Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

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.

How Saudi Arabia and China Could Partner on Solar Energy

| Jan. 24, 2019

Last May, Chinese solar panel manufacturer LONGi signed an agreement with Saudi trading company El Seif Group to establish large-scale solar manufacturing infrastructure in Saudi Arabia. The deal came several months after the Trump administration's imposition of global tariffs on imports of Chinese solar panels and cells.

The History of Fissile-Material Production in China

| Jan. 23, 2019

This article reconstructs the history of China’s production of highly enriched uranium and plutonium for nuclear weapons based on newly available public sources. It begins with discussion of China’s first set of fissile-material production facilities, which China started building in 1958. It then details the first and second “third-line” construction campaigns, initiated in 1964 and the late 1960s, respectively. Finally, the article considers the policy implications of the history of China’s fissile-material production, particularly its influence on China’s attitude toward negotiating a fissile-material cutoff treaty.

How the Next Nuclear Arms Race Will Be Different from the Last One

| 2019

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

China's Planned Floating Nuclear Power Facilities in South China Sea: Technical and Political Challenges

| Nov. 21, 2018

The operation of the fleet of Chinese floating nuclear power plants in the South China Sea carries with it numerous safety and security risks that may have widespread consequences to not only China but also to Southeast Asia and beyond.

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

Paper - Institute of Nuclear Materials Management

On China's Closed Fuel Cycle Strategies

| July 2018

As it expands its fleet of nuclear power plants, China faces an important decision: whether to make large capital investments in facilities to reprocess spent nuclear fuel and recycle the resulting plutonium in fast neutron reactors, or continue to store nuclear fuel, leaving for the future decisions on whether to reprocess the fuel or dispose of it as waste. In reaching a decision, policymakers should consider financial costs, the available fuel supply, nuclear security and proliferation risks, health and environmental dangers, and spent fuel management issues. This paper will first discuss the status of China’s breeder reactors and civilian reprocessing programs. It will then examine the costs and fuel supply issues associated with reprocessing.
