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).

'What About China?' and the Threat to US–Russian Nuclear Arms Control

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

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 Overwhelming Case for No First Use

| Jan. 13, 2020

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

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.

A Tortoise Approach for US Nuclear Research and Development

| July 30, 2018

In Aesop's fable, a swift hare races with a deliberate tortoise. In the end, the tortoise wins by taking a slow and steady approach. The authors argue that, given the economic constraints on US deployment of nuclear power, a "tortoise strategy" is more prudent for US government nuclear R&D efforts.

US Nuclear Power: The Vanishing Low-carbon Wedge

| July 10, 2018

Nuclear power holds the potential to make a significant contribution to decarbonizing the US energy system. Whether it could do so in its current form is a critical question: Existing large light water reactors in the United States are under economic pressure from low natural gas prices, and some have already closed. Moreover, because of their great cost and complexity, it appears most unlikely that any new large plants will be built over the next several decades. While advanced reactor designs are sometimes held up as a potential solution to nuclear power's challenges, the authors' assessment of the advanced fission enterprise suggests that no US design will be commercialized before midcentury. That leaves factory-manufactured, light water small modular reactors (SMRs) as the only option that might be deployed at significant scale in the climate-critical period of the next several decades.
