Nuclear Issues

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

Hamidreza Azizi and Nicole Grajewski analyze Russian Foreign Minister Sergei Lavrov's recent demands  for written guarantees that Western sanctions over Ukraine "will by no means affect our right to free and full-fledged trading, economic, investment, military and technical cooperation with Iran."

Concerns are mounting about the safety of Ukraine’s 15 nuclear reactors and the possibility of an ecological disaster in the midst of the Russian invasion.

“There are contingencies but I doubt that these power plants have prepared for a full-scale invasion,” said Mariana Budjeryn, a Ukrainian research associate with Harvard University’s project on managing the atom. “In the middle of a large scale conflict, there’s a myriad of things that could happen, for which normal, even very robust, safety procedures at a nuclear power plant [would be insufficient].”

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

1. We must learn from and remember the lessons of the past—while recognizing that Fukushima is not going to “happen again” as future accidents will have their own characteristics; while remembering the past, we must also avail ourselves of advances in seismology, climatology, engineering, etc.

As the COVID-19 pandemic devastates the world, nuclear power plants must remain safe and secure to provide electricity for food supply chains, emergency response teams, hospitals, and telecommunications in countries home to more than half of all people. Meanwhile, the Islamic State terror group has already announced its intent to exploit the pandemic, and other violent extremist organizations are also taking pains to use the crisis for their own purposes.
