As India’s civilian nuclear energy program expands with the assistance of international nuclear suppliers, it creates new potential pathways to the acquisition of fissile material that could be diverted for military purposes. A key question is whether and how India’s civilian and military nuclear facilities are separated. In this discussion paper from the Belfer Center’s Project on Managing the Atom, Kalman A. Robertson and John Carlson argue that India has not established a complete and verifiable separation of its civilian and military nuclear programs. The authors recommend steps for India to take under its safeguards agreement with the International Atomic Energy Agency to provide assurances to all states that components of its civilian program are not contributing to the growth of its nuclear arsenal. These steps include renouncing options that would facilitate the use of safeguarded items to produce unsafeguarded nuclear material, and placing the proliferation-sensitive components of its nuclear power industry under continuous safeguards.

"With the aftermath of the Iran agreement hanging in the air, words such as “centrifuge,” “enrichment,” and “uranium” are still appearing regularly in news coverage. Which means that now is a good time to look at the enrichment capacity of a much larger power, thousands of miles away: China. The country’s enrichment capacity is a topic about which little has appeared in the popular press—possibly because little is publicly known, and what information there is has to be assembled, verified, and evaluated from many different independent sources."

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.

"South Korea has been trying to develop its nuclear energy industry over half a century. Insufficient energy sources, increasing domestic energy consumption, and rising oil prices in the 1970s were significant drivers that turned South Korea into a nuclear energy producer. Today, the country runs 24 nuclear reactors in four nuclear power plant sites, the second highest number of reactors among Asian countries after Japan and fifth highest in the world. Despite the contribution of nuclear energy to the South Korean economy, however, the country is currently facing mounting domestic concerns over its pro-nuclear energy policy."

Scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere.

International trade has become the fastest growing driver of global carbon emissions, with large quantities of emissions embodied in exports from emerging economies. International trade with emerging economies poses a dilemma for climate and trade policy: to the extent emerging markets have comparative advantages in manufacturing, such trade is economically efficient and desirable. However, if carbon-intensive manufacturing in emerging countries such as China entails drastically more CO2 emissions than making the same product elsewhere, then trade increases global CO2 emissions.

Based on satellite imagery, Chinese publications, and discussions with Chinese experts, This report suggests that China has much more civilian enrichment capacity than previously thought, and even more is on the way. If these new estimates are correct, China has enough enrichment capacity to meet its nuclear power fuel requirements for the coming decade and beyond. Further, China will have excess enrichment capacity and will likely become a net exporter of commercial enrichment services.

Some observers believe that plutonium reprocessing is on the verge of an expansion, while others argue that the end of the practice is in sight. The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...

China is the world's largest emitter of carbon dioxide, accounting for one-quarter of the global total in 2013. Although the country has successfully lowered the rate of emissions from industry in some cities through improved technology and energy-efficiency measures, rapid economic growth means that more emissions are being added than removed. Without mitigation, China's CO2 emissions will rise by more than 50% in the next 15 years.
