Nuclear Issues

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.

Why are governments willing to invest more time in sanctions and war than they do in diplomacy? I pondered this question as the five-year anniversary of the signing of the Joint Comprehensive Plan of Action, or Iran nuclear deal, passed last week. What would relations between the United States and Iran look like had diplomacy been given its due, and the Iran deal honoured for longer?   

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.

An explosion and fire at a workshop at Iran’s Natanz nuclear facility on July 2, which destroyed the better part of an entire building, was followed by a flurry of speculation about the cause. Perhaps a domestic dissident group had planted a bomb, a foreign government had conducted a cyberattack, or an underground gas pipeline simply exploded by accident. Iran’s Atomic Energy Organization announced on July 5 that it had determined the cause, but was withholding that information because of “security considerations.” Still, there is mounting circumstantial evidence that Israel and the United States were involved in what was a deliberate act of sabotage.

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.

Calder Walton writes that autocratic regimes — China, Russia and Iran — have been using social media to try to influence U.S. public opinion. History reveals how and why a one-party regime used disinformation to salvage its reputation following a disaster — the Soviet Union's 1986 Chernobyl nuclear catastrophe, whose history also reveals how such disinformation can be countered.

In 2011, the International Atomic Energy Agency (IAEA) released the fifth revision of its Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities. This update of IAEA nuclear security guidance was a significant improvement upon its predecessors, suggesting new and strengthened approaches to nuclear security in a range of areas. Nearly a decade later, however, the global nuclear security landscape has changed. Nuclear security regulations and practices have improved. International institutions and norms supporting global nuclear security architecture are stronger. Countries have made new political commitments to strengthening their nuclear security. Legally binding agreements are more widely subscribed than they were before. Meanwhile, new global threats have surfaced, presenting new challenges to physical protection systems. A range of emerging technologies creates new opportunities, but also new risks.

"The paradox of war is, the adversary will always move against your perceived weakness.  So a safe, secure and effective nuclear deterrent is there to ensure a war that can never be won, is never fought." Former Secretary of Defense James Mattis went on to say, "I am absolutely convinced that having this safe, secure, and effective deterrent is critical—the most critical piece of our nation's defense."  “At the end of the day, deterrence comes down to the men and women in uniform.” The question this paper addresses is: how do we motivate Airmen to give their best to perform this unsung duty, day after day, for years at a time?

As the world commemorates the 70th anniversary of the start of the Korean War, the Center for the National Interest's Korean Studies team decided to ask dozens of the world's top experts a simple question: Do you believe that the Korean War will finally come to an end before its next major anniversary in 2025? Joseph Nye provides his answer to that question.
