vladimir Putin has already warned Russians that they face austerity, because the government will no longer be able to afford the transfer benefits that it provided in recent years.

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.

China is said to be building a demonstration commercial reprocessing plant

| Sep. 25, 2015

"China National Nuclear Corporation (CNNC) is reported to have started preparations for what appears to be a demonstration reprocessing plant with a capacity of 200 tonnes/year at Jinta near Jiuquan city of Gansu province. This site is over one hundred kilometer away from China's pilot reprocessing plant (located at Plant 404, the former Jiuquan plutonium production complex), The new demonstration plant is assumed to be based on a scale-up of the pilot plant which has a capacity of 50 tons/year. Works seems to be at a very preliminary site preparation stage..."
