Nuclear Issues

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

2023 marked eighty years since the wartime adoption of the BRUSA Agreement between Great Britain and the United States. This 1943 document codified the growing relationship between U.S. and U.K. signals intelligence organizations and included policies governing the exchange of personnel and joint regulations for handling sensitive material. Security directives and protocols aligned operational processes between the democratic governments, setting new cooperative standards for nation-states battling authoritarian regimes.

By looking beyond solely Iran’s security motivations, this paper by Sahar Nowrouzzadeh seeks to inform more holistic negotiation strategies that can potentially influence Iran’s nuclear decision-making in a manner more favorable to U.S. interests.

Under the guidance of its self-defence nuclear strategy, China will continue to modernise its nuclear force in order to maintain a reliable second-strike retaliatory capability. China’s nuclear weapon modernisation has been responsive to the advances of military capabilities of other countries, particularly the US. As Hu Side emphasised, “The sole purpose for China to maintain a limited nuclear counterattack force is to deter a potential nuclear strike. However, the development of US missile defense and the long-rang strike capability with high accuracy to target mobile missiles is in practice to decrease the effectiveness of Chinese nuclear deterrence. Thus, it surely leads to Chinese attention."

The Wisconsin Project on Nuclear Arms Control hosted two roundtables—in September 2019 and March 2021—to identify lessons that should be drawn from the archive of Iranian documents seized by Israel in 2018, related to the effectiveness of export controls, monitoring measures such as international inspections, and other efforts to prevent material and expertise from reaching programs to develop nuclear weapons. Informed by these lessons, the group sought to develop a set of findings and recommendations to support the policymaking and monitoring communities.

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.

With concerns and uncertainties regarding Iran’s nuclear future persisting to this day, this paper seeks to review the TRR negotiations and the context in which they unfolded in order to capture some of the lessons of negotiating with Iran regarding its nuclear program, primarily from the viewpoint of senior U.S. officials involved at the time. The paper is also informed by the personal perspective of one of the authors (Poneman) who led the U.S. delegation in the 2009 Vienna talks, and who, prior to this publication, had not publicly elaborated on his experience. The other author (Nowrouzzadeh), who supported the TRR talks in an analytical capacity within the U.S. Department of Defense, also conducted an extensive interview with Poneman as part of their collaboration on this paper. By drawing on existing literature and recent interviews with several senior U.S. officials involved in the negotiations now that over ten years have passed, the authors seek to draw useful lessons from this episode that can assist policymakers in understanding Iran’s nuclear decision-making and in their continued efforts to shape the future trajectory of Iran’s nuclear program.

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.
