Nuclear Issues

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.

In this essay, Hui Zhang reviews the status of spent fuel storage in China.  He suggest that China should take steps to improve physical protection, reduce insider threats, promote a nuclear security culture, and improve nuclear cyber security. He also recommends China, South Korea, and Japans’ nuclear security training centers should cooperate and exchange best practices on insider threat reduction, contingency plans for emergency response, and discuss regional cooperation for long-term spent fuel storage, including building a regional center of spent fuel storage.

China initiated its nuclear weapon program in 1955 and began to construct its fissile-material production facilities in the late 1950s. China has produced highly enriched uranium (HEU) for weapons at two complexes: Lanzhou gaseous diffusion plant (GDP, also referred as Plant 504) and Heping GDP (the Jinkouhe facility of Plant 814).

In 1958, China started the construction of the Lanzhou plant with advice from Soviet experts. Moscow withdrew all its experts in August 1960, however, forcing China to become self-reliant. On January 14, 1964, the GDP began to produce 90% enriched uranium, which made possible China’s first nuclear test on 16 October 1964.

China has produced plutonium for weapons at two sites: 1) Jiuquan Atomic Energy Complex (Plant 404) in Jiuquan, Gansu province. This site includes China’s first plutonium reactor (reactor 801) and associated reprocessing facilities. 2) Guangyuan plutonium production complex (Plant 821), located at Guangyuan in Sichuan province. This “third line” site also included a plutonium reactor (reactor 821) and reprocessing facility. While China has not declared officially that it has ended HEU and plutonium production for weapons, it appears that China halted its HEU and plutonium production for weapons in 1987.1

Hui Zhang presented "Thoughts on China’s Nuclear Reprocessing Policy" at the Conference of Assessing the International Nuclear Agenda, June 16-17, 2017, in Beijing.

"From Hiroshima to the Cuban Missile Crisis, from arms races to arms control, from the Cold War and its proxy wars to the 2003 invasion of Iraq and the 2015 deal with Iran, few subjects have so consistently, and so controversially, concerned the American presidency as nuclear weapons have. A dozen men have been responsible for the decision to use the US nuclear arsenal since 1945, and whoever wins the election in November will inherit the responsibility for approximately 4,670 warheads at a time when relations with Russia (holder of 4,500 warheads) have reached a perilous low, a time when support for arms control is perhaps faltering, and a time when nuclear threats abound from the Middle East to the Korean Peninsula..."

"Today and tomorrow, world leaders will gather for what will likely be the final international summit on security for nuclear weapons and the materials needed to make them—a key tool for preventing nuclear terrorism. The last time this group met, at the 2014 Nuclear Security Summit in the Hague, they declared that preventing terrorists from acquiring nuclear weapons or weapons-usable materials remained “one of the most important challenges in the years to come.” Yet, since then, nuclear security has improved only marginally, while the capabilities of some terrorist groups, particularly the Islamic State, have grown dramatically, suggesting that in the net, the risk of nuclear terrorism may be higher than it was two years ago..."

"As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security...."
