Nuclear Issues

"While it remains to be seen how the Moon administration's nuclear energy and security policies will materialize, it is too early to conclude that Seoul is renouncing the option of nuclear hedging. Uncertainty over the US commitment to security alliances under President Trump, combined with the election of a South Korean president who is promoting more independent national security, makes it unlikely that South Korea is abandoning the hedging option altogether."

Reviewing recent developments in nuclear energy, it is clear that Northeast Asian countries have become the leading customers and suppliers of nuclear technology worldwide. However, regional cooperation in the nuclear field remains inadequate when compared to the close economic interaction between these states and their need for solutions to pressing issues, such as supply assurance and spent fuel management. At the same time, with events like the Fukushima accident or the ongoing nuclear crisis in North Korea, there is an urgent demand for Northeast Asia to improve the safety, security, and nonproliferation status of the regional nuclear programs as any nuclear-related incident in any regional state will have transnational impact on the economic and social stability of the whole region.

As India’s civilian nuclear energy program expands with the assistance of international nuclear suppliers, it creates new potential pathways to the acquisition of fissile material that could be diverted for military purposes. A key question is whether and how India’s civilian and military nuclear facilities are separated. In this discussion paper from the Belfer Center’s Project on Managing the Atom, Kalman A. Robertson and John Carlson argue that India has not established a complete and verifiable separation of its civilian and military nuclear programs. The authors recommend steps for India to take under its safeguards agreement with the International Atomic Energy Agency to provide assurances to all states that components of its civilian program are not contributing to the growth of its nuclear arsenal. These steps include renouncing options that would facilitate the use of safeguarded items to produce unsafeguarded nuclear material, and placing the proliferation-sensitive components of its nuclear power industry under continuous safeguards.

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

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.

"South Korea has been trying to develop its nuclear energy industry over half a century. Insufficient energy sources, increasing domestic energy consumption, and rising oil prices in the 1970s were significant drivers that turned South Korea into a nuclear energy producer. Today, the country runs 24 nuclear reactors in four nuclear power plant sites, the second highest number of reactors among Asian countries after Japan and fifth highest in the world. Despite the contribution of nuclear energy to the South Korean economy, however, the country is currently facing mounting domestic concerns over its pro-nuclear energy policy."

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.

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...

In this new oped for the Bulletin of the Atomic Scientist, MTA Associate Aaron Arnold and colleague Nikos Passas consider the role of banks in monitoring and verifying proliferation-related transactions. He outlines steps that the P5+1 and Iran can take in a final agreement that will allow them to remain vigilant about proliferation financing.
