Science, Technology, and Public Policy

The authors analyze the 1979 Three Mile Island nuclear accident and the recent back-to-back crashes of two Boeing 737 Max jets and make policy recommendations for the regulation of increasingly complex technologies.

For true political and strategic stability in Southern Asia, China must be involved as a committed party to India-Pakistan confidence building measures, argues Frank O'Donnell in South Asian Voices' series, "Twenty Years Into Nuclear South Asia."

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.

Last week, President Trump signed a new executive order that paves the way to impose sanctions against any foreign bank that conducts business with North Korea, going well beyond current UN financial sanctions. These so-called secondary sanctions, which are penalties applied to third-party foreign banks (i.e., not directly against North Korean entities), are particularly focused on Chinese banks.

"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."

Iran announced last week that it would start feeding its first IR-8 centrifuges with uranium hexafluoride gas (UF6). The 2015 Iran nuclear deal states that Tehran’s breakout time (the time needed to enrich uranium enough for a nuclear bomb) is one year, but that is based on Iran only using the first-generation, less-efficient IR-1 centrifuges. With more powerful IR-8s and other advanced centrifuges, Iran could enrich uranium for a weapon much faster. In three to four years, the country could be able to deploy large numbers of advanced centrifuges – if it can convince the international community that its nuclear program is peaceful and that it should be treated like any other nation, without restriction on its nuclear and enrichment activities.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.
