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.

For more than a decade there has been talk of a global “nuclear renaissance,” and until recently Vietnam looked to be part of it, making plans to build nuclear infrastructure and taking the necessary steps to become a member of the international nuclear community. Then, last month, after a year or more of troubling signs, the government officially suspended its nuclear development plans.

In the late 2000s, energy forecasts began to use the term “nuclear renaissance” to refer to the fast-growing nuclear power program of China, and to the emergence of the so-called “nuclear aspirants” embarking on their first nuclear power projects. Many among these newcomers are members of the Association of Southeast Asian Nations (ASEAN). For this reason, nuclear suppliers like the United States, Russia, Japan, and South Korea have been particularly active in signing cooperation agreements with ASEAN nations or supporting these countries to explore the feasibility of nuclear energy.

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.

Faced with the twin pressures of a still-quickly growing economy and unprecedented smog from coal-fired plants, China is racing to expand its fleet of nuclear power plants. As it does so, Beijing is considering making large capital investments in facilities to reprocess spent nuclear fuel and recycle the resulting plutonium in fast neutron reactors that breed more plutonium. This report outlines the enormous costs China would likely face if it decides to build large-scale plants for reprocessing plutonium from spent nuclear fuel and recycling the plutonium in fast neutron reactors.

"Chinese President Xi Jinping reaffirmed at the global climate change conference in Paris that China pledged to achieve peak carbon dioxide emissions by around 2030, and to get around 20 percent of its primary energy from non-fossil sources by 2030. In 2014, China’s non-fossil energy consumption accounted for 11.2 percent of total energy use—hydro power was 8 percent, nuclear power was about 1 percent, and non-hydro renewable energy was around 2 percent—which is very close to the target of 11.4 percent set for 2015. Still, coal supplied the majority (66 percent) of China's total energy consumption in 2014, and oil accounted for about 18 percent of the energy mix. Natural gas, at 5 percent, still accounted for a relatively small share. To double the share of non-fossil sources by 2030, what role can nuclear power play?"

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.
