The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

Combating Nuclear Smuggling? Exploring Drivers and Challenges to Detecting Nuclear and Radiological Materials at Maritime Facilities

| June 03, 2019

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.

'Wean Them Away from French Tutelage': Franco-Indian Nuclear Relations and Anglo-American Anxieties During the Early Cold War, 1948–1952

| October 2015

Based on multi-archival research, this article explores the significance of Franco-Indian nuclear relations against the backdrop of Anglo-American endeavours to censor information related to atomic energy and to secure control of strategic minerals during the early Cold War.

Uranium Supplies: A Hitch to China’s Nuclear Energy Plans? Or not?

| May 6, 2015

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.

Securing Chinese Nuclear Power Development: Further Strengthening Nuclear Security

| September, 2014

Chinese President Xi Jinping addresses China’s new concept of nuclear security with four “equal emphasis” at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi’s political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China’s existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

Symposium on the Non-Proliferation Treaty, Nuclear Disarmament, Non-proliferation, and Energy: Fresh Ideas for the Future

Dec. 15, 2014

The ninth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the UN Headquarters in New York from April 27-May 22, 2015. This is the fourth such conference since the indefinite extension of the NPT in 1995. Participating governments will discuss nuclear disarmament, non-proliferation, and the peaceful use of nuclear energy with a view to arriving at consensus on a number of issues.
