Nuclear Issues

China initiated its nuclear weapon program in 1955 and began to construct its fissile-material production facilities in the late 1950s. China has produced highly enriched uranium (HEU) for weapons at two complexes: Lanzhou gaseous diffusion plant (GDP, also referred as Plant 504) and Heping GDP (the Jinkouhe facility of Plant 814).

In 1958, China started the construction of the Lanzhou plant with advice from Soviet experts. Moscow withdrew all its experts in August 1960, however, forcing China to become self-reliant. On January 14, 1964, the GDP began to produce 90% enriched uranium, which made possible China’s first nuclear test on 16 October 1964.

China has produced plutonium for weapons at two sites: 1) Jiuquan Atomic Energy Complex (Plant 404) in Jiuquan, Gansu province. This site includes China’s first plutonium reactor (reactor 801) and associated reprocessing facilities. 2) Guangyuan plutonium production complex (Plant 821), located at Guangyuan in Sichuan province. This “third line” site also included a plutonium reactor (reactor 821) and reprocessing facility. While China has not declared officially that it has ended HEU and plutonium production for weapons, it appears that China halted its HEU and plutonium production for weapons in 1987.1

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

Many contributions have been made in the studies of the factors that influence public acceptance of nuclear power. However, previous studies seldom focused on nuclear power plants in the planning stage. Actually public perception is usually more sensitive at the preliminary planning stage of a nuclear power station. Mainly utilizing questionnaire survey and focus group methods, we have identified the factors that are correlated with local acceptance of planned nuclear power plants in China.

This paper will offer a significant new assessment of uranium enrichment capacity in China, based on satellite imagery, Chinese publications, and discussions with Chinese experts. It concludes that China has a lot more enrichment capacity now than we thought and even more on the way.

China’s approach to strengthening the security of its nuclear weapons, materials, and facilities is important in facilitating strong global action on nuclear security. At the 2014 Nuclear Security Summit in The Hague, Chinese President Xi Jinping made commitments to strengthening nuclear security.

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

Faced with the twin pressures of a still-quickly growing economy and unprecedented smog from coal-fired plants, China is racing to expand its fleet of nuclear power plants. As it does so, Beijing is considering making large capital investments in facilities to reprocess spent nuclear fuel and recycle the resulting plutonium in fast neutron reactors that breed more plutonium. This report outlines the enormous costs China would likely face if it decides to build large-scale plants for reprocessing plutonium from spent nuclear fuel and recycling the plutonium in fast neutron reactors.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."
