Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

Many contributions have been made in the studies of the factors that influence public acceptance of nuclear power. However, previous studies seldom focused on nuclear power plants in the planning stage. Actually public perception is usually more sensitive at the preliminary planning stage of a nuclear power station. Mainly utilizing questionnaire survey and focus group methods, we have identified the factors that are correlated with local acceptance of planned nuclear power plants in China.

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

This paper will offer a significant new assessment of uranium enrichment capacity in China, based on satellite imagery, Chinese publications, and discussions with Chinese experts. It concludes that China has a lot more enrichment capacity now than we thought and even more on the way.

China’s approach to strengthening the security of its nuclear weapons, materials, and facilities is important in facilitating strong global action on nuclear security. At the 2014 Nuclear Security Summit in The Hague, Chinese President Xi Jinping made commitments to strengthening nuclear security.

As India’s civilian nuclear energy program expands with the assistance of international nuclear suppliers, it creates new potential pathways to the acquisition of fissile material that could be diverted for military purposes. A key question is whether and how India’s civilian and military nuclear facilities are separated. In this discussion paper from the Belfer Center’s Project on Managing the Atom, Kalman A. Robertson and John Carlson argue that India has not established a complete and verifiable separation of its civilian and military nuclear programs. The authors recommend steps for India to take under its safeguards agreement with the International Atomic Energy Agency to provide assurances to all states that components of its civilian program are not contributing to the growth of its nuclear arsenal. These steps include renouncing options that would facilitate the use of safeguarded items to produce unsafeguarded nuclear material, and placing the proliferation-sensitive components of its nuclear power industry under continuous safeguards.

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.
