Preventing Nuclear Terrorism

CSSS staff members undertake a wide range of research into the threat of nuclear and radiological terrorism and the actions that can be taken to mitigate these risks. This is an intrinsically interdisciplinary and applied area of research and as such our work brings together experts with backgrounds in mathematics, physics, social science and security studies and practitioners from international organisations, national governments and industry. Listed below is a short summary of current and past projects, research areas and publications.

Understanding Nuclear Risks

Over the years there have been many efforts by policy makers and academics to quantify the risk posed by nuclear terrorism. However, this is a far from simple task, as demonstrated by the outputs of different assessments which differ by up to nine orders of magnitude. Drawing on probability theory Bayesian and Frequentist approaches are used to show that nuclear terrorism should be considered as a ‘virtual risk’ and one that defies simple quantification. These issues are explored briefly in a paper prepared by Dr Robert Downes and Dr Christopher Hobbs for the IAEA 2016 Nuclear Security Conference in detail in a forthcoming article accepted for publication in the European Journal of International Security. This paper forms the basis for a future programme of research centred on decision making under uncertainty in the context of nuclear terrorism and nuclear risks generally, including those arising from civilian uses of nuclear and radiological material.

International Nuclear Security Regime 

President Obama’s inaugural foreign policy speech in Prague in 2009 elevated efforts to prevent nuclear terrorism to the forefront of the international security agenda. Stimulating intense discussion into both the effectiveness of formal and informal nuclear security initiatives and how international actions and standards might be further strengthened. Professor Wyn Bowen, Dr Alan Heyes and Hugh Chalmers evaluate the impact of the G8 Global Partnership against WMD, a multinational $20 billion CBRN threat reduction programme, in a RUSI Whitehall Paper. In an article published in International Affairs by Professor Wyn Bowen, Dr Matthew Cottee and Dr Christopher Hobbs, debunk arguments for a legally binding enforceable international nuclear security regime, advocating instead for pragmatic and incremental approaches to strengthening regime cohesion. In a narrowly focused article published in Strategic Analysis Professor Wyn Bowen and Dr Christopher Hobbs assess the challenges and options in strengthening nuclear information security, an area identified as a key policy gap at the 2012 Nuclear Security Summit (NSS) in Seoul. This article builds on a Foreign and Commonwealth Office (FCO) supported scoping study on the intangibles of nuclear security, carried out by CSSS in 2011, which also fed into the Multinational Statement on Nuclear Information Security presented by the UK at the Seoul Summit. CSSS staff have also investigated the role and purpose of the newly created Nuclear Security ‘Centres of Excellence’, with findings published as two Stanley Foundation Policy Analysis Briefs which discuss the key components of a ‘model centre’ and options to enhance collaboration between the nascent Centres in North East Asia. Ahead of the 2014 Nuclear Security Summit CSSS were funded by the FCO to produce a Nuclear Security Briefing Book, which outlines in detail how and why the international nuclear security regime has evolved from the 1970s to the present day. This was updated for the 2016 NSS with the intention of serving as a reference guide for participants in the summit process.

Nuclear Security in the Maritime Environment

Over the past two decades, billions of dollars have been spent on installing radiation detection equipment at ports and other maritime facilities around the world in an effort to detect illicitly trafficked nuclear and radiological materials. In a scoping study funded by UK Government and presented at Wilton Park in 2015 Dr Robert Downes, Dr Christopher Hobbs and Dr Daniel Salisbury assessed the intrinsic challenges for detecting and responding to the discovery of these materials in this environment and the effectiveness of the national systems currently in place. This report found that the implementation of detection systems and response mechanisms is highly fragmented and further research is currently being performed into the underlying reasons behind this divergence. CSSS staff also worked closely with the UK’s Department of Business Energy and Industrial Strategy (DBEIS) to provide input for the Best Practice Guide on Maritime Supply Chain Security presented at the 2016 NSS. CSSS have recently agreed a Coordinated Research Project with the International Atomic Energy Agency (IAEA) on alarm assessment for radiation detection systems at maritime facilities. Working in partnership with the Department of Informatics at KCL we will be analysing spectral data from tens of ports worldwide with the ultimate goal of designing an algorithm for use by front-line officers in support of their detection activities.

Radiological Source Security

CSSS staff members have also explored the issue of radiological terrorism. Professor Wyn Bowen and Jasper Pandza examine the role that deterrence by denial could play in preventing radiological terrorism as part of an edited book on Deterring Terrorism: Theory and Practice. In an article for IHS Janes Dr Robert Downes and Geoffrey Chapman discuss the radiological threat posed by the Islamic State. CSSS have also previously been funded by the Carnegie Cooperation of New York to explore an estimation methodology for state inventories of radioisotope holdings with a focus on sources that could be used in a ‘dirty bomb’.

Nuclear Security Culture

As part of our BEIS funded programme CSSS staff are working with the nuclear industry to investigate how the collective behaviour of individuals can influence the success and failure of nuclear security systems and how security culture can be both assessed and enhanced at the organisational level. As part of this we will be exploring how national cultures can impact on the implementation of nuclear security measures.

Nuclear Security Education

A founding member of the International Nuclear Security Education Network (INSEN) in 2010, CSSS staff members have been exploring the use of different pedagogical tools in teaching nuclear security through a succession of Professional Development Courses. In article published in the International Journal of Nuclear Security Dr Christopher Hobbs and Matthew Moran discuss the challenges and benefits of employing table-top exercises in this emergent area of education.
