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).

Nuclear Disarmament, Nuclear Energy, and Climate Change

| March 2019

Preventing nuclear war and avoiding catastrophic climate change are two of the most basic challenges facing human civilization in the twenty-first century. While these are separate issues, these challenges are linked in several ways, and both may be affected by the future of nuclear energy. For nuclear energy to provide any substantial part of the low-carbon energy needed in the second half of the twenty-first century would require dramatic growth. This chapter provides an overview of the constraints and risks of nuclear energy growth on that scale, and the necessary steps to address them. In particular, use of nuclear energy at that scale would place unprecedented demands on global systems for verification, control, and security for weapons-usable nuclear materials. Deep reductions in nuclear arms and their eventual prohibition will also require new approaches to managing the vast global stocks of weapons-usable nuclear materials. Politically, nuclear energy may not be able to grow on the scale required unless governments and publics are confident that it will not contribute to the spread of nuclear weapons, creating another link between climate mitigation and nuclear nonproliferation and disarmament.

In this edition of "The Interview," Fair Observer talks to Professor John Holdren, former science adviser to President Barack Obama and director of the White House Office of Science and Technology Policy from 2009 to 2017 about the impacts of global warming on the United States and the government's strategies to combat climate change.

Q&A with Elizabeth Sherwood-Randall

| July 12, 2017

Elizabeth Sherwood-Randall, former Deputy Secretary of Energy who has served in high-level positions at the White House and Pentagon, joined Harvard Kennedy School’s Belfer Center as a non-resident Senior Fellow in July. Sherwood-Randall is returning to the Kennedy School where she previously collaborated with Ash Carter, the Belfer Center’s newly appointed director, and Graham Allison, who stepped down as Center director this month. We asked Sherwood-Randall to give us some background on her Harvard connections, why she returned, and what she hopes to accomplish as a Senior Fellow.

With Growth of Coal Power Plants, Vietnam's Future Is Grim

| January 12, 2017

On January 12, 2017, the academic journal Environmental Science & Technology published a study by researchers from Harvard University, Greenpeace, and the University of Colorado Boulder titled “Burden of Disease from Rising Coal-Fired Power Plant Emissions in Southeast Asia.” Based on official data on the future installation of coal-fired power plants in Southeast Asia and atmospheric transport modelling, the research group presented a grim picture of regional air pollution due to emissions from these plants.
