Nuclear Issues

On Friday, North Korea tested a missile than can deliver a nuclear weapon to almost any target in the continental United States, marking a major accomplishment for a state than many thought was on its last legs in the early 1990s. But far from dead, North Korea has managed to evade every political, military, and economic barrier that five successive U.S. presidents put in its way. Now, the United States under President Donald Trump has a massive but surmountable challenge on its hands—deterring a nuclear-armed North Korea and preserving and strengthening America’s alliances with South Korea and Japan, countries currently questioning whether Kim Jong Un’s new capabilities might prevent the United States from coming to their defense.

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to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...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:

The ninth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the UN Headquarters in New York from April 27-May 22, 2015. This is the fourth such conference since the indefinite extension of the NPT in 1995. Participating governments will discuss nuclear disarmament, non-proliferation, and the peaceful use of nuclear energy with a view to arriving at consensus on a number of issues.
