Nuclear Issues

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

Since 1983, China has had the objective of developing breeder reactors to run on recycled plutonium. Since 2004, it has been progressing through three stages of its plutonium recycling strategy: from pilot to demonstration to commercial facilities. At the first stage, in 2010, China began testing a pilot civilian reprocessing plant and running a small experimental fast reactor. Although those pilot facilities did not perform well, since 2015 China has moved forward to the second stage, which includes a demonstration reprocessing plant, a mixed-oxide fuel facility, and two demonstration liquid-sodium-cooled fast-neutron reactors. Recent satellite images and other information show construction of those demonstration facilities is actively underway. Meanwhile, the China National Nuclear Corporation is pushing toward the third stage by negotiating with France’s nuclear fuel cycle company Orano (formerly Areva) over the purchase of a large commercial reprocessing plant, and has proposed construction of large commercial fast-neutron reactors by 2028.

Since 2010, China has significantly expanded its indigenous enrichment capacity to meet the expected rapid increase of enrichment requirements. Meanwhile, China has expanded its plutonium reprocessing and recycling capabilities for “saving uranium.” The purpose of this report is to provide a better understanding of the development of China’s uranium enrichment and plutonium recycling programs.

China pursues actively its closed fuel-cycle policy. In 2010, it began testing a pilot civilian reprocessing plant (50 tHM/year). In 2015, China began construction of the demonstration reprocessing plant (200 tHM/year). China has also been negotiating with France over the purchase of a commercial reprocessing plant with a capacity of 800 tHM/year. China’s Experimental Fast Reactor (20 MWe) started operation in 2010. Construction of the CFR-600 demonstration fast reactor began in 2017. This work will assess those plutonium separation and recycling programs. Further, it will estimate their cumulative plutonium production and discuss the potential uses of separated plutonium in China’s fast reactors over next two decades.

China leads the world in term of nuclear power development pace and new reactor construction. To meet the expected rapid increase of enrichment requirements, since 2010 the China National Nuclear Corporation (CNNC) has expanded significantly its indigenous centrifuge enrichment capacity. However, China does not officially release information on its enrichment capacity. Based on satellite imagery, Chinese publications, and discussions with Chinese experts, this work will examine the current status of China's uranium-enrichment development and offer significant new estimates of the capacity of China's operating enrichment facilities.

Since 2015 China has shown it is quickly modernising its nuclear force through adding more and “better” intercontinental ballistic missiles (ICBMs) and multiple independently targetable re-entry vehicles (MIRVs).Based on Chinese publications and Western governmental and non-governmental estimates, this author estimates that in 2020 China has a total inventory of approximately 360±50 nuclear warheads. This stockpile is likely to grow further over the next decade as additional nuclear capable missiles become operational. In particular, China nuclear force modernization has been driven mainly by expansion in US missile defence programmes as many Chinese believe. China’s arsenal may be somewhat larger than France’s but is much smaller than the US and Russia.

Over the last decade, China has been actively pursuing plans to recycle its spent nuclear fuel. In 2010, it began testing a pilot civilian plutonium reprocessing plant with a design capacity to produce about 50 metric tons of heavy metal per year at the Jiuquan nuclear complex in Gansu province (known as Plant 404). In July 2015, the China National Nuclear Corporation started construction of a larger demonstration reprocessing plant at the Gansu Nuclear Technology Industrial Park in Jinta, Gansu Province, about 100 kilometers from the Jinquan pilot plant. The demonstration reprocessing plant, which has a planned capacity of 200 metric tons per year, is to be commissioned in 2025.

Fueled by aggressive rhetoric from both capitals, Indian and Chinese ground forces engaged in a standoff between June and August 2017. The Doklam crisis, as it became known, stimulated introspection among officials and experts in both states about the future of their relationship. Politically, both strategic communities largely concluded that the peaceful resolution of border disputes is now less likely, forecasting more rivalry than cooperation. Militarily, Indian discussions on the strength of its military position against China in their disputed ground frontier areas have converged on the view that China holds the conventional and nuclear edge over India in this domain.

Based on our analysis of data on the location and capabilities of Indian and Chinese strategic forces and related military units, we conclude that this assessment of the balance of forces may be mistaken and a poor guide for Indian security and procurement policies. We recommend that instead of investing in new nuclear weapons platforms that our analysis suggests are not likely to be required to deter China, New Delhi should improve the survivability of its existing forces and fill the gap in global arms control leadership with an initiative on restraint and transparency.
