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).

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.

Nonproliferation and Security Implications of the Evolving Civil Nuclear Export Market

| Mar. 27, 2019

In recent decades, the nuclear export market has observed a marked shift of demand from traditional customers in the Western world to Asia. The lack of projects in the United States, the delay in the French construction of advanced reactors, and the Fukushima accident in Japan have also led to the declining export capabilities of their companies. In contrast, Russia has gained numerous contracts, and China will likely become another major exporter. In this paper, the evolution of the market was examined from both the supply and demand sides with issues including the more concentrated and uncertain market, the lack of full participation by emerging suppliers to the nonproliferation regime, and the lesser governance capabilities of the newcomers. Addressing these issues, a range of policy suggestions was made, including the reinforcement of market shares of Western suppliers, the encouragement of newcomers to adhere to international norms, and a better safeguards contribution scheme.

An Analysis of Moon Jae-in's Nuclear Phase-out Policy

| Winter 2019

Although South Korea adopted nuclear energy later than countries like the United States, Russia, or France, the country, until recently, has been considered to have one of the most successful civil nuclear power programs in the world, with a fully-devel- oped supply chain, a remarkable record in constructing and operating nuclear power plants (NPPs), and the ability to compete and win contracts to supply NPPs abroad. The fortune of South Korea’s nuclear program has seemingly come to an end, however, with the election of Moon Jae-in. The new South Korean President promised to reduce the country’s dependence on nuclear energy, and has, since taking office, implemented measures to phase out this type of electricity generation.

In this paper, following a brief history of the development of nuclear energy in South Korea, the root causes that instilled public distrust of nuclear energy and Moon Jae-in’s phase-out policy are discussed. Subsequently, by analyzing the validity of Moon’s plan, I argue that this phase-out policy is not beneficial for the long-term sustainability of South Korea’s economy in general, and of the Korean nuclear industry in particular. The paper concludes with policy recommendations for a more balanced nuclear policy that can accommodate public opinion and, at the same time, ensure energy security and provide other economic and diplomatic benefits.

China's Planned Floating Nuclear Power Facilities in South China Sea: Technical and Political Challenges

| Nov. 21, 2018

The operation of the fleet of Chinese floating nuclear power plants in the South China Sea carries with it numerous safety and security risks that may have widespread consequences to not only China but also to Southeast Asia and beyond.

Nuclear Energy in the Middle East? Regional Security Cooperation Needed

| Spring 2017

Nuclear power in the Middle East has appeared poised for dramatic growth for more than a decade.  Iran’s nuclear power plant at Bushehr, the first of its kind in the Middle East, began producing electricity in 2011. Tehran has plans or proposals for additional 11 reactors, according to the World Nuclear Association. Saudi Arabia has announced plans to build 16 nuclear power reactors by 2040. The UAE has four nuclear power reactors under construction, the first of which is expected to come online later this year.  Egypt, Turkey, and Jordan, are each pursuing the development nuclear energy at their own pace.  The appearance of activity is impressive.

By Accident or by Design? Pushing Global Governance of Nuclear Safety

| August 2017

Nuclear safety governance should move towards a more robust regime including elements of international monitoring and verification. This is needed because nuclear energy production is likely to grow and new reactors will have different global dispersal, veering towards less experienced countries. In addition, there is growing interest in international and multilateral collaboration on disposal of mounting nuclear waste.

Sustainability, Ethics and Nuclear Energy: Escaping the Dichotomy

| March 2017

In this article, the authors suggest considering sustainability as a moral framework based on social justice, which can be used to evaluate technological choices. In order to make sustainability applicable to discussions of nuclear energy production and waste management, they focus on three key ethical questions, namely: (i) what should be sustained; (ii) why should we sustain it; and (iii) for whom should we sustain it

Improving Nuclear Safety, Security, and Nonproliferation in Northeast Asia through Multinational Approach

| December 31, 2016

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.
