Nuclear Issues

The authors analyze the 1979 Three Mile Island nuclear accident and the recent back-to-back crashes of two Boeing 737 Max jets and make policy recommendations for the regulation of increasingly complex technologies.

Steven E. Miller writes that U.S. withdrawal from the Intermediate Range Nuclear Forces Treaty offers few benefits and solves no significant security problem, while raising some potential costs and obvious disadvantages.

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.

"The partial budget blueprint released by the White House recently will put U.S. leadership in science and technology at serious risk if Congress goes along. In addition to the obvious damage that would result from the proposed $5.8 billion cut at NIH, the $2 billion cut in applied energy R&D, the $900 million cut in DOE’s Office of Science, the abolition of ARPA-E, and the research cuts at NOAA and EPA, a less immediately obvious potential casualty would be U.S. scientific cooperation with a wide variety of other countries on a wide variety of topics."
