Assessing Nuclear Security Risks in Pakistan

| June 2023

Pakistan’s nuclear program and perceived nuclear security concerns have attracted global attention. The varying concerns range from the potential theft of nuclear weapons or materials to the unauthorized use of a nuclear device to terrorist groups taking control of the Pakistani government. The enduring debate, however, has oscillated between these doomsday scenarios and some optimistic considerations, where various quarters have shared their satisfaction over Pakistan’s nuclear security regime and its ability to deal with the emerging challenges. To address the evolving nature of these threats, Pakistan is constantly improving its nuclear security infrastructure. It has established a comprehensive legislative and institutional structure, nuclear security systems, and has also undertaken various international obligations. To further improve nuclear security perceptions, Pakistan should adopt a more transparent approach and learn from international best practices.

Russia’s Remaining Weapons Are Horrific and Confounding

| Mar. 23, 2022

Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Russia has used chemical weapons during past conflicts, notably in Chechnya and Syria, in violation of international law. Russian officials denied Biden’s accusation during a U.N. Security Council meeting Tuesday.

A Viable Nuclear Industry

| Summer 2021

Aditi Verma and Denia Djokić call for rethinking our collective approach to the benefits and risks of nuclear technology—a call that is crucial and timely. As humanity confronts the catastrophic consequences of climate change, questions related to the viability of nuclear energy to achieve a decarbonized world abound. The authors, however, push the boundaries of the current conversation by arguing that what is required to make nuclear energy “viable” for the twenty-first century is much more than just an exercise in technological development.

Risks to Persian Gulf Cities from Spent Fuel Fires at the Barakah and Bushehr Nuclear Power Plants

Interest in nuclear power has grown in some Middle Eastern states despite poor economics, seismic activity, and attacks on nuclear facilities in the region. This article assesses risks from cesium-137 release and dispersal from spent nuclear fuel fires at Barakah in the United Arab Emirates and Bushehr in Iran to public health, the water supply, and the food security of major Persian Gulf cities. Doha, Dammam, Al-Hofuf, and Manama are most at risk of receiving 1.5 MBq/m2 for a spent fuel fire at Barakah, while a spent fuel fire at Bushehr could affect Shiraz, Ahvaz, Basrah, and Kuwait City, albeit at lower probabilities. Absent a decision to end nuclear power in the region, options for reducing the potential risks of spent fuel fires on Persian Gulf populations include the timely transfer of spent fuel from pools into safer dry cask storage, multilateral disaster-response planning, and a commitment not to attack nuclear facilities.

The Nuclear, Humanities, and Social Science Nexus: Challenges and Opportunities for Speaking Across the Disciplinary Divides

| Aug. 07, 2021

The central aim of this special issue is to explore how research findings and insights from the humanities and social sciences can be used to shape and meaningfully inform the work of practitioners and policy makers in the nuclear energy sector and its corresponding areas of research and practice—all of which presently, in many ways, simultaneously face several challenges and opportunities and find themselves at a crossroads.

Increase in Frequency of Nuclear Power Outages Due to Changing Climate

| July 05, 2021

Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of climate change on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in nuclear power plants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100).

Security Under Strain? Protecting Nuclear Materials During the Coronavirus Pandemic

| June 28, 2021

The coronavirus pandemic has had a significant impact on the nuclear industry, complicating operations and altering the delivery of both safety and security. This has generated concerns over the ability of governments and industry to provide vital services, while also protecting against changing threats that have evolved to take advantage of the pandemic. Christopher Hobbs, Nickolas Roth and Daniel Salisbury examine the nuclear security community’s response to this challenge, exploring how the risk landscape has been changed by the pandemic and the efficacy of new security solutions.

What Can Nuclear Engineers Learn From Design Research?

| August 2021

Although nuclear reactor design is recognized as an essential skill and intellectual output of academic nuclear engineering, little attention has been paid within the discipline to the structure of the reactor design process and factors influencing design outcomes. This paper, which marks the first systematic attempt to explore the structure of the reactor design process and choices, applies methodological and theoretical tools developed within the mechanical engineering design studies field to the study of nuclear reactor design.

Public Opinion on Nuclear Energy and Nuclear Weapons: The Attitudinal Nexus in the United States

| October 2020

Does a lack of enthusiasm for nuclear energy among the U.S. public relate to connections with nuclear weapons? A critical area of public opinion remains understudied: the connection between nuclear energy and nuclear weapons. Scholars have theorized such a relationship in the public consciousness, but the premise has not been systematically investigated. The authors use two studies which provide evidence of psychological linkage. In fact, attitudes toward nuclear weapons may even drive those on nuclear energy.

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.
