Center Experts Reflect on 75th Anniversary of Hiroshima Bombing

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath.

Inadvertent Escalation and the Entanglement of Nuclear Command-and-Control Capabilities

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?

China's Uranium Enrichment Complex

| October 23, 2015

New public information allows a fresh estimate of China's current and under-construction uranium enrichment capacity. This paper uses open source information and commercial satellite imagery to identify and offer estimates of the capacity of China's 10 operating enrichment facilities, located at 4 sites, using centrifuge technology most likely based on adapting Russian technology. The total currently operating civilian centrifuge enrichment capacity is estimated to be about 4.5 million separative work units/year (SWU/year), with additional capacity estimated to be about 2 million SWU/year under construction. Also China could have an enrichment capacity of around 0.6 million SWU/year for non-weapon military uses (i.e., naval fuel) or dual use. These estimates are much larger than previous public estimates of China's total enrichment capacity. Further expansion of enrichment capacity may be likely since China will require about 9 million SWU/year by 2020 to meet the enriched uranium fuel needs for its planned nuclear power reactor capacity of 58 gigawatts-electric (GWe) by 2020 under its policy of self-sufficiency in the supply of enrichment services.

China is said to be building a demonstration commercial reprocessing plant

| Sep. 25, 2015

"China National Nuclear Corporation (CNNC) is reported to have started preparations for what appears to be a demonstration reprocessing plant with a capacity of 200 tonnes/year at Jinta near Jiuquan city of Gansu province. This site is over one hundred kilometer away from China's pilot reprocessing plant (located at Plant 404, the former Jiuquan plutonium production complex), The new demonstration plant is assumed to be based on a scale-up of the pilot plant which has a capacity of 50 tons/year. Works seems to be at a very preliminary site preparation stage..."

China's Uranium Enrichment Capacity: Rapid Expansion to Meet Commercial Needs

| August 20, 2015

Based on satellite imagery, Chinese publications, and discussions with Chinese experts, This report suggests that China has much more civilian enrichment capacity than previously thought, and even more is on the way. If these new estimates are correct, China has enough enrichment capacity to meet its nuclear power fuel requirements for the coming decade and beyond. Further, China will have excess enrichment capacity and will likely become a net exporter of commercial enrichment services.

Assessing an Iran Deal: 5 Big Lessons from History

| July 7, 2015

As the policy community prepares to assess an agreement between the U.S. and its P5+1 partners and Iran, Senate Foreign Relations Committee Chairman Bob Corker asked me to review the history of analogous agreements for lessons that illuminate the current challenge. In response to his assignment, I reviewed the seven decades of the nuclear era, during which the U.S. negotiated arms-control treaties, including the Non-Proliferation Treaty of 1968; strategic arms limitation talks and agreements from SALT to New Start; the North Korean accord of 1994; the agreements that helped eliminate nuclear weapons in Ukraine, Kazakhstan, and Belarus in the early 1990s; and the pact that eliminated the Libyan nuclear weapons program in 2003.

Among many lessons and clues from this instructive history, five stand out

Plutonium Reprocessing, Breeder Reactors, and Decades of Debate: A Chinese Response

| July 1, 2015

Some observers believe that plutonium reprocessing is on the verge of an expansion, while others argue that the end of the practice is in sight. The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...
