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).

Transatlantic Dialogue: The Missing Link in Europe’s Post-Covid-19 Green Deal?

| April 2020

This policy brief emphasizes that the European Green Deal's effectiveness in a post Covid-19 world will require the involvement of strategic partners, especially the US. In the context of a potential US withdrawal from the Paris Agreement and the consequential vacuum, it will be even more important to engage the US in implementing the GD. In light of divergence between the US and the EU during past climate negotiations (e.g. Kyoto, Copenhagen, and Paris), we suggest a gradual approach to US engagement with GD initiatives and objectives.

Report

Emerging Issues in Economic Diplomacy

| April 2020

The nine issue papers contained in this report were proposed and written by graduate students at the Belfer Center for Science and International Affairs at Harvard Kennedy School. They present fact-based, nonpartisan analysis to help focus the next Administration on the key policy debates that must be resolved. And, they aim to create a platform for our students to engage with the most pressing policy issues of the day as they continue their careers in public service.

Factoring Pandemic Risks into Financial Modelling

| Apr. 01, 2020

Today’s economic crisis leaves us with an unsettling and perplexing regret. Why weren’t financial portfolios already adjusted for risks that stem from health events such as pandemics? After all, financial portfolios are adjusted for liquidity risks, market risks, credit risks, and even operational and political risks.

Insight 219: Singapore in the Global Energy Transition

| Dec. 03, 2019

For decades, Singapore has been a premier refinery hub and gatekeeper between Asia and the Middle East, but its position is increasingly threatened as producer countries are shifting into the downstream activities that helped make Singapore the “Houston of Asia”. Oil and petrochemicals drive about one quarter of Singapore’s net exports. Greater competition in the global oil and gas value chain could take a heavy toll on the city-state’s national budget and economic growth prospects.

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.
