To Enhance National Security, the Biden Administration Will Have to Trim an Exorbitant Defense Wish List

| Mar. 13, 2024

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Enabling a Significant Nuclear Role in China’s Decarbonization

| Dec. 02, 2021

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.

A Threat to Confront: Far-Right Extremists and Nuclear Terrorism

| Jan. 14, 2021

Every president serving in the last two decades has said that nuclear terrorism is a significant national security threat. Analysis of this threat has been, for good reason, mostly focused on foreign extremist groups, but recent events raise questions of whether there should be greater focus in the United States on far-right, domestic extremist threats. These extremists represent a unique danger because of their prevalence in federal institutions such as the military and the potential that they might infiltrate nuclear facilities, where they could access sensitive information and nuclear materials.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.

China's Nuclear Spent Fuel Management and Nuclear Security Issues

| Nov. 10, 2017

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.

The History of Highly Enriched Uranium Production in China

| July 2017

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.

The History of Plutonium Production in China

| July 2017

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
