Belfer Center experts offer insight and analysis of the Trump-Kim summit through statements and interviews.

President Trump surprised almost everyone—probably not the least Kim Jong-un—when he agreed to meet the North Korean leader at the end of May (now maybe early June). By accepting Kim’s invitation, President Trump overturned decades of conventional wisdom on how to separate North Korea from its nuclear and other WMD programs. If Trump and Kim meet—as of now this is still a big “if,” although North Korea has now confirmed its willingness to meet directly—the summit could be an important ice breaker and open up a chance to resolve the North Korean nuclear crisis and bring peace to the Korean peninsula. But success, however remote it may seem, will require new thinking and entail major risks. It will also require a plan.

This chapter assesses the Chinese position on the global nuclear disarmament and discusses the evolution of China's nuclear weapons strategy. Specifically focused on China's perspectives on the move toward nuclear disarmament and interim steps each side could take, and China's concerns that give rise to preconditions or conditions for deep cuts and/or abolition of nuclear weapons. Also examined is, why China's consistently maintained policies of no-first-use and minimum deterrence, the characteristics of China's nuclear strategy, and whether China would maintain its current nuclear strategy under a changing strategic dynamic in the future. Finally, it discusses the requirements of strategic stability between US and China, and the regional security dilemma.

"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.

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.

"Plutonium was first separated by the United States during the Second World War. Uranium was loaded into nuclear reactors, irradiated, cooled, and then chemically “reprocessed” in another facility to recover the plutonium. The reactors and the reprocessing plant were built as part of the secret atomic bomb project. Since then, eight other countries also have produced and separated plutonium for weapons..."

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...

Official plans in China call for a three-fold increase in nuclear energy by 2020, and much more is under consideration for the coming decades. How will China get the uranium it needs to feed its ambitious nuclear energy plans for the coming decades? This report suggests that between domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, the security of China’s uranium supply will not pose a challenge to China’s nuclear power development, even under the most ambitious scenarios for growth.

In this oped for the Bulletin of the Atomic Scientists, Hui Zhang contributes a third article to an international roundtable on reprocessing:
