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.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

Chinese president Xi Jinping said in his address at the 2014 Nuclear Security Summit that, “we should place equal emphasis on development [of nuclear energy] and security, and develop nuclear energy on the premise of security.” He further emphasized that, “developing nuclear energy at the expense of security can neither be sustainable nor bring real development. Only by adopting credible steps and safeguards can we keep the risks under effective control and develop nuclear energy in a sustainable way."

Since September 11, 2001, China has substantially advanced its physical protection system, with a switch in focus from the traditional "guns, gates, guards" approach to an effective mixed approach, combining personnel with modern techniques. Then-Chinese President Hu Jintao emphasized at the 2012 Nuclear Security Summit that, "In the future, China will further take nuclear security measures, make sure the security of its own nuclear materials and facilities, improve the overall nuclear security." This paper examines the specific and detailed physical protection approaches that are currently applied to China's nuclear power plants, and recommends further steps to improve China's existing nuclear security system.
