Nuclear Issues

The author analyzes the policy implications of the U.S. January 2019 Missile Defense Review.

The paper provides a detailed analysis of the contemporary Sino-Indian conventional ground and nuclear force balances and carefully reconstructs how mutual developments in these areas are perceived by both New Delhi and Beijing.

"Just as U.S. nuclear strategy and arsenal expansions affect those of China, China's nuclear shifts affect India's threat perceptions. Pakistan, in turn, pays close attention to any growth in Indian nuclear forces. To avoid a nuclear chain reaction in Asia, Congress should take a stand against proliferation and refuse to fund these new weapons programs."

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.

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.

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...

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